Overview
The Ubiquiti USL-ENTRY-US is a UniFi SuperLink Entry Sensor designed to monitor whether a door or window is open or closed. It uses a reed switch and communicates wirelessly through Ubiquiti SuperLink technology for long-range, low-power operation.
Connectivity
The sensor uses Ubiquiti's proprietary SuperLink wireless connection. The US version operates in the 915.6–927.6 MHz frequency range and provides a maximum specified SuperLink range of up to 2 km (1.2 miles).
Power and Battery
The sensor is powered by a CR123A lithium battery and operates from a 3 V supply. Ubiquiti specifies battery life of up to six years, making the sensor suitable for long-term wireless door and window monitoring.
Installation
The USL-ENTRY-US supports both adhesive and screw mounting. The sensor and its separate magnet are positioned together on the monitored opening so that the integrated reed switch can detect the open or closed state.
UniFi Protect Integration
The Entry Sensor is managed through UniFi Protect. It can be monitored using the UniFi Protect web application and mobile applications. A compatible SuperLink Gateway is required for SuperLink connectivity.
Key Features
- Door and window open/closed monitoring
- SuperLink wireless connectivity with up to 2 km specified range
- Up to six years of battery life using a CR123A lithium battery
- Adhesive and screw mounting options
- Integrated reed switch and tamper detection
Applications
The USL-ENTRY-US is intended for wireless monitoring of doors and windows in residential and commercial environments using a UniFi Protect installation.
DC Supplies Product Note
The sensor requires a compatible SuperLink Gateway to communicate with the UniFi Protect system. When planning an installation, account for the gateway requirement in addition to the individual entry sensor.
