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, or after returning from a vacation or absence, by pressing and releasing the button
quickly. A quick beep will confirm the button has been pushed followed by voice prompts that will inform you
of the upcoming test sequence. See Other Alarm Visual and Audible Indicators table. The alarm and voice 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 1 METER 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.
