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.
