Access control using serial discretely coded RF transmissions initiated by a single event
First Claim
1. A controller for operation of RF transmitting means having first and second transmission channels communicating at an entryway with RF controlled actuating means remotely receiving different ones of RF access control transmissions from the first and second transmission channels and, responsive thereto, initiating required first and second serial accesss control functions, said controller comprising:
- user actuatable input means for selectively generating a single electrical initiation signal;
first and second signal conditioning means connected to receive said single electrical initiation signal and, responsive thereto, for providing first and second conditioned output signals;
first and second means for coupling said first and second conditioned output signals with the RF transmission means for enabling the first and second transmitting channels, respectively; and
signal delay means at said second signal conditioning means for delaying output of said second conditioned output signal relative to output of said first conditioned output signal.

Abstract
Apparatus and methods for entryway access control using serial discretely coded radio frequency transmissions initiated by a single user access request signal. The control apparatus is battery operated and includes a user actuatable input selectively generating a single electrical initiation signal. Circuitry provides first and second conditioned output signals responsive to receipt of the single electrical initiation signal, the output signals enabling first and second transmission channels, respectively, of an RF transmitter or transmitters. A signal delaying circuit delays output of the second conditioned output signal relative to output of the first conditioned output signal.

8. An entryway access control for communicating at an entryway with first and second RF controlled actuators remotely receiving different ones of coded RF access control transmissions and, responsive thereto, initiating required first and second serial accesss control functions, said control comprising:
-
user actuatable input means for selectively generating a single electrical initiation signal; first and second signal conditioning means connected for providing discrete first and second conditioned output signals responsive to generation of said single electrical initiation signal; coding and transmission means having first and second RF transmission channels connected for receiving said first and second conditioned output signals and, responsive thereto, enabling said first and second transmission channels, respectively, for generation of differently coded RF transmissions; signal delay means at said second signal conditioning means for delaying output of said second conditioned output signal relative to output of said first conditioned output signal; and means adapted for coupling said control with a battery to provide all operational power for said control. - View Dependent Claims (9, 10, 11, 12, 13)

14. A method for controlling access at an entryway having at least first and second RF controlled actuators for remotely receiving different RF access control transmissions and, responsive thereto, initiating required first and second serial access control functions, said method comprising the steps of:
-
user initiation of a single entryway access request signal; providing a first conditioned electrical output signal responsive to initiation of said single request signal; utilizing said first conditioned electrical output signal to generate a first RF access control transmission to which the first RF controlled actuator, but not the second RF controlled actuator, is responsive; providing, after an established time delay relative to provision of said first conditioned electrical output signal, a discrete second conditioned electrical output signal responsive to initiation of said single request signal; and utilizing said second conditioned electrical output signal to generate a second RF access control transmission to which the second RF controlled actuator, but not the first RF controlled actuator, is responsive. - View Dependent Claims (15, 16, 17, 18, 19, 20)
