Heat Detectors

Rise in ambient temperature caused by fire 

Heat detectors are used in rooms where smoke detectors are incompatible. The heat detector reacts when the temperature sensor in the detector reaches a certain temperature. The detector can either react if the temperature reaches a certain level, or by fast temperature rise over time.

The Autronica heat detectors are designed for use with Autronica’s interactive fire alarm systems. It is a point heat detector for detection of rise in ambient temperature caused by a fire. The thermistor reads the temperature at the detector point. The SelfVerify® function is able to initiate the alarm at the correct temperature and is regularly checked and calibrated once every 24 hours.

Three main series are available:

  • 200 Series: BDH-200
  • 300 Series: BDH-300
  • 500 Series: BD-501, BD-505, BDH-500, BD-55
  • Interactive – Ensures fast response to various fire developments
  • Convenient – Plug-in detector head with heat detector intended for use in humid areas
  • High quality – Not influenced by dust, humidity, exhaust gases or electromagnetic fields i.e.: radio transmitters, cellular phones, etc.
  • Additional PCB coating – Ideal in humid environments
  • Convenient – Short circuit isolator in each detector, built-in alarm indicator (LED) and automatic addressing
  • Proven – Designed to meet the requirement of the major maritime classification societies
