Fan Switch Integration
There is the facility to connect a Fan Switch.
A fan switch (Merlin FS1 or FS2 - sold separately) provides the facility to turn on fan(s) when the
2000S panel is switched on and removes power to fan(s) when the switched off.
There is a switch located on the circuit board labelled [EM SEL].
OFF
Instructs the system to shut down fan(s) and gas supply upon
activation of emergency shut off button(s). (Default)
ON
Instructs the system to leave the fans on and shut off the gas supply
only upon activation of emergency shut off button(s).
Note: This option is not available if a Fan Switch is not installed.
Fire Panel Integration
The Merlin 2000S 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].
