Ubiquiti USL-GlassBreak UniFi Protect Glass Break Sensor
Overview
The Ubiquiti USL-GlassBreak is a battery-powered glass break sensor designed for UniFi Protect deployments. It combines advanced glass break detection with an integrated PIR sensor and communicates through Ubiquiti's proprietary SuperLink wireless technology. :contentReference[oaicite:1]{index=1}
The sensor is designed for monitoring compatible glass in security applications and supports a maximum SuperLink range of up to 2 km (1.2 miles). A SuperLink Gateway is required for operation. :contentReference[oaicite:2]{index=2}
Glass Break Detection
The USL-GlassBreak includes a built-in microphone for acoustic glass break detection and supports plate, tempered, obscured, laminated, coated, and wired glass. Supported glass sizes range from 280 x 356 mm (11 x 14 inches) to 1067 x 1626 mm (42 x 64 inches). :contentReference[oaicite:3]{index=3}
Supported glass thicknesses are 2.4 mm (3/32 inch), 3.2 mm (1/8 inch), 4.8 mm (3/16 inch), and 6.4 mm (1/4 inch). These specifications should be checked against the glass being monitored before installation. :contentReference[oaicite:4]{index=4}
SuperLink Connectivity
The sensor uses proprietary SuperLink connectivity for communication with the UniFi Protect environment. The US version operates at 915.6–927.6 MHz, with a maximum SuperLink transmit power of 14 dBm and a maximum specified range of 2 km (1.2 miles). :contentReference[oaicite:5]{index=5}
UniFi Protect is the specified application suite, with support through the UniFi Protect web application and UniFi Protect iOS and Android mobile applications. :contentReference[oaicite:6]{index=6}
Installation and Hardware
The USL-GlassBreak supports both adhesive and screw mounting. The hardware includes a function button, factory reset control, tamper switch, status LED, and signal LED. The enclosure and mount are made from polycarbonate. :contentReference[oaicite:7]{index=7}
The sensor operates from two CR123A lithium batteries and has a specified battery life of up to three years. Maximum power consumption is 0.2 W at a supported voltage of 3 V. :contentReference[oaicite:8]{index=8}
