How to Test Your CO Alarm
You should test the alarm once a week, following the directions listed
below. If at any time you test the alarm and it does not perform as
described, have it replaced immediately.
Turn to “
How to know if your alarm is malfunctioning
” section for a
description of the characteristics of a malfunctioning alarm and what
you should do if a malfunction occurs.
Observe the alarm weekly to make sure the green power light is lit con-
tinuously indicating normal operation.
If the green light is not on or the unit does not respond to pressing the
Test button, unplug the alarm for three minutes, and then plug it in
again. This will clear the alarm for restart. If the unit still does not
respond, your alarm may be malfunctioning.
To test the alarm, press the Test/Reset button. If the unit is operating
properly, you should notice the following:
The unit will beep and the yellow LED will flash acknowledging the but-
ton was pressed and the self test has started. After a short pause, you
should then hear 8 seconds of quick beeps. It will then return to moni-
toring for CO.
Familiarize yourself and household members with the alarm pattern
described above a CO event.
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 taken every 15 seconds automatically.
How to Know If Your Alarm is Malfunctioning
Your alarm performs an internal self-diagnosis every 15 seconds to
make sure that it is functioning properly. The alarm is designed to alert
you in the unusual event of a malfunction.
If the alarm malfunctions
In the rare event that your alarm malfunctions, it will alert you with one
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.
– The yellow LED will light continuously, and
– The unit does not respond to pressing the Test button.
