Since 1992 the original Siren Operated Sensor (SOS) has been used to open residential, commercial, airport, government and military
gates during an emergency. SOS is currently used throughout North, South and Central America as well as in Europe. If you need your
gates, doors, parking arms, barriers or roll-up doors to open for emergency responders, then you need an SOS installed on each of these
devices today!
Once the “Yelp” siren has been recognized for 3 seconds a trigger is sent to open the gate. The SOS is the most cost effective way for
emergency responders to access your home or business without stopping or leaving their vehicle to enter a code or use a key.
The reliability of the SOS Emergency Access System has made it mandatory in many communities throughout the world. Making your gate
siren activated is a big step to saving lives and property.

Technical Requirements of the SOS:
Voltage: DC 9 to 30 volts or AC 9 to 16 volts
Amp draw: 0.1 mA (milliamp) when listening and when activated has a 25 mA draw during the trigger
Wire gauge: 18-22 AWG (not included)
Temperature: The SOS remains functional in temperatures ranging from -30 to 120 degrees Fahrenheit.
Potentiometer: You can easily adjust the sensitivity of the unit with the potentiometer dial. The necessary decibel level varies by the
unit’s sensitivity setting:
• Sensitivity set at 0: The unit will not trigger at any decibel level
• Sensitivity set at 3: The unit will trigger at 125 decibels
• Sensitivity set at 5: The unit will trigger at 105 decibels
• Sensitivity set at 7: The unit will trigger at 95 decibels
• Sensitivity set at 9: The unit will trigger at 80 decibels
Programming: The SOS is equipped with four switches to customize the sound that will open the gate and the length of time the gate
remains open after being triggered by an emergency vehicle. You can Keep the gate open for just one vehicle to enter,
hold for 15 minutes or if you prefer, latch it open until the reset button is pushed.
Reset Button: SOS units have two reset buttons that perform the same function. One on the exterior of the enclosure and one on the
inside of the enclosure on the circuit board.
Siren Test: The SOS includes a CD recording of an emergency responder “yelp” siren so you can test the unit and adjust the
sensitivity settings to your preference or you can download an MP3 file from www.sosgate.com. It is recommended
that you get a live siren to test your unit twice a year.
Reflective Sign: Each unit ordered comes with a 4” X 5” or 8” x 10” sign which clearly tells emergency responders your gate is protected
by SOS. It is your choice which size sign you get.
