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 fitted where necessary.

XP95 Output Unit
Installation Guide
General
The XP95 Output Unit, part no 55000-819, is supplied with a backbox for surface mounting. It is also
available without a backbox for flush fitting — part no 55000-817. For flush fitting the installer will need to
provide a suitable metal box with fixing centres of 120.6mm (UK standard 2-gang accessory box).
Note: The XP95 Output Unit 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 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 back box 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, fit 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.
Flush Mounting
1. Secure a suitable metal back box (30mm minimum depth) in position and install all cables for
termination. Ensure that earth continuity is maintained.
2. Follow steps 2 to 6 as above.
