ROTATING DIRECTIONAL
Here are some of the reasons
for the Allertor's popularity
A single 10 HP motor produces the sound
through direct drive rotor stator assembly
and rotates the sound beam at 3.5 RPM.
Maximum sound penetration is achieved by
directing the sound in a beam 10° above
horizontal to 15o below horizontal.
Direct coupling of all sound producing and
rotational components means greatly in-
creased reliability and freedom from break-
downs. No drive belts to slip.
Completely enclosed in durable fiberglass
to eliminate rusting and painting problems.
Unified design allows effective mounting on
pole, roof or parapet.
Dual tone, non harmonic models available
in 523 -698 hertz or other special frequencies
and with two or three signal capabilities.
Ali sirens are tested before shipment.
Guaranteed 3 years on siren parts and one
year on electrical parts.
The decibel rating of the ACA equipment dis-
cussed herein is based on testing done by inde-
pendent laboratories under ideal conditions.
Test results may vary depending on various
factors, including weather conditions.

Leader in its class. It exceeds the output rating re-

U. S. Government installations and a multitude of
local municipal applications.
