Aico Ei660iRF Radiolink Optical and Heat Sensor Alarm with 10 year Lithium Battery

The Aico Ei660iRF is a battery-powered multi-sensor fire alarm designed for domestic fire protection, combining both optical smoke detection and heat sensing for faster and more reliable fire response across a wide range of fire types.

It is powered by a sealed 10-year lithium battery, meaning no battery replacements are required for the full life of the unit, making it low-maintenance and ideal for residential installations such as hallways, landings, living rooms, bedrooms, and loft spaces.

The Ei660iRF features RadioLINK+ wireless interconnection, allowing it to communicate with other compatible Aico alarms so that if one unit detects danger, all linked alarms will sound simultaneously for whole-property coverage.

It also includes AudioLINK+ technology, which enables data extraction via a smartphone app, providing information on alarm activations, sensor status, and maintenance history—useful for installers and landlords managing compliance and servicing.
