Smoke detector RM / WM 3000 EX

Fire protection components installed in hazardous areas require in addition to the approval for fire protection a test with certificate confirming their compliance with EN 94/9/EG (ATEX 100). Both smoke and heat detectors RM3000IS EX and WM3000IS EX meet these requirements. The RM 3000IS EX smoke detector is a stray light detector with integrated thermal sensor. The RM 3000IS EX smoke detectors and WM 3000IS EX heat detectors are intrinsically safe. In hazardous areas they may only be used in combination with a shunt safety barrier. To ensure the correct functioning of the hold-open system, the DICTATOR smoke and heat detectors have to be replaced after a maximum of 8 years of operational life. In Germany the DIN 14677 regulates the replacement obligation of fire detectors in hold-open systems.
