6. Trådløs sammenkobling
The CO511 detector features wireless interconnection technology, allowing it to communicate with other compatible First Alert wireless alarms. When one interconnected alarm detects CO, all other interconnected alarms will sound, providing early warning throughout your home.
6.1 Linking Alarms
Refer to the detailed instructions in the full user manual for specific steps on wirelessly linking multiple CO511 units or other compatible First Alert wireless alarms. This typically involves a simple pairing process using the test button on each unit.
7. Betjeningsvejledning
7.1 Test af alarmen
Tryk og hold på Test/Stilhed button on the front of the alarm for a few seconds. The alarm should sound a loud siren and announce "Carbon Monoxide! Evacuate!" or similar. Test your alarm weekly to ensure proper function.
7.2 Afbrydelse af alarmen
If the alarm sounds due to a known, non-emergency condition (e.g., temporary CO from a gas stove), you can press the Test/Stilhed button to temporarily silence it. The alarm will reset after a few minutes if the CO levels return to normal. If CO levels remain high, the alarm will reactivate.
7.3 Voice and Location Feature
When CO is detected, the alarm will not only sound a siren but also provide a clear voice message, such as "WARNING! Carbon Monoxide! Evacuate!" If programmed, it will also announce the location of the alarm (e.g., "Basement").
7.4 Hvad skal man gøre, når alarmen lyder
- Immediately move to fresh air outdoors or open doors/windows.
- Call your emergency services (e.g., 911) or the fire department.
- Do not re-enter the premises until it has been cleared by emergency responders and the CO source has been identified and corrected.
8. Vedligeholdelse
