Natural gas leakage alarm
1. Natural gas leakage detected
a. When the detector works normally and detects that the
concentration of natural gas is at or above the configured threshold
value, the indicator keeps flashing red once per second, and the
buzzer alarms loudly, with one beep per second and a pause every
three beeps.
b. After the detector alarms, a positive 12V pulse voltage signal is
output between wiring terminals T+ and T- to close the solenoid valve.
2. In case of natural gas leakage
a. Do not switch on or off any electrical appliance during the alarm of
the detector.
b. Do not cut off the power of the detector, and the detector can
above sound and light signals with a pause every three seconds, and
then release.
3. During the self-test, a forward direction 12V pulse voltage signal is
output between wiring terminals T+ and T- within 30 seconds to close
the solenoid valve.
4. A monthly self-test on the detector is recommended. Please contact
the after-sales service immediately in case of any faults.
