Bosch Smart Home - Zigbee Smoke Detector II BSD-2

Bosch Smart Home Zigbee Smoke Detector (BSD-2)

The Bosch Smart Home BSD-2 smoke detector is more than a standard fire alarm — it's an integrated multi-functional safety device for your home.

It not only meets legal smoke detection requirements but also enhances safety with Zigbee 3.0 connectivity, remote alerts, and smart home integration via the Bosch Smart Home Controller.

Main Features

• Dual alert system: Alarms locally with an 85 dB siren and remotely via app notifications (including room location).
• Integrated smart protection: Activates escape lighting, raises roller shutters, and streams live video from your cameras in case of fire.
• Break-in deterrent: Also functions as a siren in the event of unauthorized entry (integrated with door/window sensors or motion detectors).
• False alarm prevention: Dirt compensation continuously adjusts the threshold to reduce false alarms from dust or pollution.
• Battery life: Up to 5 years with a 3 V lithium CR17450 battery (included and replaceable).
• Apple HomeKit® compatible: Extend functionality with HomeKit-compatible devices across ecosystems.

System Integration

Only compatible with the Bosch Smart Home system and requires a Bosch Smart Home Controller for full functionality.
