APPLICATIONS
Atlas Sound’s UL Listed AP Series loudspeakers are surface-mount-
ing, high-efficiency units for life safety and communication system
applications. When used with compatible control equipment, they pro-
vide high-intelligibility voice reproduction and signal transmission for
indoor or outdoor emergency alarm, protective signaling and intercom
system installations.
GENERAL DESCRIPTION
Atlas Sound AP Series Omni-Purpose loudspeakers are equipped
with a compression driver providing up to 15 watts RMS power
handling capability, superior intelligibility and dispersion to achieve
maximum sound projection and penetration.
Weather-resistant metal construction and re-entrant acoustic path
assure protection against water, humidity, vermin and corrosion. The
Omni-Purpose®mounting bracket allows directional sound dispersion
via vertical and horizontal positioning. Provisions are also included for
surface or strap mounting to pillars and I-beams.
All models include a built-in 25/70.7V Vari-Tap®transformer featuring
a screw-driver adjustable, 7-position watt/impedance selection switch.
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 AP-15TUC(R) for line
supervision. Model AP-15TU is not equipped with a capacitor.
All models meet or exceed the UL Listed standards for audible signal
appliances and are capable of operating within an ambient temp.
range of 66°C (150°F) to -35°C (-30°F). Models comply with UL
Standard 1480—Speakers for Fire Protective Signaling Systems and
California State Fire Marshal (Title 19). Models with special modifica-
tions to meet New York City MEA (Calendar no. 57-74-SA) and UL
Canada are also available as standard product. Contact Factory.
