1) MAINS connected indication LED (ON).
2) FAULT LED and decadence of the functioning period
If this LED turns on, it means that the gas detection catalytic sensor is not working efficiently and must be
replaced by an authorized service center.
3) ALARM LED. This LED turns on when the amount of gas dispersed in the environment exceeds the danger
threshold, 10% of the LEL
4) Label.
This label must be applied by the technician during the installation
and remembering that
the gas sensor must be reviewed after 5 Years.
5) JUMPER to select the relay functioning mode closing the two poles, the relay will work at pulse, in the sense
that once tripped the alarm relay will close the C and NA contacts for about 90 seconds, and then will reopen
them. This is needed to prevent damaging some types of manual reset solenoid valve coils. By opening the
two poles, the relay will be set to continuous functioning.
6) Relay. The alarm relay switches when the detector has exceeded the threshold for gas setting.
7) Catalytic sensor for Methane or LPG explosive gas detection.
8) TEST button. This button is used to simulate a gas leak, after installation.
9) Identification label, registration number and manufacturing year, located under the ABS small dome.
