What is expected battery life duration?

Not had mine long enough yet for the battery to go

can it be used on a caravan wall?

Preferably on the ceiling. Not too close to a direct heat source

Ok this is a daft question so please be kind...having difficulty getting the back of the unit back on.Does the security arm lay flat or not .?

Hiya, push the arm down into the compartment then put the battery in. Hope this was helpful

I'm looking for an alarm that will go off with cigarette smoke is does this pick it up?

I do not smoke, so I do not know the answer.
