Electrician needed help!

[Susannaj]

Hi

Our communal smoke detector which is mains wired has gone bonkers. The battery support has run out so it is beeping all the time. Thought I was being useless not being able to get the over off, but no it simply will not shift and yes even my builder could not manage it. So prob need a new alarm and someone who knows what they are doing with electricity to sort this one. Please message if you know anyone good who is qualified.

Thank you!
