Description

The USL-Relay is a compact SuperLink I/O relay module designed for seamless integration of third-party sensors and signaling devices within the UniFi Protect physical security ecosystem. With wireless SuperLink connectivity reaching up to 2 km line of sight, it eliminates the need for network cabling between relay points and security infrastructure. Dual dry contact relay outputs support both AC and DC circuits up to 240V AC / 48V DC at 10A per port, while dual dry contact signal inputs feature integrated 5V TVS protection — making it ideal for access control panels, alarm systems, door strikes, and industrial signaling devices.

The USL-Relay accepts a wide 12–48V DC input voltage range, compatible with common security power supplies and battery backup systems. Flexible mounting options — adhesive, wall screw, or DIN rail — suit installation in control cabinets, server rooms, and space-constrained locations. Each input and output is independently configurable via the UniFi Protect web, iOS, and Android apps. Note: a SuperLink Gateway is required for operation. Available now at iptrading.com.au — competitive prices and local support.

FAQs

Q: What is the USL-Relay and what does it do?
A: The USL-Relay is a compact wireless I/O relay module that integrates third-party sensors, door strikes, alarm panels, and signaling devices into the UniFi Protect security platform. It uses Ubiquiti's proprietary SuperLink wireless protocol, so no network cabling is required between the relay and the rest of your security infrastructure.

Q: Do I need any additional hardware to use the USL-Relay?
A: Yes — a SuperLink Gateway is required to operate the USL-Relay. The gateway bridges the SuperLink wireless network to your UniFi Protect system. Without a gateway, the relay cannot communicate with UniFi Protect.

Q: What types of devices can be connected to the USL-Relay?
A: The relay outputs (O1/COM/O2) support dry contact loads including door strikes, electric locks, sirens, and indicator lights running on 12–48V DC or 12–240V AC at up to 10A per port. The signal inputs (I1/I2) accept dry contact sensors such as PIR motion detectors, door/window contacts, and alarm panel outputs. It is compatible with resistive, capacitive, and inductive loads.

Q: How far can the USL-Relay communicate wirelessly?
A: The USL-Relay uses SuperLink wireless technology with a maximum range of 2 km (1.2 miles) under line-of-sight conditions. This makes it suitable for deployments across large facilities, car parks, or between buildings where cabling is impractical.

Q: How is the USL-Relay managed and configured?
A: The USL-Relay is managed natively through the UniFi Protect application, available on web browsers, iOS, and Android. Each input and output is independently configurable, allowing custom automation rules and event triggers to be set without third-party software.

Q: Can I purchase the USL-Relay in Australia, and is local support available?
A: Yes — the USL-Relay is available now at iptrading.com.au. IP Trading is an Australian B2B IT hardware reseller offering competitive pricing and local support. Contact us for volume pricing, compatibility advice, or assistance with your UniFi Protect deployment.
