BS EN 15650 - Ventilation for Buildings - Fire Dampers
Section 8.3 states regular testing/inspection should be undertaken to meet regulatory requirements, or at intervals not exceeding six months. A comprehensive example of the maintenance procedure is given in Annex D of the standard. Some automatic systems may allow more frequent testing (48hr or less) and this may be required by a national standard.
BS 9999 - Code of Practice for the Fire Safety in the Design, Management and Use of Buildings - Annex V
V.3.5 Smoke Control Systems
For means of escape states actuation of the system should be simulated once a week. It should be ensured that any fans and powered exhaust ventilators operate correctly, smoke dampers close (or open in some systems), natural exhaust ventilators open, automatic smoke curtains move into position, etc.
V.5 Three Monthly
In addition to the checks recommended in V.2, V.3 and V.4, the actuation of all smoke control systems should be simulated once every three months. All zones should be separately tested and it should be ensured that any fans and powered exhaust ventilators operate correctly, smoke dampers close (or open in some systems) etc.
In addition to the checks recommended in V.2 to V.6 arrangements should be made for annual inspections and tests of the following to be carried out by competent persons, for any defects to be logged and the necessary action taken, and for certificates of testing to be obtained.
Approved Document B, Volume 2
Clause 10.12 states adequate means of access must be provided to allow inspection, testing and maintenance of both fie damper and its actuating mechanism.
BS 9999 - Code of Practice for the Fire Safety in the Design, Management and Use of Buildings - Annex W
Maintenance of air conditioning and ventilation equipment including air filters, motors, fe dampers and their controls, smoke detectors and alarms is of paramount importance both in preventing fie and in ensuring that measures taken to mitigate its consequences are effective when needed.
Arrangements should be made for all fie dampers to be tested by a competent person on completion of the installation and at regular intervals not exceeding 2 years. They are to be repaired or replaced immediately if found to be faulty. Spring operated fie dampers should be tested annually and fie dampers in dust laden and similar atmospheres should be tested much more frequently, at periods suited to the degree of pollution.
