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. Aico’s homeowner advice: contact your installer or an Expert Installer. Its trade page lists what they will check — the connections, gaps where cables enter the base letting cold air in, and electrical interference from something on the same circuit, such as a fluorescent starter or a central-heating pump.

From Homeowner FAQs — Why is my alarm beeping? and Basic Alarm Fault Finding. If your alarm’s pattern is not exactly this, check the manual for your model: Aico models do not all use the same signals.

Fault on other brands

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