10. Operation And Testing
Operation
The alarm is operating once it is activated and
testing is complete (see “TESTING” below).
When products of combustion (smoke or CO)
are sensed, the unit sounds a loud alarm with
voice messages. See Sections 1 and 2 for alarm signal descriptions. In high levels of CO, the unit will go into
alarm in a shorter period of time than at low levels of CO.
Testing
Test your alarm weekly by pressing and releasing the test button quickly. A quick beep will confirm the button
has been pushed followed by the test sequence. See Other Alarm Visual and Audible Indicators table. The alarm
and voice (and any interconnected units) will sound if the electronic circuitry, horn, speaker, and battery are
working. If the alarm or voice does not sound, or gives erratic or low volume sound, the unit must be replaced.
WARNING: DUE TO THE LOUDNESS OF THE ALARM, ALWAYS STAND ABOUT 2.5 FEET AWAY
FROM THE UNIT OR USE EAR PROTECTION WHEN TESTING.
WARNING: DO NOT USE AN OPEN FLAME TO TEST YOUR ALARM, YOU COULD DAMAGE THE
ALARM OR IGNITE COMBUSTIBLE MATERIALS AND START A STRUCTURE FIRE.
Chirping
When End of Unit Life or Low Battery chirping begins, you can temporarily silence these chirps by pressing
the Test/Hush® button. See Troubleshooting Guide.
WARNING: REPLACE UNIT AS SOON AS POSSIBLE WHEN IN END OF UNIT LIFE MODE.
