How to test the DGS
To test the gas detector, press and hold the Test/Silence button (no. 5 in the figure above) for a few seconds - the red LED will flash
and the buzzer will sound beeps. If the detector is at fault, the yellow LED will flash and a trouble event will be reported. See
Malfunction signals below for more details.
Warnings and limitations
The DGS gas detector is NOT suitable as a smoke or fire detector.
This detector will not work if the power supply is disconnected or cut off for any reason.
The detector may worn out because it contains electronic components that may fail at any time. Test your detector at least once
every week.
Battery
The detector uses a 3V, CR123A Lithium battery for monitoring the AC power. The battery’s life expectancy is five years, with an
average of 20 activations per day. After replacing the battery, the detector warms up for one minute before going into test mode for
five more minutes.
After replacing the battery the detector warms-up for three minutes, before going to normal operation mode.
Low battery condition is detected when the battery voltage drops below 2.6V. After that the battery can last for up to one month.
Maintenance and Troubleshooting
The DGS must be tested once every week, to ensure it is working properly.
Malfunction signals
When an abnormal condition is detected, the gas detector indicates it by flashing the yellow LED and beeping the buzzer. Call service
immediately! Below are common abnormal conditions of the detector.
Condition
Yellow LED and buzzer
Low Battery
The LED flashes once along with the buzzer beeping, once every 48 seconds.
AC Power Loss
The LED flashes twice along with the buzzer beeping, once every 48 seconds; all detection and alarm functions
are suspended, until power is restored.
Trouble condition
The LED flashes three times along with the buzzer beeping, once every 48 seconds.
End of Life
The LED flashes four times along with the buzzer beeping, once every 48 seconds. In normal conditions, the
validity of the detector is five years, after which it needs to be replaced.
Boot Failure
The LED flashes continuously and the buzzer beeps twice, once every 48 seconds.
