Smoke Ventilation Control Panel 2 lines 2 drive groups 4A

RZN4404-M - Smoke Ventilation Control Panels 24VDC/4A, 2 Lines, 2 Drive Groups

The RZN 4404-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.
