General requirements
Manually-activated trigger devices can be either fixed or portable, with minimal design, function, and testing requirements Fixed trigger devices must generate an alarm signal via cable or wire-free means, which can be decoded by the local unit or controller Portable trigger devices, on the other hand, should generate wire-free alarm signals that are distinguishable from both fixed and automatically-activated devices If a portable trigger is solely for a social alarm system, it must be powered by primary (non-rechargeable) batteries Additionally, wire-free radio transmitter trigger devices and their associated receivers must comply with local radio regulatory requirements and applicable standards, transmitting an identification code with at least 256 different combinations when an alarm signal is activated.
Functional requirements
A trigger device shall be non-latching and require a single push or pull action by the user
Trigger device with internal primary batteries
Primary batteries must possess sufficient capacity to ensure the proper operation of the trigger device Even after 12 months of regular use, with one activation per day, the batteries should still be able to produce an alarm output signal detectable by the local unit or controller.
The trigger device must generate a fault warning signal to the local unit or controller when activated, ensuring that this occurs before the battery voltage drops below the manufacturer's specified minimum for the d.c supply input voltage (V B min.).
Trigger device with internal power supply connected to the a.c mains and
Trigger devices with internal power supplies connected to a.c mains and sealed rechargeable batteries must meet specific requirements They should operate correctly within a.c mains voltage variations of +10% to -15% without discharging the battery during normal conditions In the event of a.c mains interruption, the device must automatically switch to battery power without disconnecting the supply current The battery must have sufficient capacity to ensure proper functioning, allowing for alarm output generation after 24 hours of operation Additionally, a fully discharged battery should recharge to at least 80% of its nominal capacity within 24 hours and reach full capacity within an additional 48 hours The device must also provide a fault warning signal to the local unit within 2 hours of a.c mains failure and include a visual indication of normal a.c supply.

5 Test of manually-activated trigger devices
Test categories
The tests are divided into 3 categories: a) functional tests according to 5.5; b) wire-free radio transmission measurements according to 5.6; c) environmental tests according to 5.7.
Standard atmospheric condition for testing
Unless otherwise specified, the atmospheric condition in the laboratory shall be the standard atmospheric conditions for measurements and tests, specified in 5.3.1 of IEC 60068-1:1988 as follows:
– Air pressure: 86 kPa to 106 kPa (860 mbar – 1 060 mbar).
Number of trigger devices used for testing
Sequential testing is typically unnecessary, but it can be acceptable when only a limited number of trigger devices are available Ideally, each trigger device should undergo only one endurance test When more trigger devices are accessible, the testing duration and the stress placed on each device can be reduced.
The tests may be carried out in any order
The minimum number of various trigger devices needed for testing is determined by the specific type of trigger device and the designated environmental group for that device.
For type testing, it is advisable to allocate three of the available trigger devices for functional tests, while an additional three devices should be assigned for the free field transmission test, particularly if the trigger device operates on wire-free transmission.
General conditions for tests
The trigger device being tested must be installed in its standard orientation using the manufacturer's specified mounting methods Additionally, unless functional testing dictates otherwise, the device should remain in its normal operational condition.
The test setup for functional and environmental tests is determined by the power source and alarm output circuit of the trigger device The trigger device must be connected to the a.c mains or powered by d.c from an internal or external supply, as specified by the manufacturer, to ensure it operates correctly The voltage supplied to the trigger device should be adjusted to its nominal value unless otherwise stated in the test procedure Additionally, the trigger device should signal to an appropriate local unit or controller, and during certain function tests, it may also communicate with test equipment that monitors its status If the trigger device has separate outputs for external indicators or control circuits, these outputs should be monitored during testing as well.
Triggers using wire-free transmission
The trigger device being tested, along with the local unit or controller for functional testing, must be securely mounted in test fixtures and interconnected as outlined in Annex C (normative) throughout both functional and environmental tests.
