one alarm sounder randomly going off

[scotsgraeme]

Hi folks
I've got a texecom premier elite 24 with a pair of pyronix deltabell plus sounders. Today one of them (the rear which has longest cable run from panel) started to go off, no sound from the front one, or any indication on the alarm panel of tamper, or any fault.

I expect this is related to the MASSIVE downpour and lightning we've had for past hour or so.

Is there anything I can do to shut it up? Is there an easy way to cut power to the sounder in such a way it will just run flat and I can look at that when it's not torrential?

Should I be replacing the battery in the sounder? It's 3.5 years old, and if so, where can I get a battery?

Any advice is greatly appreciated. Hoping I can sort it out myself without an expensive weekend alarm engineer callout

Sounds like the tamper switch is open , if so should stop after 15 mins ...

surely the sounder should be telling the panel that tamper is open? When it's dry I think I'll need to get up a ladder and take a look i guess
