1 and 2-level radio repeater with small antenna. Stand-by loss only 0.6 Watt. If required, a FA250 radio antenna can be connected. Installation in suspended ceilings, for example. 100mm long, 50mm wide and 25mm deep. This repeater is only necessary if the structural conditions prevent an undisturbed reception or if the distance between the radio button and the receiver is too large. The antenna FA250 with 250cm cable can be connected instead of the small antenna included in the delivery. Optimally placed, this increases the range considerably. 1-level mode is set ex works. Only the radio signals from sensors are received, tested and transmitted at full transmission power. Radio signals from other repeaters are ignored to reduce the amount of data. The rotary switch can be used to switch to 2-level mode. In addition to the radio signals from sensors, the radio signals of another 1-level repeater are now processed. A radio signal can thus be received and amplified up to a maximum of 2 times. The LED indicates incoming radio signals by flashing briefly. Radio repeater does not need to be trained. They receive and amplify the radio signals from all radio sensors in their reception range.This text is machine translated.
