Cut the opening in the ceiling tile a minimum of 0.25 in. larger than the outer
diameter of the sprinkler head or trim ring/escutcheon (whichever is larger). This
enables the tile to fall from the ceiling grid without becoming entangled with the
sprinkler or interfering with its operation.
or
Use a 0.030 in. thick Signature style panel backed by a mineral ber ceiling panel
at each sprinkler penetration. This holds the tile in place and keeps it insulated,
preventing it from interfering with sprinkler operation.
Never use a restraining-type trim ring/escutcheon at a sprinkler penetration without an
appropriately sized tile opening or mineral ber ceiling panel backer.
Drop-Out Ceiling Panels Beneath Sprinklers
All Ceilume ceiling panels are approved for installation beneath re sprinklers in Light Hazard and
Ordinary Hazard Group I occupancies. When exposed to heat from a developing re, these drop-out
ceiling panels soften, distort, and fall from the ceiling grid. Heat from the growing re activates the
sprinkler which, unimpeded by the panels, controls or extinguishes the re.
All Ceilume ceiling panels are listed and approved for use beneath Standard Response (SR) sprinkler
systems rated with an activation temperature of 165°F or above, where allowed by local safety
authorities.
Additionally, Ceilume’s 0.013 in. thick Feather-Light styles are listed and approved for use beneath
Quick Response (QR) and Standard Response (SR) sprinkler systems rated with an activation
temperature of 155°F or above, where allowed by local safety authorities.
Please note: Grid tape and strips have not been tested for use in drop-out installations, though there
is no mechanical reason that their use, when installed properly, would affect the panels’ ability to drop
from your grid.
Consult with your local building and re ofcials to make sure that your intended use will
conform with the appropriate local codes.
Painting
All of our ceiling tiles and strips can be painted before or after installation.
• Be sure that everything is clean and dry before painting.
