Caravan Alarm.

Caravan Alarm.
The siren on my Sargent 210 alarm was fairly quiet even when new, but now has become uselessly so. It’s quieter than a household radio.
It is less than 2years old and the battery shows full voltage; there was zero improvement when a car battery was connected in parallel. I’ve also noticed the PIR range has decreased.
Any ideas? GJK

I doubt that there's much you can do yourself to fix the problem. Phone Sargent Electrical Services Ltd service desk on 01482 678981 (during normal office hours) and have a bit of a moan about their product!
