• Test the alarm once a week. If the alarm ever fails to test correctly, have it replaced immediately.
If the alarm is not working properly, it cannot alert you to a problem.
• This alarm must have battery power to operate. If the battery is dead, the alarm cannot operate.
The sealed battery cannot be replaced.
• This product is intended for use in ordinary indoor locations or family living units. It is not designed
to measure CO levels in compliance with Occupational Safety and Health Administration (OSHA)
commercial or industrial standards. Individuals with medical conditions which may make them
more sensitive to carbon monoxide may consider using warning devices which provide audible
and visual signals for carbon monoxide concentrations under 30 ppm. For additional information
on carbon monoxide and your medical condition, contact your physician.
NORMAL OPERATION: In normal operation, the alarm will blink the red LED on once approximately
every 2 minutes. On digital display models, the screen will be blank.
CO ALARM: The alarm signal is 4 beeps, 5 second pause, repeat. The red LED blinks on in sync
with the cycle of 4 beeps. The screen will indicate the current CO readings if higher than approx.
50 ppm on digital display models.
Although this alarm will not automatically display levels below approx. 50 ppm, it will detect and
store these readings in memory. In typical ambient surroundings, CO concentrations may range up
to 50 ppm, which may be an indication of a temporary or intermittent condition. Sometimes such a
condition may start out as low-level leaks, but can develop into harmful CO concentrations. If this
happens, the CO alarm will detect the dangerous level and alarm which should be treated as an
EMERGENCY. DO NOT ignore high concentration readings above 50 ppm or a CO alarm
NUISANCE ALARM / CO SILENCE: If there is no hazard present and the alarm is still sounding,
activate the silence feature by pressing and releasing the Test/Silence button on the alarm. Silence
mode will last for approx. 5 minutes with the red LED blinking once approx. every 10 seconds. Verify
the alarm is mounted in the correct location (see User's Manual, "AVOID THESE LOCATIONS"
section). Reset alarm as instructed below. And the red LED will blink ON approximately every
2 seconds.
TROUBLE / SERVICE ALARM: Periodically, the alarm measurement circuit is tested. If an error
is detected, the alarm will sound 3 chirps approx. every 60 seconds and the red LED will blink ON
approximately every 2 seconds. Reset the alarm as instructed below. If this does not clear the
problem, deactivate the alarm (see ALARM DEACTIVATION section in the User's Manual). Replace
alarm immediately. Alarm will not detect CO.
END-OF-SERVICE LIFE ALARM: When it is time to replace your alarm, which is in approximately
10 years of operation from initial power up, the alarm will sound 2 chirps approx. every 60 seconds.
Deactivate alarm (see ALARM DEACTIVATION section in User's Manual). Replace alarm immediately.
Alarm will not detect CO.
RESET THE PEAK CO MEMORY (digital display models only): If there was a previous peak CO
level recorded, press and hold the Reset/Peak button for 10 seconds and release. The screen will
display "000" when the button is released indicating the peak CO level is reset and then the screen
will be blank.
RESET THE CO SILENCE AND TROUBLE / SERVICE SIGNALS: Press and hold the RESET/PEAK
OR RESET button for 10 seconds and release. This will reset the silence and trouble/service signals.
WHAT TO DO IF CARBON MONOXIDE IS DETECTED:
If you hear the alarm horn sound 4 beeps, a 5 second pause (and then repeat),
carbon monoxide has been detected. Evacuate everyone from the building.
Actuation of your CO Alarm indicates the presence of carbon monoxide (CO), which can kill you.
In other words, when your CO Alarm sounds, you must not ignore it!
Some individuals are more sensitive to CO than others, including people with cardiac or respiratory
problems, infants, unborn babies, pregnant mothers or elderly people can be more quickly and
severely affected by CO. Members of sensitive populations should consult their doctors for advice
on taking additional precautions.
