SOS III (Siren Operated Sensor)

Siren Operated Sensor

The Siren Operated Sensor (SOS) is used to open Residential, Commercial, Airport, Government and Military Gates during an emergency. The reliability of the SOS Emergency Access System has made it mandatory in many communities throughout the country. SOS is the most cost effective way for emergency responders to access your homes and buisnesses without stopping or leaving their vehicle to enter a code or use a key. SOS is compatible with all gate operators. Because SOS specializes in sound sensors, triggers can be customized to respond to individual frequencies.

**Includes "Yelp Demo CD"

The SOS III now has it all in a single small package.

•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.
