A.7.1 Planning
The planning of an individual installation of a hold-open system in an individual building and the selection of its components should only be carried out by specialists or trained personnel. The instructions of the manufacturer of the hold-open system and/or control unit should be followed closely. Local conditions such as environmental influences (e.g. high or low temperatures, dusty atmosphere, humidity) and user-specific requirements (e.g. high frequency of release, operational location, traffic, security) should be considered in regard to the components of the hold-open system to be chosen.
The planning office should ensure the correct selection of the components of the hold-open system.
A.7.2 Installation
The installation and assembly of the hold-open system on the building side should be carried out by skilled personnel who are conversant with all the required trades and with the relevant local and national legislation.
NOTE Attention is drawn to national and local legislation covering the installation and assembly of the hold-open system on the building side and users' obligations there under.
The installation instructions of the manufacturer of the hold-open system and/or control unit should be followed.
The installation contractor should be responsible for the correct installation of the hold-open system and for handing over to the building manager the requisite product information in accordance with 6.2.2.
Annex B (informative)
Recommendations for installation and fixing of the hold-open system
B.1 The fixing instructions should be carefully followed during installation. These instructions and the maintenance instructions should be passed on to the user by the installer.
B.2 In the case of doors that are held open by hold-open systems, the area/range/sweep necessary for the closing operation to be performed should be kept constantly clear. To help to achieve this, the area should be clearly identified by lettering, floor markings or similar.
No blocking device of the door, even if removable, should exist on the door or at its proximity.
Where necessary, structural measures should also be implemented to ensure that lines, pipe leads, cables, storage goods or components, (e.g. false ceilings or their components), are reliably prevented from falling into the area to be kept clear.
B.3 The fixings of hold-open devices should not impair the protective function of the fire/smoke door assembly. In cases of doubt, system integrity should be verified by appropriate tests, e.g. EN 1634. Care should be taken that any fixings or preparation of the fire door assembly does not reduce its fire integrity.
B.4 It is recommended that anchor-plates for hold-open magnets be secured to the leaves of swing doors so that the fixing screws are not more than 150 mm from the top or bottom edge of the door leaf. The fixing position should be as far as possible away from the centre-line of the door hinges. In steel doors, where no supporting structures are provided, (e.g. internal brackets), tapered draw nuts should be used in conjunction with the screws provided by the manufacturer.
B.5 For swing doors, manual release forces at the door handle position are recommended to be between 50 N and 100 N.
If after installation the manual release forces are found to be too high a local push-button for manual control should be fitted. If the manual release forces are found to be too low, a higher hold-open power size should be used. If hold-open devices with adjustable power are being used, in above cases the power should be adjusted accordingly.
B.6 Flexible cables should be protected against trapping between door edges and the door-frame, by means of armoured loops or equivalent.
B.7 Other functions, not covered by this European Standard, associated with electrically controlled hold-open systems can also be provided. However, such functions are not to negatively affect the release performance of the hold-open system.
Annex C (informative)
Recommendations for acceptance inspection of the hold-open system
Following the installation on site of the hold-open system ready for operation, its functional integrity and quality of installation should be confirmed by an acceptance inspection procedure.
Manufacturers of control units and hold-open devices should provide documents in which the attention of the user and/or building manager is drawn to this acceptance inspection recommendation. The inspection should normally be arranged by the building manager, unless another person has been made responsible for the arrangements.
The acceptance inspection should be performed by skilled personnel authorized by the above manufacturers, or from an accredited test/inspection agency.
The acceptance inspection should encompass verification of at least the following:
a) The installed components of the hold-open system should be in accordance with the components indicated in the list of approved components (see Annex G).
b) The accompanying information of the components installed should be in accordance with the description of the hold-open system contained in the product information supplied with the product (see 6.2).
c) The interaction of all the components should be examined against the requirements indicated in this European Standard, with the initiation event being tested both by simulation of the fire parameter of the detectors, and also by manual operation.
d) A test should be performed to ensure that the door is released for self-closing if the hold-open system becomes inoperable (e.g. through the removal of a detector, interruption of power supply or other comparable actions).
e) The installation of the hold-open system should be in accordance with the fixing instructions of the manufacturer.
Once the acceptance inspection has been successfully completed, the person who performed the acceptance inspection should permanently fix on the wall in the immediate vicinity of the door, a plate measuring at least 30 mm × 40 mm and carrying the inscription:
HOLD-OPEN SYSTEM
Acceptance inspection by:
company name or trademark, month and year of acceptance inspection
The person who performed the acceptance inspection should provide a certificate detailing the result of the inspection to the building manager. This certificate should be retained by the building manager (see Annex D).
