OVERVIEW
This detector is a microprocessor based electronic device that
answers all needs of safety in those cases in which there can be
CO production (e.g. where heating or coking appliances can
have uneven combustions).
The device is designed so that it simulates the behaviour of the
human body accumulating the gas.
The CO gas sensor is replaceable and is consists of an
electrochemical cell that is also sensitive to acetylene, hydrogen
and nitric oxide.
Therefore the user must take into account the effect of the cross
-sensitivity of the various gases.
Note: Carbon monoxide (CO) is a gas whose high toxicity (it can
have severe consequences even when inhaled in very small
quantities) is added to an extreme danger because it is not
percettible by people being colourless and odorless.
OPERATION
Commissioning
This detector has a built in delay that prevents the alarm to be
triggered (thus allowing the sensor to heat up) at power on or
when power comes back after a blackout. As soon as it is
powered the sensor will perform a diagnostic on the internal
circuitry (for a short while all three LEDS turn on) for an electric
check; afterwards the sensor will start to stabilize. After the
initial delay (about 1 minute) the green LED flashes: when it
stops flashing and stays steady the sensor is ready to operate.
Button ' T '
This is a multifunction key:
Test function
In order to check the proper operation of the sensor, once the
1 minute stabilization time is completed, just press for 2 seconds
the 'T' (test) key, located on the front cover: all green, yellow
and red LEDs turn on, while the buzzer activates; at the same
time also the relay is energised.
Internal buzzer mute function
In case of any fault (see section 'Faults') if the key 'T' is shortly
pressed, the internal buzzer is muted until a new fault should
happen.
In the event of an alarm pressing shortly the 'T' key results in its
muting for 5 minutes only.

Alarm state
230V~
When the CO concentration exceeds the 30 ppm (50 mg/m³)
starts the counting of the intervention time of the device; the
intervention time is variable with respect to at the concentration:
the higher the concentration, the shorter the intervention time for
the alarm.
The intervention time is in compliance with the EN 50291:

REPLACEABLE CO MODULE

The replaceable CO module is equipped with a microcontroller

85 x 107 x 38 mm (W x H x D)
(see section 'Faults'), located on the front cover, when the
~ 260 gr.
module life is at its end and it must be replaced.
In this case read carefully the section 'CO module replacement'.
FAULTS
This device features a self-diagnostics for a continuous check of
the CO module and the whole detector reliability.
The fault condition is evidenced by a short buzzer activation
every 10 seconds, together with the yellow LED flashing in
different ways, as described in the following table.
In case the yellow LED is turned on steady and the internal
buzzer beeps every 10 seconds, the fault is on the detector
board, which must then be replaced.

INSTALLATION
This device is intended for wall mount only, with relevant
electrical wiring made through the fixed wiring, not exposed to
people and connected to the fixed electrical wiring. The device
safety and operational features are only granted when the
electrical wiring is made through the proper opening for cables
located in the plastic plate.
To access to the internal terminals, remove the front panel by
loosening the screw (Fig. 2).
Make the electrical wiring following the suggested wiring
diagrams in Fig. 3, 4, 5 or 6.
Please note that the intervention delay is strictly dependant both
on a correct positioning of the detector in the room and to the
type of gas to be detected.
For 'light' gases (such as for CO) an installation at an high
altitude above the floor is advisable (about 180 cm from the
ground).
Please avoid to install this gas detector in any position in which
its operational features could be compromised, such as the
following:
- in an enclosed space (e.g. in a cupboard or behind a curtain;
- directly above a sink;
- above or close to the cooking board;
- next to a door or window;
- next to an extractor fan;
- in an area where the temperature may drop below - 10°C or
exceed + 40°C;
- where dirt and dust may block the sensor;
- in a damp or humid location.
