8. Installation Instructions
Kidde alarms are not designed, agency tested or certied for recessed mounting and should not be installed
in this manner. Recessed mounting impedes smoke entry into the smoke chamber, which may prevent the
alarm from sounding in a timely manner. This could endanger the lives of occupants in the residence. Kidde
alarms are designed, tested and certied for wall (if applicable) and ceiling surface mount only. Without
agency research, we have no re test data to support that alarms will perform as required when installed in a
recessed manner. Accordingly, we do not recommend, approve or advise mounting Kidde alarms in recessed
congurations.
This apparatus should be installed by a competent individual.
