    摘要： The invention provides an electronic door lock for a door having a first side and a second side. The electronic door lock includes a locking mechanism, a credential reader, and a programmable control circuit. The locking mechanism is coupled to the door and is movable between a locked position in which the door is inhibited from opening and an unlocked position in which the door is free to open. The credential reader is coupled to the door and is operable to read a credential. The programmable control circuit is coupled to the door and is operable to move the locking mechanism between the locked position and the unlocked position at least partially in response to the read credential. The programmable control circuit is selectively programmed to move the locking mechanism to a pre-selected either one of the locked position and the unlocked position in response to a failure signal.

    摘要： In an RF access control system, a method for establishing a reliable RF signal link between points of the RF access control system. A first RF signal from a first point of the system is transmitted to a second point of the system at a first RF power level that is below a second RF power level used during normal operation of the RF access control system. Once the second point acknowledges the RF signal from the first point, then a pre-determined number of RF packets are transmitted and received back and forth between the first point and the second point at the first RF power level. An RF packet error count is generated in response to the transmitting and receiving of the pre-determined number of RF packets. If this error count is below a certain threshold value, then an indication is provided to an installer of the RF access control system of an RF channel number to be used by the RF access control system during normal operation.
