12. 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).
Indoor Air Quality
This device is designed to monitor levels of temperature, relative humidity and total volatile organic compounds
(TVOC) – chemicals in the air that can impact your health. Visit www.epa.org for more information on VOCs. Relative
Humidity % (RH) refers to the percentage of water vapor in the air at a given temperature. Ideal RH for living con-
ditions is usually recommended at 30% - 60%. The parameters listed below are based on a typical average, climate
controlled residence. When conditions in the residence move outside of the limits shown in the table, an alert is sent
to your mobile device. You can also check the status of your indoor air quality using the Kidde app, after your alarm is
registered with the app.

noTe: The indoor air quality monitor may not react to some particles and its readings may be different from that of
other air quality measuring products and instruments.
It's helpful to understand the difference between temporary high readings and persistent high readings. A one-
time event might create a temporarily high reading but is not a cause for concern in the long term. However, if you
consistently get high levels of poor indoor air quality in a room, then you should take steps to improve ventilation or
air circulation in the area of the device. Please refer to the threshold ranges in the app to know what readings are
considered high.
It is important when comparing readings between different devices that the comparison is truly under the same con-
ditions. TVOC concentrations can vary throughout the home, so the placement of the devices in the house can have
an impact on their readings. If the devices are not right beside each other, or one of the devices is closer to a vent or
fan, this could impact the difference.
