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 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
In low light ambient conditions, the green LED ring fades to off, and then blinks approx every 60 seconds. This unit sam-
ples 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.
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.
