Powered Pressurisation Fan Systems:
In a residential/apartment building fire, a smoke control ‘pressurisation’ is often employed to ensure that escape routes are kept clear of smoke to allow safe, calm movement of residents towards the fire escapes and to make fire fighters’ difficult job easier by improving visibility and providing clear firefighting areas such as stairwells and lobbies.
Stairwell pressurisation – smoke safety equipment must be properly set up to remove the risk of over-pressurisation (jamming doors shut) or under-pressurisation (allowing smoke to move too freely).
Controls – a smoke safety system can only operate if its control system is in full working condition. Brakel Airvent can maintain any make of control unit, be it closed or open protocol.
Test standards and sequence – Service checks/tests must comply with BSEN 12101-6 and should be carried out at least once every 12 months (6 monthly operational service checks are also recommended), in addition to weekly and monthly testing/checks which will be usually carried out by on site personnel, with results to be entered into a log.
Results – All results obtained from testing should be compared with the initial “acceptance/commissioning” test results. Any major discrepancies should be reported immediately and acted upon.Request a quote
