2. Carbon Monoxide Alarm: What To Do When the Alarm Sounds
The carbon monoxide (CO) alarm pattern is four quick beeps with voice "Warning! Carbon
Monoxide" repeating every 5 seconds. The red LED blinks in time with the alarm pattern. On
DC power only, after 4 mins, the alarm pattern and voice will only occur every 60 sec.

1) Operate the Test/hush button. nOTE: pressing the button on the initiating alarm unit (green
LED flashing every second) will silence the alarm notification, including all interconnected units.
if the unit goes into alarm mode again within six minutes, it is sensing high levels of CO which
can quickly become a dangerous situation.
2) Call your emergency services (fire Department or 911). EMErgEnCy phOnE #:___________
3) immediately move to fresh air — outdoors or by an open door / window. Do a head count to
check that all persons are accounted for. alert small children in the home as well as anyone else
that might have difficulty recognizing the importance of the alarm sounding or that might have
difficulty leaving the area without help. Do not reenter the premises or move away from the open
door/window until the emergency services responders have arrived, the premises have been aired
out, and your alarm remains in its normal condition.
4) after following steps 1-3, if the alarm reactivates within a 24 hour period, repeat steps 1-3 and
call a qualified appliance technician to investigate sources of CO from fuel burning equipment and
appliances, and to inspect for proper operation of equipment.
if problems are identified during this inspection, have the equipment serviced immediately.
note any combustion equipment not inspected by the technician and consult the manufactur-
er's instructions, or contact the manufacturer directly for more information about CO safety and
the equipment. Make sure that motor vehicles are not, or have not been, operating in a garage
attached or adjacent to the residence. never restart the source of a CO problem until it has been
corrected. never ignore the sound of the alarm!
nOTE: see section rECOgniZing nuisanCE aLarMs, for nuisance alarm situations.
