The RZN 4408-K, RZN 4404-M and RZN 4408-M electric smoke ventcontrol systems are mainly provided in building objects as e.g. industrial andoffice buildings, glass extensions or atriums. The controllers offer a highequipment standard and operation comfort. An integrated service timer formonitoring the maintenance rate, numerous connectible functions for alarms andfaults and adjustable functions like a time limit for ventilation andstroke-arresting device are as much part of the standard of this system asinternal fault and diagnostic indicators.
