Background
Model 551 is a CO Detector that Displays CO Level between 10PPM
(Parts per Million) to 999PPM. The detector consists of one Red
button that is used to test and silence the alarm. Every time
the unit is turned on or the reset button is pressed in a non
alarm condition, the system will test the entire circuit for
integrity. If the unit alarms, the unit can be silenced by
pressing the
Red
reset button. The lights and display continue
displaying till CO goes below 10 PPM.
Installation
Install Aero-551 per CO Guardian installation drawing number
01-551-01-Rev. A (Or later revision) for hardware and wiring
diagram installation.
SELF TEST SEQUENCE AT STARTUP:
When you power up the Aero-551, you will notice the following test
sequence:
The screen will show the word “CO Guardian” along with two short beeps
followed by a third one and the wording “CO LEVEL NORMAL” will
display. Internally in the background, the system will check the
sensor for 30 seconds and all internal components. If any components
fail, the display will show the word “Failed” and the unit must be
returned for repair.
CARBON MONOXIDE LEVEL INDICATION:
DISPLAY: CO LEVEL
Aero 551 can detect Carbon Monoxide from as low as 10 PPM. Aero 551 will
trigger an alarm for CO long before the pilot/passengers can be affected by
exposure to CO.
The effect of CO level on the human body is linked to the duration of
exposure to CO. Our units are designed to set off CO alarms in progressively
shorter durations as the concentration of CO increases. The intention is to
prevent a false alarm when the CO level poses no danger, but at the same
time ensure full protection when the level starts becoming dangerous.
