Aico Ei100L Ionisation Smoke Alarm with light battery powered only (no mains). The bright light turns on when the alarm sounds.

The smoke alarm is ideal for halls and stairs where fire causes power black-outs and darkness and smoke cause panic especially with children. The ultra bright light automatically illuminates your escape route when the alarm sounds.

Product Features:

• Ionisation sensor - responds to all fires and is especially responsive to fast flaming fires.
• Loud alarm - 85 decibels at 3 metres.
• Quick easy installation, no wiring.
• Test button simulates smoke.
• Batteries included.
• Warming 'bleep' when battery needs replacement.

Ionisation type sensors are particularly sensitive to the almost invisible smoke produced by fast flaming fires. This makes them more liable to false alarm due to cooking fumes if sited in a hallway close to a kitchen. Ionisation detectors are recommended in living rooms and dining rooms where they are less vulnerable to false alarm caused by dense tobacco smoke, excessive dust and insect ingress.
