FireAngel FA6813 four-chirp red alarm on CO detector: danger
Risk level
Critical
Stop using the equipment and contact a professional.
Urgency
Immediate
Quick answer
Get everyone out into fresh air now, call 112 or your local emergency number if anyone has a headache or nausea, and stay out until emergency services say it is safe. Four repeated chirps with a red flash on the FA6813 warn of dangerous carbon monoxide.
Safety first
What to do now
- Get everyone into fresh air and call 112 if anyone feels ill
Who: you and everyone in the home, without staying behind to look for the source. How: open doors and windows only if they are on your way out and it is safe; FireAngel asks you to stop using fuel-burning appliances and turn them off if possible, so do that only if you pass them anyway and without lingering. Result that matters: nobody keeps breathing air that contains carbon monoxide while help is on the way. If someone has a headache, nausea, dizziness or drowsiness: call 112 or your local emergency number and say you suspect carbon monoxide poisoning. If nobody has symptoms: stay outside and ring your gas or fuel supplier's emergency number, as the manual instructs. Evidence to keep: the time the alarm started and who was inside.
- Stay outside until you are told it is safe to return
Who: every occupant, waiting outdoors or at a neighbour's. How: FireAngel warns that, depending on the CO level, it can take up to 10 minutes for the sensor to clear and the alarm to stop; do not go in while it sounds and, even once it stops, wait for emergency services to say so. Result that matters: avoiding a return to a home where the gas has not yet cleared. If it is still sounding after that time: keep everyone out and call 112 again if nobody has arrived yet. If it has stopped: do not light the boiler, stove or cooker until a gas engineer has checked them. Evidence to keep: the time the alarm stopped and who cleared you to go back in.
- Use the Test button silence only the way FireAngel describes
Who: you, and only after ventilating and evacuating if the cause of the alarm is unknown. How: the manual explains that pressing the Test button silences the sounder for 5 minutes, but it will not silence if more than 150 ppm has been detected and it sounds again if CO rises above 180 ppm. Result that matters: not mistaking a silenced alarm for a sign that the danger is over. If the alarm refuses to silence: CO is high, so leave and wait for help outdoors. If it goes quiet and starts again a little later: carbon monoxide is still present, leave the home again. Evidence to keep: whether you silenced it, at what time and whether it came back on.
- When you come home, look for a double red flash
Who: you, if you were out when the alarm went off. How: FireAngel says that if nobody silences it, the alarm sounds until CO drops below 50 ppm and then the red light flashes twice every 40 seconds for 7 days to let you know. Result that matters: learning that dangerous CO was present while you were away even though nothing can be heard now. If you see that double red flash: ventilate, keep fuel-burning appliances off and call a gas engineer. If a family member feels unwell on entering: go back out and call 112. Evidence to keep: a short video of the light pattern and the date you found it.

What a technician must be able to justify
Technician visit
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Emergency services for suspected poisoning
What they doEmergency services treat anyone with symptoms and, where needed, send the fire service to measure CO and ventilate the property.
They must show youthe CO reading they took indoors and in which rooms.
In writingthe incident number, the time of attendance and whether you were allowed back in.
FireAngel Technical Support enquiry
What they doIf after the incident the alarm neither sounds nor flashes red when you hold Test, FireAngel Technical Support assesses a replacement.
They must show youthe alarm batch number and the date printed next to REPLACE BY.
In writingthe support case number and what FireAngel decided about the warranty.
Check of every fuel-burning appliance
What they doA qualified gas engineer inspects the boiler, heaters, cooker, stoves, chimneys and flues before you use them again.
They must show youthe flue gas analysis of each appliance and the draught of chimneys and flues.
In writingwhich appliance produced the CO, the repair carried out and whether each one is safe to use.

What it means
Get everyone outside, call 112 or your local emergency number if anyone has symptoms, and do not go back in until emergency services allow it. In the FireAngel FA6813 user manual (section 3), a loud signal of four repeated chirps at 85 dB with a red flash at the same time means the alarm has measured dangerous CO levels; it reacts faster the higher the concentration and sounds within 3 minutes at 300 ppm or more. The sound alone never proves that a part has failed: always treat it as a real emergency. Other FireAngel models may signal differently.
Warnings and stop conditions
- Criticalsource verified
Never remove the batteries or cover the FA6813 to stop the noise: the manual only allows silencing with the Test button, and above 150 ppm even that does not work.

- Highsource verified
A quiet sounder does not prove the air is safe: keep fuel-burning appliances off until a gas engineer has inspected them.
