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. The
SEGUGIO (Fig. 1) 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 cooking
appliances can have uneven combustions).
Indications are pre-set on three different alarm thresholds:
1° THRESHOLD (Pre-alarm CO) = red LED blinks slowly and
the
UHOD\
turns on (as an example to turn on a light indicator)
for CO>16 ppm (20mg/m³) concentration.
2° THRESHOLD (Main-alarm CO) = red LED, buzzer and
HDFK
UHOD\V
are turned on for CO>80ppm (100mg/m³) concentration.
3° THRESHOLD (Main-alarm remote sensor) = red LED blinks
quickly, buzzer and
HDFKUHOD\V
are turned on.
The
UHOD\
can close a gas distribution valve, possible CO
generation source and/or turn on a fan to ventilate the room.

.
The SEGUGIO detector is equipped with a delay line which
avoids the intervention of the alarm system (in order for the
electrochemical cell sensor to heat up) whenever the device is
turned on or even, after a mains blackout, when the power
comes back.
During this time delay (about 1 minute), the yellow LED is
blinking and, at the end, is turned off in order to indicate the
'active' state for the detector itself. During normal operation the
detector samples the CO concentration every 15 seconds.
The SEGUGIO detector also features an auto-diagnostic system
for checking the sensor good conditions. When the yellow
indicator is turned on (sensor fail), the possible causes must be
searched among the following:
- sensor fail;
- sensor disconnected;
- detector misfunctioning.
A functional test of the overall detector system can be executed
pressing the test button: the alarm condition is entered for a few
seconds allowing the test of the red led, the buzzer and the
relays.

In order to reach the wiring zone, remove the plastic plate on the
cover as indicated in Fig. 2 and remove the screw located
underneath.
Make electrical wirings as indicated in Fig. 3, 4 or 5.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 'light' gases as CO an installation in high
places is advisable (roughly 180 cm. from floor). Please avoid
installation in such a position that it can be directly in the stream
of smokes or vapours containing compounds which are
dangerous for the sensor health (as an example: do not position
the detector in the stream of fat smokes produced by cooking).
Do not use the following products in the immediate vicinity:
-
silicone compounds as, for instance, spray, aerosols,
lubricants, polishers, adhesives, paints, cleansing agents, etc
- solvents and diluents as, for instance, IPA (isopropyl alcohol),
methylbenzene, xylene, ethylene, acetylene, etc.
Clean the device only using a cloth damped with water.

The installer shall complete and apply the adhesive label
supplied with the product reporting the date by which the detector
must be replaced. This date corresponds to 5 solar years from its
starting date. The label must be applied by the installer onto a
visible part of the unit in the typical installation position.

: in case of CO detection alarm:
1) Ventilate immediately the room opening doors
and
windows.
2) Turn off any functioning combustion device.
3) Search and remove the possible cause of
alarm.
4) In case the cause of the alarm is not immedi
ately removed, vacate the room and call a
qualified technician.
