Abstract

A very HF radar is connected by a switch (9) controlled by relay (10) to a supply which controls the door opening (19) and the door closing motors (19). The motor circuits are controlled by single pole inverters (16), (17) connected to the operating relay (15). The radar detects movement and passes a current to the transistor (13) which activates relay (15). This causes the door to open and be held open as long as the movement continues. After a delay of 3 to 5 seconds the inverters connect the closing motor in circuit and the door closes. As soon as the closing signal is given at the end of the delay the opening signals are neutralised.
