Claims
- 1. A method of controlling an electrically activated door control system for operating a door hingedly mounted in a door frame, comprising:
- mounting support apparatus on a mounting surface;
- retaining a handle apparatus in place intermediate said support apparatus and a retaining apparatus, said handle apparatus being for application of a manual input thereto, said handle apparatus being installed adjacent said support apparatus such that said support apparatus is, at least in part, intermediate said handle apparatus and the mounting surface;
- installing a first transducer between said handle apparatus and said support apparatus such that said first transducer is subjected to a compressive force when said handle apparatus is pushed toward said mounting surface, said first transducer providing an electrical characteristic which varies in response to pressure being applied across said first transducer; and
- monitoring said electrical characteristic of said first transducer and providing, in response to said electrical characteristic of said first transducer meeting a first criterion, a first output signal to the electrically activated control system to cause said electrically activated control system to operate the door in a first manner.
- 2. A method of controlling an electrically activated door control system for selectively, alternatively electrically locking and unlocking a door hingedly mounted in a door frame, said method comprising:
- mounting first and second mounting members for supporting a push bar on the door, said push bar having a first end thereof and a second end thereof, said push bar being for application of a manual input to request access or egress through the door;
- retaining said first end of said push bar between said first mounting member and a first retaining member;
- retaining said second end of said push bar between said second mounting member and a second retaining member;
- installing a first transducer between said first end of said push bar and said first mounting member such that said first transducer is subjected to a compressive force when said push bar is pushed toward the door, said first transducer providing an electrical characteristic which varies in response to pressure being applied across said first transducer;
- installing a second transducer between said second end of said push bar and said second mounting member such that said second transducer is subjected to a compressive force when said push bar is pushed toward the door, said second transducer providing an electrical characteristic which varies in response to pressure being applied across said second transducer; and
- monitoring said electrical characteristic of said first and second transducers and providing, in response to said electrical characteristic of either or both of said first and second transducers meeting a first criterion, a first output signal to the electrically activated control system to cause said electrically activated control system to unlock the door.
- 3. A method of controlling an electrically activated door control system to selectively, alternatively electrically activate and deactivate a motor to open a door hingedly mounted in a door frame, said method comprising:
- mounting a mounting member on a mounting surface;
- retaining a plate member in place adjacent said mounting member with a retaining member, said plate member thereby being located intermediate said mounting member and said retaining member, said plate member having a front side thereof and a back side thereof, said back side of said plate member facing said mounting member, said front side of said plate member facing said retaining member;
- operatively connecting a handle to said plate member with at least one spacer member such that said plate member is spaced away from said handle, said handle being for application of a manual input thereto to request that the door be opened, said retaining member being located intermediate said handle and said plate member;
- installing a first transducer means between said back side of said plate member and said mounting member such that said first transducer means is subjected to a compressive force when said handle is pushed toward said mounting surface, said first transducer means providing an electrical characteristic which varies in response to pressure being applied across said first transducer means;
- installing second transducer means between said front side of said plate member and said retaining member such that said second transducer means is subjected to a compressive force when said handle is pulled away from said mounting surface, said second transducer means providing an electrical characteristic which varies in response to pressure being applied across said second transducer means;
- monitoring said electrical characteristic of said first transducer means and providing, in response to said electrical characteristic of said first transducer means meeting a first criterion, a first output signal to the electrically activated control system to cause the electrically activated control system to immediately deactivate the motor for opening the door; and
- monitoring said electrical characteristic of said second transducer means and providing, in response to said electrical characteristic of said second transducer means meeting a second criterion, a second output signal to the electrically activated control system to cause the electrically activated control system to activating the motor for opening the door.
