Random alarm triggers

[Adrian80]

Hi all,
I have had a couple of random triggers of my burglar alarm. It's a g4 accenta mini.

It doesn't log a fault code, and the date and time on the key pad needs resetting.

The fault seems to coincide with a resetting of the cooker clock, the funny thing is the cooker hasn't tripped anything rcds or mcbs, alarm is on a separate beaker and that hasn't tripped either.

I put the alarm in 2008 and has been fine no problems whatsoever

The battery backup seems to work, when I switch the alarm mcb off the keypad is still lit so looks like its not completely dead.

Checked the cable best I can and all seems fine. ?

Any suggestions I have a Multi meter, and can just about use it.

Cheers A

Power cut battery faulty ? Should be replaced every 5 years..

It's a funny one.
I wouldn't say we had a power cut As its only the cooker clock, microwave is ok,

Can I meter the battery out, check the voltage any idea of what sort of volate
I would get

Only with a battery tester either a act or yuasa battery tester it can have 13v but no ah ...if it's over 5 years old replace for the sake of a £10
