Overview
The Ubiquiti USL-ENTRY-3 is a three-pack of UniFi SuperLink Entry Sensors designed to monitor whether doors and windows are open or closed. Each sensor communicates wirelessly using Ubiquiti's proprietary SuperLink technology and integrates with the UniFi Protect application suite.
The sensors are battery powered and designed for wireless installation on doors, windows, and other suitable opening points. Ubiquiti specifies battery life of up to six years, reducing the need for frequent battery replacement.
Entry Detection
The sensor uses a two-piece design consisting of the sensor device and a separate magnet. The two components are positioned together when the monitored door or window is closed. Opening the monitored entry separates the sensor and magnet, allowing the system to detect the change in open/closed status.
SuperLink Connectivity
The USL-ENTRY-3 uses Ubiquiti's proprietary SuperLink wireless protocol for communication. A compatible SuperLink Gateway is required for the sensor to communicate with the UniFi Protect ecosystem.
Installation
The sensor supports both adhesive and screw mounting. Its wireless, battery-powered design avoids the need to run a dedicated power cable to the monitored door or window. The sensor and magnet should be installed so their relative position changes when the monitored opening is opened.
Key Features
- Three wireless UniFi SuperLink entry sensors in one pack
- Monitors door and window open/closed status
- Up to six years of specified battery life
- Proprietary SuperLink wireless connectivity
- Adhesive and screw mounting options
Applications
The USL-ENTRY-3 can be deployed across multiple doors or windows as part of a UniFi Protect installation. Typical deployment points include exterior doors, interior doors, windows, cabinets, and other openings where open/closed status needs to be monitored.
DC Supplies Product Note
The USL-ENTRY-3 requires a compatible SuperLink Gateway for operation with UniFi Protect. The three sensors are individually installed at the monitored openings, so gateway placement and SuperLink wireless coverage should be considered when planning the installation.
