Hi there, in July 2008 I had an intermittent problem with my 9448+ where the tamper alarm would trigger (with the alarm set or not set).

As I was going away on holiday I did the following:

1) replaced the battery with a Yucel one from my local alarm supplier

2) linked the global tamper in the panel (i.e. linked the two A/T terminals)

3) linked the 0v and TR terminals in the panel (to eliminate the bellbox)

4) and I think I linked the 0v and TR terminals in the external sounder as well (a Westech Armourflash)

Anyway, all has been fine over the last year until about 2 am this morning (alarm not set) the alarm triggered with the tamper light on again (internal sounder, I did not notice if the external one was sounding)

It will reset OK and has not gone off since the early hours. As I am soon to go on holiday (it always happens before going away!!) I checked the panel tamper switch (engineer access walk test) and it seems OK.

Any ideas what could be causing this

thanks

PS I fitted the alarm system about 10 years ago and it has been fine, apart from this problem!

Apart from a faulty panel the most likely cause is the battery again - try getting a reolacement & see if that works .

PS disconnecting your external bell tamper means that if anyone interferes with it there will be no alarm activation - not good.

Bells (sounders in modern parlence) have a tamper zone for a reason.

When you linked global & bell tamper - did you leave the existing wires in place? If so you could have wiring fault.

Thanks fpr the replies, yes I know bypassing the external sounder tamper is not ideal!

I have replaced the battery for a new Yuasa one and will see what happens.

Yes I did leave the existing wires in place when I linked out the tampers, thinking if they are shorted together it should not matter what the wiring is doing. Is it best to disconnect the other wires?

Is it best to disconnect the other wires?

Yes, because a tamper fault can be generated by a short cct between say a zone wire & the tamper wire you have left in place. (the idea is to make by passing your alarm more difficult to intruders).

Ideally of course you would prove faulty cable & rewire it
