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 high-intelligibility paging or intercommunication
are necessary.

GENERAL 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 5

1

⁄2" deep opening or
recessed enclosure. Units will facilitate Atlas Sound L20 Series
grilles, enclosures and mounting rings (refer to SL2-1372). 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 temp.
range of 66°C (150°F) to -35°C (-30°F).The all-metal, environment­resistant 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.

CONNECTION: 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.
