How often does a smoke ventilation system need to be tested?
BS EN 12101 and BS 9999 set out the frequency of tests and what should be checked. All in all, there are three types of services – weekly, monthly and annual. It is essential and mandatory that smoke control systems are serviced annually by a competent person. Additionally, weekly and monthly tests should be performed to ensure the system is fully operational throughout the year.
Weekly Operational Tests
Weekly tests of the system should be carried out to check the operation of the system. For mechanical systems, checks should be made to determine whether the fans are running satisfactorily and that the ventilation system has operated. Where there is a backup generator in place, the fuel level should be checked and topped up as necessary.
Monthly tests should be carried out in addition to weekly tests. During the monthly test, the failure of the primary power supply should be simulated and a check made that the system has automatically switched over to the secondary power supply. Where the secondary supply is via a backup generator or power cell (battery or UPS), the secondary supply must be able to energise the system for a minimum of three hours. A zero airflow condition should be simulated to check that the system switches automatically to the standby fan/s and that they are running satisfactorily.
