The Ei151 is a mains powered smoke alarm with a lithium back-up battery. As the Ei151 is now discontinued, Ei Electronics (also known as Aico) have developed the Ei3016 optical smoke alarm as the most suitable replacement because it can interlink with any Ei150 series alarms remaining in your system. The rectangular base and connector of the Ei151 is no longer supported and will need to be replaced by an electrician to use your existing wiring.
The Ei3016 features new optical sensor technology that is less prone to false alarms than the ionisation technology of the Ei151, making it suitable for use in a wider range of locations. Bedrooms, hallways, landings and living areas, plus rooms adjacent to kitchens (but not within kitchens) are all perfect locations for the Ei3016. A rechargeable lithium back-up battery will ensure you remain undisturbed by low battery warnings for up to 10 years.
- Power: 230V mains powered with back-up battery
- Back-up Battery: Self-charging lifetime battery
- Warranty: 5 year warranty

Please note: Due to the manufacturer changing the design of their baseplates, you will require an electrician to install these alarms in place of your old Ei151 alarms. However, the same power and interlink wiring can be used for the new base.

Wiring Explained
Mains powered Ei Electronics smoke and heat alarms require a 230V AC power supply and up to 12 alarms can be hardwire interlinked in one system.
To obtain a mains power supply, each alarm can be connected to the nearest lighting circuit using 2 core and earth cable with a separate, dedicated interlink cable connecting all alarms. However, if possible it is recommended that the alarms are all powered from a dedicated circuit from the distribution board using 3 core and earth cable for safety during maintenance, as the interlink cable will carry power from live alarms on other power circuits. Please see the diagram below:-
