Simple systems type "A" and "B"

They only perform the alarm and the automatic extinguishing function. For every spark detected the alarm will sound for 3 seconds and the nozzle will spray water for 3 seconds (1-2 liters).
Control panel operates and monitors all the functions of the system:

alarm for every spark detected
alarm for water leakage in the nozzle
duct valve closure and fan stop control
TEST function

The “A” type is the small simple system, suitable for “small” ducts, with diameter up to half a meter. It comprises only one detector and one spray nozzle.
The “B” type is the large simple system, suitable for “large” ducts, with diameter up to one meter. It comprises two detectors and two spray nozzles.
