10. 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 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.

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.