Unless otherwise specified trigger device shall be provided with fresh batteries before start of testing
The local unit or controller, which is not included in the test specimen, must be powered throughout all tests using the nominal a.c or d.c supply voltage specified by the manufacturer.
Functional tests
5.5.1.1 Power supply powered from primary (non-rechargeable) batteries
The manufacturer must specify the maximum (V B max.), nominal (V B nom.), and minimum (V B min.) battery voltages before conducting the functional test First, disconnect the batteries and power the trigger device using an external variable DC supply Next, adjust the DC supply voltage to the nominal battery voltage (V B nom.) and verify that the trigger operates correctly in both the normal condition (output not activated) and the alarm state.
To ensure proper functionality of the trigger device, first adjust the d.c supply voltage to the maximum battery voltage, \$V_{B \text{ max}}\$; then, repeat the process with the supply voltage set to the minimum battery voltage, \$V_{B \text{ min}} \pm 1\%\$, as specified by the manufacturer.
Activate the trigger device and check that it goes into alarm condition (output activated) and that the battery low warning signal is initiated
5.5.1.2 Measurements of contact and insulation resistances for mechanical contact function
This subclause is relevant solely to trigger devices that utilize a mechanical contact function, such as a mechanical switch or relay, and do not incorporate electronic circuits for fault monitoring or alarm output generation.
The contact and insulation resistances shall be measured according to Annex A (normative) for all test samples delivered for testing before the start of any other tests
To ensure compliance, the contact resistance for each type of contact in the trigger device must be measured and found to be less than 100 mΩ, with any faults noted in the test report Additionally, the insulation resistance for each contact type should not fall below 10 MΩ.
Triggers using wire-free transmission
Unless otherwise specified the function tests are carried out with the trigger device and the local unit or controller mounted in the rf-shielded test fixtures as described in 5.4.2
To ensure accurate testing results, it is essential to minimize unwanted radio signal interferences that could activate the local unit or controller This may involve conducting tests in a shielded room when necessary.
5.5.2.2 Power supply powered from primary (non-rechargeable) batteries
The manufacturer must specify the values for V B max., V B nom., and V B min before conducting the functional test To begin the test, disconnect the batteries and power the trigger device using an external variable DC supply.
The trigger device and local unit shall be mounted in its normal orientation and the shielded test fixtures shall not be used
Before initiating the test, confirm that the fault warning or alarm signal from the trigger device is successfully received and decoded by the local unit or controller Additionally, with the direct current supply voltage set to the nominal battery voltage \( V_{B \text{nom}} \), verify that the trigger operates correctly in both normal conditions (when the output is not activated) and during an alarm.
To ensure proper functionality of the trigger device, first adjust the d.c supply voltage to the maximum battery voltage, \( V_{B \text{ max}} \) Next, lower the d.c supply voltage to the minimum battery voltage, \( V_{B \text{ min}} \), within ±1% as specified by the manufacturer, and verify that the trigger operates correctly.
Activate the trigger device and check that it goes into alarm condition (output activated) and that the battery low warning signal is initiated
The charger must automatically recharge the battery, restoring it to at least 80% of its rated capacity within 24 hours and fully charging it within an additional 48 hours Charging characteristics should adjust automatically based on ambient air temperature, adhering to the battery manufacturer's specifications Additionally, there should be no current draw from the battery when the trigger power supply is connected to the AC mains, even with voltage fluctuations ranging from +10% to -15% of its nominal value, while the trigger device remains in normal condition.
Portable trigger with neckband relief (anti-strangle) device
Portable neckband devices must include a strain relief mechanism designed to break under specific force conditions The testing of this trigger device should be conducted in its standard orientation.
The test jig illustrated in Figure B.1 is designed to evaluate the strain relief according to specific compliance criteria Firstly, the anti-strangle device must remain clear of the fixed pivots during testing Secondly, the strain relief device should withstand a vertical force of 25 N applied for 60 seconds without breaking Lastly, it is required that the strain relief device fails within 5 seconds when subjected to a vertical force of 40 N.
