A Dummy Bellbox External Wall Siren with matching looks of the "real" Elmdene device. Provides a useful deterrent to the back of the house where the real device is normally fitted at the front. 

Can also be used with systems already fitted with autodiallers offering the same deterrent but without the requirement for an actual audible alarm.

Saves time! Install this dummy box and save the hassle and cost of wiring from your control panel through the house to the working siren.
