Product Overview

The Ei150 series smoke alarms are not in production any longer. We have therefore created a replacement kit containing the Ei3016 smoke alarm which can replace an individual Ei150 smoke alarm without having to replace all alarms in a system. The kit also includes a handy masking plate to cover blemishes on the ceiling, as the Ei3016 series have a different shape to the Ei150 alarms. Please note that you will require an electrician to fit the new alarm.

The Ei151EK replacement alarm kit has been designed to replace the now discontinued Ei151, Ei151TL, Ei151TLH ionisation smoke alarms. The Ei3016 optical smoke alarm included in this kit features a ten year sealed lithium backup battery and backward compatibility with existing Ei150 series alarms, which means that you can replace one or all of your alarms without worry, they will still interlink and communicate as before.

  • Ei151EK kit contents:
    • 1 x Ei3016 optical smoke alarm manufactured by Ei Electronics
    • 1 x Ei1516 masking plate
  • Rechargeable lithium back-up battery (included)
  • Test and Hush (silence) buttons
  • 5 year warranty
  • Kitemarked to BS EN 14604: 2005
  • Suitable for installations complying to BS 5839-6: 2019 Grade D1

Please note: Due to the manufacturer discontinuing the Ei150 series smoke and heat alarms you will require a qualified electrician to install these alarms.

An impressive upgrade on my old smoke alarm. I bought a 2nd alarm after successfully fitting the 1st one. Having some DIY experience is advisable.

Great replacement smoke detector Replacement of obsolete smoke detectors was very simple. Did not even need the cover pice as the new detector covered the existing position. Wiring very simple. The fixing plate has multiple holes for screw fixings which matched the existing perfectly. Great piece of kit.
