Where should I position the alarm?

Rated 5 out of 5 by from Trust "First Alert" Purchased this unit to replace my first "First Alert" device which has operated for many years with no problems .It actually told me it had reached the end of its life and required replacing .Hence the new purchase. This unit is smaller than the original and can be fitted to the wall with 2 screws but is small enough to be taken on holiday with you if you are going in a caravan or hotel with a gas appliance in the room. Very loud alarm.
