DUOmaster CO/NO2 G
Detektor tlenku węgla CO i dwutlenku azotu NO2
The "DUOmaster CO/NO2 G" two-gas garage detector is used for the continuous protection of rooms at risk of carbon monoxide and nitrogen dioxide (NO2) emissions. Typical applications for the "DUOmaster CO/NO2" detector include garages and underground car parks. The "DUOmaster CO/NO2 G" detector is designed for use with typical control panels or controllers. Power supply 12 V or 24 V DC.
Depending on the version, it can have different types of outputs:
- current: continuous (4-20mA), or dual threshold 4/8/12mA
- OC voltage type (NC or NO), two outputs signalling exceeding alarm thresholds Al1 and Al2.
- digital - RS485 connection, Modbus RTU protocol, addressable detector.
Sensors used:
- Carbon monoxide CO : electrochemical, (selective, measurement or two-threshold detection, alarm thresholds: 40/100 ppm, measuring range 0...500ppm ).
- Nitrogen dioxide NO2 : electrochemical, (selective, measurement or dual threshold detection, alarm thresholds: 3/6 ppm, measuring range 0...20ppm ).
Visual indication on the detector of power supply, exceeding of alarm thresholds, failure.
The detector consists of two modules: the main (CO) module and the NO2 module connected by a cable.
Main module (CO) - PS plastic housing, cable entries (glands) : PG11 + PG9 (only /RS485 versions), PG16.
NO2 module - PS plastic housing, cable entry (gland): PG16
