Gas Interlock System

BMS integration

The Merlin 1500S 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 100-240VAC is being sent to the
solenoid.
There is a dip-switch located on the inside facia of the Merlin 1500S 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 1500S will only signal the BMS on a gas detected.

Fire alarm integration

The Merlin 1500S 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 is no remote emergency stop buttons installed wire this directly to the terminal marked
'EM REMOTE'.
3.7

Fan Switch Integration

There is the facility to connect a Fan Switch (FS1 or FS2 sold separately).
The Fan Switch provides the facility to turn on the fan(s) when the key switch on the Merlin 1500S
is in the on position and turn the power off to the fan(s) when the key switch on the Merlin 1500S
is in the off position.
There is a dip-switch located inside the facia of the Merlin 1500S labelled EM Selection.
This is factory set in the 'off' position which instructs the system to shut down the fan(s) and gas
supply on activation of the Emergency shut off button(s). On installation, this can be switched
to the 'on' position if required. This will instruct the system to leave the fans on and only shut off
the gas supply on activation of the Emergency shut off button(s). Note: This option is not
available if Fan Switch is not installed.
