NORMAL OPERATION:
In normal operation, the alarm will flash the red LED indicator once every 30 seconds. Alarm is
powered and active.
ALARM CONDITION:
If the alarm senses unsafe levels of CO, the red LED indicator will light up and the alarm will sound. The
alarm condition will be signified by a repetitive alarm sounding pattern of 4 short beeps followed by 5
seconds of silence. Immediate evacuation is required.
TROUBLE CONDITION:
Periodically, the alarm's measurement circuit is tested. If an error is detected, the alarm will sound a
single beep and the red LED indicator will flash twice every 30 seconds. This is an indication of circuit
malfunction and that the alarm requires immediate servicing.
END-OF-SERVICE LIFE:
The red LED indicator will flash twice and the alarm will beep twice every 30 seconds.

MAINTENANCE
BATTERY REPLACEMENT:
IF THE TAMPER RESISTANT PIN HAS BEEN USED, REFER TO "TAMPER RESISTANT LOCKING PIN"
FOR REMOVAL INSTRUCTIONS
(See Figure 5).
To replace the battery, remove the alarm from the mounting plate by rotating the alarm in the direction
of the "OFF" arrow on the cover (See Figure 4, Step D).
The CO alarm is powered by a 9V Alkaline battery. A fresh battery should last for one year under
normal operating conditions. This alarm has a low battery monitor circuit which will cause the alarm to
"chirp" and the red LED indicator to flash approximately every 30-40 seconds for a minimum of 7 days
when the battery gets low. Replace the battery when this condition occurs.
USE ONLY THE
FOLLOWING 9 VOLT BATTERIES FOR CO ALARM REPLACEMENT
Alkaline type:
EVEREADY 522; DURACELL MN1604; GOLD PEAK 1604AU
Lithium type:
ULTRALIFE U9VL
NOTE: REGULAR TESTING IS RECOMMENDED.
WARNING! USE ONLY THE BATTERIES SPECIFIED. USE OF DIFFERENT BATTERIES MAY HAVE A
DETRIMENTAL EFFECT ON THE CO ALARM. THE CONSTANT EXPOSURES TO HIGH OR LOW
TEMPERATURES OR HIGH HUMIDITY MAY REDUCE BATTERY LIFE.
CLEANING YOUR ALARM:
To clean your alarm, remove it from the mounting plate as outlined in the beginning of this section.
You can clean the interior of your alarm by using your vacuum cleaner hose and vacuuming through
the openings around the perimeter of the alarm.
WARNING:
The outside can be wiped with a damp cloth. Do not use any household cleaning agents,
ammonia based cleaners, paints, varnishes or any other chemical on or near your alarm.
AFTER
CLEANING, REINSTALL YOUR ALARM. TEST YOUR ALARM BY USING THE TEST BUTTON.
TESTING YOUR ALARM:
Test alarm weekly for proper operation by pushing the test button for approximately three seconds
until a short beep is heard . Release the button. The alarm will then test itself for proper operation, i.e.
an alarm pattern of 4 beeps with the red LED on, a 5 second quiet period and another 4 beeps with the
red LED on. Then, the unit resets with a final red LED flash. The alarm then resumes normal operation.
