Troubleshooting
Before investigating individual units for faults, it is very important to check that the system wiring
is fault free. Earth fault on a data loop or any ancillary zone wiring may cause communication
errors.
Many fault conditions are the result of simple wiring errors. Check all connections to the unit
and make sure that the correct value resistors are fi tted where necessary.
Fault fi nding

Locally Powered Zone Monitor
Installation Guide
General
The Locally Powered Zone Monitor, part no 55000-864, is supplied with a backbox for surface
mounting. It has an integral isolator as standard.
Note: The Locally Powered Zone Monitor is not designed for outdoor use unless it is mounted in
a suitable weatherproof enclosure.
Surface Mounting
1. Mount the backbox as required and install all cables for termination. Ensure that earth
continuity is maintained.
2. Remove the cover plate (if secured) from the Zone Monitor assembly by inserting the blade
of a terminal screwdriver into each of the four securing clips in turn, gently prising the outer
edge of the cover plate over the clips underneath. DO NOT USE EXCESSIVE FORCE.
3. Terminate all cables.
4. Gently push the completed assembly towards the backbox until the mounting holes are
aligned and secure with the two mounting screws provided. DO NOT OVERTIGHTEN.
5. Set the address of the unit as shown on page 3.
6. Finally, when commissioning is complete, fi t the cover plate by placing it in position,
observing the correct orientation (LEDs on the PCB must be aligned with viewing holes).
Apply pressure to the cover plate until all four clips are holding it in position.
