2 level wireless repeaters in the housing for single mounting 84x84x30mm. Only 0.8 watt standby loss. We recommend stainless steel countersunk screws 2.9x25mm, DIN 7982 C, for screw fastening on a mounting box with a screw spacing of 60mm. Set of 2 stainless-steel countersunk screws 2.9x25mm and plugs 5x25mm are enclosed. Supply voltage 230V. This repeater is only needed if the building conditions prevent undisturbed reception or the distance between the wireless pushbutton and receiver is too great. The 2-level mode is activated. The signals from sensors and actuators are received, tested and retransmitted with full transmitting power. The wireless signals from another 1-level repeater are also being processed. A signal may therefore be received and amplified twice. Wireless repeaters need not be taught-in. They receive and amplify signals from all wireless sensors within their reception area.
