Gardtec 800 Series

[tcasplett]

I nicked one of our house alarm cables yesterday which set the alarm off. It's a Gardtec 800 series alarm.

I removed the fuse to stop the alarm sounding. The panel by the front door, where I input the code to set the alarm, is off.

Should we disconnect the battery too?

What should I do with the nicked cable?

We want to turn it off completely. Any advice?

It shouldnt have stopped the alarm turning the power off, this suggests that your battery is u/s. The siren / bell would normally have it's own battery and will continue to sound even when the wires to the panel are cut, assuming that it doesnt have it's own battery or it's battery is also u/s then leaving the alarm powered down is all you need to do. Take into consideration any insurance aspects this may have.

Thank you for your reply.
Does u/s mean depleted? We do have a battery so presuming that it is depleted.

Is it a concern to have a nick in the cable? We have put electrical tape around it.

u/s = unserviceable so yes, depleted if you like

It depends on what cable eg if it's the mains supply going in or one of the alarm cables etc. If it's the mains then make it safe, isolate the supply, if it's the alarm cables, tape it up, disconnect the alarm battery and mains supply, all good.

We have put electrical tape around it.

The external bell box/siren/sounder has its own battery..

The battery in the panel is there to keep the alarm running during mains power failure..

The battery in the external sounder is there to keep the alarm sounding if someone try's to cut the cables and stop the alarm working..

Basically if the external sounder receives an alarm trigger signal from the panel.. OR sees that the tamper-loop has been broken, (someone has cut all or part of a cable).. OR no longer sees a charge voltage to keep its own battery working then it should sound the external alarm...

If you don't have access to a suitable continuity test meter.. and battery tester..
Then it may be quicker and cheaper to just get an alarm competent person round to check it over..

Probably needs a new battery and quick cable repair?

(If your alarm used to go off during power-cuts then the main panel battery is knackered..
which typically have a 5year manufactures recommended lifespan for the average 12v alarm battery).

The OP said they wanted to disable it completely.
