RZN 4402-K / RZN 4404-K
The VdS-approved electric control system RZN 4402-K (-KS) and smoke vent control panel RZN 4404-K (-KS) are particularly designed for the use in small buildings e.g. staircases.
The controllers convince as they offer a high equipment standard and operation comfort. An integrated service timer for monitoring of the maintenance rate, numerous connectible functions for alarm and fault and adjustable functions like time limit for ventilation and strokearresting device are just as well part of the standard of this system as internal fault/ and diagnostic indicators
