Installation & Operation Manual
Switch Settings
Building Management System Integration
There is a DIP-switch located on the circuit board labelled [BMS SEL].
The panel can be integrated with a BMS to make or break a circuit when the gas is either on or off,
(valve open or valve closed). This will tell the BMS whether or not power is being sent to the solenoid
valve.
OFF
Signals the BMS when gas is on or gas is off. (Default)
ON
Signals the BMS on a fault, i.e. high gas levels detected, emergency shut-off activated, etc.
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].
Instructs the system to shut down fan(s) and gas supply upon activation of emergency shut
OFF
off button(s). (Default)
Instructs the system to leave the fans on and shut off the gas supply only upon activation of
ON
emergency shut off button(s).
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].
Gas Fill Time and Prove Time
FILL TIME: Amount of time the gas valve opens to fill the gas line on power up or reset.
PROVE TIME: Amount of time the system tests the gas line for leaks on power up or reset.
There are two switches located on the circuit board labelled [FILL TIME] and [PROVE TIME].
