Gardtex 816 Sounder stuck on

[LeeS69]

Hi, I hope someone here can help me asap!

I have a Gardtec 816 which has been fine for years apart from the battery has gone - I just got back from holiday to find we have had a powercut and the alarm has sounded (no problem when its happened before)

This time the sounders have not/will not reset. The internal sound was on full tilt when I got in, alarm has unset no problem, everything else seems fine, I can use the system, set and unset but the bell + & - outputs are on 13v all the time and the internal sounder only has 2 wires so it can't be another connection somewhere. I think the - should normally be O/C

I've replaced the battery but the sounders trigger as soon as I reconnect (alarm panel still says unset with mastercode)

I can take the cover back off and do a factory reset, but I remember what a mare it was to program when we installed it.

I also cant for the life of me find the engineer code, but I do have the install manual.

I know there is a SAB SCB mode thing, coud it be that the setting has been lost, if thats the case I can reset the passwords and change the setting I guess?

Anyone got any suggestions please!?!

Try down powering mains and battery and powering up again. That often clears the microprocessor.

Thanks for the reply, I had tried that briefly but it didnt work

I actually just decided to give it another go and the default engie code worked

The system was set as SCB, i switched this to SAB and the negative went O/C, tried the internal sounder and it was fine, connected the external back up and did a system test and it all seems fine

I can only assume the system had lost this setting during the power outage, hopefully the new battery should help with that.

For info I got a 3.2ah battery from Screwfix for 13 quid, half the price of Maplin

Thanks again
