Description  Videos Downloads FAQs Technical
The Ei164RC is a Heat Alarm that runs on 230V AC mains power, and has built in tamper-proof rechargeable Lithium cells that act as a battery backup in the event of mains failure. These rechargeable cells are designed to have a ten-year life and outlast the life of the heat alarm itself, whilst providing up to 6 months of heat alarm operation without mains power.

The Alarm gives a fire warning when the temperature at the unit reaches 58oC. Heat alarms are designed for use in kitchens and garages, where the use of optical or ionisation alarms would lead to unwanted nuisance alarms.

The alarm is supplied with an Easi-fit base that allows very quick and simple installation, combined with simple installation simple alarm removal and replacement. The Easi-fit base automatically connects both mains power and battery as the detector head slides on.

Remote Control capability allows the alarm to be controlled remotely by either a “Test, Silence and Locate”Switch (Ei1529RC) or a Manual Call Point (MCP401RC). If the alarm is also connected to other Ei “RC” mains powered alarms then the whole system can be controlled remotely.

The alarm has other advanced features such as built in circuitry to aid suppression of voltage transients and RF interference to further reduce the chances of false alarms.


  • The green indicator will illuminate to show mains power is present
  • The red indicator will flash every 40 seconds to show that the alarm has performed an automatic self test
  • The red indicator will flash rapidly to show an alarm condition on the alarm that has triggered
  • The “Test/Hush” button will either silence false alarms (if briefly pressed) or to perform a self test (if pressed and held)
  • In “Test” mode the alarm will perform a self test and emit a full alarm sound
  • In “Hush” mode the alarm enters a ten-minute period of reduced sensitivity to overcome false alarm conditions. It will then automatically reset
  • When interconnected to other Ei mains powered alarms, if one alarm is triggered, it will trigger all other interconnected alarms (only the triggered alarm will flash a red indicator)
  • The alarm will emit a beep every 40 seconds to indicate that the battery back-up is depleted and needs recharging