Push button fixed trigger types
All forces must be consistently applied for 4 seconds or until the trigger device is activated If the trigger device is activated by the force, it must occur within the first 2 seconds after the force is applied.
The button must activate the trigger device with a force of 5 N or more, while it should not activate with a force of 1 N or less Testing involves using a 10 mm diameter rigid rod with a hemispherical end placed at the center of the button When a force of 1 N is applied along the axis of operation, neither the switch nor the trigger device should activate Conversely, applying a force of 5 N with the same rod must successfully activate the switch and trigger device This test should be repeated at four additional locations around the button's perimeter, ensuring each location is maximally distanced from the others.
Mechanical endurance tests are performed by applying a force of 5 N to the center of the button, which should activate the trigger device as specified This test is repeated five times to ensure consistent activation After disconnecting the monitoring equipment, the button is subjected to the same force for a total of 1,000 repetitions Finally, the monitoring equipment is reconnected, and the initial test is repeated five more times, with the trigger device successfully activating each time.
Push button portable trigger types
All forces must be consistently applied for 4 seconds or until the trigger device is activated If the trigger device is activated by the force, this activation must occur within the first 2 seconds after the force is applied.
Wire-free radio interconnections measurements
For both fixed and portable trigger devices utilizing wire-free radio connections to communicate with local units or controllers, it is essential to measure key radio parameters of the transmitter in accordance with EN 300 220-2:2010, as outlined in Table 1.
The most important radio transmitter parameters as described in Table 1 shall be measured and the results published by the manufacturer in the user documentation or in a separate data sheet
Table 1 – Measurement of radio transmitter parameters
Subclause Methods of measurement according to EN 300 220-2
5.1.3.1 Frequency error (measurements shall be carried out under normal test conditions according to 5.3 and extreme test conditions according to 5.4)
5.1.3.3 Effective radiated power (radiated) (see a)
In extreme test conditions, as outlined in section 5.4, the minimum recommended power level for optimal performance of a portable trigger device, when used with a local unit or controller in a domestic setting, ranges from 0.1 mW to 2 mW.
When the portable trigger device is used beyond the local domestic environment a minimum radiated power level in excess of 2 mW is recommended
The minimum radiated power levels are applicable for the frequency range of 500 MHz to 1,000 MHz For frequencies ranging from 137 MHz to 500 MHz, the previously mentioned values must be adjusted according to Equation (1).
Effective minimum radiated power level = p × (f/500) 4 (1) where f is the frequency in MHz
NOTE The mandatory type approval of the radio transmitter required by the national regulatory authorities is not covered by this standard.
Environmental tests
All trigger devices shall be subjected to environmental testing according to the following
International standards: IEC 62599-1 and IEC 62599-2
The purpose of environmental testing is to demonstrate that the equipment can operate correctly in its service environment and that it will continue to do so for a reasonable time
Components for social alarm systems are, however, installed in many different environments but it would be impractical to test every aspect of all conceivable environmental conditions
The intensity of testing determines how well the equipment can endure potential failure mechanisms that may arise from the surrounding environment during regular operation.
Additional precautions may be necessary, in particular installations, where some aspects of the environment can be identified as being unusually severe
The tests aim to reveal failures caused by realistic service environments, although some significant failure mechanisms develop gradually under these conditions To conduct tests efficiently and economically, it may be necessary to accelerate these changes by intensifying environmental parameters or increasing the duration or frequency of their application.
The tests are divided into two classes: a) Operational tests
The tests evaluate the specimen under conditions that mimic its service environment, aiming to confirm the equipment's capability to function properly and endure typical operational conditions, as well as its resistance to specific environmental factors.
