mcr 9705 smoke exhausting control unit is used to activate devices of MERCOR electric desmoking system based on alarm signal from thermal or optical smoke sensors, from manual fire alarming devices (red call point buttons), or from another control unit (e.g. fire alarm system, building automatics system). The control unit is supplied from 230 V alternating current and feeds 24V= voltage to electric desmoking system devices. Thanks to its batteries, the control unit is not exposed to power shortage, and may stand-by for 72 hours from power failure, with a single toggling of devices possible after that time (e.g. opening smoke vent flaps).
mcr 0204 desmoking control unit is a control device for electric smoke exhausting system. mcr 204 unit is used for activating electric systems of MERCOR smoke exhausting system based on alarm signal from thermal or optical smoke sensors, and manual desmoking buttons (so-called manual call point buttons). The device is supplied with 230 V~ alternating current, the output operating voltage is 24 V-. The control unit includes batteries allowing for operation of the system for 72 hours from mains voltage failure - a single alarm opening of flaps or smoke windows is possible after that time.
actuators are used for opening flaps and windows of smoke exhausting system, as well as for daily ventilation. They are supplied by 24V- direct voltage. Casings cover is made of anodized aluminum. In standard, they feature anti-interference condenser, overload switch and limit switches.
