Heat detectors are devices for detecting heat sources. They are installed in rooms where smoke detectors can not be installed. They complete their action in your home, and give the alarm quickly in case of fire.

How does a heat detector work?

The heat detector integrates a temperature sensor. When the unit detects heat greater than 54° C in your environment, an alarm is triggered. This alarm, with a power of about 85 decibels, can alert those present quickly. The heat detector works with batteries. A sound signal is also emitted when the battery level is low.

There are hybrid heat sensors that analyze both:

  • The fixed temperature: an alarm is activated as soon as the temperature reaches a certain threshold.
  • The rate of increase of heat: the alarm is triggered when the temperature increases considerably compared to the average temperature of the room.

The heat detector has a life of 10 years. On your device is a label that tells you the recommended replacement date.

Where to install a heat detector?

The heat detector completes the smoke detector. It can therefore be placed in rooms where the smoke detector is not the most suitable solution such as the kitchen, the bathroom or a living room with a fireplace. In these rooms, a smoke detector could be triggered inadvertently. A heat detector is the ideal solution.

The heat detector must be installed 50 cm from the walls and at a distance from the luminaires so as not to disturb the detection of heat.

The heat detector is not mandatory, unlike the smoke detector. It nevertheless represents a reliable solution and an excellent fire protection. Other detectors also exist to provide you with daily protection.
