Gas Leak Detector GS-130
2/2
MEF51011
COMBUSTIBLE GAS DETECTOR GS-130
The GS-130 detects all mixtures of air and combustible gas (Natural Gas,
Methane, Propane, Butane, Acetylene, GPL, Hydrogen, etc). The detector
detects two levels of gas concentration - different output reactions.
The main GS-130 features are: high reliability and sensitivity, compact
size, 230V (110V optional) power supply and long stability & lifetime.

Note:
Although this product does not contain any harmful materials we
suggest you to return the product to the dealer or directly to the
producer after usage.
Installation
A professional should install the detector (recommended in
compliance with EN 50244).
Fix the detector on the wall. For gases lighter than air (natural gas,
city gas etc.) install it close to the ceiling, for heavier gases (propane,
butane, etc.) install it close to the floor. The detector should not be
located close to any obstacles protecting natural air circulation.

Memory
From the factory the memory function is disabled (when the
concentration of the gas drops down to normal, the GS-130 will stop the
alarm signal).
Close the MEM jumper to select memory function. Then the alarm
indication if triggered will not stop unless the GS-130 power supply is
terminated for a while.
External buzzer
You can connect an additional buzzer (model BZU-12) to the AUX
connector. The external sounder works the same way as the built-in
one.
Power supply
Connect power cord to terminals marked 230V AC (or 110V AC). The
power inlet should be fused with an external fuse (max. 10A).
Output relay function
There is a dry relay contact available on the GS-130 output terminals:
C
- common contact
NO
- normally open contact
NC
- normally closed contact
This relay output can be used for an automatic gas valve stop, alarm
system triggering or for other warning systems.
If the
REL jumper
is open, the relay will be triggered after the 1
st
level
of gas concentration is detected. If the REL jumper is closed, the relay
will be triggered after the 2
nd
level of gas concentration is detected.

Function
After switching the power on the green LED will flash for 60 sec. (the
detector warms up). When the green indicator lights permanently the
detector is ready.
If the gas concentration reaches the 1
st
level, short beeps will sound
and the red I. LED will go off.
If the gas concentration reaches the 2
nd
level, long beeps will sound
and the red II. LED will go off.
The output relay reacts depending on the REL jumper setting.
Warning - In the case of a gas alarm stay calm and act as follow:
- do not operate any switch
- do not use any kind of phone in the location of the gas leakage
- open windows
- stop the gas leakage if possible or leave the place and call a fire
company
Testing
Use a gas cigarette lighter (no flame) to test the gas detector reaction.
