Product Overview

The Ei166, Ei166RC and Ei166e are mains powered optical smoke alarms featuring a longlife lithium back-up battery. Since the Ei166 alarms have been discontinued, Ei Electronics (also known as Aico in the UK) have designed the new Ei3016 optical smoke alarm to be the perfect, fully compatible replacement.

The new Ei3016 can connect with any Ei160 series alarms still in your system, and it will even fit onto your existing Ei166 base without any need for an electrician. The optical sensor technology in the Ei3016 has been upgraded to be even less susceptible to false alarms than its predecessor.

  • Power: 230V mains powered with back-up battery
  • Backup Battery: Self-charging lifetime battery
  • Warranty: 5 year warranty
  • Also the recommended replacement for the Ei161 mains powered ionisation smoke alarm
  • Suitable for bedrooms, living rooms, hallways, landings 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
  • Fits onto your existing Ei166 alarm base (Easi-Fit base included to keep as a spare)
  • Memory feature – easy to identify an alarm that has previously sounded
  • CE and Kitemarked to BS EN 14604: 2005
  • Performs its own internal self-checks every 48 seconds to ensure the alarm is functioning correctly
  • Warning alarm 85dB at 3 metres
  • Large combined test and silence button

The simple installation process of the Ei3016 replacement alarm removes the need for an electrician. However, power to all alarm circuits must be cut before removing and replacing any mains powered 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.

Does the job, and easy to replace the unit Following a power cut-off, the unit was sounding permanently, so I currently have it disconnected, and I will re-try connecting it after a few weeks of leaving the battery to discharge. It may be coming back to you !
