6.6 Fire detector and smoke detector

6.6.1

Fire detector

The fire detector is a heat detector intended to check the temperature conditions before a fire bursts out. When the
temperature exceeds the threshold setpoint or when a quick change in temperature is experienced, a relay gets
activated to warn about an alarm condition. The detector is incorporated in and is an active part of all alarm systems
intended to implement a fire detection line.
The installer is responsible for detector installation and wiring.
Refer to the instructions provided together with the detector and to the wiring diagram of the unit for
installation and commissioning.
6.6.2

Smoke detector

The smoke detector is an optic detector responding in presence of combustion products (visible smoke). The principle
of operation is based on the scattering of light technique (Tyndall effect). The detector is incorporated in and is an
active part of all alarm systems intended to implement a fire detection line.
The installer is responsible for detector installation and wiring.
Refer to the instructions provided together with the detector and to the wiring diagram of the unit for
installation and commissioning.
We reserve the right to make changes without any prior notice.
