Screen Display - Alecto COA-28 Mode D'emploi

BATTERY INFORMATION INDICATION:
Every 45 seconds, the battery is checked automatically.
The green power LED will flash every 45 seconds for as long as the battery power is higher than
3.5 Volts. This means the battery capacity is sufficient. As soon as the battery power drops below
3.5 Volts, a beep tone will be emitted when the green LED flashes briefly. At that time, please
replace the batteries as soon as possible.
The display also shows a battery capacity monitor:
Full
Half
Low
Empty
When empty batteries are indicated, the batteries should be replaced as soon as possible.
Use High Energy Alkaline batteries (3 x LR6 / 1.5V AA).
Remark: Rechargeable batteries are not suitable.
With both the supplied batteries and most A brand batteries on the market, it will take
approximately one year before the batteries run empty.
TESTING AND RESET:
Testing:
When the CO detector is working under normal conditions, the sensor and siren should be tested at
least every month by pressing the "TEST"/MENU" button.
Press the "TEST/MENU" button. The "POWER","FAULT" and "ALARM" LEDs will illuminate. The
detector will then emit 4 beeps while the red "ALARM" LED flashes 4 times. When the display
shows everything is in order.
If the sensor detects an error, the yellow "FAULT" LED will flash 2 times while 2 beep tones are
emitted. The display will now show .
Reset:
The alarm can sometimes activate because of environmental influences, for example due to smoke
with certain carbon monoxide concentrations or other chemical gases that are not life-threatening.
In this case, you can press the "TEST/MENU" button provided that the CO value is below 150PPM.
The alarm will stop and the detector immediately starts checking the gas again. If the concentration
is above 150PPM, it'll be impossible to stop the alarm. The red LED continues flashing, but the
siren will stop for 5 minutes. If the concentration is still above 150PPM after those 5 minutes, the
alarm will continue.
ALARM DISPLAY AT ACTIVE ALARM:
When there's an active alarm, the red "ALARM" LED will illuminate, 4 beep tones are emitted
continuously and the display will illuminate. When the carbon monoxide concentration drops below
40PPM, the alarm will stop.

SCREEN DISPLAY:

The LCD display shows the concentration of carbon monoxide. The value has a range of 25 -
550PPM ±10%. When the concentration is above 550PPM, the text appears which means a
high carbon monoxide concentration and therefore a high risk. All people and animals should leave
the area as soon as possible.
