Aico Ionisation Smoke Alarm. 230v

The Aico Ei151TL Ionisation Smoke Alarm runs on 230V AC mains power, and has built in tamper proof Lithium cells that act as a battery back-up in the event of mains failure. These rechargeable Lithium cells are designed to have a ten-year life and outlast the life of the smoke alarm itself, whilst providing up to six months of smoke alarm operation without mains power.

The alarm gives a fire warning when adequate smoke enters the alarm.

The alarm has other advanced features such as built in circuitry to aid suppression of voltage transients and RF interference to further reduce the chances of false alarms under such conditions.
