• This detector is not a replacement for the correct installation, use and periodic
maintenance of combustion equipment, nor adequate ventilation of spaces in which these
devices are being used.
• We recommend you to weekly test the detector using the "TEST/SILENCE" button on the
detector.
• The detector's CO part only sounds the alarm when carbon monoxide is present at its
sensor. Therefore, it's possible for carbon monoxide to be present elsewhere and the alarm
doesn't sound.
• When the alarm sounds, possible harmful carbon monoxide levels are present!
Carbon monoxide can be deadly!

Alarm
When the detector sounds the alarm, carbon monoxide (CO) might be present
which can be fatal. Therefore, never ignore this alarm.
When there's an active alarm, the red LED will illuminate and beep tones are emitted. When the
smoke dissipates or the carbon monoxide concentration drops below 40PPM, the alarm will stop.
What to do when the alarm sounds:
1. Open doors and windows and immediately do outside into the fresh air. Check whether
everybody has left the building.
2. Call an official installer to inspect the correct functioning and state of maintenance of the
combustion source (gas or oil powered equipment) that could be the cause for the CO
alarm.
3. Only enter the building again after the cause has been resolved and the building has been
well ventilated.
The alarm sound can be switched off by pressing the TEST/SILENCE button.
It will only switch off in case smoke is detected.
