My C & K alarm is acting up. On two sensors the alarm picks up movement and omitts an annoying bleep, It's just started out of the blue, though I'm currently building a small extension, not sure if it has anything to do with it. The panel looks fine and i've tried the reset code. Any advice... ta

Hi
I have the exact same alarm & the exact same problem.
Did you sort it out in the end?
It's driving me nuts!!!

You've turned on the 'chime' facility, or, it's a smoke detector giving a low battery warning
