CARBON MONOXIDE ALARM
The following information is highlights from the folder provided by the alarm
manufacturer. The folder, with more detailed information, is contained in your Owners’
Packet.
Test detector immediately following installation and weekly for proper operation by
pushing the test button until the YELLOW L.E.D. lights and a short beep is heard
(approximately three seconds). Release the button. The detector will then test itself for
proper operation. At completion of the self-test, the alarm will sound and both L.E.D.s
will light for 3/4 of a second. The detector then resumes normal operation.
NORMAL OPERATION
In normal operation the detector will flash the RED L.E.D. once every 30 seconds.
WARNING CONDITION
If the COSTAR senses a low level of CO The YELLOW L.E.D. will light and the detector
will beep every three seconds warning that CO is present. The area should immediately
be ventilated. A concentration of 60 PPM within 67 minutes will cause the warning
condition. Pushing the test button will silence the warning.
signal but the YELLOW L.E.D. will stay on. After two hours the warning signal will
sound again if the CO source has not been eliminated. If the condition persists there
is a possibility that it may cause the unit to enter alarm condition (below). If this occurs
pushing the reset button will silence the alarm for 30 minutes.
ALARM CONDITION
If the COSTAR senses unsafe levels of CO, the RED L.E.D. will light up and the alarm
will sound. The alarm condition will be signified by a repetitive alarm-sounding pattern
of approximately 4.5 seconds on 1.5 second off. Immediate evacuation is required.
Pushing the test button will silence the alarm once for approximately 4 minutes.
After approximately 4 minutes the alarm will once again sound until the unsafe CO
concentration is removed.
FAULT CONDITION
Periodically the detector’s measurement circuit is tested. If an error is detected, the
detector will sound twice and the YELLOW L.E.D. will flash twice every 30 seconds.
This is an indication of circuit malfunction and that the detector requires immediate
servicing.
MAINTENANCE
Battery Replacement:
If tamper resistant pin has been used, refer to “tamper resistant locking pin” for removal
instructions.
To replace the battery remove the detector from the mounting plate by rotating the
detector in the direction of the “OFF” arrow on the cover.
The Model 9L-1 CO Detector uses one (1) 9-volt battery. The CO DETECTOR is
powered by a 9V alkaline battery. A fresh battery should last for one year under normal
operating conditions. This detector has a low battery monitor circuit which will cause
the detector to “chirp” and the red LED to flash approximately every 30-40 seconds
for a minimum of seven (7) days when the battery gets low. Replace the battery when
this condition occurs. USE ONLY THE FOLLOWING 9 VOLT BATTERIES FOR CO
DETECTOR REPLACEMENT
Alkaline type: EVEREADY522; DURACELL MN1604; GOLD PEAK 1604A
Lithium type: ULTRALIFE U9VL
NOTE: REGULAR TESTING IS RECOMMENDED.