The specimen is operational and its condition is monitored, with functional testing conducted during the conditioning process as specified for the relevant trigger device Additionally, endurance tests are performed to assess its reliability and performance.
In these tests the specimen is subjected to conditions more severe than the normal service environment in order to accelerate the effects of the normal service environment
The purpose of these tests is to evaluate the equipment's durability against the long-term impacts of its service environment These assessments focus on the residual effects rather than immediate responses, which is why the specimen is typically not powered or monitored during the conditioning phase, as outlined for the specific trigger device.
Selection of tests and severities (environmental groups)
The IEC standards listed in 5.7.1 specify the tests and severities to be used for each of the following four environmental groups which are applicable for fixed or portable equipment
Portable devices expected to be transported between two of the groups during use shall be specified and tested as the group with the highest number
Groups I, II, III and IV are progressively more severe, and therefore Group IV equipment may be used in Group III applications, etc
The following environmental groups can be selected:
I Indoor but restricted to residential environment (e.g living rooms and bedrooms)
II Indoor in general (e.g stairways, manufacturing and assembly areas, entrances and storage rooms)
III Outdoor but sheltered from direct rain and sunshine, or indoor with extreme environmental conditions (e.g garages, balconies, lofts and barns)
Tests applicable to the different environmental groups
Tables 2 and 3 give the types of environmental tests that shall be carried out for the different environmental groups selected for fixed or portable trigger devices
Environmental test exposures not applicable to different types of triggers
Trigger devices differ in construction and some of the environmental test exposures are not applicable to all types of trigger devices a) Mechanical fixed trigger type
The following environmental exposures shall not be carried out:
– mains supply voltage dips and short interruptions;
– conducted disturbances induced by electromagnetic fields;
– slow high energy voltage surge b) Battery powered fixed trigger type using cable transmission
The following environmental exposures shall not be carried out:
– mains supply voltage dips and short interruptions c) Battery powered fixed or portable trigger type using wire-free radio transmission
The following environmental exposures shall not be carrried out:

Specific environmental test requirements for different types of trigger devices
5.7.5.1 Fixed trigger types using cable transmission
Conditions under which fixed trigger types using cable transmission are tested a) Monitoring during exposure
All operational tests must include monitoring of the trigger device to prevent any unwanted alarms or fault transmissions to the local unit or controller, ensuring that the status of all indicators, both acoustical and optical, as well as control outputs, remains unchanged Additionally, a reduced functional test should be conducted in relation to the environmental tests.
A reduced functional test shall be carried out before, after and in some cases during an environmental exposure
Depending of the construction of the fixed triggers the following reduced functional tests shall be carried out:
Before and after each environmental test, the contact and insulation resistance of the output contacts of a fixed trigger device with a mechanical contact function for the alarm output must be measured as outlined in Annex A (normative) It is important to note that no measurements should be conducted during the environmental exposures.
The measured values must adhere to specific limits: i) each contact type in the trigger device should have a contact resistance of less than 100 mΩ, with any faults encountered during measurements documented in the test report; ii) the insulation resistance for each contact type must be no less than 10 MΩ.
NOTE If the mechanical contact function is a mechanical contact which activates an electronic switch, test 1) above does not apply and test 2) below is applied
To ensure the fixed trigger device functions properly, verify that its electronic circuits can generate the trigger output signal effectively This can be accomplished by connecting the device to suitable monitoring equipment or a local unit that can accurately receive and decode the alarm triggering signals from the device being tested.
Ensure that the fixed trigger device, which includes electronic circuits powered by the a.c mains with an internal battery backup or from a local unit or controller, can effectively provide an output power failure signal when the external main power (either a.c or d.c.) is turned off.
4) If the fixed trigger has any indicators (optical or acoustical) fitted, these indicators shall be checked for correct operation during reduced functional testing
5.7.5.2 Fixed or portable trigger types using wire-free radio transmission
Conditions under which fixed or portable trigger types using wire-free radio transmission are tested a) Use of rf-shielded test fixtures during the environmental testing
The trigger device, along with the standard receiver or local unit used for its testing, is typically installed in RF-shielded test fixtures as outlined in section 5.4.2.
