GAS LEAK DETECTOR GS-133

GAS LEAK DETECTOR GS-133
GAS LEAK DETECTOR GS-133
st
The GS-133 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-133 features are: high reliability and sensitivity,
compact size and long stability & lifetime.
If the REL jumper is open, the relay will be triggered after the 1 level
of gas concentration is detected. If the REL jumper is closed, the relay
nd
will be triggered after the 2 level of gas concentration is detected.

Function
After switching the power on the green LED will flash for 60sec. (the
detector warms up). When the green indicator lights permanently the
detector is ready.
st
If the gas concentration reaches the 1 level, short beeps will sound
and the red I. LED will go off.
nd
If the gas concentration reaches the 2 level, long beeps will sound
and the red II. LED will go off.
The output relay reacts depending on the REL jumper setting.
Complies with the essential requirements of: 89/336/EC EMC Directive Protection concerning electromagnetic compatibility when is used for its
intended purpose. Original of the conformity assessment can be found at the
web page www.jablotron.cz, section Technical support.
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
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.

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
Memory
From the factory the memory function is disabled (when the
concentration of the gas drops down to normal, the GS-133 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-133 power supply is
terminated for a while.
External buzzer
You can connect an additional buzzer (model BUZ-12) to the AUX
connector. The external sounder works the same way as the built-in
one.
Output relay function
There is a dry relay contact available on the GS-133 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.
Testing
Use a gas cigarette lighter (no flame) to test the gas detector reaction.
The detector will react after 15 seconds.
