10.1	USE OF MXP LOOP FILTER BOARD

Some field problems have occurred with the MXP detector loop picking up interference from adjacent or nearby wiring, resulting in faults and possibly prealarms. The “MXP Loop Filter board” (part number PA1038) is now available and it can easily be fitted to an MXP in order to remove the interference and restore normal operation.

One or more of the following symptoms may be evident –

1.Intermittent “scan fail” faults.

2.Intermittent unexpected Prealarms.

3.The MXP diagnostic port “Total reply fail count” is much higher than expected (normally you should get less than 1 per hour).

4.The above problems occur in time with some external event e.g. lift motors running, radio transmitters operating etc.

Note that symptoms 1 – 3 above can also be caused by other factors e.g. the loop has too many devices connected or is too long. The MXP Loop Filter board will not help if this is the case.

10.2FITTING

Remove the loop wiring from the MXP. Fit the filter board in the loop wiring terminals of the MXP. Then fit the loop wiring to the filter board. Refer to Figure 10.1.
