Zeta Duct Unit Enclosure

The Zeta Duct unit allows air in a ventilation duct to be monitored for smoke via a smoke detector mounted outside the duct - in a sealed chamber.

The unit comes supplied with 2 sampling probes, one in, one out, which are mounted through the duct, in the center of the airflow. For a reliable smoke detection, the airspeed in the duct must be at least 2.5 m/s. The unit can be powered from either 230V AC or a separate 24V power supply. The unit has form C relay outputs for Alarm and for fault.
