Fire/Police/EMS/911 responders, open gates with Siren's "yelp"
in 2.5 seconds (all sirens in 4.5), hands free.... No codes
to remember or keys to lose. A reminder decal on gate tells
responder to hold siren on for swift entry. Mandate that your
gated communities be uniformly 911 "respondable".
Thousands now in use! Compatible with all gate operators.
Protects property, loved ones. Pass the good word. Homeowners
who are gone when the fire breaks out will be glad you did.
The SOS II now has it all in a single small
package. Yelp (decible time), Fast - or Slow to Trigger, Release
or Latch Relay, Momentary or 15 Minute Relay. SOS-II is proximity
adjustable, and has switchable safety options built into the
circuit board. SOS sensors are designed for non-directional
use at gated compounds. Audio range: the to on hundred feet
(dial adjustable). Thses units are mounted an all weather
enclosure (3x6x2 inches). Full instructions are sent with
the SOS, including an all weather "Fire, EMS, Police,
911, hold sirens, YELP for SOS entry" decal to place
at the controlled site. A demo "yelp" tape is also
sent with all orders. |

Basic Concept
The Siren-Operated
Sensor (SOS) is designed to respond swiftly to the "YELP"
mode of all standard sirens. A reminder decal is provided
to be placed on each entry gate. Responders already own their
siren. This device represents Public Safety without spending
Public Funds. The SOS is the nation's most widely used Uniform
Emergency Gate Access.
Installation and Testing
Since all gate operators use low voltage for their electronic
controls, this source can easily be used to power the mini
requirements of the SOS. A demonstration "Yelp"
audio tape is provided, along with instructions, with each
SOS sold.
Technical Specifications
The Frequency response of the Siren-Operated Sensor is from
200Hz to 10KHz. The SOS relies on a time-varying frequency
input in this range. This, plus proprietary techniques,
allows the microprocessor to respond to the siren's "YELP"
with a dry relay closure in 2.5 seconds.
• The SOS uses an onmidirectional microphone. Alignment
is not necessary.
•SOS Range is adjustable - 5 to 50 feet or more. A
potentiometer located on the PC board allows this
•The SOS is not affected by ambient light.
•The surface-mount PC board is installed in a 3"x5"x2"
rain-tight enclosure.
•Weight is approximately 7 oz.
•The power requirements are 9 to 30 Volts AC/DC with
approximately a 2 mA draw.
•Momentary relay activation, or switchable to a 15-minute
hold, or to a latch.
Warranty
The SOS has a five-year warranty when installed according
to the manufacturer's specifications.
