The wireless Easyclick wall motion detector gets its energy from solar cells and detects movement using a passive infrared sensor. The motion detector is easy to install and saves energy. For example, lighting switches ON automatically when a person enters a room and OFF automatically after a delay time when they leave. The motion detector sends radio signals to the configurable Easyclickpro receivers or all EnOcean interfaces for building system technology. At a brightness of < 50 lux, battery operation (CR2032) is possible. Technical data: Transmission frequency: EnOcean 868.3 MHz Detection range: approx. 12 m Installation height: 2-3 m Transmission range: approx. 25 m Minimum brightness: 50 lux for automatic ON/OFF Energy generator: Solar cell, internal gold cap Charging start-up time: Learning = approx. 4 min. at 100 lux approx. 1.5 min. at 200 lux Sending movement = approx. 6 min. at 100 lux approx. 3.5 min. at 200 lux for test mode = approx. 5.5 hrs. at 200 lux Full charging time: 9 hrs. at 200 lux Charging times for operation: 3 hrs. a day at 200 lux Operating time in the dark: approx. 48 hrs. Battery operation: approx. 1 year depending on of frequencyTransmission interval: immediately when motion is detected . variable every 60 sec. at 300 lux to 300 sec. at 50 lux . OFF every 10 and 30 min. after the last movementEnOcean Equipment Profile: EEP A5-07-01 Housing: PC, pearl white, similar to RAL 1013 Protection class: IP 50 Dimensions: 160 mm x 60 mm x 37 mm Weight: 125 g Ambient conditions: Installation only in buildings, -10 ° to 40 °C, 20 % to 95 % relative humidity non-condensingSuitable receivers: all Easyclickpro receivers.
