Step 6 – Connect a Secondary Support Line to Seismic Tab – A tab is provided on
the back of each speaker for connection to a independent secondary support point.
Some construction codes require using this secondary support point, which requires
connecting a support line to a separate secure support point. Consult construction
codes in your region.
!
Control Contractor ceiling speakers can generate substantial vibration . It is
HIGHLY RECOMMENDED to use the seismic tab as a secondary support
point in case the ceiling tile or structure breaks.
