WHAT G.I.S. UNITS DO
The 230V G.I.S. monitors either Air Pressure Differential
Sensors mounted in the extraction and air supply ductwork
and/or Fan Power Sensors. In the event of fan failure or significant
air flow reduction (as calibrated by an installation engineer),
the sensors will actuate the GIS, which in turn closes the
gas solenoid and cuts off the gas supply to the kitchen appliances.
ADVANTAGES OF
G.I.S.
Smart and compact design
Complies with new CIS
23 (revised)
Easy to install: clear and simple instructions with
diagrams.
Easy to Operate: one button operation with clear indicators.
All features explained fully on the fascia plate.
Market-Leading Features:
- Anti “Back
Pressure” feature on all models
- Option of “Fail
Safe” double sensor warning model
(M-G03) provides the operator with “peace
of mind” and a means to avoid
system actuation through a faulty or failed
sensor. Provides clear warning that a single
sensor has failed. The system only shuts
off the gas supply when both sensors actuate.
- Option of "Built-In"
Emergency Stop is available on units
with model numbers ending in "R"

Multiple G.I.S. units can be wired together to operate more
than two fans:
New GIS series:
2x options of GIS systems – with Single or Double Sensor
warning
New GIS series: can
be supplied with a built-in Emergency Stop
Existing/old style GIS Series
(M-G01 N) with no override can be supplied
Back pressure sensitive - 10 second activation
LED lamps and high quality components
Easy to clean and protected to IP54
Neat and compact – easy to install –
easy access for wiring
Manufactured in the U.K. with a one year guarantee
SYSTEM REQUIREMENTS
It is the Customer's responsibility to determine
the suitability of the GIS system for the application.
GIS unit, model of your choice
Air Differential Switch or Fan Power Sensor
Electrically Operated normally closed, Gas safety shut-off
Solenoid valve
Remote Emergency Shut-Off Switch or choose a GIS unit with
built-in shut-off switch (though installers may choose to
still install a remote shut-off switch, if preferred)
