Installation of this appliance should not be considered as a substitute for proper installa-
tion, operation and maintenance of combustion appliances, including suitable ventilation
and drainage systems.
- This unit is designed to protect people from the acute effects of exposure to carbon
monoxide. It does not completely protect people with particular pathologies. In case of
doubt, consult a doctor.
- Long exposure to low levels (> 10 ppm) of CO may cause chronic effects.
In case of doubt, consult a doctor.
- The CO alarm device conforms to European Standard EN 50291-1: 2010 "Electrical
Appliances for Detecting Carbon monoxide in domestic environments."
INTRODUCTION
The Beta gas detector can be installed in domestic environments.
This appliance should only be used for the detection of carbon mono-
xide ("CO").
Carbon monoxide is a very poisonous, colorless and odorless gas pro-
duced due to bad combustion.
The high poisonous of the CO can causes - even at very low con-
centrations, if exposed for a long period - nausea, cephalia, loss of
consciousness. If exposure to higher concentrations is continuous, CO
may lead to death, having the ability to bind to blood much more easily
than oxygen. In this regard, we give the following table to clarify the CO
dangerousness in function of its concentration and exposure:
Concentration
of CO in air
100 ppm (0,01%)
Light headache in 2-3 hours.
400 ppm (0,04%)
Light headache in 1-2 hours, rising after 2-3 hours.
1600 ppm (0,16%)
Headaches, dizziness and nausea in 20 minutes, dying within 2 hours.
6400 ppm (0,64%)
Headaches and diarrhea in 1 or 2 minutes, death in 10-15 minutes.
12800 ppm (1,28%)
Death in 1-3 minutes.
Tab.1
It is evident from the above that the CO detector, having to provide a
preventive action, must intervene at very low concentrations, before
that the concentration of CO absorbed by the organism becomes per-
nicious.
The unit is calibrated at the factory to signal the alarm when a CO con-
centration is measured in the air of:

These thresholds are guaranteed by the manufacturer for a period
of more than 6 years after this period or when the "FAULT" LED is
switched on, the product must be replaced.
On the front of the detector is also indicated the date beyond which the
product must necessarily be replaced.

GENERAL OPERATIONS

The Beta gas detector has a sensitive element to the concentration of
carbon monoxide in the air.

When the detector is switched to "ON" the GREEN LED (ON) flashes

English
When the concentration of carbon monoxide (CO) measured in the air
by the detector exceeds one of the three predefined alarm thresholds it
turns to the "ALARM" mode by activating it with 0.5 sec intermittence.
the buzzer and the RED LED.
in
This detector features with three luminous signals:
- GREEN LED (ON): STATUS ON in normal operation or in
stabilization.
- YELLOW LED (FAULT): The detector does not work pro-
perly and must be replaced.
- RED LED (ALARM): Indicates the status of alarm for ex-
ceed ed concentration of carbon monoxide (CO) or stabiliza
tion mode.
A complete description of the detector's mode can be found on the next
page in the "DETECTOR'S MODE" section.
Warning: the instrument must be installed and put out of order
by qualified technical personnel.
Beta
detectors must be installed in each room containing a combus-
tion appliance and additional detectors should be installed to ensure
that proper signaling is provided to the occupants of other premises
(eg remote areas or bedrooms).
Beta
If the detector is installed in a room containing a combustion equi-
pment:
l It should be installed at a height higher than any door or window and
close to the ceiling.
l If installed on a ceiling, it must be installed at a distance of 30 cm from
any wall.
l If installed on a wall, it must be located at a distance of 15 cm from
the ceiling.
l It should be installed at a distance of 1 to 3 mt from the gas utilities
(kitchen, boiler, etc.).
Beta
If the detector is installed in a room without a combustion unit
(bedroom, living room, etc.).
lDoes be wall-mounted in line with the height of breathing of the people
in the room.

The appliance MUST NOT BE INSTALLED:
l On a shelf.
l Directly above the washbasin or gas appliance.
l In closed rooms or corners where there is no free air circulation.
l Near to walls or other obstacles that can block gas flow from the
user to the detector, or aspirators and fans that can deactivate air-
flow.
l In environments where the temperature may reach above 45 ° C
or below -10 ° C.
