DUOmaster CO/NO2 H
Detektor tlenku węgla CO i dwutlenku azotu NO2
The "DUOmaster CO/NO2 H-B" detector is designed for use in stationary carbon monoxide (CO), and nitrogen dioxide (NO2) detection systems outside potentially explosive atmospheres. Typical applications for the "DUOmaster CO/NO2 H-B" detector include detection systems in garages and underground car parks. The housing (through the use of cable feed-throughs) is suitable for installation in flush-mounted wiring systems. The "DUOmaster CO/NO2 H-B" detector is designed for cooperation with control panels or controllers via the RS485 bus. Wide range of supply voltage - nominal 24 V DC, possible 12-28 V DC. Digital output - RS485 connection, Modbus RTU protocol, addressable detector.
Sensors used :
- carbon monoxide CO : electrochemical, (selective, two-threshold measurement or detection, alarm thresholds : 40/100ppm, measuring range 0...500ppm)
- NO2 nitrogen dioxide : electrochemical, (selective, dual threshold detection, alarm thresholds : 3/6ppm).
Visual indication on the detector of power supply, exceeding of alarm thresholds, failure .
The detector consists of two modules: the main module (CO) and the NO2 module connected by a cable (flush mounted).
Main module (CO) - PS plastic housing, cable bushings - 3 pcs. (power supply, RS485 output, connection to NO2 module).
NO2 module - PS plastic housing, cable entry - 1 pc. (for connection to main module)
