frient Smart Siren (SIRZB-111) is a Zigbee 3.0 mains-powered indoor siren with Zigbee router functionality.
The device can be used to play alarm and status notification sounds. The built-in siren produces a sound pressure level of 90 dB at a distance of one metre. Eight different alarm sound types and four volume levels can be configured, making it suitable for intrusion, fire, emergency, and other security automations.
The Smart Siren operates directly from a 230 V wall socket. Thanks to its mains power supply, it also functions as a Zigbee router, forwarding data traffic from other Zigbee devices and helping to extend the coverage of the Zigbee mesh network.
As a mains-powered Zigbee router, the device forwards the data traffic of other Zigbee devices and expands mesh network coverage. In Home Assistant, Zigbee2MQTT, ZHA, SmartThings, Homey, and other compatible Zigbee systems, it can be linked with security sensors, door and window sensors, motion detectors, smoke alarms, and water leak detectors.

Its product range includes door and window sensors, motion sensors, temperature and humidity sensors, air quality sensors, water leak detectors, vibration sensors, smoke and heat alarms, smart plugs, energy meters, and other smart home accessories.
frient products use standard Zigbee 3.0 communication and are therefore compatible with a wide range of Zigbee gateways. They are supported by Home Assistant, Zigbee2MQTT, ZHA, SmartThings, Homey, and many other Zigbee-based systems. Available features may vary depending on the gateway and its device support.
Key Product Features
- 90 dB audible alarm: The built-in siren can produce a 90 dB alarm at a distance of one metre.
- Eight alarm sound types: Different warning tones can be selected for various security and emergency events.
- Four volume levels: The alarm volume can be adjusted to the installation location and the purpose of the automation.
- Zigbee router: The device forwards the data traffic of other Zigbee devices and extends mesh network coverage.
Smart Home Protocols and Platform Compatibility
- Zigbee 3.0: Uses wireless communication and mesh network routing. A compatible Zigbee gateway or coordinator is required.
- Home Assistant: The EU and UK versions of the Smart Siren are supported under the Works with Home Assistant programme. The device can be used locally with a compatible Zigbee adapter.
- Zigbee2MQTT: Supported as model SIRZB-111. Siren control, warning profiles, and alarm states are available.
- MQTT integration: When Zigbee2MQTT is used, alarm commands and status data can be handled through MQTT messages.
- ZHA: Can be connected through the Home Assistant Zigbee Home Automation integration. Available sounds and alarm parameters depend on current device support in the integration.
- Samsung SmartThings: Can be used in security automations with a compatible SmartThings Zigbee hub.
- Homey: Can be linked to alarm flows, sensor events, and security automations through the frient integration.
- Local operation: When used with Home Assistant, Zigbee2MQTT, or ZHA and a local Zigbee coordinator, the siren can be controlled without an internet connection.
Smart Features
- Siren on and off control: The audible alarm can be started and stopped manually or through automations in a compatible smart home system.
- Timed alarm: In Zigbee2MQTT, the alarm can be configured to stop automatically after a specified period.
- Alarm sound types: Intrusion, fire, emergency, panic, and other Zigbee IAS warning tones can be selected.
- Volume adjustment: Low, medium, high, and very high volume levels can be configured.
- Visual indication: In supported Zigbee2MQTT configurations, the flashing light indication and its intensity can also be adjusted.
- Alarm duration: The warning duration can be specified in seconds.
- Intrusion alarm automation: The siren can be triggered by door and window, motion, or vibration sensor events.
- Fire and water damage alarm: Smoke, heat, or water leak sensor events can trigger a dedicated alarm sound.
- OTA firmware update: Wireless firmware updates are supported through Zigbee2MQTT.
