The CO922 detector has been designed and built according to European regulations to detect the
presence of CO toxic gas.
A microprocessor is used to create a complete surveillance and control system with maximum flexibility.
Thanks to this and its other features, this detector is suitable for household applications.
The gas detected by the CO922 is Carbon Monoxide, when both the maximum CO admissible concentration
threshold of 300ppm is exceeded, and when low CO concentrations persist in the environment for lengthy
periods, which according to the principle of accumulation could also damage the human organism.
The probe can activate solenoid valves, sirens, and any other signal or alarm handling devices using the
built-in relay. A series of technical features make this detector extremely versatile, reliable, accurate,
and safe.
The relay, free of voltage, allows installation of multiple detectors on a single solenoid valve or suction
fan, ensuring control of multiple dangerous environments.
The detector is complete with a special circuit that controls the sensor’s efficiency level, and signals any
possible fault. The external container has an IP42 protection degree.
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 particular
environmental and / or installation standards.
This equipment is designed to protect individuals from acute exposure to carbon monoxide.
This equipment will not completely protect the Individuals with specific medical conditions.
In doubt, consult a doctor.
Important note
Before connecting the equipment, it is recommended that you read the instruction manual carefully and

Precautions
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.

Components and commands
BUZZER
1) MAINS connected indication LED. When the unit turns on, this LED blinks and a test of the gas detection
sensors’ efficiency status is carried out. This phase takes about 100 seconds. Afterwards the LED stays on
without blinking. During the test period, the CO922 does not detect the gas.
2) FAULT indication LED. If this LED turns on, it means that one of the gas detection sensors is not working
efficiently and must be replaced in an authorized centre. A relay is connected to the fault circuit as well as the
light indication and a “cricket” siren.
3) CO ALARM indication LED. This LED will light up when the gas concentration level has reached the 300ppm
concentration, or when the accumulation level is reached.
The relay contact is closed, and an impulsive sound is issued.
4) Electrochemical Cell sensor for Carbon Monoxide detection
5) TEST button. This button is used to simulate a gas leak, after installation.
6) Identification label, registration number and manufacturing year, located under the ABS small dome.
7) Label of the gas sensor expiration date.
This label must be applied by the technician during the installation and remembering that the gas
sensor must be reviewed after 5 Years

Installation measures and positioning
The position of the detector is a crucial factor for its correct functioning during gas detection. In order to obtain the
maximum results from a device and minimize the probability of false alarms, it is recommended to follow this scheme
and keep in mind the following general regulations. The CO922 is an equipment adapted to be mounted on a wall.
When installing is good to use reasonable care that requires an electronic device, and then:
- Install the detector away from sources of heat.
- Avoid that the liquids may come into contact with the detector, remembering that its box has a degree of
protection IP42.
The detector must not be installed
behind the barriers that hinder the
prompt detection of gas . near of
aspirators or fans and in areas where
the temperature falls below 10 ° C or
rises above 40 ° C.
The installation height of the detector C0922 must be from a minimum to a maximum of:
Minimum 160 cm. from the floor
Carbon monoxide gas detector
min. 1,60 from the floor
Turn on and testing
1) When powering on the CO922, you will see that the MAINS LED lights up and starts blinking for about 90 seconds.
Afterward the LED stays on without blinking, the CO922 is ready to detect.
2) Press the button placed on the side the sensor to simulate the presence of gas.
The Led alarm lights up, the relay changes the state of work.
Ceased the alarm, the Led turns off, it stops the sound of the buzzer and the connected devices will be disabled.
Test run with GAS
To test the toxic gas emit gas from a pre-calibrated bottle from 30 to 300 ppm, in the grey sensor, see item 5 (of page
3).
Using other types of gas could damage the sensor.
N.B. This test is recommended to be performed once a year.
