Gas DeTeCTIon

Control unit for 3 remote sensors

CTP21

Control unit is equipped with three led bars that indicate the reached gas concentration,

The green led indicates fresh air, the first and second red leds indicate pollution and the

third and fourth red leds indicate the switching on of the alarm relay. The yellow led

indicate an anomaly of the system and it operate on the fault relay.
