I've just moved to a house where an optima XM 4 zone alarm is installed - probably installed

at least 9 years ago. The problem I have is when the electricty supply goes off, so does

the outside bell - does this indicate the battery needs changing - is it in the alarm panel or bell box and if so how do I go about changing it and what type of battery is usually used.

Many Thanks

Yes the battery has probably failed.

It would most likely need a 12-volt 2.8/3ah SLA replacement battery, HOWEVER, if the system is around 9 years old and the battery has failed it should be checked by an engineer as it likely has not been recently serviced and it may have been damaged. Additionally an engineer can assess whether or not the existing battery capacity is suitable for the size and nature of your installation.

Post your location and someone here may be able to assist or check for an installer at www.ssaib.org/search.html or www.nsi.org

Or better still have a look HERE for an engineer
