House alarm sounding when the electric power is interupted

I have posted this thread here because i cannot find anywhere else.:confused:

Anyway i have a Optima plus 2 House alarm which goes off at the sounder in the outside box when the Electric power is turned off.Nothing happens on the control panel inside (No display and quite)
I have installed a new 12v battery inside the panel and it does not seem to have made any difference. When the power is re-instated it goes off again but i am able to disable the sounder as the panel is now lit.
Please help as i do not want to have a new alarm system. I am capable of repairs but need a little help or advice from a specialist.
Thanks you

What it should do is go into standby mode not alarm
Powering from the back up battery in the control panel. This enables you to interupt the power supply to work on any electrics in the house without alarm activation

I'm sure my Optima does exactly the same. I thought it was an anti-tamper device. When we had a local powercut recently mine went off, but so did quite a few others in the area.

How often do you loose power to the unit to make it a problem.

Just spoken to an alarm specialist and apparently it is the charge circuit within the control panel that is not charging the 12v back up battery. This prevents the battery from coping with the power drain when there is no mains voltage. The alarm should not sound outside when the power is cut only within the control panel a faint beeping should be heared to let you know it is on standby power.
Hope this helps anybody else.:)
