Help with alarm

[sparkyb]

I installed an alarm system about 4 years ago and everything was fine until about a month ago when the client heard a chirping noise coming from the external bell box, I went around and checked the battery in the panel and it was ok so I set the alarm and it set properly and seemed to be working fine. He called me today again and told me that the external bell was again chirping like a bird. Any ideas what could be wrong.

Thank you

How about battery in bell box?

 

[sparkyb]

How often should it need replaced?

 

[mayfair]

would say your about there , most batterys should be checked on annual inspection.

 

[sparkyb]

what voltage should i be getting on external bell battery and also panel bell too?
what other tests should be done on annual inspection.

thank you for your help

if the bell is chirping as opposed to ringing could be the bell/bell batt,better off just replacing the bell.if no tamper on panel showing looks like the bell,have you checked for water in the bell

wasn't there a thread a few months ago about chirping bells. something to do with the extremely low temperatures . forget what it was causing, could be a poor batt. in the panel dragging the 13.6volt supply down.

 

[alarm man]

your right tel i remember it,tho i dont remember the make of bell..

 

[telectrix]

could be the nicad in the bell box was too cold, so that might be a place to start. take a new bell box batt. and a new panel batt. for starters.

 

[alarm man]

just replace the bell,cheap enough

that's defeatist. i would measure the hold off voltage 1st at the panel and then at the sounder .

id call it experience and customer service..it volts was low it would ring and cause tamp,and he says he already been to site and all appears ok
