While on AC power, in the event of a CO incident, the alarm pattern will
continue to repeat as long as CO is present.
NOTE: Pressing the Test/Reset button tests the functions of the alarm’s
internal components, circuitry and micro-computer.
YOU DO NOT NEED TO PRESS THE TEST BUTTON TO TAKE A CO
READING.
CO readings are automatically shown on the alarm’s digital
display. If the alarm indicates zero (0), then no measurable amount of
CO has been sensed by the alarm within the past 15 seconds.
How to Know If Your Alarm is Malfunctioning

of these signal groups (depending upon the type of malfunction that
occurs):
Malfunction Signal Group 1 - Component Failure
– An intermittent “chirping” alarm will sound every 30 seconds.
– An “Err” message will appear on the digital display,
– The yellow LED will light continuously, and

OR,
Malfunction Signal Group 2 - Microprocessor Failure
– The alarm will sound continuously,
– The digital display will be blank,
– The yellow LED will light continuously
