The RZN 4408-K, RZN 4404-M and RZN 4408-M electric smoke vent control systems are mainly provided in building objects as e.g. industrial and office buildings, glass extensions or atriums. The controllers offer a high equipment standard and operation comfort. An integrated service timer for monitoring the maintenance rate, numerous connectible functions for alarms and faults and adjustable functions like a time limit for ventilation and stroke-arresting device are as much part of the standard of this system as internal fault and diagnostic indicators.
