Emergency Hold Input
This input connects to an Emergency Hold Switch or call point. The line needs a 2k2
end of line resistor, and a 470R resistor across the line to trigger it.
If this input is operated during a second stage alarm, during the release count down,
it will reset the counter to it`s starting value, and hold it there, until the Hold device is
reset. This prevents the panel from releasing the gas. When the hold device is reset,
the panel resumes counting, and will release the gas at the end of the countdown.
There is a RED “ACTIVE “ LED which lights when the input has been operated, and
a yellow fault LED that lights in the event of an O/C or S/C line fault.
If this input is disabled, any hold devices connected to the line will not be able to stop
the gas release.
Emergency Abort Input
This input connects to an Emergency Abort Switch or call point. The line needs a 2k2
end of line resistor, and a 470R resistor across the line to trigger it.
If this input is operated during a second stage alarm, during the release count down,
it will freeze the counter. The counter WILL NOT restart if the abort is released. The
panel needs to be reset to exit this condition.
There is a RED “ACTIVE “ LED which lights when the input has been operated, and
a yellow fault LED that lights in the event of an O/C or S/C line fault.
If this input is disabled, any Abort devices connected to the line will not be able to
stop the gas release.
Auto/Manual Input
This input connects to an Emergency Abort Switch or call point. The line needs a 2k2
end of line resistor, and a 470R resistor across the line to trigger it.
When the panel is in automatic mode, and this input is operated the panel changes to
manual mode. When the input is released, the panel reverts to Automatic Mode. If
the panel is already in manual mode, this input will have no effect.
There is a RED “ACTIVE “ LED which lights when the input has been operated, and
a yellow fault LED that lights in the event of an O/C or S/C line fault.
If this input is disabled, the panel facia auto/manual toggle button will still work.
Pressure Switch Input
This input connects to an Emergency Abort Switch or call point. The line needs a 2k2
end of line resistor, and a 470R resistor across the line to trigger it.
This is an ancillary bottle connection. If the bottle has only a pressure switch to
indicate the release of the gas, it should be connected to the GAS FIRED input. If the
bottle has more than one input, connect the primary indication to GAS FIRED, and
the secondary indication can be connected to the pressure switch input.
There is a RED “ACTIVE “ LED which lights when the input has been operated, and
a yellow fault LED that lights in the event of an O/C or S/C line fault.
Disabling this input prevents it from showing as active on the panel display.
