Troubleshooting
Before investigating individual units for faults, it is very important to check that the system wiring
is fault free. Earth faults 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.

General
The Output Unit, part no 55000-849, provides a volt-free, double pole, change-over relay
output. It is supplied with a backbox for surface mounting and has an integral isolator as
standard.
Note: The Output Unit is not designed for outdoor use unless it is mounted in a suitable
weatheproof enclosure.
Installation
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 Output Unit 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.
