Bosch Smoke Detector II Zigbee

Alarm in case of fire

The interlinked smoke alarm reliably alerts you straight away if smoke develops using the sirens on site. If there’s a fire, it forwards the signal to all integrated smoke alarms and Twinguards. The smoke detector also informs you when you’re out via push notification on your smartphone. All you need to do to call the fire brigade is tap the emergency call button on the app screen.
