SWIFT HI-TECH ENTRY ("YELP" response is 2.5 seconds... 4.5 other sirens.)

ABOUT:

The SOS-YDT version stands for YELP/DECIBEL/TIME. It's programmed to respond to emergency vehicle sirens' "YELP" and open the gate in 2.5 seconds. If the responder is not using the "YELP", yet the decibel level remains high for an additional 2 seconds, the YDT will trigger the gate to open. This version will therefore respond to the "wail" or any consistent sound producing 4.5 seconds of high decibel. The SOS-YDT is proximity adjustable, and has switch able safety options built into the circuit board.

BAISIC CONCEPT:

The Siren-Operated Sensor (SOS) is designed to respond swiftly to the "YELP" mode of all standard emergency vehicle 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. At this writing (2001), the SOS is the nation's most widely used Uniform Emergency Gate Access.

INSTALLATION & TESTING:

Since all gate operators use 12 to 24 Volts AC or DC 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.

ADVANTAGES:

Wider operating voltage range. The SOS now operates on 9 to 30 Volts, AC or DC.
Reverse polarity operation. Even if the power supply is connected backwards the SOS will operate normally.
When power is applied, the LED will blink slowly amber.
The amber LED turns off and the green LED activates once a siren has been detected and the relay closes.
The amber LED is on steadily only when the received sound is above the threshold sensitivity setting and the SOS is trying to discern a siren. If a sound does not have a high enough frequency to be a siren it is rejected.
Higher selectivity. The SOS is now more selective about what sounds constitute a siren.
The screwless wire connector is fast and easier to install.
Double relay closures for use on dual (in and out) gates providing wider fire equip. entry.
Smaller size (4.7 x 3.13) and lower power consumption, yet more user selectable options:
- Siren pattern recognition is 'Yelp' Decibel Time concurrently.
- User selectable 'fast or slow' detection response to any one of the chosen siren options.
- User selectable relay action. Relay duration can be set to momentary, 15 minute or latch until reset.
- Latch mode can be cleared by pressing the reset switch, or removal of power temporarily.
All SOS products have a 5 year limited warranty if installation instructions are followed.
It is the gate owner's responsibility to periodically verify SOS functionality.

TECHNICAL SPECS:

The Frequency response of the SOS Siren-Operated Sensor is from 200 Hz to 10 KHz. 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 omni directional microphone. Alignment is not necessary.
- Range of the SOS is adjustable - 5 to 50 feet or more. A potentiometer located on the PC board provides this adjustability. The SOS is not affected by ambient light.
- The PC board for the SOS is mounted in a 3.2" x 6.5" x 3.2" rain-tight enclosure.
- Weight is approximately 10 ounces.
- The power requirements for the SOS are 12/24 Volts AC/DC with approximately 2.5 mA draw. Momentary relay activation or switch able to a 10-minute hold.
