11. Operation and Testing
OPERATION
The alarm is operating once it is activated and testing is complete. 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 voice prompts that will inform
you of the upcoming 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. See Permanently Disable Alarm / Discharge Battery section to determine how to prepare the
unit for shipment or disposal.
WARNING: DUE TO THE LOUDNESS OF THE ALARM, ALWAYS STAND ABOUT 0.7 M (2.5 FT) 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.
SMOKE/CO ALARM MEMORY
If a unit experiences a smoke or CO alarm event, then the condition clears and the unit stops alarming, the
unit will give a visual (LED) indicator that a previous alarm has occurred within the last hour. See the Other
Alarm Visual and Audible Indicators table.
CO ALARM SENSOR RESPONSE TIMES
At 70 PPM, the unit must alarm within 60-240 minutes.
At 150 PPM, the unit must alarm within 10-50 minutes.
At 400 PPM, the unit must alarm within 4-15 minutes.
