In order to grant a real safety, a gas detector must be coupled
to an electro-valve capable of blocking the gas flow in the event
of an alarm.
Both the gas unit and the solenoid valve must comply with the
law prescriptions in force in the country concerned.
BEAGLE detector can be connected to two types of electro-
valve:
- 230V~ Normally Open electro-valve;
- 230V~ Normally Closed electro-valve;
WARNING
The installer is reminded to fill in and apply the sticking label
supplied with the product by writing the installation date of the
product, the date before which the sensor module must be
replaced and last time and finally the date before which the
entire detector must be replaced.
The latter is stated on 15 solar years from the installation date of
the product.
This label must be applied, at installer care, on a visible side of
the gas detector once it has been fixed in its typical installation
position.
Warning label:
The CO module can be replaced twice only when no faults took
place or several times in case of CO module faults (in this case
remember to respect the whole detector replacement date).

SENSOR REPLACEMENT
Every five years (max twice) the internal sensor module must be
replaced with a new precalibrated sensor module.
The replacement must be done by qualified personnel according
to the following instructions:
1. Use the relevant sensor module part: code AC MC01.
2. Remove the power supply from the detector.
3. Remove the detector’s panel as shown in Fig. 2.
4. Spot the sensor module to be replaced:
5. Remove the old sensor module.
For removal just grab the sensor (arrow A) with one hand
while grabbing with the other hand the plastic spacer (arrow
B) and pull at the same time toward you.
6. Insert the new sensor in the relevant connector. Attention
must be payed in that the module’s pins match the
relevant detector’s female connector.
7. Reposition the front panel on the detector and tighten the
relevant screw.
8. Power up the detector and check for its correct operation.
9. Fill in the detector’s warning label or fill in the new label
supplied with the spare sensor module and stick it on the
detector.
Note: that the warning label’s date must be 5 years
ahead the set up of the new sensor module.

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 LE S turn on) for
an electric check; afterwards the sensor will start to stabilize.
After the initial delay (about 1 minute) the green LE 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 LE s 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
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:
Alarm state is identified with the red LE turned on steady
together with the continuous buzzer activation and the output
relay energising after ~30 seconds.
The relay can in turn a gas cutoff valve (i.e. a potential in direct
CO cause) and/or a fan for the extraction of the poisonous air
from the room.
While in this state if the key 'T' is pressed the buzzer is muted
for 5 minutes.
The Alarm state is self-resetting in case the CO
concentration drops belo 25ppm for at least 5 minutes.
REPLACEABLE CO MODULE
The replaceable CO module is equipped with a microcontroller
that monitors continuously the residual life of the
electrochemical sensor, and evidencing through the yellow LE
(see section 'Faults'), located on the front cover, when the
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 LE flashing in
different ways, as described in the following table.
In case the yellow LE is turned on steady and the internal
buzzer beeps every 10 seconds, the fault is on the detector
board, which must then be replaced.
SIGNAL FAULT TYPE
n° 1 FLASH CO module end of life
n° 2 FLASH CO module fault
n° 3 FLASH CO module end of life - CO module fault
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. 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.
In case of 'heavy' gases (as for LPG) an installation in low places
is advisable (about 30 cm from floor level), meanwhile for ’light’
gases like methane in high places (about 30 cm from ceiling
level).
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;
