General Description
The FAP42T's 130˚ dispersion angle effectively reduces the number of
loudspeakers necessary to achieve coverage in distributed systems with
low ceilings.
The loudspeaker component matches the performance of the legendary
Atlas Sound Strategy FA Series. High quality construction 4" coaxial cone
type driver includes a 1" voice coil and polypropylene cone with a butyl
rubber surround. The 19mm coaxially mounted tweeter is constructed
of PEI. A high sensitivity level means less power may be required to
achieve the desired SPL. This loudspeaker is factory assembled in an
optimally tuned & ported deep drawn enclosure and includes a specially
designed 16 Watt low saturation 70.7V / 100V transformer. A convenient
front mounted selector switch allows tap selection without the need to
remove the speaker from the ceiling. This switch also includes a trans-
former bypass setting for 8Ω direct coupled operation.
Mounting Accessories
Mounting is simplified with Strategy style "Dog Leg" tabs that allow
easy installation into drop tile or drywall ceilings with provided tile bridge
assembly. The tile bridge consists of two "V" shaped formed mounting
rails and a C-Ring assembly. The C-Ring can be attached to the rails with
the screws provided to extend support to the T-Bar grid in suspended
ceiling applications. Multiple hole locations are provided to allow the
C-Ring to be positioned to the outer edge the tile if necessary.
For existing dry-wall applications the tile bridge C-Ring and support rails
can be inserted into the hole cut for the FAP42T. For easy positioning the
"V" shaped support rails match the shape of the C-Ring tabs for easy
maneuvering and location when working "blindly" above the deck
A uniquely designed "easy access" input panel on the side of the enclo-
sure allows for "thru" conduit runs using flexible or rigid conduit. Below
this cover resides a detachable Phoenix style locking four-pole connec-
tor which provides for easy daisy chain wiring to other full range 70.7V
loudspeakers or Atlas Sound FASUB subwoofer. The package includes an
attractive press-fit grille which nicely matches contemporary architecture.
For new construction drywall ceiling applications, the optional FAP42-TR
trim ring is available. This unit provides a marked location for drywall
installers to cut around essentially reserving the desired location in the
ceiling until final installation of FAP42T. Mounting holes are provided to
accommodate 16" or 24" OC stud / joist mounting.
A support ring is also provided on the top of the FAP42T enclosure to
facilitate an auxiliary support cable.
NOTE: IT IS MANDATORY THAT THIS SECONDARY SUPPORT
BE UTILIZED IN DROP CEILINGS FOR SAFETY AND SEISMIC
CONSIDERATIONS).
