CHECK the integrity of the unit 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.
IMPORTANT: Do not test the device using the gas tap as this does not necessarily provide sufficient concentration
to activate the main alarm.
TERMS and EXPECTATIONS: The installation of the CO922 gas detector, its ordinary and extraordinary maintenance,
every six months, and its out of service removal at the end of the functional life guaranteed by the manufacturer, must
be carried out by authorized or specialized personnel.
In order to achieve long and satisfactory use of your CO922 gas detector,, use it by respecting the following precautions.
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 detector could work poorly and could become very
sensitive, and generate false alarms.
Do not allow it to become wet.
The control unit can be seriously damaged as it is not waterproof either when immersed in water or exposed to high
levels of humidity.
Cleaning
Never clean the device with chemical products. If necessary, wash with a moist cloth.

Operating specifications of the gas sensors
The ELECTROCHEMICAL CELL technology sensor has a duration of: 5 years.
The sensor’s functioning temperature, independently of the technology used, ranges from -10°C to +40°C
ATTENTION!
To test the toxic gas, issue gas from a pre-calibrated aerosol from 30 to 300 ppm, into the grey sensor.
Using other types of gas is useless and could damage the sensor.
The detector must be tested by simulating the presence of gas issuing it from a pre-calibrated aerosol.
Precautions
Technical Specifications
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.
• At least once a year make a more accurate check by a specialist technician.
• Disabling the detector must be carried out by qualified personnel.
