Appl. No.:

10/022867

Inventors:

Andrew M. Pickard - Carrollton TX, US

International Classification:

H01H 35/00

US Classification:

307117, 34082531, 34082572, 307116, 307139

Abstract:

A wireless remote control lock system for residential and commercial building pedestrian doors includes an electrically powered striker plate assembly having a striker plate member moveable between positions for engagement and disengagement with a door latch member. The striker assembly is adapted to be connected to a control unit which supplies low voltage DC power to the striker assembly and includes a radio frequency range signal receiver and a circuit responsive to receiving signals from an operator controlled radio transmitter to effect indefinite or momentary operation of the striker assembly to unlock a door. The control unit circuit includes a first self-latching relay, a selector switch and a second relay for selecting an operating mode of the system wherein the door may be unlatched momentarily (for about 3. 5 seconds, for example) or indefinitely until a second signal is transmitted by the transmitter to the receiver.
