Fibre optical thermal detection

For very large installations, the use of many controllers can be a disadvantage for commissioning and maintenance work. A fibre optical thermal detection system can be used as an alternative for such installations.

SenseTek is the exclusive distributor of the FireLaser thermal fiber optic system in the Netherlands. The system consists of a centrally placed controller and one or more fibre optical sensor cables.

When a cable is projected in a loop, a redundant system is created, making it possible to route the cable through different fire detection zones. The cable can be divided into separate groups by software, according to the zonal borders. In this way, an alarm from a zone will be indicated on the controller as being from the relevant zone. Each zone has its own volt-free alarm contact. This makes it possible to connect the system to the fire alarm installation.

The cable is provided with a steel reinforcement which makes it very robust, despite its small diameter of just 3.3mm. This makes it very suitable for use in medium to large parking garages and industrial applications.

Fibre-based thermal cable systems have a reputation for being very expensive. The FireLaser system is a welcome exception. Installations with a cable length of approximately 900 meters can compete with the LIST Sensor cable system. Larger installations are generally even cheaper than a comparable installation based on the LIST Sensor cable system.

FireLaser has an EN54-22 certificate issued by VdS and can therefore be used in certified fire alarm systems.