The attenuation values A T (1), A T (2), and A T (3) are measured with the equipment securely mounted in the fixtures and the fixtures properly closed However, during certain environmental exposures, it may be necessary to open the fixtures or remove the equipment under test.
The trigger device, secured in its test fixture, will be positioned inside the climatic chamber, while the local unit or controller and the RF attenuator will remain outside the chamber.
The test fixture inside the climatic chamber shall be opened during the exposure period apart from the time periods where reduced functional tests shall be carried out
Before beginning the test, ensure that the local unit or controller can receive and decode any fault warning or alarm signals sent from the trigger device.
Only the trigger shall be exposed and the test fixture shall only be used for reduced functional testing before and after the exposure
5) Damp heat, steady state (operational)
6) Damp heat, steady state (endurance)
Only the trigger shall be exposed and it shall only be mounted in its rf-shielded test fixture during reduced functional testing before and after the exposure
The local unit or controller monitors the trigger device throughout the exposure, including the submersion period, to prevent any unwanted alarm or fault signals Prior to and following the test, the local unit or controller must be securely mounted in its RF-shielded test fixture for reduced functional testing.
Typical automatically-activated triggers
Example Gas detectors for flammable and toxic gases
Common requirements
Alarm calls generated by different automatically-activated triggers in a dwelling must be easily distinguishable from one another, as well as from those produced by manually-activated triggers.
Operation of automatically-activated trigger
Operation of any automatically-activated trigger, whether it provides a momentary or continuous signal, shall not affect the operation of the manually operated call activation
Response to an automatically-activated trigger
The local unit or controller or trigger device associated with automatically-activated triggers shall be capable of disabling and enabling the response from automatically-activated triggers.
Specific requirements for fire, gas, intruder alarm triggers
The requirements for fire, gas, and intruder alarm triggers are outlined as follows: a) Trigger devices mentioned in section 6.1.1 must adhere to the relevant EN 54 series standards for fire alarm system components; b) Trigger devices specified in section 6.1.2 are governed by the applicable IEC standards, including IEC 61779-1, IEC 61779-2, IEC 61779-3, and IEC 61779-4.
The IEC 61779-5 standards outline the requirements for gas alarm system components, specifically addressing the testing and requirements for trigger devices as specified in section 6.1.3 For these trigger devices, relevant references are made to the applicable IEC 62599 series standards concerning intruder alarm system components.
Information to be included in the marking
The trigger devices shall be marked with the following:
– name of manufacturer or supplier;
– date of manufacture or batch number or serial number;
Requirements for the marking
The marking shall be legible and durable
In situations where marking space for the trigger device is restricted, codes can be utilized, provided they are detailed in the accompanying documentation, enabling cross-referencing to the necessary information.
Measurements of contact and insulation resistances for mechanical contact function
General
For each type of contact in the trigger device the contact resistance shall be measured ten times and the insulation resistance shall be measured once
NOTE If the mechanical contact function is a mechanical contact which activates an electronic switch, the test method described in this annex does not apply.
Measurements of contact resistance
The contact resistance shall be measured in accordance with the requirements of
IEC 61020-1, under the following conditions:
Test voltage by open contact: 20 mV peak
Test current: 100 mA max or as specified by the manufacturer if less than
The test sequence involves the following steps: first, ensure the contact is closed (or maintain it in a closed state if it is normally closed); next, apply the test voltage; then, measure the contact resistance; finally, open the contact (or perform an open and close action if it is normally closed).
If the measurements are carried out after the environmental exposure the contact shall only have been activated once
The resistance of interconnecting wires and fixed mounted cables is measured initially, and this value is then subtracted from the total resistance measured to obtain accurate results.
