The Ei156 mains powered smoke alarm has now been discontinued by the manufacturer. Original manufacturer Ei Electronics (Aico) recommends the new Ei3016 optical smoke alarm as the most suitable replacement. Capable of interlinking with any Ei150 series alarms remaining in your system, the Ei3016 features a lithium back-up battery and optical sensor technology that is less prone to false alarms.

  • 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.
