Hi all

Just trying to get our basic system so it won't alarm in a power cut, very annoying when trying to do electrical work on the house. I've already replaced the internal backup battery and left it 24hrs to charge but when I test it by removing mains power, the alarm sounds. I have 2 LEDs in the display, mains and day - both go out. The alarm is a C&K Securitech and unsure about the bell box make, although its hex shaped with 2 blue lenses at the bottom. Any ideas please guys? !

Fuse failure that covers the battery?

Battery fuse or duff battery.

Have you tested for DC Voltage on battery leads and battery terminals?

Was the 'original' duff old battery really foobared with lots of green stuff on the terminals, etc...

 

Just wondering if

 

a) Charger circuit knackered

 

and/or

 

b) Terminal wires very high resistance or rotted away under terminal plastics

 

and/or

 

c) Fuse gone as suggested

 

OP, you mention electrical work so we won't anger Arf with discussions of electrical safety; is there a voltage on the charger circuit and

if so what is it?

arf after recent events please don't take the p

Thanks everyone for the helpful replies. It was indeed the 1amp fuse for the battery. Replaced and tested OK. We had several short power cuts during bad weather last year, maybe these caused the issue?

Thanks again
