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
E
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.
