Sicherheits-Funk-Schaltungsanordnung für ein Abluftsystem

摘要

control element on window, door or air inlet flap connects electrically to single- or multi-channel transmitter (S) to send first signal (0) as control element shuts. If battery is low power, the first signal still transmits but is suppressed as second signal (1). Receiver (E) fitted elsewhere assesses first or second signal and uses relay or triac (K) to disconnect current path to power outlet (D) supplying ventilating system.
