Fire Panel Integration
The Merlin 1000S+ can be integrated with a fire alarm to close 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.
If there are no remote emergency shut off buttons being installed, wire this directly to the
terminal marked [EM REMOTE].
