An improved door edge safety sensor for use with an automatic door operator which uses a motor to move a door between open and closed conditions with a controller for controlling operation of the motor and, an improved sensor comprising a tactile obstruction detector for generating a safety signal, a door vibration detector for detecting movement of the door, a safety signal transmitter operable in response to detected door motion, and control electronics which monitor the obstruction detector and the vibration detector and direct the signal transmitter to reverse the motor upon the door engaging an obstruction which reverses the door to an upward direction.

Monitored radio frequency door edge sensor

A radio remote-controlled door operator for use, among other uses, as a residential garage door operator. The transmitter contains two buttons, one to produce normal door operation and the other to set the operator into a 'secure' mode wherein it will be non-responsive to further valid operating codes until reset. In addition, a second deeper level of security may be established by means of a vacation switch which disconnects the operator from the AC power supply. The operator system comprises a microprocessor which is programmed to perform various accessory functions even through the accessories may not be present. Various microprocessor inputs are tied to a false 'safe' level so that even though the accessory programs are run, no outputs result and no interference with normal door operation is produced.
