Smoke Ventilation Window FSP P1

Control units

Control units RZN, 4402-K, 4404-K, 4408-K


Control units are used for operating motors in the event of a fire as well as daily building ventilation. It is possible to connect OSD rain sensor, ZRD rain sensor, RT 45 alarm buttons, LT 84U ventilation switch. The control unit works in monitoring mode on a daily basis and is supplied from 230V AC mains. In case of a fire, the rain sensor sends a signal to the control unit which, in turn, automatically sets in motion the window motors. Because of safety considerations, the control unit is equipped with an independent power backup which allows it to work in the monitoring mode for 72 h.

ZRD rain sensor

It ensures automatic window closing in case of rain. It can co-operate with RZN 440_ - K control units. The sensor is heated, hence it is insensitive to such interference as mist, dew etc. It is installed in the open area of the roof, directly exposed to weather conditions. The signal from the sensor is accepted only when the control unit is monitoring. In the event of fire, signals from the sensor are ignored and have no effect on the window operating. ZRD rain sensor
