12. 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 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 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.
Ambient Light Sensing
In low light ambient conditions, the green LED ring fades to off, and then blinks approx every 60 seconds.
This unit samples the ambient light conditions of the alarm’s location
and, if possible, determines a Night / Day cycle. A valid Night / Day cycle
will delay unit chirps during the night until the next Day cycle begins.
Chirping
When chirping begins during the next Day cycle, you can temporarily silence End of Unit Life or Network Error chirps
by pressing the button. Low Battery chirps cannot be silenced.
If a valid Night / Day cycle has not been established because the unit is located in either a constantly dark or lighted
location, the chirps mentioned above will not be delayed at night. Moving the unit to a different location might allow
the unit to determine a valid Night / Day cycle.
WARNING: REPLACE UNIT AS SOON AS POSSIBLE WHEN IN END OF UNIT LIFE OR LOW BATTERY MODE.
