WIRING

Wiring of the Muster fire detection system and associated peripherals is simple with a maximum of five circuits, each
requiring only a single pair of wires. Wires from the Alarm Panel are pre-paired, colour coded and marked. Only the
pressure transducer circuit is polarised, the remaining four circuits having no polarity. Wiring for all circuits is done with
the two core silicone cable provided and joints are made with the two way splice kits supplied. The splice kits are IP68
rated, however it is important that exposed splices are protected with the red glue-lined heat shrink supplied.
Care must be taken when using the heat shrink over the
MusterWire LHD as excessive heat could activate the wire.
Apply heat only to the heat shrink and not directly to the wire
and only use a suitable heat gun. Do not use a lighter or flame.
PRESSURE TRANSDUCER CIRCUIT: (Mandatory for both MusterWire LHD and LOP systems)
This circuit connects the Alarm Panel to the M2TA02 pressure transducer for LOP systems and to the Cylinder Valve
(M2VA01) for MusterWire LHD systems. In MusterWire LHD installations this circuit performs a dual function of
monitoring pressure and activating the release solenoid. This circuit is polarity sensitive. Use the two core silicone cable
with blue and brown cores as provided to assist in maintaining the correct polarity when wiring. Note that should this
circuit be wired reverse polarity no damage will be done and the Alarm Panel will indicate a SYSTEM FAULT.

MUSTERWIRE DETECTOR CIRCUIT: (Mandatory for MusterWire LHD systems. Not used on LOP systems)
This circuit connects the Alarm Panel to the MusterWire LHD (Linear Heat Detector wire) and to any manual actuation
stations required. All devices must be wired in series, with a Resistor Plug (M2RP01) used to terminate the very end of
the line. If the Resistor Plug (M2RP01) termination is not present or if the circuit is broken at any point (open circuit) the
Alarm Panel will indicate a SYSTEM FAULT. The MusterWire LHD and the manual remote actuators can be wired in any
order and any number of manual remote actuators can be used.
