The A.C.A. Allertor 125 is a powerful, rotating, directional
siren with a unified design that is both compact and
weatherproof. The output of 126 decibels at 100 feet is
radiated to an effective 70 DB range of 4500 feet, thus giving
a total circular coverage of 2.2 square miles per siren. (Federal
CD Guide, March 1964.)
The single 10 HP motor produces the sound through direct
drive rotor-stator design and also rotates the entire assembly at
3.5 RPM through a direct drive worm and spur gear
combination.
Model CD1-103 Size B is a two-signal siren
Model CD-107 Size 3B3 produces two or three signals
The standardized signals are as follows:
1 - ALERT, a dual tone sustained tone scale signal
2 - ATTACK - TAKE COVER, a dual tone wailing slowly
up and down tone scale signal

GENERAL INFORMATION

SPECIFICATIONS

5 ft. high
15' below horizontal
30' wide horizontally
Semi-enclosed, induction
motor. High torque. Direct
coupled to rotor and gear
reducer. Single phase
available as special.
3A - FIRE, a dual tone wail of different timing than the
attack signal
3B - FIRE, a dual tone yelp or rapid down tone scale signal
with a pause between each tone blast.
All signals are precisely controlled by a solid state integrated
circuit master control device or a radio decoder-timer.
When specified, the electrical controls associated directly with
the siren are prewired and contained inside a weatherproof
metal enclosure, which may be mounted in any convenient
location. Electrical installation is simple and straightforward.
A variety of signal sources may be employed to initiate
operation of a siren or siren system including -
1 - Direct mechanical switch
2 - Telephone relay system
3 - Radio relay system
4 - Program timer
5 - Any combination of the above
