The Emergency shut off button(s) will cut off the gas supply when activated.
To reinstate the system, the Emergency shut off button(s) will need to be reset and the panel
restarted.

BUILDING MANAGEMENT SYSTEM INTERGRATION
The Merlin 1000Si can be integrated with a BMS to make or break a circuit on gas on/gas off,
(valve open or valve closed). This will tell the BMS whether or not power is being sent to the
solenoid.
There is a dip-switch located on the inside facia of the Merlin 1000Si labelled [BMS SELECTION].
This is factory set in the 'off' position which signals the BMS on gas on/gas off.
When switched to the 'on' position, the 1000Si will only signal the BMS on a fault, i.e. CO2 high
level detected, gas detected, EM Stop pressed, etc.
3.5
FIRE ALARM INTERGRATION
The Merlin 1000Si can be integrated with a fire alarm to shut the gas supply automatically in the
event of a fire. The volt free fire alarm signal can be wired in series with any remote emergency
shut off buttons.
