In a series of interconnected Alarms, you must test
each Alarm separately by pressing and holding the
test button. Make sure all units alarm when each
one is tested.
If any unit in the series does not alarm during testing,
TURN OFF POWER and recheck connections. If it does
not alarm when you restore power, replace it immediately.
ACTIVATING THE BATTERY BACK-UP
Activate the battery back-up by remov-
ing the “Pull to Activate Battery Back-
Up” tab. You do not need to open the
battery compartment and reposition
the battery during installation.
DO NOT remove the battery activation tab until AC
power is turned on to conserve battery power.
Test the alarm. Press and hold the test button on the
cover until the alarm sounds:
4 beeps, pause, 4 beeps, pause.
CHAPTER 3: IF YOUR CO ALARM SOUNDS
Actuation of your CO Alarm indicates the presence
of carbon monoxide (CO) which can kill you. When
your CO Alarm sounds, you must not ignore it!
IF THE ALARM SOUNDS:
1. Operate the Test/Silence button to silence the alarm.
2. Call your emergency services, fire department
or 911. Write down the number of your local
emergency service here:

3. Immediately move (everyone) to fresh air—out-
doors or by an open door or window. Do a head
count to check that all persons are accounted for.
Do not re-enter the premises, or move away from
the open door or window until the emergency
services responder has arrived, the premises have
been aired out, and your CO Alarm remains in its
normal condition.
(Do not remove or disconnect the alarm!)
4. After following steps 1-3, if your CO Alarm reacti-
vates within a 24-hour period, repeat steps 1-3
and call a qualified appliance technician to
investigate for sources of CO from fuel-burning
equipment and appliances, and inspect for proper
operation of this equipment. If problems are iden-
tified during this inspection have the equipment
serviced immediately. Note any combustion equip-
ment not inspected by the technician, and consult
the manufacturers’ instructions, or contact the
manufacturers directly, for more information about
CO safety and this equipment. Make sure that
motor vehicles are not, and have not, been operat-
ing in an attached garage or adjacent to the resi-
dence. Write down the number of a qualified appli-
ance technician here:
