The frient Smart Siren UK (Zigbee) is a sophisticated indoor security solution designed to provide both audible deterrence and enhanced network reliability for your smart home. Operating on the Zigbee 3.0 protocol, this versatile device acts as a powerful deterrent against intruders while simultaneously serving as a signal repeater to eliminate dead zones in your mesh network.

Advanced Audible Deterrence
Engineered to be outspoken, the frient Smart Siren emits a high-frequency 3.2 kHz alarm at a volume of 90 dB (measured at 1 metre). This powerful sound is designed to alert occupants and discourage unauthorised visitors immediately. Users can customise their experience with multiple alarm sounds and volume levels to suit different triggers within their security ecosystem.
Uninterrupted Protection with Battery Backup
Security should never depend on a stable power grid. The frient Smart Siren features a built-in battery backup, ensuring the device remains fully operational during power outages. It also includes power-outage detection, sending immediate alerts to your smart home hub if it is disconnected from a primary power source, providing continuous peace of mind.
Zigbee Range Extension
Beyond its security functions, this device operates as a Zigbee router. By plugging the siren into a standard UK wall outlet, you effectively extend the range of your smart home network. This helps strengthen the wireless communication between your hub and other Zigbee sensors that may be positioned behind thick walls or at the far reaches of your property.
