The Ubiquiti USL-Smoke is a battery-powered smoke and carbon monoxide detector that communicates with the UniFi Protect system via SuperLink wireless connection. It serves as a sensor for detecting smoke and carbon monoxide in indoor environments and is part of a comprehensive building security system. The wireless connection enables seamless integration into existing UniFi networks, allowing central monitoring and alerting through the UniFi Protect platform.

Applications
This detector is intended for use in residential and commercial spaces where early detection of smoke and carbon monoxide is required. It is particularly suitable for rooms where continuous electrical power is not available or where installing fixed wiring is not economically or technically feasible. The SuperLink technology enables stable communication over short to medium distances within a building, with the wireless connection routed through the UniFi network.

Functions and Features in Detail
The USL-Smoke detects smoke and carbon monoxide and sends an alarm signal via the SuperLink wireless connection to the UniFi Protect system upon detection. The battery power supply ensures autonomous operation without external power. The battery life lasts up to 10 years, ensuring long-term operational reliability with minimal maintenance. The wireless connection enables bidirectional communication, allowing the sensor’s status (e.g., battery level, alarm) to be monitored within the system.

Technology Explained Simply
The SuperLink wireless connection is based on a proprietary wireless protocol developed by Ubiquiti, optimized for reliable and secure communication within the UniFi ecosystem. The device transmits data over the existing network, eliminating the need for additional cables or routers. Smoke detection is achieved using optical sensors, while carbon monoxide is detected via chemical sensors. Combining both functions in a single device enables comprehensive hazard detection in one sensor.

Compatibility and Accessories
The USL-Smoke is specifically designed for integration into the UniFi Protect system. It requires a compatible UniFi Protect station or camera to serve as a gateway for the SuperLink wireless connection. Communication occurs over the existing network, so no additional wireless modules or routers are needed.

Installation and Mounting
Installation is performed at an appropriate location within the room, such as on the ceiling or wall, according to the manufacturer’s instructions. Mounting does not require any electrical connection, as the device is battery-powered. The wireless connection is automatically established with the UniFi Protect system once the device is powered on and registered in the network. Manual configuration is possible via the UniFi Protect software.

Operational Advantages
The USL-Smoke offers long-term operational reliability with a battery life of up to 10 years, minimizing maintenance intervals. The wireless connection enables flexible installation without cabling. Integration into the UniFi Protect system allows central monitoring and alerting, reducing response time in emergency situations. Combining smoke and carbon monoxide detection in a single device reduces the number of required sensors and simplifies system architecture.
