Gas Detector with Seismic Device
To protect your family
The GS920 is a high-tech technical device thanks to the innovation of "Seismic detection" and
the ability to select the "Intrinsic Safety control".
To built this complete, highly flexible control system, we relied on a microprocessor which,
combined with the Catalytic sensor technology, detects the explosive gases such as METHANE
and LPG with an intervention threshold set at 10% of the L.E.L.
Through the built-in relay, the GS920 can active solenoid valves, sirens and any other alarm
signaling device.
Through a micro switch it is possible to choose between an impulse mode of the relay to connect
solenoid valves with manual reset and continuous mode, to operate normally closed solenoid
valves in class "A", and sirens.
With another microswitch, it is possible to enable or disable the "Positive Safety".
The power supply unit allows you to enable a manual reset solenoid valve with a 12 VDC coil,
without the need of a buffer battery.
With the "Seismic Control", the solenoid valve is closed if necessary, effectively stopping the
gas at the origin. This control is vital in seismic areas
The technical scheme is completed by the special "Control Circuit of the degree of efficiency" of
the catalytic sensor, which promptly signals any possible fault
These technical features make the detector ideal for civil environment safety according to
EUROPEAN STANDARD.
Important: Assembly / maintenance of the appliance must be carried out by qualified personnel
and in accordance with applicable laws and regulations.
The manufacturer assumes no responsibility for the use of products that have to comply with

CHECK the integrity of the detector after having removed it from the box.
Check that the data written on the box correspond to the type of gas used.
When doing the electrical connections, follow the drawing closely.
Any use of the detector for purposes other than the intended one is considered improper, and as a result of
which BEINAT S.r.l. therefore disclaims any responsibility for possible damages caused to people, animals
or objects.
TERMS and EXPECTATIONS: The installation of the detector, its ordinary and extraordinary maintenance,
and its out of service removal at the end of the functional life guaranteed by the manufacturer, must be carried
out by authorized and/or specialized personnel.
To use your gas detector for a long time and with satisfaction, use it with the following precautions in mind.
Do not wet it.
The detector is not waterproof if immersed in water or exposed to high humidity can be seriously damaged.
Do not drop it.
Heavy knocks or falls during transportation or installation can damage the appliance.
Avoid abrupt temperature fluctuations.
Sudden temperature variations can cause condensation and the probe could work poorly.
Cleaning
Never clean the device with chemical products. If necessary, wash with a moist cloth.
Absolutely avoid using any cloth dipped in thinners, alcohol and chemical detergents.
MAINTENANCE
The user periodically (every 6 months) must perform a check of the operation of the control unit by spraying
a suitable test gas at the base of the probes connected until the alarm condition is reached.
a) At least once a year make a more accurate check by a specialist technician.
b) Disapol of the detector must be carried out by qualified personnel.
Functional Features Of Gas Sensors
The installation of the GS920 detector, its ordinary and extraordinary maintenance, and its out of service
removal at
the end of the functional life guaranteed by the manufacturer, must be carried out by authorized and/or
specialized personnel.
The CATALYTIC technology sensor duration is guaranteed for 6 years (in clean air).
The detector’s functioning temperature ranges from -10°C to + 40°C.
WARNING!
The CATALYTIC probe does not tolerate a gas detection exceeding 100% of L.E.L., with consequent natural
death of the sensor.
Each immediate puff of gas that exceeds 100% of L.E.L. takes away months of life from the sensor.
The detector must be tested by simulating the presence of gas by issuing it from a pre-calibrated testing
aerosol.
A common cigarette lighter near the sensor does not guarantee excellent functioning.

1) Green LED on. When flashes, the GS920 performs a test of the sensor’s efficiencystatus, and gets it to
the functioning temperature. This phase lasts 60 seconds and stop flashing so the GS920 is ready to
detect.“During the first 10 days from the last reset (or power fault) the green LED will turn off at regular intervals
to signal the seismic auto-learning phase.
2) Yellow LED, FAULT and functional life wear indication“If this LED turns on, it means that the gas detection
catalytic sensor is not working efficiently and must be replaced by an“authorized technician.
The blinking of this LED indicates that the GS920 has detected a vibration.
3) Red ALARM signaling LED. This LED lights up when the amount of gas dispersed in the environment
exceeds the danger threshold, 10% of the L.E.L.

The GS920 is suitable for mounting externally on a wall
At the time of installation it is good to use the normal diligence that an electronic equipment requires, Therefore:
- Install the detector away from excessive heat sources.
- Prevent liquids from coming into contact with the detector, remembering that the external structure has an
IP42 degree of protection.
Must not be installed:
1) behind barriers that hinder the prompt gas detection.
2) near aspirators or fans.
3) do not install the detectors near: washcloths, air vents, heating or air conditioning devices, windows or
ventilation devices.
4) must not be installed in closed spaces such as: behind a curtain or inside a wardrobe.
5) in environments where the temperature is between -10 ° C. and + 40 ° C.
The detector is designed to detect different types of gas and according to these it must be positioned at different
heights.
These heights are:
- 30 cm. from the lowest point of the floor to detect heavy gases (G.P.L. etc.)
- 30 cm. from the highest point of the ceiling to detect light gases (Methane etc.)
- Install the detector 1m to 4m from gas appliances
Methane gas
max. 30 cm from the ceiling
LPG gas
max. 30 cm from the floor
After switching on the power, the Green LED starts flashing for about 60 seconds, after this time, the LED stays on steadily,
now GS920 is ready to detect gas only.
After 24 hours from installation, the device begins to perform seismic auto-learning;
The detector must NOT be moved from the installation site for any reason, GS920 is recording all
movements and noises of the installation site.
The duration of the registration lasts 11 days.
N.B. Operation, gas detection after 60 seconds, seismic detection after 11 days.
Testing
Press the button next to the detector capsule to simulate a gas leak, the ALARM LED lights up and the relay changes its working
status after 5 seconds.
Once the alarm is over, the LED goes off, the buzzer stops and the connected devices are deactivated.
To complete the general test, emit gas from a pre-calibrated gas spray within 10% of L.E.L.. Testing with a common cigarette
lighter could damage the sensor.
It is advisable to perform this test at least once a year.
IMPORTANT: the detector operation test must not be carried out with the gas valve open,
1) because it is very dangerous to do this test.
2) because it is not possible to calculate how many liters of gas are released into the environment, to activate the general alarm.
