Can anyone tell me what this is?

Hi, I was wondering if anyone could tell me what this is? Its beeping as if it's a fire alarm with low battery and we have no idea how to stop it.
Thanks.

It's just an internal speaker disconnect the blue cables but it must be beeping for a reason looks to be part of an intruder alarm

Have a look at your alarm panel and see what fault is showing, once that is resolved it should stop.
If you disconnect it you may find there is an internal speaker in the panel still sounding.

If it happens again use the Philip Schofield method
