If it is sounding a full alarm instead: the maker’s emergency instruction

Smoke alarm

FireAngel: never ignore any alarm. If your smoke or heat alarm goes off and you are not absolutely certain of the source, get everyone out of the house immediately — sleeping children first — and call the fire and rescue service without delay, however small the fire (FireAngel’s FAQ: evacuate immediately and call 999).

From FA6611, FA6615 & FA6620 Optical Smoke Alarm & FA6720 Heat Alarm — User Manual and Fire & Smoke Alarm FAQs.

Carbon monoxide alarm

FireAngel: if the CO alarm goes off with four loud beeps, immediately open doors and windows, stop using any appliances and switch them off, and leave the building taking the CO alarm with you. If it stops after 10 minutes in fresh air, you may have a CO leak: call your gas supplier or the national gas emergency line on 0800 111 999 and wait for instructions. Do not go back in until it has been declared safe.

What FireAngel says to do about this signal

  1. FA6611 and FA6615 (2 × AA): replace the batteries, then test the alarm.
  2. FA6620 and FA6720 (sealed battery): replace the whole alarm within 30 days; if it is under warranty, contact FireAngel Technical Support.
  3. Sleep Easy: pressing Test silences the low-battery beep for 8 hours; FireAngel says to act the next day.

From FA6611, FA6615 & FA6620 Optical Smoke Alarm & FA6720 Heat Alarm — User Manual. If your alarm’s pattern is not exactly this, check the manual for your model: FireAngel models do not all use the same signals.

The same state sounds and looks different on each make — which is why a chirp pattern cannot be read without the brand.
