5.2 Commissioning
As soon as the CO alarm has been properly con-
nected to the current supply, an automatic self-test
is conducted:
1. The green POWER LED flashes for up to 90
seconds.
2. The green, yellow and red LEDs then flash
alternately.
3. Three crossbars will appear on the display. This
takes approx. 50 seconds.
4. A signal horn sounds when the self-test has been
successfully completed.
5. The green POWER LED then indicates that the
alarm is operational.
Exception:
The green POWER LED will flash for 90 seconds if,
during commissioning, there is already a CO
concentration sufficient to trigger an alarm. The
system then switches into operating mode and the
prevailing CO concentration shows on the display
for 15 seconds. Depending on the CO
concentration, the alarm signal triggers with the time
delay specified in the chapter entitled '5.3 Operating
functions'.
5.3 Operating functions
Normal mode
The green POWER indicator lights continuously.
The CO alarm is operational.
Alarm
The device emits an alarm if the sensor registers
a carbon monoxide concentration in excess of the
sensitivity threshold set in the factory:
A repeating sequence of 4 signal tones with
simultaneous illumination of the ALARM light is
output.
A signal is fed to the heater which is turned off
immediately.
The alarm continues until the carbon monoxide
concentration falls below the preset sensitivity
threshold.
WARNING
Do not disconnect the CO alarm in the
event of an alarm!
ITA-35 RCS
Alarm thresholds
50 ppm
100 ppm delay between 10 and 40 minutes
300 ppm delay less than 3 minutes
Mute function
If necessary, the acoustic alarm during the alarm
status can be turned off for 5 minutes by pressing
the TEST button. The red ALARM light will continue
to flash.
The acoustic alarm will sound again if carbon
monoxide is still present after the 5- minute mute
phase.
Note:
The mute function cannot be activated if the carbon
monoxide concentration exceeds 350 ppm.
The mute function can only be used once during an
ALARM phase, i.e. the acoustic alarm can only be
suppressed once for a period of 5 minutes.
Returning to normal mode
The alarm ends if the carbon monoxide concentra-
tion falls below the preset sensitivity threshold. The
green POWER indicator lights continuously.
Fault display
The CO alarm carries out a continuous self-test.
Flashing of the yellow FAULT indicator indicates
the presence of a fault. In addition, two short signal
tones are issued per minute.
If the FAULT indicator is active, there is a defect
in the device or the CO alarm is worn out after a
service life of approx. 6 years.
The CO alarm must be replaced in this case!
5.4 False alarm
To fulfil its purpose, the carbon monoxide alarm is
set so that it is very sensitive. The system's sensor
can therefore also respond to other gaseous media.
The use of aerosols (propellants in sprays, etc.)
and high tobacco smoke concentrations can also
trigger an alarm. The device can also react to brief
emissions of exhaust gas, for example, when the
equipment starts.
