Aico 12v Heat Detector (EI103R)
The Ei103R is an Optical Smoke Detector that runs on 12V DC power.
The detector gives a fire warning when the temperature at the unit reaches 58°C. Heat alarms are designed for use in kitchens and garages, where the use of Optical or Ionisation detectors would lead to unwanted nuisance alarms.
The detector has a pair of built-in Volt free relay contacts (i.e. can be used to switch into a burglar panel).
The detector 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 under such conditions.
