The CHCODetector has been designed and built according to European regulations to detect the presence
of toxic and explosive 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.
IThe CHCO Detector can detect the presence of two gases.
The first gas detected is Methane, with trip sensitivity calibrated at 10% of L.E.L.
The second gas detected 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 built-
in relays. 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 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.

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.
TERMSand EXPECTATIONS: The installation of the CHCO gasdetector, its ordinary and extraordinary maintenance,
every six months, and its out of service removal atthe end of the functional life guaranteed by the manufacturer, must
be carried out by authorized or specialized personnel.
Inorder to achieve long and satisfactory use of your CHCOgas detector,, use itby 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.
Above about +40°C, the detector 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.

Precautions
Operating specifications of the gas sensors
The ELECTROCHEMICAL CELL technology sensor has a duration of: 5 years.
The CATALYTIC technology sensor has a duration that can vary: from 5 to 6 years.
The sensor’s functioning temperature, independently of the technology used, ranges from -10°C to +40°C
ATTENTION!
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.
To test the toxic gas, issue gas from a pre-calibrated aerosol from 30 to 300 ppm, into the grey sensor.
Please see point 6. 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.
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.

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 CHCO 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) Explosive GAS ALARM indication LED. This LED will light up and blink when the gas concentration level has
reached 10 % of LEL. The relay contact is closed, and an intermittent sound is issued.
5) Electrochemical Cell sensor for Carbon Monoxide detection
6) Catalytic sensor for Methane explosive gas detection.
7) TEST button. This button is used to simulate a gas leak, after installation.
8) Identification label, serial number and manufacturing year, located under the ABS small dome.
9) 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.

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 CHCO 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 installation height of the detector CHCO must be from a minimum to a maximum of:
Maximum 30 cm from the highest point of the ceiling
Minimo 160 cm. from the floor
1) When powering on the CHCO, you will see that the MAINS LED lights up and starts blinking for about 90
seconds.
Afterward the LED stays on without blinking, the CHCO 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
a) To test the explosive gas emit the gas from a pre-calibrated bottle within 20% of the LEL inside the sensor
concerned, see item 6 (of page 3).
N.B. This test is recommended to be performed once a year.
Nota: Do a test with a common cigarette lighter could damage the sensor.
b) 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.
