Eltako FB55EB-pm

Wireless motion sensor for surface mounting, measuring 80x80x27 mm, or for installation in the E-Design55 switch system. Powered by a battery (lifetime of 3 years). The FB55B sends a motion telegram every 2 minutes when movement is detected. If no movement is detected, a non-motion telegram is sent after 4 minutes. If movement is still not detected, a non-motion telegram is sent every 30 minutes. In the factory setting, the upper slide switch is set to P (passive), and light actuators and dimmers automatically turn off if no new movement is detected for 5 minutes. The light can be turned on with the light switch. With the upper slide switch in position A (active), automatic motion-dependent activation is enabled. The lower slide switch allows you to choose the sensitivity: H = high (factory setting) or L = low. The power supply for several years is provided by an internal 3V CR2032 button cell. To change the button cell, simply remove the front plate. The wireless sensor can be integrated with the following actuators and the Professional Smart Home controller.
