ABSTRACT:
An infrared signal interface enables an infrared detector module to communicate with the door edge signal input of a garage door operator. The infrared signal interface has a power supply for driving the pulsed infrared detector. Pulsed signals are received by a missing pulse detector that controls a relay. The relay may be coupled to the door edge signal of the garage door operator.
