Merlin 1000S
Gas Utility Controller
EM STOP
If an emergency shut off button (either remote or on the panel) is pressed, the LED will
illuminate and the gas will be shut off. The EM Stop button must be re-set before restarting
the system.
OFF = OK
AMBER = EM Stop button pressed
GAS DETECTED
Under normal working conditions this LED is off.
If the external Merlin detector connected detects gas this will illuminate and the gas valve
will shut off.
OFF = OK
RED = Gas detected.
CO2 HIGH
Under normal working conditions this LED is off.
If the concentration of CO
LED will illuminate and the gas valve will shut off.
OFF = OK
RED = the concentration of CO

Emergency Shut Off Use

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.

Building Management System (BMS) Integration

The Merlin 1000S 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 1000S
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 1000S will only signal the
BMS on a fault, i.e. CO2 high level detected, gas detected, EM Stop
pressed, etc.

Fire Alarm Integration

The Merlin 1000S can be integrated with a fire alarm to shut 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 stop buttons installed, wire this directly to the terminal
marked [EM REMOTE].
