INSTALLATION INSTRUCTIONS
The M2AP01 fire detection Alarm Panel can be used on two distinct types of installation:
MusterWire LHD Installations
In MusterWire LHD (Linear Heat Detection) installations; the Alarm Panel electrically monitors for fire using MusterWire
LHD (heat detection wire) and automatically activates the discharge of the system as well as providing alarm,
monitoring and shutdown functions.
This system works in conjunction with the Muster
II Cylinder Valve (M2VA01) with integrated pressure transducer and
release solenoid. The system must be connected to MusterWire LHD (heat detection wire) and an EOL Resistor Plug
(M2RP01) to function. Alarm, Fault and Shutdown relays are used optionally as required.
LOP Installations
In LOP (Loss of Pressure) installations; the system is activated automatically and independently of the Alarm Panel
which only provides alarm, monitoring and shutdown functions. LOP installations work in conjunction with the Pressure
Transducer (M2TA02) to detect a fire condition. The detection circuit is not used in this system. Alarm, Fault and
Shutdown relays are used optionally as required.
SETUP
Two banks of five DIP switches each are used to set up the operating parameters of the Alarm Panel.
LEFT BANK
Relay Contacts:
DIP switches 1, 2 and 3 control the contact types of the SHUTDOWN, ALARM and FAULT relay outputs.
The options are contacts normally open (N/O) and contacts normally closed (N/C). The factory setting is N/O as this is
the most common application. However it is recommend where possible to use the N/C setting as this allows immediate
indication of breaks (open circuits) in the external wiring to these circuits.
LOP / LHD (MusterWire): Dip switch 4 controls the type of fire detection system being installed. Select LOP for an
automatic Loss Of Pressure system. Select LHD for an electrical monitoring system using MusterWire LHD.
Isolated / Active: Dip switch 5 is used to ISOLATE the Alarm Panel. In ISOLATED mode the Alarm Panel releases any
relay outputs and will not go into FIRE mode or discharge the system. When changing from ISOLATED to ACTIVE mode
any fire that is detected within the first 4 seconds will be treated as a fault and not a fire. Furthermore, in ISOLATED
mode the Pressure, Fault and Fire indicators on the Alarm Panel will reflect the status of those circuits thus allowing a
technician to safely fault-find without any risk of the system being discharged.
This setting is disabled for LOP systems.
