Description of functions
• Green LED lights up - the detector has been
connected correctly Fig. 2A.
• Orange LED lights up - the detector is indicating that
there is a fault Fig. 2B.
Maintenance
The detector can be fully tested using the test button
(also the mute button) Fig. 2E. Perform a test at least
once a month. Press and hold down the test button until
the red and orange LEDs fl ash and the audible alarm
sounds intermittently (approx. 85 dB). It is not su cient
to simply test operability by using a gas fi re device, such
as a gas lighter or a gas stove.
• If the red LED fl ashes and there is an intermittent
audible alarm, this means that the device has
detected gas Fig. 2C, please refer to the section
What to do in the event of an alarm. The alarm
output on the back of the device will be
activated Fig. 3A.
Cleaning the detector
When necessary (usually about twice a year), wipe the
device with a clean, dry cloth and clean the outside
with a vacuum cleaner. The FlammEx gas detector
automatically performs a self-test. If there is a fault,
the orange LED Fig. 2B will fl ash continuously. This
indicates that the detector needs to be replaced.

Potential for false alarms
You can silence the FlammEx gas detector by pressing
the test button. The red LED will continue to fl ash
and a short alarm will sound approximately every 45
seconds. To fulfi l its purpose and to ensure your safety,
the FMG 3637 FlammEx gas detector is designed to be
highly sensitive. The system's sensor may also react to
other gaseous media. The use of aerosols (propellants
in spray cans), as well as thick smoke and cooking
vapours, may trigger a false alarm.
Technical and design features may be subject to change without notice.
