The Crowcon Gasmaster 4 is a compact, versatile, and powerful gas detection control panel that combines simple operation with extensive input and output functions.
Gasmaster provides all the information you need about your gas and fire detectors at a glance. The large multi-lingual display simultaneously shows gas levels from all detectors and enables system adjustment and testing using buttons on the front panel. The Gasmaster gas detector control panel can operate ‘stand-alone’ or interface with any alarm devices and control systems using a selection of outputs.
A wall-mounted IP65 control unit with LCD display for four 4-20mA or mV pellistor-type gas detectors and fire zones (up to 20 heat/smoke detectors or call points per zone) flame detectors or ESU sampling units.
Features RS-485 Modbus communications for DCS/PLC/SCADA connection, event logging, and 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 backup batteries fitted as standard. Display language options are available: English (as standard), French, Dutch, Spanish, German, Italian, Czech and Polish.
Features
- All gas levels are displayed simultaneously – enabling complete systems status check at a glance
- Alarm messages can be customised to indicate the name or location of any detector in alarm
- The LCD can be set to display in many languages
- The menu system is intuitive and easy to use – enables configuration changes to be made easily
- All functions, from day-to-day operation to re-calibration, can be carried out from the front panel – routine testing can be performed rapidly
- Event log feature – enables system fault and alarm history to be viewed
- Provides analogue, relay and Modbus outputs – facilitating communication around the site
- Flexibility – Gasmaster can monitor up to four detectors in virtually any gas detectors, fire zones or Environmental Sampling Unit. The software enables re-configuration and event log upload in an instant
- Two levels of independent alarm per channel – can be configured to suit site requirements
- Remote inhibit and re-set facilities – enables control from any point on your site
- Compatible with a 4-20mA or mV pellistor-type gas detector – mV pellistor detectors reduce system purchase and maintenance costs
- Size 288 x 278 x 110 mm (11.3 x 10.9 x 4.3 inches). Weight 4.5kg (10lbs)
