APF-15TU-USA
UL Listed 15 Watt Flange Mounting Voice Control Loudspeaker
General Description
The APF-15TU-USA voice control loudspeaker is equipped with a
compression driver to provide up to 15 Watts of continuous power
handling, superior intelligibility and audio conversion efficiency for
maximum sound projection and penetration.
The APF-15TU-USA may be flush mounted or recessed directly
into interior/exterior walls or ceilings. Recessed installation may be
accomplished by mounting loudspeakers into a 51⁄2" deep opening
or recessed enclosure. Units will work with Atlas Sound L20 Series
grilles, enclosures and mounting rings (refer to ATS003855). Accessory
mounting kits Model MK-2 or FAMT-6 can be used to mount
loudspeakers into 8" diameter baffles.
The unit includes a built-in 25/70.7V Vari-Tap® transformer featuring a
screw-driver adjustable, 7-position watt/impedance selection switch.
Magnet assembly is equipped with self-aligning field replaceable
diaphragm. Wiring terminals are protected with a vandal-resistant
adapter cover for control equipment utilizing cable or conduit.
The unit is finished in grey baked epoxy. The APF-15TU-USA meets
or exceeds UL Standard 1480 for Fire Protective Loudspeakers and
are capable of operating within an ambient temperature range of 70˚C
(158˚F) to -40˚C (-40˚F). The all-metal, environment-resistant construction
and re-entrant acoustic path assure protection against water, humidity,
vermin, physical abuse, and corrosion. The unit is also California State
Fire Marshal Listed. Additionally, the APF-15TU-USA complies with Buy
American Act standards.

CAUTION: Amplifier output line connection is made
to the screw terminals which are designed with wire
retainers for insured reliability. Input terminals are
numbered (#1 and #2) to maintain system phasing
(#2 is the positive terminal). The wide and narrow slots
adjacent to #1 and #2 are used for cable strain relief.
