Dry roof - Waterproof roof
The XPJ360B SINGLE ZONE BIFONCTION CO2 pneumatic smoke controllers (D.C.M.*, D.A.C.* ou D.C.M.R.*) are designed to issue an opening order by percussion of single-use A.P.S (CO2 cartridges) to Natural Smoke and Heat Exhaust Ventilators (NSHEV). They allow the opening of smoke extraction devices with a push button control. The BIFONCTION model has a ventilation opening - closing command. The smoke extraction function always has priority over the ventilation function. The standard ranges are equipped with a deformable membrane and are accessible at level 0 (§4.1 of NF S 61-931). It is possible, on request, to make adaptations of the standard enclosures with, for example, vandal-proof doors for access to level 1 (§4.2 of NF S 61-931), or cabinets (D.C.M.R.*) with a number of strikers to be determined.
