What you need to know about gas detectors
The FlammEx gas detector raises the alarm if there is a
leak of natural or bottled gas. Warning! If these gases
leak out and mix with oxygen, a highly flammable
gaseous mixture will develop. Even the smallest of
sparks can cause an explosion. The FlammEx gas
detector raises the alarm long before a flammable
mixture is formed. Depending on the concentration,
you may be able to smell the gas before the alarm is
triggered.
Important information
The device should only be installed by a
competent person. Gas detectors are not a
substitute for smoke, fire or other alarms. This
detector is only intended for use in private
properties, such as houses, flats, camper vans/mobile
homes, sailing boats/motor boats. The gas installation
and any safety shutdown equipment must comply with
local regulations (see, for example, EN-1775).
The FlammEx gas detector must be replaced after
approximately 5 years. Pay close attention to the
instructions provided in this user guide when
installing your FlammEx gas detector.
What to do in the event of an alarm
1. As soon as the alarm sounds, try to determine and
eliminate the cause and/or evacuate the building.
2. Open doors and windows fully.
3. Avoid naked flames.
4. Do not press any electrical switches.
5. Wherever possible, arrange for a technician to
repair the gas leak.
How to maximise safety
We recommend installing the FlammEx gas detector in
areas where there is a connection to the gas system
or gas appliances. The alarm must be clearly audible.
Mounting position
• Do not install in the immediate vicinity of gas
appliances (e.g. directly above a gas stove or
boiler).
• The device should not be installed in areas with
high levels of humidity or steam, nor in very dusty or
dirty areas.
• Natural gas is lighter than air, which means that
it will rise. Attach the gas detector to the wall,
approximately 30 cm below the ceiling.
• Bottled gas is heavier than air, which means that it
will sink towards the floor. Attach the gas detector
to the wall, approximately 30 cm above the floor.
Device installation and start-up
• Once you have worked out the correct place to
mount the detector, fix the mounting plate to the
wall using the wall plugs and screws provided
Fig. 1A .
• Place the gas detector on the mounting plate and
push it down until it clicks into place Fig. 1B .
• Connect the plug to the electric socket to launch
start-up Fig. 2D . The device will not work if the
power fails!
• The green LED Fig. 2A will flash for approximately
10 minutes (warm-up phase). The device is ready for
use once the green LED lights up continuously.
• Press the test button Fig. 2E (for up to 5 seconds)
until a loud, intermittent alarm can be heard and the
red LED flashes Fig. 2C .
• Use the terminal on the reverse of the detector
Fig. 3A to relay the alarm. 9 V will be emitted via this
terminal if the alarm is triggered.
