Mains powered heat alarm with hush button from Ei Electronics, Ei144e, is suitable for installation in kitchens and garages where a smoke alarm would be more prone to false alarms. The Ei144e features a 9V alkaline back-up battery, which provides power to the alarm even in the event of a mains power failure ensuring that your home is still protected. The Ei144e replaces the previous Ei144 models but can still be used to extend and interlink to an existing Ei140 system.
Please Note: When replacing an existing Ei140 or Ei160 series alarm, the simple installation process of this alarm negates the need of an electrician as they use the same base plate.
