Aico Ei146e Mains Powered Interlinked Optical Smoke Alarm

Comprehensive fire safety for every room in your home

The Aico Ei146e brings reliable whole-home protection through intelligent interconnected detection. When one alarm is triggered, all connected alarms sound simultaneously, offering comprehensive coverage throughout the premises. This means if a fire starts on one level and you're in another part of your home, there's a chance you may not hear the alarm going off—but with an interconnected system like this, the alarm will sound in multiple locations when one is triggered.

Proven optical detection technology

The Ei146e features an optical sensor chamber—the modern standard for residential smoke detection. Optical smoke alarms are less likely than ionisation models to produce false alarms, and are quicker to detect slow-smouldering fires that produce a lot of smoke. British Standard BS 5839-6 now recommends optical or multi-sensor alarms instead of ionisation technology. This makes the Ei146e suitable for hallways, living rooms, bedrooms, dining rooms, and landing areas where slow-burning fires from soft furnishings are a concern.

Flexible interconnection options

Mains power without losing protection during outages. The mains powered design eliminates worries about dead batteries, while built-in backups maintain protection during power failures—combining the best of both power sources. Choose between hardwired or wireless interconnection depending on your home layout and installation preferences. Both methods ensure all alarms communicate instantly when smoke is detected.

Quick and simple installation

The easi-fit base makes mounting straightforward, reducing installation complexity compared to some competing systems. Mains-powered, interconnected smoke alarms can be installed by an electrician or retrofitted by connecting them to the nearest light fixture. Once installed, the large capacity sensor chamber requires minimal maintenance while delivering consistent, reliable detection.

Why choose mains-powered interconnected alarms?

Interlinked alarms are now a legal requirement in certain UK homes, especially new builds and rental properties. This interconnected system is ideal for larger properties or multi-storey buildings, providing immediate alert throughout the premises and maximising evacuation time. According to the National Fire Protection Association (NFPA), the majority of fatalities from US home fires were located in a different room than where the fire started—which is exactly why interconnected systems save lives.

Built for your home's layout

Perfectly sized at 14.8cm diameter for discreet ceiling mounting, the Ei146e suits multiple rooms throughout your property. Install one in each bedroom, your living room, dining room, hallway, and landing. The compact design doesn't dominate your ceiling while the optical sensor delivers early warning for the types of fires most likely in domestic settings.

The Aico Ei146e represents a straightforward approach to comprehensive fire safety—mains-powered reliability paired with proven optical detection and intelligent interconnection, all meeting modern UK fire safety standards.
