Ubiquiti UniFi Protect Siren (USL-SIREN) - Siren, White

The Ubiquiti UniFi Protect Siren (USL-SIREN) provides audible and visual alerts when triggered. It integrates into a wider surveillance system by communicating directly with the UniFi Protect controller. The unit uses wireless protocols rather than network cabling to receive commands and requires no Ethernet connection. A built-in siren and emergency-style lighting provide localized warnings. The device remains in standby mode until activated by the management software.

The housing features an aluminium alloy base and polycarbonate components for durability in commercial settings. The standard white finish allows the unit to blend into most indoor and outdoor environments. The included plate enables mounting on walls or ceilings. With an IP56 rating, the unit is dust- and water-resistant and suitable for outdoor use. Configuration is managed via a web interface. As it does not support Power over Ethernet (PoE), the unit requires a local power supply at the mounting site.
