Tmaster CO/LPG/NO2 H
Detektor tlenku węgla (CO), propanu-butanu (LPG) i dwutlenku azotu (NO2)
The "Tmaster CO/LPG/NO2 H-B" three-gas detector is designed for use in stationary detection systems for carbon monoxide (CO), propane-butane (LPG) and nitrogen dioxide (NO2) outside potentially explosive atmospheres. Typical applications for the "Tmaster CO/LPG/NO2 H-B" detector are 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 "Tmaster CO/LPG/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, measurement or two-threshold detection, alarm thresholds : 40/100ppm, measuring range 0...500ppm)
- propane-butane (LPG) : solid-state (non-selective, alarm thresholds : 10/30%DGW)
- 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 (CO) module and the LPG/NO2 module connected by a cable (flush mounted).
Main module (CO) - PS plastic casing, cable bushings - 3 pcs. (power supply, RS485 output, connection to LPG/NO2 module).
LPG/NO2 module - PS plastic casing, cable grommet - 1 pc. (for connection with main module)
