Ubiquiti USL-SIREN 110 dB All-weather SuperLink Siren
Overview
The Ubiquiti USL-SIREN is a battery-powered outdoor siren for Ubiquiti UniFi Protect deployments requiring remote audible alerts without line-voltage infrastructure. At 110 dB output in an IP56-rated aluminum and polycarbonate enclosure, it handles rain, dust, and temperature swings from −30 to 50° C. The USL-SIREN mounts flush or surface-mounted on walls and ceilings, making it practical for perimeter security, parking structures, equipment yards, and entry vestibules where wired speakers are impractical or cost-prohibitive. Four CR123A batteries deliver roughly 5W nominal consumption, enabling rapid deployment in seasonal facilities, leased spaces, or phased security rollouts. NDAA-compliant for federal and institutional procurement.
Compatibility
The USL-SIREN pairs exclusively with UniFi Protect controllers via SuperLink wireless protocol (915.6–927.6 MHz US, 865.1–869.5 MHz EU). Trigger and arm through the UniFi Protect web interface or native iOS and Android applications. Does not integrate with third-party VMS platforms or non-UniFi access-control systems. Compatible with all UniFi Protect camera and sensor networks sharing the same controller.
Installation Notes
Mounting plate included for wall or ceiling installation. SuperLink max range of 2 km (1.2 mi) line-of-sight assumes minimal obstruction—plan radio propagation around building materials and terrain. Verify operating frequency compliance (915.6–927.6 MHz US vs. 865.1–869.5 MHz EU) before deployment in regulated markets. Battery replacement interval depends on alert frequency and test cycles; no battery monitoring is provided in the field. The single power button supports manual override and factory reset during commissioning. Tamper switch and R/G/B/W status LEDs aid rapid troubleshooting.
