Velocimetric heat detectors monitor the temperature increase within the area in which they are installed. A microcontroller analyses and compares the signal it receives from a precision NTC-type temperature sensor, triggering an alarm if the temperature rise exceeds 5°C per minute.

- Absorption in alarm: 23 mA@20Vdc
- Static alarm threshold: 58° C ± 5%
- 3-colour LED: red alarm - green normal operation - green flashing with yellow
