Ubiquiti USL-Entry-3-US | SuperLink Entry Sensor, Door/Window, 2km, 6-Year Battery

Q: What does the USL-Entry-3-US include?
A: This listing includes 3 x UniFi SuperLink Entry Sensors, each with its corresponding magnet, adhesive, and screw mounting hardware. A SuperLink Gateway is required for operation and is sold separately.

Q: What wireless protocol does the UniFi Entry Sensor use?
A: It uses Ubiquiti's proprietary SuperLink protocol operating at 915.6–927.6 MHz (US frequency). SuperLink is purpose-built for low-power, long-range sensor communication with end-to-end encryption and secure OTA updates — distinct from standard Wi-Fi or Zigbee.

Q: How far can the sensor communicate from the gateway?
A: The USL-Entry supports a maximum wireless range of up to 2 km (1.2 miles), making it suitable for large commercial buildings, warehouses, campuses, and facilities where sensors may be located far from centralised infrastructure.

Q: How long does the battery last, and what type is required?
A: Each sensor runs on a single CR123A lithium battery with a rated battery life of up to 6 years, significantly reducing replacement frequency compared to standard AA or AAA-based sensors. This makes the USL-Entry ideal for large-scale deployments.

Q: Which UniFi application manages these sensors?
A: The USL-Entry sensors are managed through UniFi Protect, Ubiquiti's unified physical security platform. They integrate alongside UniFi cameras and access control devices for centralised event monitoring and alerting via UniFi OS.

Q: Can I purchase the UniFi SuperLink Entry Sensor 3-Pack in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian-owned B2B IT hardware reseller operating since 2001. You can order the USL-Entry-3-US directly from our website with local support and competitive pricing for business customers.
