Abstract

See full text

A window or door position detector includes an RFID tag attachable to the window or door, and a transceiver. The transceiver emits an activating signal to the tag. The tag in turn responds with an identifying RF signal indicative of a predetermined position of the window or door. The detector includes a transceiver which can communicate with both the tag and a displaced monitoring system control panel.
