The RTS26 STATUS is a magnetic contact that signals the opening status of a window and cyclically sends status telegrams wirelessly to an Easywave receiver. If the window is opened in the ON/OFF variant, the LED briefly lights up red and code A (OPEN/ON) is sent. If the window is closed, the LED briefly lights up green and code B (CLOSED/OFF) is sent. For safety reasons, all status changes are resent after 10 seconds. After the last transmission, the current status of the objects is retransmitted at least once every 24 hours and the battery capacity is monitored. If the capacity is low, an undervoltage telegram is sent and repeated at least once every 4 hours.
