Hi All
Ive just reconfigured my NX-4 and i have a pesky service light that i just can’t seem to clear. It means that i have to enter user codes twice, once to disarm and another to clear the service alarm (im guessing)

When i ‘*2’ i Zone 1 light comes on. I then go into Zone 1, then Zone 6 is lit. Which = ‘Expander Box Tamper’ according to my manual.

But i just cant seem to track down the cause of the service alarm.

I should add that my PIR sensor on Zone 4 appears to be not working correctly. It works but only when i wave my hand about 50cm away.

Can any one give me a clue where to start?