Measurements of insulation resistance
The insulation resistance shall be measured in accordance with IEC 60341-1:1970, 13.4 under the following conditions:
Test voltage: (100 ± 15) V d.c or as specified by the manufacturer if less than 100 V d.c
The insulation resistance shall be measured at the end of the given duration of the exposure
Fixed pivots of 12,5 mm radius
Figure B.1 – Strain relief test jig
Test set-up by using rf-shielded test fixtures
RF-shielded test fixture for the trigger device
The trigger device must be installed in a test fixture that meets specific requirements, as illustrated in Figure C.1 This fixture should be an RF-shielded metal casing that effectively dampens RF fields from the trigger to prevent any unintended activation of the corresponding receiver Additionally, the signal from the trigger device is captured by a stripline antenna within the casing, which is linked to a 50 Ω connection plug.
Wave Ratio (V.S.W.R.) shall be below 5 c) The casing shall be of sufficient size to contain:
A controlled power source is essential for powering the trigger device as outlined in the test procedure, allowing for adjustable direct current (d.c.) supply input voltage to meet specific requirements.
2) rf-attenuation component, if necessary, to reduce the output level;
The RF power amplifier is designed to enhance the output level, ensuring that the mechanical positioning of the trigger device is reproducible, maintaining an output variation of no more than ±1 dB after removal and remounting A small hole in the fixture allows for external manual activation of the trigger device using a non-conducting activation rod for push button types, or a rigid or flexible link for pull switch types Additionally, the fixture must remain unaffected by various environmental test exposures, with output levels not deviating more than ±1 dB, necessitating the avoidance of dielectric materials that alter their relative dielectric constant under varying temperature and humidity conditions.
The primary goal of utilizing a test fixture is to transform free field transmission into a cable signal transmission scenario, ensuring high reproducibility of tests and minimal interference from surrounding environments.
RF-shielded test fixture for the local unit or controller
The test fixture for the local unit or controller, as illustrated in Figure C.1, should be built similarly to the trigger device fixture However, achieving effective screening is more challenging due to the presence of mains and telephone cables within the screened casing It is essential that the free field coupled signal level between the two test fixtures remains significantly below the receiver sensitivity threshold of the local unit or controller.
Interconnection between trigger device and local unit or controller
The two fixtures as described in C.1 and C.2 above are interconnected by shielded cables with the rf-attenuator connected in series with the signalling lead

– Partie 3: Unité locale et contrôleur
– Partie 7: Lignes directrices pour l'application (à l'étude)
A social alarm system offers a continuous 24/7 service for alarm activation, identification, signal transmission, alarm reception, archiving, and duplex voice communication This system aims to provide peace of mind and assistance to individuals residing in their homes or in monitored locations deemed at risk.
Un système d’alarme sociale est constitué d’un certain nombre de parties qui peuvent être configurées de différentes manières afin de réaliser cette fonctionnalité
A user can request assistance using a manually activated triggering device, resulting in an alarm trigger signal In some cases, alarm trigger signals may be generated by automatic triggering devices A local unit or controller receives the alarm trigger signal, switching from a normal condition to an alarm condition and displaying this for the user Some systems incorporate an optional pre-alarm condition, allowing the user to reset the alarm signal for a brief period.
Le contrôleur transmet normalement la condition d’alarme au centre de réception d’alarme
The Alarm Receiving Center (ARC) operates through an alarm transmission system, which can be located either locally or remotely from the controller It has the capability to identify the local unit and the type of alarm, establishing a two-way voice communication channel between the alarm recipient and the user The alarm recipient offers assistance to the user and directs help appropriately.
In certain situations, the alarm can be redirected to a recipient using a personal receiver The alarm is identified by the recipient, and a duplex voice communication channel is established between the user and the acknowledged alarm recipient through the controller Additionally, the system records the time, date, location, and type of alarm in all cases.
