Applications
Communicate voice and electronic signals clearly in industrial,
commercial, recreational, transportation and service facilities with Atlas
Sound’s UL-Listed APF Series loudspeakers. These environment-resistant
units are engineered to meet life safety and general communication
requirements and are ideal for indoor or outdoor applications where highintelligibility paging or intercommunication are necessary.
Description
APF Series voice control loudspeakers are 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.
APF Series loudspeakers 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 facilitate 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.
Models include 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.
A built-in, 5 mfd capacitor is provided on Model APF-15TUC for line
supervision. Model APF-15TU is not equipped with a capacitor. All units
are finished in grey baked epoxy.
All models meet or exceed 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.
Models are also California State Fire Marshal Listed. Models with special
modifications to meet other safety authorities are available. Contact
factory.
Accessories
BX-3A Vandal resistant cover plate for armored cable
and conduit connection. Constructed of cast
aluminum.

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.
