Ubiquiti Smoke and CO Alarm
The Ubiquiti Smoke and CO Alarm (USL-Smoke) combines smoke and carbon monoxide detection with UniFi SuperLink wireless connectivity. Integrated smoke and CO sensors continuously monitor the installation area for potential hazards, while an 85 dB alarm at 3 m provides a clear audible warning. SuperLink connectivity enables integration with UniFi Protect for centralized monitoring and management.
The EU version operates within the 865.1–869.5 MHz SuperLink frequency range and supports a maximum wireless range of up to 2 km. A replaceable CR123A lithium battery powers SuperLink connectivity, while two non-replaceable L91 lithium batteries supply the smoke and CO alarm functions. Ubiquiti specifies up to 10 years of battery life for SuperLink connectivity and a 10-year service life for the smoke and CO alarm batteries.
The polycarbonate enclosure measures Ø 120 × 48.5 mm and weighs 311 g. Controls include a test/silence button, function button, factory reset, tamper switch and deactivation switch. The specified operating temperature range is 0 to 40 °C. Compliance with standards including EN 14604 and EN 50291-1 makes the USL-Smoke a connected residential safety solution combining local smoke and CO alarm functionality with centralized UniFi Protect monitoring.

The Ubiquiti Smoke and CO Alarm USL-Smoke provides combined smoke and carbon monoxide detection for residential environments. When a hazard is detected, the unit generates an 85 dB audible alarm and can communicate via UniFi SuperLink as part of a UniFi Protect deployment, enabling centralized status monitoring. SuperLink provides a specified wireless range of up to 2 km under suitable conditions. The alarm supports both wall and ceiling mounting and is suitable for residential rooms, hallways and other locations requiring smoke and CO detection. A compatible SuperLink Gateway is required for connected operation. Ubiquiti explicitly specifies the USL-Smoke for residential use only.
