The new 26SSD Smoke Shaft Damper designed specifically for shaft smoke control systems to meet the current standard BS EN 121010-8. The 26SSD has been fully tested to the requirements of the product standard to BS EN 1366-10 for Automatic Activation Systems and is a multi-compartment damper tested to BS EN 1366-2 in both directions.

Under the tests completed the damper will maintain its position in the open position for two hours and remain closed for two hours. The 26SSD combination unit is suitable for system pressures up to 500 Pa positive or negative.

The 26SSD Smoke Shaft Damper has been specifically designed for smoke shaft ventilation systems serving multi-storey commercial or residential properties. Its purpose is to open the area of incidence for smoke extraction while remaining closed in other areas, preventing the spread of smoke and maintaining its integrity in preventing the spread of fire. This unit has been fully tested in accordance with the harmonised standard BS EN 12101-8 and is suitable for automatic activation systems. It has been tested to BS EN 1366-10 in both directions and also tested to BS 1366-2 in both directions classifies the unit to be suitable for multicompartment. The unit is suitable for 500 Pa system pressure and tested up to 10,000 cycles, including additional cycles 10% under / 15% over voltage.

The 26SSD comprises three units—a damper, a removable sleeve, and a grille. The benefit of this design is that it is simple to install with various options and has easy access to maintain. The internals of the sleeve and damper are painted matt black as standard, so they are hidden from view to allow the grille on the face to have the largest free area of 90%. There is sufficient space between the damper and grille to avoid interference with the damper blade operation. The operation of the damper is controlled by a power open / power close actuator mounted at the bottom of the unit with cover plates for protection. Included within the housing is a junction box and glands for cabling connection on site.

The damper size tested was to suit a structural opening of 1,013mm wide x 1,998mm high, and that is the maximum size that can be supplied in one piece.
