1.1 About Gasmaster
Gasmaster is a gas and fire control panel, designed
to monitor remote gas and fire detectors.
Gasmaster can also monitor flame detectors as
well as GAS’s ESU product. The status of each input
is displayed on a large, clear LCD display, and
alarms or faults are indicated by clear LEDs and an
integral sounder.
Relay outputs are provided for alarms and faults, as
well as dedicated outputs for audible visual alarms.
An RS-485 Modbus output is provided for two-wire
transfer of all data to industry-standard control
systems.
Gasmaster logs all alarm and fault events so that
they can be investigated at a later stage using
Gasmaster PC software.
There are two versions of Gasmaster:
• Gasmaster 1 - single channel unit for one gas
detector, fire zone or ESU sampling device.
• Gasmaster 4 - four channel unit for one to
four gas detectors, fire zones or ESU sampling
devices.
Gasmaster 1 is identifiable from Gasmaster 4 by
having only a single channel display (see figure
3.2, page 18) and a de-populated terminal PCB. All
operating functions are identical to Gasmater 4.
Gasmaster is designed for simple operation, and all
day-to-day functions can be performed from the
front panel. Please refer to section 3 for details on
display operation.
