The Ei156 mains powered smoke alarm has now been discontinued by the manufacturer. The design of the base has also been changed so a whole new alarm and mount is required. Original manufacturer Ei Electronics (Aico) recommends the new Ei3016 optical smoke alarm as the most suitable replacement.
The Ei3016 can interlink with any Ei150 series alarms remaining in your system. Like the Ei156 it replaces, the Ei3016 features a lithium back-up battery and optical sensor technology that is less prone to false alarms. Because the base and connector plug for the Ei150 series are no longer used, a replacement base is included with your new alarm that will need to be fitted by an electrician using your existing wiring.
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 Ei156 alarms. However, the same power and interlink wiring from your existing connector can be used for the new base.
The tables below show all the products that can interlink with this alarm.

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.

Easy fit replacement An explanation of what to do with the second blue wire would be helpful as the old unit was a four wire connection and this replacement is a 3 wire connection.
