The detector detects abnormalities in the air caused by presence of gases or other reasons (leak) with the
built-in gas sensor. The concentrations of detected gases are displayed on the seven-segment LED.
The detector has a built-in alarm contact and can be used either as a gas alarm, fault alarm, or common
(gas, fault) alarm.
