The Crowcon Gasmaster control panel is used to monitor toxic and flammable gases. The wall-mounted device displays all gas levels simultaneously on a large, multilingual LED display, allowing full system status checks at a glance.
The Gasmaster can monitor up to four channels, with two levels of alarm per channel, allowing it to monitor virtually any combination of flammable and toxic gas detectors, oxygen detectors and fire detectors (smoke, heat or flame).
All alarms and faults are recorded in an 'event log' which can be accessed regularly.
Analog outputs and RS485 digital communications allow the control unit to be connected to PLC/DCS/SCADA systems, a PC, a chart recorder or data logger. An integral 85 dB multi-tone sounder is fitted as standard. Battery backup is also provided as standard.
Relays can operate in 'fail-safe' mode and all coils are actively monitored so Gasmaster can warn if a relay fails. In its alarm state, both visual and audible warnings are activated. Further relays are provided to control other equipment including ventilation systems, status lights and valves, depending on the alarm state of the control unit.
Installation and maintenance is simple, with space for cable glands and termination of wiring.
