Wireless PIR presence detector with daylight harvesting – up to 10 years of battery life, ideal for retrofits.
The BCS107 is a battery-powered, wireless Bluetooth ceiling sensor for the Keilton+autani wireless network. It combines PIR presence detection with daylight harvesting and is configured entirely via the Keilton+autani app.
As it needs neither mains power nor control wiring, the BCS107 is perfect for retrofits in existing buildings: mount the sensor, add it via the app, done. The supplied CR123A battery lasts up to ten years.
