9.0 SELF TEST SEQUENCE
When power is applied to the Model 452 CO Detector, a self-test routine begins.
The test checks for functionality of the critical components such as the CO sensor,
temperature sensor, and the integrity of the total CO Detector system.
The test sequence is as follows:
• Alert buzzer beeps twice.
• Green light flashes twice.
• Remote Amber Alert light flashes once.
• Amber Alert light flashes twice.
• Alert buzzer beeps once.
• Green light ON steady.
• Remote Amber Alert light flashes once.
The remote alert light will flash once before the detector mounted Amber alert
light flashes and once after the steady green light in the above sequence. Then
the external Amber light will remain OFF until there is another CO alert or until a
failure of the unit occurs.
10.0 PILOT RESPONSE TO IN-FLIGHT CO ALARM
If the CO Detector aural and visual alarms go off in flight, press the TEST/RESET
button.
If the alarm continues to operate by showing a blinking Amber light on the CO
Detector and the remote Amber light stays on:
• Shut off the heater, air conditioning or any other opening to the engine
compartment.
• Open a fresh air source immediately.
• Don't smoke.
• Use 100% oxygen, if possible.
• Land as soon as conditions permit.
•
Be sure the source of the contamination is corrected before further flight
NOTE: Blinking Amber light on the unit itself and the remote Amber light
will stay on until the CO level goes below 50 PPM.
DO not recycle the unit through the circuit breaker, as there is a three-
minute delay for the CO sensor to stabilize at each startup.
