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 Ei3000 series have a different shape to the Ei150 alarms. Please note that you will require an electrician to fit the new alarm.

The Ei156EK replacement smoke alarm kit has been specifically created to replace the discontinued Ei156, Ei156TL or Ei156TLH optical smoke alarms. The genuine Ei Electronics Ei3016 optical smoke alarm in this kit features a rechargeable lithium back-up battery and is completely backwards compatible, allowing you to replace however many or few of your alarms at one time, sure in the knowledge that the new alarms will fully interconnect and communicate as before.

  • Ei156EK kit contents:
    • 1 x Ei3016 optical smoke alarm manufactured by Ei Electronics
    • 1 x Ei1516 masking plate
  • Rechargeable lithium back-up battery (included)
