The ‘improve don’t move’ climate in the housing market prompted our design for this range of battery powered standalone alarms for Yale. With more homeowners choosing to extend or improve their homes, the portable self-contained units are more flexible than a fully wired alarm system. The new range includes; a PIR motion sensor, a door hanger and a door contact, which offer superior protection and have a built-in siren and keypad. In addition, each alarm can be controlled with a remote keyfob or an additional siren may be added for increased alert.
