Gas Utility Controller
2.3
POWER [1]
A 110-120VAC Single Phase electrical supply should be supplied to the panel.
This should be externally fused at 3 Amps using a fused or circuit breaker.
2.4
GAS VALVE [2]
This outlet provides a 110-120VAC 3 amp signal to the solenoid valve. Please consult the
solenoid valve installation instructions for further information.
2.5
BMS OUT [3]
Terminal connections are available on the circuit board for connections to Building
Management systems. [NC – Normally Closed] [COM - Common] [NO – Normally Open].
These are volt free dry contact connections.
This is a relay that changes state in alarm or when gas is on/off and can be used in conjunction
with the 12VDC output and other external relays that affect other devices and controls such as
purge fans, audible alarms etc.
2.6
PRESSURE SENSOR [4]
The terminals marked [PRESSURE SENSOR] [+ - IN] are wired to the gas pressure transducer
which is screwed into the downstream port on the gas solenoid valve (see transducer
datasheet for more information.).
Operating Pressure = 0.17psi min - 1.45psi max
2.7
EM REMOTE [5]
These connections are linked out as a factory setting.
Remote emergency shut-off buttons should be volt free and wired to the Merlin panel using a
Plenum Security Cable. White, 18/2 (18AWG 2 Conductor), stranded, CMP or similar.
2.8
GAS DETECTOR [6]
These terminals are marked [+ -] and [
These can be wired to various Merlin gas detectors.
If no detector is being used, leave the terminal link in place.
For more information / multiple detector wiring, consult the gas detector manual.
