110dB Alarm Output

The USL-Siren delivers a powerful 110dB audible alarm designed to provide a clear security warning across residential, commercial and other protected environments. The integrated buzzer works alongside visual emergency lighting to provide both audible and visible alarm notification.

Integrated Emergency LED Lighting

An integrated RGBW light ring provides emergency visual signalling in addition to the audible siren. Dedicated system and status LEDs provide further device feedback, enabling the siren to form part of a coordinated UniFi Protect alarm deployment.

Long-Range SuperLink Connectivity

The siren communicates using Ubiquiti's proprietary SuperLink wireless technology, providing a manufacturer-rated range of up to 2km (1.2mi). This allows the USL-Siren to be deployed at substantial distances from compatible SuperLink infrastructure, subject to installation conditions. A compatible SuperLink Gateway is required.

Battery or DC Power

The USL-Siren supports flexible powering through four CR123A batteries or a 12–24V DC input. This allows the siren to be deployed wirelessly where convenient or connected to a suitable DC power source for fixed installations. Maximum power consumption is rated at 5W.

All-Weather IP56 Construction

An IP56-rated enclosure provides protection for all-weather installations. Aluminium-alloy and polycarbonate construction, together with an operating temperature range from -30°C to 50°C, makes the siren suitable for demanding indoor and outdoor security environments.

Flexible Wall or Ceiling Installation

The supplied mounting plate supports both wall and ceiling installation. The compact 139.9 × 139.9 × 35mm enclosure allows the siren to be positioned where its audible alarm and emergency lighting can provide effective coverage.

UniFi Protect Integration

The USL-Siren integrates with UniFi Protect for centralised security management. It can be managed through the UniFi Protect web interface and UniFi Protect applications for compatible iOS and Android devices.
