5. WHAT TO DO IF YOUR CO ALARM SOUNDS
Carbon Monoxide Alarm Procedure
WARNING! When this alarm sounds it indicates the presence of CO which can kill you. Based on
recommenda.ons from EN 50292, follow these steps if alarm sounds (4 loud audible pulses followed
by a pausefor 5 seconds):
1) Keep calm and open all doors and windows. Turn off all fuel-burning appliances if possible.
Note: it is possible that outdoor condi.ons could influence domes.c CO alarms (bad traffic
pollu.on in cold weather, for example). In these circumstances, the level of indoor CO might
actually increase when doors and windows are opened.
2) If the alarm con.nues to sound, even a er being reset (where appropriate), then evacuate the
premises, aler.ng other occupants to the risk. Leave doors and windows open. Do not re-enter
the premises.
3) Get medical help for anyone suffering the effects of CO poisoning, and advise that CO inhala.on
is suspected.
4) Call Gas Emergency Services: 0800 111 999, or your local Gas Safe Registered Engineer:
Engineer.
Never restart the source of a CO problem un.l it has been corrected. Never ignore the sound of the
alarm! Pressing the test/reset bu/on will silence the alarm. If the CO condi.on that caused the alert
con.nues, the alarm will reac.vate. If the unit alarms again within six minutes, it is sensing high
levels of CO which can quickly become a dangerous situa.on.
