PSA HomeGuard HG140AC 240V Photoelectric Smoke Alarm, 9V Battery Backup (6 Pack)

This pack contains six PSA HomeGuard HG140AC photoelectric smoke alarms. Each alarm runs on 240V mains with a replaceable 9V backup battery, and six is enough to cover the bedrooms, hallways and living areas of a typical house in one job. Each alarm has a wide 140mm base designed for replacement work, as it covers screw holes and paint marks left behind by older, smaller alarms.

The six units can be wired together so that when one detects smoke, they all sound. The HG140AC supports up to 48 interconnected alarms over a maximum of 150m, so larger homes can be covered by adding more units.
