Unless YouTube/Google/ manufacturers website or helpdesk says otherwise, I'd say change both batteries for new Duracells, hoover out, ensure paper gasket is in correctly, replace and test. If beep doesn't stop I'd guess these babies are done and you need a couple of new alarms fitted. They seem to be a bit niche, so maybe get an alarm company to do it rather than have a go yourself or use a standard electrician because if it goes wrong, that bleep is a prelude to madness!Just 2 one downstairs one upstairs.
