VISUAL AND ACUSTIC SIGNALS
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.
POSITIONING
INSTALLATION WARNINGS
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:
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:
l
50 ppm for 70 minutes
l
100 ppm for 20 minutes
l
300 ppm for 1 minute
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.
Concentration
of CO in air
100 ppm (0,01%)
400 ppm (0,04%)
1600 ppm (0,16%)
6400 ppm (0,64%)
12800 ppm (1,28%)
Symptoms on human
Light headache in 2-3 hours.
Light headache in 1-2 hours, rising after 2-3 hours.
Headaches, dizziness and nausea in 20 minutes, dying within 2 hours.
Headaches and diarrhea in 1 or 2 minutes, death in 10-15 minutes.
Death in 1-3 minutes.
The
Beta
gas detector has a sensitive element to the concentration of
carbon monoxide in the air.
GENERAL OPERATIONS
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.”
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).
If the
Beta
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.).
If the
Beta
detector is installed in a room without a combustion unit
(bedroom, living room, etc.).
l
Does be wall-mounted in line with the height of breathing of the people
in the room.
When the detector is switched to “ON” the GREEN LED (ON) flashes
every minute.
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 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.
