Description
The ART is a single channel, non-dispersive infrared refrigerant gas detector with a display and relay that can be used as a stand alone system or integrated into a building management system (BMS). The fast responding infrared sensor accurately detects refrigerant gas leaks without cross interference from toxic or combustible gases, minimizing false alarms. It offers Modbus® output to a BAS and may be connected as an analog transmitter or a Modbus® transmitter.

The ART is compatible with the QCC and the FCS as either an anolog or digital transmitter.
