Merlin 1000Si
Gas Utility Controller

Using the Emergency Shut Off

3.3
The Emergency shut off button is located on the front of the panel. There is also a facility for remote
shut off buttons to be wired in series.
The Emergency shut off button(s) will cut off the gas supply when activated.
To reinstate the system, the Emergency shut off button(s) will need to be reset and the panel restarted.
BMS Integration
3.4
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.
Fire Alarm Integration
3.5
The Merlin 1000Si 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'.
Fan Switch Integration
3.6
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 1000Si is in
the on position and turn the power off to the fan(s) when the key switch on the Merlin 1000Si is in the off
position.
There is a dip-switch located inside the facia of the Merlin 1000Si 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.
Auto Reset
3.7
The Merlin 1000Si has a built-in auto reset feature. There is a dip-switch located on the inside facia of
the Merlin 1000Si labelled "Auto Reset". This is factory set in the 'off' position. When the power is
restored after the power cut, the panel has to be restarted manually. On installation, this can be
switched to the 'on' position if required. This will instruct the system to restart automatically when power
is restored after the power cut.
