1. Thermal, 2.Smoke, 3.Light and 4.Combined.
1. The thermal transducers respond to increase of environmental temperature, and are subdivided into
+maximum ones to turn on when temperature is increased to critical level;
+differential - turn on when environmental temperature increases with the certain velocity;
+maximum - differential.
Smoke transducers can’t be set in rooms with air temperature below -3o°C and above 6o°C, relative humidity higher than 80%, and also in very dusty rooms and areas with acid vapours.
The light transducers respond to ultra-violet or infra-red radiation.
Combined transducers are based on principles of operation of both thermal and smoke transducers.
