GS920
Gas Detector with Earthquake-proof Device
The GS920, thanks to its innovative
of selecting the "Intrinsic Safety Control", is a leading-edge technological device.
A microprocessor was used to create a complete surveillance and control system
with maximum flexibility.
Together with its catalytic sensor technology, it detects the presence of explosive
gas, such as: Methane and LPG, with trip threshold calibrated at 10% of Lower
Explosion Limit.
Using the built-in relay it can activate: solenoid valves, sirens, and any other alarm
signal device. The micro switch makes it possible to select the relay impulse
functioning, to connect manual reset solenoid valves, or the continuous functioning,
and to activate N.C. class "A" solenoid valves and sirens.
Another micro switch allows turning on/off the
The power supply unit allows driving of a manual reset solenoid valve with a 12Vdc
coil, without any buffer battery. If the voltage absorption is too high, you can later
integrate a suitable backup battery. The battery is recharged automatically.
The
"Seismic
Control" allows closure of the solenoid valve, stopping the gas
original source! This control is vital in seismic regions! The relay, free of voltage,
allows installation of multiple detectors on a single solenoid valve, providing control
of multiple dangerous environments.
The technical scheme is completed by a circuit that controls the catalytic sensor
"efficiency level", and signals any possible fault.
These technical features make the detector ideal for civil environment safety
according to EUROPEAN REGULATIONS.

INSTALLATION When performing the installation, please remind that if you pierce the GS920 container, it will lose its properties and its conformity to REGULATIONS. TERMS and EXPECTATIONS: 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. - Page 3 1 2 3 4 5 6 7 8 1) MAINS connected indication LED. When the green LED is blinking, the GS920 performs a test of the sensor’s efficiency status, and gets it to the functioning temperature. This phase lasts about 60 seconds.

- Page 5 Once the device has been turned on, the MAINS LED will start blinking for about 60 seconds, after which it will remain ON. Now the GS920 is ready for detection of explosive gas. After 24 hours from installation begin the self-learning antiseismic period (from this time the detector MUST NOT be moved from the installation position for any reason).

Felt by a people at rest, especially on the upper floors of buildings or in favourable position Felt by people indoors. Hanging objects swing. Vibration like passing of light trucks.
- Page 7 Check that the wiring is correct and that the jumper that carries power to the relay has been set properly. All relays are free from electrical power. Check the drawing of the connections. If other problems arise, a specialised and/or authorised technician and/or the Distributor of BEINAT S.r.l. should be contacted directly. Page 7...

Carefully follow the instructions and the connections according to Regulations in force, keeping in mind that the signal cables should be laid separate from the power cables. Connection Scheme of GS920 Detector WARNING ! The Relay is free of voltage. - Page 9 Electrical connections A 12VDC 1.2Ah battery can be connected to the GS920 gas detector. The detector itself provide the needed charge for the battery. The battery must be connected between the pin 3 and 4 (pin 3 is the positive, 4 is negative)
