Siren Sensors, RFID Vehicle Triggers & Access Parts
SOS is the original manufacturer of the Siren-Operated Sensor - used nationwide by emergency response teams to trigger automatic gate access using standard “Yelp” sirens. Built to respond in seconds without any remotes or codes, SOS sensors are trusted by fire departments, police agencies, and municipalities for mission-critical access.
Elite offers the full range of SOS products, including the flagship siren sensors, RFID vehicle detection systems, and accessories. Their RFID solutions offer secure, vehicle-specific access using windshield-mounted transponders - ideal for first responders, utility fleets, or community vehicles requiring rapid, automated entry. Also available are replacement parts, warning decals, and rugged weatherproof housings.
Whether you're specifying a fire lane, retrofitting a gated community, or adding multi-agency emergency access to a perimeter gate, SOS provides field-tested, zero-failure entry technology backed by decades of deployment.
