The range of EM hold-open magnets provides the perfect complement to a technically and aesthetically advanced range of fire and smoke door products. Characterised by their ease of fixing and functional elegance, the EM magnets offer maximum reliability and service life.
The DORMA RMZ and RM frame and ceiling-mounted smoke detectors, supplemented where necessary by the RZ 01 power supply unit, provide the perfect complement to the very practical, thoroughly service proven DORMA TS 93 system for preventive fire protection.
The DORMA RMZ-K frame mounted smoke detector with its stabilised power supply unit supplies all the hold- open devices connected to it with 24 vDC, and in the case of an alarm or power failure, de-energises them to initiate their release (fail secure function).
