2-level radio repeater, pure white, glossy, in a housing for surface mounting 84x84x30mm or installation in the E-Design switch system. Standby loss only 0.8 watts. 2 stainless steel countersunk screws 2.9x25mm and dowels 5x25mm are included. Supply voltage 230V. This repeater is only required if the structural conditions prevent uninterrupted reception or the distance between the radio button and receiver is too great. The 2-level mode is activated. The signals from sensors and actuators are received, checked and sent on with full transmission power. The radio signals from another 1-level repeater are also processed. A signal can thus be received and amplified a maximum of 2 times. Radio repeaters do not need to be taught in. They receive and amplify the signals from all radio sensors in their reception area.
