Ubiquiti UniFi UP-SIREN Alarm Sensor

Ubiquiti UniFi UP-SIREN – 110dB Alarm and Emergency Light

The Ubiquiti UniFi UP-SIREN is a PoE-powered alarm siren and strobe light designed for smart home and building automation environments. It integrates directly into the Ubiquiti ecosystem for centralized monitoring and instant alert notification.

• 110dB alarm siren delivers audible warning across large areas
• Integrated emergency strobe light provides visual alert for hearing-impaired users or high-noise environments
• PoE-powered — no separate power supply required, simplifying installation
• Wired LAN communication ensures reliable, low-latency alert triggering

What sets the UP-SIREN apart

Unlike standalone alarms, the UP-SIREN combines audible and visual alerting in a single PoE-powered unit, reducing installation complexity and eliminating the need for battery maintenance. Its white finish blends discreetly into ceilings and walls.

Ideal for...

Smart home installations, small offices, and commercial spaces where immediate, multi-sensory alerting is needed. Particularly suited for environments where a silent alarm would go unnoticed.

Application of the UP-SIREN

Mount the unit on a ceiling or wall within the Ubiquiti UniFi network coverage area. Connect via standard Ethernet cable to a PoE switch or injector. Configure alarm triggers through the UniFi controller to link the siren with motion sensors, door contacts, or manual alert events.
