For Gates, Doors, Parking Arms, Barriers or Roll-up Doors to open for emergency responders
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.
