Hi,
The internal alarm has gone off. Not sure why, because an electrician had disabled it or so I thought (it's a really old alarm and I want it replaced eventually). I think he must have just disconnected the main alarm outside.

A lot of the PIRs have been disconnected during decorating.

I disconnected another PIR today and no problem at all. That was hours ago.

Now the internal alarm (fortunately not loud so the neighbours could here it) has gone off.

I don't know the code. What can I do, please?

Disconnect it

Should I get an electrician to do it?
