Product Overview

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.

  • Power: 230V mains powered with back-up battery
  • Backup Battery: Self-charging lifetime battery
  • Warranty: 5 year warranty
  • Also the recommended replacement for the Ei151 mains powered ionisation smoke alarm
  • Replacements also available for the Ei154 mains powered heat alarm
  • Suitable for hallways, landings, living rooms, bedrooms and dining rooms
  • AudioLINK technology allows users to extract real time data to their smart phone or tablet
  • High performance optical sensor most suitable for detecting slow, smouldering fires
  • Available to purchase with the Ei1516 Masking Plate to hide blemishes on your ceiling
  • Supplied with an easi-fit baseplate
  • Memory feature – easy to identify an alarm that has previously sounded
  • CE and Kitemarked to BS EN 14604: 2005
  • Conducts self-checks every 48 seconds to ensure the alarm is functioning correctly
  • 85dB warning alarm at 3 metres
  • Large combined test and silence button

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.

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.
