CROWCON Gasmaster 4 Channel Gas Detection Control Panel

Crowcon Gasmaster 4 Channel Gas Detection Control Panel

The Crowcon Gasmaster is a compact, versatile and powerful gas detection control panel that combines simple operation with an extensive array of input and output functions. Crowcon Gasmaster provides all the information you need about your gas and fire detectors at a glance.

The large multi-lingual display shows gas levels from all detectors simultaneously and enables system adjustment and testing using buttons on the front panel. Crowcon Gasmaster can operate ‘stand-alone’ or interface with any alarm devices and control systems using a selection of outputs.

This Crowcon Wall mounted control unit with LCD display is for up to four 4-20mA or mV pellistor-type gas detectors, fire zones (up to 20 heat/smoke detectors or call points per zone), flame detectors or ESU sampling units. It features RS-485 Modbus communications for DCS/PLC/SCADA connection, event logging, as well as dedicated drives for 12/24Vdc audible/visual alarms.

Double-pole relays with contacts rated 8A 250Vac (non-inductive) are supplied to indicate Alarm 1, Alarm 2 and Fault. 4-20mA or 1-5Vdc analogue outputs are provided per channel. Gasmaster operates from 90-264Vac and has 1.2Ah back-up batteries fitted as standard.

Display language options are available: English (as standard), French, Dutch, Spanish, German, Italian, Czech and Polish.
