DUOmaster CO/LPG L
Detektor tlenku węgla CO i propanu-butanu LPG
The "DUOmaster CO/LPG L" dual-gas detector is used for continuous protection of premises at risk of carbon monoxide CO and propane-butane (LPG) emissions. Typical applications for the "DUOmaster CO/LPG 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, powered from 230V AC mains. It can operate as an individual device (stand-alone) or work with control panels and controllers.
Depending on the version, it can have different types of outputs:
relay - 3 relays, with NO contacts, signalling exceeding of the alarm thresholds Al1 and Al2 and of a 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)
LPG (propane-butane) : solid-state (non-selective, alarm thresholds: 10/30%DGW)
Visual signalling on the detector of power supply, exceeding of alarm thresholds, failures.
The detector consists of two modules : the main module (CO) and the LPG module connected by a cable.
Main module (CO) - PS plastic housing, cable entries (glands): 3 x PG11, PG16.
LPG module - PS plastic housing, cable entry (gland): PG16.
