DUOmaster CO/NO2 L
Detektor tlenku węgla CO i dwutlenku azotu NO2
The "DUOmaster CO/NO2 L" dual-gas detector is used for the continuous protection of rooms at risk of carbon monoxide CO and nitrogen dioxide (NO2) emissions. Typical applications for the "DUOmaster CO/NO2 L" detector include garages and underground car parks. It is a stand-alone unit which is a combination of a detector and a control unit and is powered from the 230V AC mains. It can operate as an individual device (stand-alone) or work in conjunction with control panels and controllers.
Depending on the version, it can have different types of outputs:
- relay - 3 relays, with NO contacts, signalling the exceeding of alarm thresholds Al1 and Al2 and failure
- digital - RS485 link, Modbus-RTU protocol, addressable detector.
Sensors used:
- CO carbon monoxide: electrochemical, (selective, measurement or two-threshold detection, alarm thresholds: 40/100ppm, 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): 3 x PG11, PG16.
NO2 module - PS plastic housing, cable entry (gland): PG16.
Versions:
- DUOmaster CO/NO2 L /EE/D - electrochemical CO sensor, electrochemical NO2 sensor, relay outputs (NO type)
- DUOmaster CO /NO2L /EE/D/RS485 - electrochemical CO sensor, NO2 electrochemical sensor, relay outputs (type NO), RS485 output with Modbus RTU protocol
