Loosen in the slot with a flat screwdriver (Fig.5) and open the cover
below the signal LEDs.
By pressing the TEST / HUSH button (Fig.6) you can:
l
Test the operation of the LEDs and BUZZER of the unit when the
detector is in ON mode.
In this case, the detector flashes one by one LEDs, associating each
one with a
Beep
.
We recommend you to do this at least once a week.
In case of anomalies contact support.
l
Silence the BUZZER sound (
Beep
) when the detector is in FAULT,
END LIFE and LOW BATTERY mode.
The gas detector will stop “beep” for 24 hours while the YELLOW LED
will continue to flash.
After 24 hours the BUZZER will be automatically switched on.
TEST/HUSH BOTTON
INSTALLATION
With the help of a screwdriver, unscrew the screw on the right side of
the product and remove the front panel (Fig.3).
Fig.3
Position the base correctly and secure it to the 3-module recessed box
or to the wall using screws and dowels supplied.
For fixing the dowels, pierce the wall with a tip of 5 mm diameter.
ON
OFF
Now the detector goes into stabilization mode.
Place the front part of the detector and screw.
- FAULT MODE
In this status the gas detector emits 2 “
Beeps
” and 2 “flashes” of the
YELLOW LED per minute (Tab 2).
This means that the
Beta
gas detector is no longer functioning prop-
erly and gas detection is no longer guaranteed.
The gas detector must be replaced.
You can silence the 2
Beeps
for a 24-hour period by pressing the
TEST / HUSH
key (see
TEST/HUSH
paragraph).

DETECTOR’S MODE
The table “Tab.2” shows all the operating modes of the
Beta
gas de-
tector.
Each MODE is recognizable by a specific number of flashes and / or
“
Beeps
” of the buzzer over a period of 1 minute.
Tab. 2
- ALARM MODE
In this mode the detector is detecting a concentration of carbon mon-
oxide over the alarm thresholds.
In this state, the detector emits “
Beeps
” and the RED LED flash inter-
mittently .
If the
Beta
gas detector is in ALARM status for more than 15 minutes,
to save battery charge, it reduces the “
Beep”
frequency and red LED
flashes
.
Only if the amount of gas measured in air is less than 300 ppm it is
possible to silence the buzzer for a period of 15 minutes by pressing
the
TEST / HUSH
button (see
TEST / HUSH
paragraph).
After that period, if the gas concentration exceeds the alarm thresh-
olds, the BUZZER will be automatically switched on.
The
Beta
gas detector is powered by a 3V 1400mAh lithium battery
- which guarantees its operation for at least 6 years (under normal
conditions).
After opening the front part, proceed as follows:
l
To turn on the
Beta
gas detector, move the JUMPER inside from the
OFF position to the ON position (Fig.4).
Each single LED will be blinking accompanied by a “
Beep
”.

FIRST TIME USE
- LOW BATTERY MODE
In this mode the gas detector emits 1 “
Beep
” and 1 yellow LED blink-
ing every minute (Tab 2).
It is also possible to silence the “
Beep
” for a period of 24 hours by
pressing the
TEST / HUSH
button ( see
TEST / HUSH
paragraph).
The gas detector must be replaced.
l
In a damp or wet wall.
l
In critical environments where dust and dirt can damage the gas
sensor.
where dust and dirt can damage the gas sensor.
STABILIZATION MODE
Once switched on, the detector needs a stabilization period of about
two minutes before working properly. During this period, the detection
functions are inhibited.
This state is represented by the synchronous flashing every 8 seconds
of the GREEN and RED LEDs.
After the stabilization period has elapsed, the detector switches to nor-
mal state ON.
- END OF LIFE OF THE SENSORS’ STATUS
In this mode, the gas detector emits 3 “
Beeps
” and 3 LED YELLOW
LED
flashes
every minute (Tab 2).
The gas detector has exceeded the maximum time in which the
operation is guaranteed.
- MODE ON
The
Beta
Gas Detector emits a flash of the GREEN LED every
minute.
This means that the
Beta
Gas Detector is active in the detection of
Carbon Monoxide (CO).
- SELF TEST
The
Beta
Gas Detector performs an automatic
self-test
every 10 min-
utes.
This is a check of the electronic components inside it, including the
sensor, to ensure the full functionality of the detector.
If the
Self-Test
detects problems, the detector switches to FAULT STA-
TUS.
