6. Push and hold the test button on each unit for at least five
seconds, or until all the devices produce an alarm. If all the
units do not produce an alarm, refer to the Troubleshooting
Guide at the end of the User Guide.
CAUTION: Due to the loudness of the alarm,
always stand an arm's length away from the unit
when testing.
7. Install the alarm in accordance with the User Guide as
described in the Where to Mount the Alarm section and repeat
Step 6. Since wireless communication can be interrupted by a
number of factors, you must test your alarms weekly to ensure
proper communication between alarms.
If your Kidde smoke alarms enter alarm mode, first check for a
fire. If a fire does not exist and the test buttons have not been
activated on any of the units, it is likely that you are receiving
interference from a similar system nearby. In this case, repeat
the above steps and select a different DIP switch pattern. Be
sure to disconnect power and remove the batteries before
changing the switch positions.
The interconnect system should not exceed the NFPA
interconnect limit of 12 smoke alarms.
Kidde battery-powered alarms CAN ONLY BE interconnected
with other Kidde wireless alarms. Refer to the User Guide
supplied with your Kidde product for lists of interconnect
compatible models, brands and devices.
To help identify the date to replace the alarm, a space has
been designated on the product label affixed to the back of the
alarm. Write the "replace by date" (ten years from initial power
up) in permanent marker on the label (see Alarm Replacement
section for additional information).
