The SOS Gate SOS 14 is a siren-operated emergency access device designed to provide first responders with automatic access through compatible powered gates. The sensor listens locally for an approaching emergency vehicle siren and, when the appropriate siren pattern is detected, activates a dry-contact relay connected to the gate operator's open input.
The SOS 14 is the current replacement for the previous SOS 12. It retains the basic siren-operated emergency access function of the SOS 12 while updating the enclosure, microphone location, electronics, mounting arrangement, and wire-entry provisions.
For customers replacing an existing SOS 12 Siren-Operated Sensor, the SOS 14 is the current replacement model. The operating concept remains the same: an emergency vehicle approaches the secured gate, activates the appropriate siren, and the SOS sensor provides an open command to the compatible gate operator.
The SOS 14 should not be treated as a physically identical SOS 12 enclosure. Before replacing an older unit, verify the existing power source, dry-contact gate input, wire routing, mounting holes, conduit arrangement, and installation location.
The SOS 14 detects emergency vehicle sirens at the gate and provides a dry-contact relay output to the gate operator. It connects to the operator's normally open and common input terminals on systems designed to accept a dry-contact open command.
The SOS 14 does not supply motor power and does not directly operate the gate motor. It functions as an access-control input that tells the gate operator to open. The gate operator remains responsible for controlling gate movement and all required safety and entrapment-protection functions.
The SOS 14 is compatible with automatic gate operators that accept a dry-contact open command. The typical connection is made to a normally open and common gate operator input.
Compatibility should be determined by the operator control board and its available inputs, not simply by the gate operator brand. LiftMaster, Nice, Apollo, HySecurity, DoorKing, Viking, FAAC, Linear, and other operators have different control board generations and input arrangements. Verify the operator manual or control board diagram before connecting the SOS 14.

Package contents can change with manufacturer revisions. Verify current packaging if a specific accessory or mounting component is required for the job.
The manufacturer specifies surface mounting in an outdoor location with the microphone/sound opening unobstructed and positioned toward the roadway approach. The enclosure is designed to fit on a 4-inch post and supports rear or bottom wire entry.
The mounting location is important. Avoid locations where structures, landscaping, machinery noise, or other obstructions could interfere with siren detection. Detection sensitivity should be adjusted and the completed installation should be function-tested according to the manufacturer's instructions.
The SOS 14 requires a compatible gate operator input. It provides a dry-contact relay command and is intended to connect to a normally open/common input that causes the operator to open the gate.
Do not connect the SOS 14 directly to a gate motor, high-voltage motor circuit, safety-device circuit, photo-eye input, safety-edge input, or other terminal that is not specifically intended to receive the required dry-contact open command.
If the correct gate operator input, voltage, wiring, or emergency-access configuration is unclear, have the installation completed or verified by a qualified gate or access-control technician.
The SOS 14 is an emergency-access input device and does not replace the gate operator's required entrapment-protection devices, monitored photo eyes, safety edges, emergency controls, or other UL 325 safety equipment. Never bypass required gate safety devices to install an emergency access sensor.
Emergency-access requirements can vary by municipality, fire authority, property type, and jurisdiction. Confirm local fire, building, and emergency-access requirements with the authority having jurisdiction before relying on any single access method.
Yes. The SOS 14 is the current replacement for the previous SOS 12 Siren-Operated Sensor. Existing SOS 12 installations should still be checked for power, wiring, mounting, conduit, and gate operator input compatibility before replacement.
The SOS 14 is designed for automatic gate operators that accept a dry-contact open command. It typically connects to the operator's normally open and common input terminals.
No. The SOS 14 provides a dry-contact command signal to the gate operator. It does not drive or supply power directly to the gate motor.
The SOS 14 operates from 9-24 VDC or 9-16 VAC. Verify the available power source and operator wiring before installation.
No. The unit should be surface mounted where its microphone opening remains unobstructed and faces the roadway approach. The SOS 14 is designed to fit on a 4-inch post and supports rear or bottom wire entry.
Yes. The SOS 14 uses a NEMA 4 outdoor-rated enclosure and has a specified operating temperature range of -4 F to 140 F (-20 C to 60 C).
Yes. The SOS 14 provides configurable relay timing that can be set for momentary operation or extended gate hold-open operation for up to one hour, depending on the required installation configuration.
Verify the existing power source, normally open/common gate input, wiring, mounting location, conduit arrangement, wire entry, and available space. The SOS 14 replaces the SOS 12 functionally but uses an updated physical design.
