I recently found that the keypad on my Optima XM alarm was not working. I have changed the battery and managed to get it working. After doing this I decided to do a walk test to confirm that everything was working. Everything is working except zone 4 which has a PIR on the landing and a PIR in the kitchen. The PIR's both flash when I walk past but do not trigger the alarm.

All connections appear to be OK

The system was installed by builder 20 years ago and has worked well throughout (2 new batteries)

Is it likely to be a faulty PIR?

How do I find out which one?

Thanks

You could link the alarm sensor contacts manually to check there's no cable fault

 

I assume it sets otherwise

has it ever worked?

Thanks, will these be the red/yellow wires at the sensor?

I assume that I leave the other 4 wires connected to the sensor?

Yes it has worked for years with out any problems

James, I assume that it has always worked since they flashed has I walked past them and the system armed etc.

I've not done a walk through test until today.

so zone 4 used to indicate. When did you last walk test it succesfully

Ok id say they have never worked then.

All the zones are being used.

The landing sensor is probably least important.

I'm not confident about messing with the spaghetti in the box, could I wire through at the sensor?

I have disconnected the landing sensor in the box and the kitchen now works.

 

I now have the following

 

Zone 1 - Front door contact sensor

Zone 2 - PIR

Zone 3 - PIR

Zone 4 - PIR

Zone 5 - 3 doors with contact sensors

Zone 6 - PIR

Unused PIR on landing

 

Do I have any options for landing PIR?

yes wire it in correctly. and use a latching sensor.
