Aico Ei660i Multi-Sensor Fire Alarm

The Aico Ei660i is a battery-powered multi-sensor fire alarm designed for domestic fire detection, combining both optical smoke sensing and heat sensing to improve response speed and reduce false alarms.

It is part of Aico’s 600 Series and uses a sealed 10-year lithium battery, meaning the unit is maintenance-free for its full lifespan with no battery changes required. The Ei660i is designed as a standalone alarm (unlike the RF version, it does not interlink wirelessly), making it suitable for individual room protection or simpler installations
