1.1 About Gasmaster
Gasmaster is a gas and fire control panel,
designed to monitor remote gas and fire detec-
tors. Gasmaster can also monitor flame detectors
as well as Crowcon'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.
1.2 About this manual
The manual is divided into sections which detail
procedures for installing, operating and maintain-
ing Gasmaster. Gasmaster is a safety system and
it is essential that all instructions are correctly
followed.
Details of the types of device that can be con-
nected to Gasmaster are shown in section 2,
along with typical connection diagrams. Section
3 provides instructions for day-to-day operation
of Gasmaster as well as detailed information on
system configuration.
Warning
Regular maintenance of any safety system is
essential, and failure to maintain the system
according to these instructions could result
in failures which could lead to harm to plant
and/or personnel or even death. Details of
the requirements for Gasmaster systems are
provided in section 4.
There are separate appendices for systems specifi-
cation and spare parts identification.
