ABSTRACT:
A remotely controllable door operator system permitting active and passive use of a door includes a transmitter, a receiver, a master timing sequencing mechanism, a clutch-regulated prime mover that can actively move the door, and a mechanism that senses whether the door is fully closed. The door operator is controllable by depressing a single button on the transmitter, which sends a signal to the receiver. If the sense mechanism determines the door is fully closed, the receiver causes the timing mechanism to cause the prime mover to disengage the door latch and to commence actively opening the door for a first time period. The timing mechanism may be user adjusted to control the extent of the door opening by adjusting the length of the first time period.
