Alarm Condition; Fault Condition - Airstream LAND YACHT MOTORHOME Owner's Manual

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.
Warning:
BATTERIES MAY HAVE A DETRIMENTAL EFFECT ON THE CO DETECTOR.
CLEANING YOUR DETECTOR:
To clean your detector remove it from the mounting bracket as outlined in the beginning of this section.
You can clean the interior of your detector by using your vacuum cleaner hose and vacuuming through the
openings around the perimeter of the detector. The outside can be wiped with a damp cloth.
AFTER CLEANING, REINSTALL YOUR DETECTOR. TEST YOUR DETECTOR BY USING
THE TEST BUTTON.
Test detector 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.
