WEEKLY TESTING
Push and hold the T
est/Silence button until you hear an acknowledge chirp and
a loud alarm sounds — 4 beeps, pause, 4 beeps. This sequence should last for
10 seconds. If the Alarm ever fails to test pr
operly, replace it immediately. If the
Alarm is not working properly, refer to “Limited Warranty”.
•
If the Alarm ever fails to test properly, replace it immediately.
Products under warranty may be returned to the manufacturer for
replacement. See “Limited Warranty” at the end of this manual.
• DO NOT stand close to the Alarm when the horn is sounding.
Exposur
e at close range may be harmful to your hearing. When
testing, step away when horn starts sounding.
•
NEVER use vehicle exhaust! Exhaust may cause permanent damage
and voids your warranty.
REGULAR MAINTENANCE
T
o keep the CO Alarm working properly:
• Test it every week as described in “Weekly Testing.”
•
Vacuum the CO Alarm cover at least once a month, using the soft brush
attachment. Never use water, cleaners, or solvents, since they may damage
the unit. T
est the Alarm again after vacuuming.
•
Replace the battery immediately when you see/hear the “Low Battery
W
arning”.
The Low (or Missing) Batter
y Warning (CO5120PDBN):
The horn will “chirp” once a minute and the word “bat” will flash on and off
on the display
.
REPLACING THE BATTERY
Choosing a r
eplacement battery:
This unit r
equires one standard 9V alkaline
battery. The following alkaline batteries are acceptable as replacements:
Duracell #MN1604 or MX1604; Eveready “Energizer” 522. These replacement
batteries ar
e commonly available at local retail stores.
Use only the alkaline or lithium replacement batteries listed. The unit may not
operate properly with other batteries. Never use rechargeable batteries since
they may not provide a constant charge.
DO NOT spray cleaning chemicals or insect sprays directly on or near
the CO Alarm. DO NOT paint over the CO Alarm. Doing so may cause
permanent damage.
• Household cleaners, aerosol chemicals and other contaminants can
affect the sensor. When using any of these materials near the CO Alarm,
make sure the room is well ventilated.
• If your home is being fumigated, unplug the unit temporarily and put it
where it will not be exposed to chemicals or fumes. When fumigation is
complete and all traces of fumes clear, plug the unit back in and retest it.
IF YOUR CO ALARM SOUNDS
Actuation of your CO Alar
m 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 T
est/Silence button to silence the alarm.
2.
Call your emergency services, fire department or 911. Write down the
number of your local emer
gency service here:
________________________________________________________________
3.
Immediately move to fresh air—outdoors or by an open door or window.
Do a head count to check that all persons ar
e accounted for. Do not re-
enter the premises, or move away from the open door or window until the
emer
gency services responder has arrived, the premises have been aired
out, and your CO Alarm r
emains in its normal condition.
4.
After following steps 1-3, if your CO Alarm reactivates within a 24-hour period,
r
epeat steps 1-3 and call a qualified appliance technician to investigate for
sour
ces of CO from fuel-burning equipment and appliances, and inspect for
proper operation of this 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
ers’
instructions, or contact the manufacturers directly, for more information about
CO safety and this equipment. Make sur
e that motor vehicles are not, and
have not, been operating in an attached garage or adjacent to the r
esidence.

Alarms have various limitations. See "General Limitations of CO Alarms"
for details.
USING THE SILENCE FEATURES
NEVER disconnect the power to your CO Alarm to silence the horn—
use the silence feature. Disconnecting the CO Alarm removes your
pr
otection! See previous page for details on responding to an alarm.
The Silence Feature is intended to temporarily silence your CO Alarm’s alarm
horn while you correct the problem—it will not correct a CO problem. While the
Alarm is silenced, it will continue to monitor the air for CO.
When CO reaches
alarm level, the unit will sound— repeating horn pattern: 4 beeps, a pause, 4
beeps, etc. Press and hold the Test/Silence button until the horn is silent.
The Silence cycle will last approximately 4 minutes.
To silence an interconnected series of Alarms, you must press the Test/
Silence button on the initiating alarm (the unit with the flashing red light).
If you press the Test/Silence on any other Alarm, it will only silence that unit,
not the whole interconnected series.
NOTE: After the 4-minute silence cycle, the CO Alarm re-evaluates present CO
levels and responds accordingly. If CO levels remain potentially dangerous—or
start rising higher—the horn will start sounding again.
While the CO Alarm is silenced:
If the CO Alarm...is silent for only 4 minutes, then starts sounding loudly—4
beeps, then a pause, 4 beeps, then a pause. Red light (LED) continues flashing...
This means...CO levels are still potentially dangerous.
If the CO Alarm...remains silent....
This means...unit has returned to normal operation.
SILENCING THE LOW BATTERY WARNING
This silence feature can temporarily quiet the low battery warning “chirp” for
up to 8 hours if AC
power is present. Press the Test/Silence button on the
alarm cover
. Once the low battery war
ning “chirp” silence featur
e is activated,
the unit continues to flash the red light once a minute for 8 hours. After 8
hours, the low battery “chirp” will resume. Replace the battery as soon as
possible,
to maintain protection in the event of a power outage.
LATCHING FEATURES
Alarm Latch is activated after an Alarm is exposed to alarm levels of carbon
monoxide. This featur
e will only work with AC power. After CO levels drop
below alarm levels, the Red LED will begin to flash On for 2 seconds and Off
for 2 seconds. It will continue to flash or “latch” until you clear it by testing
the Alarm.
This feature helps emergency responders, investigators, or service technicians
identify which unit(s) in your home were exposed to alarm levels of carbon
monoxide. This can help investigators pinpoint the sour
ce of CO.
Interconnected Alarms. Latching Alarm Indicator shows which Alarm(s) in
the series wer
e exposed to alarm levels of carbon monoxide.
The Latching Alarm Indicator stays ON until you clear it, so it can alert you to
a CO Alarm that occurred while you were away from home, even though CO
present in the air has dropped below alarm levels.
Low Batter
y Latch
is activated when the Alarm is in the "low battery
condition". When this occurs, the red LED flashes 4 seconds On/2 seconds
Off. This feature is designed to help you identify which Alarm needs to have
the battery replaced. Although, the Alarm will sound the low battery chirp
approximately once every minute, sometimes during the initial stages of "low
battery", the Alarm will chirp in gr
eater intervals than one minute, sometimes
up to several hours, until the battery reaches a steady low battery level. This
innovative feature eliminates the frustration of waiting for and/or identifying
which unit is chirping.
WHAT YOU NEED TO KNOW ABOUT CO
WHAT IS CO?
CO is an invisible, odorless, tasteless gas produced when fossil fuels do not
burn completely, or are exposed to heat (usually fire). Electrical appliances
typically do not produce CO.
These fuels include: W
ood, coal, charcoal, oil, natural gas, gasoline, kerosene,
and propane.
Common appliances are often sources of CO. If they are not properly main-
tained, are improperly ventilated, or malfunction, CO levels can rise quickly.
CO is a r
eal danger now that homes ar
e mor
e ener
gy ef
ficient. “Air
-tight”
homes with added insulation, sealed windows, and other weatherpr
oofing
can “trap” CO inside.
