Fire alarm system

Type 2108 represents a complete fire alarm system on one board. The components can be wired freely, making it possible to build up the system step by step until it is fully operational.

The integrated fire alarm centre, optical indicators and acoustic signalling devices make the setup suitable for realistic exercises.

Sensors and signalling

The system combines thermodifferential detectors, a smoke detector, a manual trigger, a main detector, inside and outside sirens, and optical alarm indicators.

A key depot and four terminating resistors are also part of the system.
