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

Smoke alarm

Aico: if the alarms are sounding there may be a fire — evacuate, and if in doubt always assume the fire is real (homeowner FAQ). The Ei650 leaflet: check doors for heat before opening, crawl low under heavy smoke, get out and meet at your prearranged place, call the Fire Brigade from a neighbour’s house or a mobile phone giving your name and address, and never re-enter a burning house.

From Homeowner FAQs — Why is my alarm beeping? and Battery Powered Smoke Alarms Ei650 Series — instruction leaflet (Rev 6).

Carbon monoxide alarm

Aico: a sounding CO alarm means carbon monoxide is likely to be present. Turn off any gas appliances, open windows and doors, and leave the property; ring the emergency number of your gas or fuel supplier; do not go back in until the alarm has stopped.

What Aico says to do about this signal

  1. The leaflet lists this among the diagnostic modes used at maintenance to see whether there has been an alarm; it gives no separate instruction. An alarm you did not hear is still an alarm: the emergency instruction above is Aico’s.

From Battery Powered Smoke Alarms Ei650 Series — instruction leaflet (Rev 6). If your alarm’s pattern is not exactly this, check the manual for your model: Aico models do not all use the same signals.
