9. Operation and Testing
operation
The alarm is operating once it is activated and testing is complete. When products of combustion (smoke) are sensed, the
unit sounds a loud alarm with voice messages. See Sections 1 and 2 for alarm signal descriptions.
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 Section 2: 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 Section 12: Permanently Disable Alarm / Discharge Battery to determine how to prepare the unit
for shipment or disposal.

Ambient light sensing
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 Test/Hush 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.
