Novice decommissioning Honeywell alarm

CaRuthers · 29 Dec 2018

Hi - looking to decommission an old Honeywell alarm - not sure how to disconnect mains power to the board?

If I remove the two black wires capped off in white from the upper left of the circuit board will that do it?
Thanks

I’ve already disconnected the red wire from the rechargeable battery. Control panel is still on though

You need to disconnect the 230v mains supply so be careful. Pull the fuse. However be warned that when the the panel is de-powered the external sounder will/should activate for 15-20 minutes using its own internal battery.

You need to find the source of the twin and earth cable (grey) and isolate there, normally an unswitched spur and then the panel is totally isolated

Ok thanks- some more photos for you - I can see the wire that connects to the mains - seem to also have a fuse too.

Remove the fuse from the fuse spur ....

That sets the alarm off. Someone suggested the engineer code would stop that from happening? Otherwise do I need to remove another battery from the sounder as well?

Here’s the internal sounder. Think it’s the top one.

You have two panels? First photo the 230v is wired in twin & earth and the second is wired in flex.

Ignore the first photo - wrong one uploaded now updated. Just one panel.

the sounder will sound for 15-20mins, need ladders to stop/remove battery. disconnect all the rest as your going, remove the fuse from the unswitched spur you're pointing at first to remove panel supply

It’s only an internal sounder - no external . Just the boxes in this photo.
Do you think the battery will be easy to remove once I get the cover off?

Some success - removed one sounder too box, middle box has a battery which I guess I should disconnect the try pulling out the fuse to kill the motherboard and panel? Any ideas what the bottom box is? Telephone connection perhaps?

In engineer mode the tampers should be disabled, so you could remove the cover from your sounder and have a look. FWIW the battery in mine was easily removed, but it looks nothing like any of the three boxes in your pic. The top one looks similar to my internal speaker/horn tho.

Can’t get into engineer mode as we don’t have the original user code so can’t get to the menu to try some of the default engineer code. Also tried a selection of default user codes too - doesn’t do it either. Doesn’t appear to be a tamper on the sounders- expect when I relive the battery the alarm may go until I remove the fuse?
