摘要:
An integrated lock body system for securing access points. An electronic door lock has a lock body, at least one electrical component within the lock to be monitored, and at least one output for connection to an external unit located remotely from the electronic door lock for monitoring load resistance between the external unit and the electronic door lock. A circuit is mounted adjacent to or within the electronic lock body. The circuit includes an electrical connection to the at least one electrical component within the electronic door lock and an external electrical output for connection to the external unit. The circuit further includes at least one resistor between the electrical connection to the at least one electrical component within the electronic door lock and the external electrical output, the at least one resistor imparting a desired load resistance capable of being monitored by the external unit.

A method of operating a lock from a portable remote device includes sending a radio frequency identification signal from the portable remote device to a controller for the lock, and receiving the radio frequency identification signal at the lock controller and identifying the remote device as an authorized user of the lock. The method then includes sending a sound frequency identification signal from the portable remote device to the lock controller, receiving the sound frequency identification signal at the lock controller and identifying the remote device as an authorized user of the lock. The method further includes authorizing operation of the lock in accordance with the radio or sound frequency identification signal from the portable remote device. A system for practicing the method includes a lock controller capable of receiving a radio frequency identification signal and a sound frequency identification signal from the portable remote device.

An exit device includes a rail having opposite first and second ends and a rear portion with a first opening adjacent the first rail end for attachment to the door surface, the first rail end further having a front portion that inhibits access to the first rail opening in a direction normal to the rail rear portion. The method for installing it includes securing a mount having a cantilevered portion extending therefrom to the door at the surface first end such that the mount cantilevered portion provides a space between the cantilevered portion and the door and placing the rail against the door surface such that the mount extends through the first rail opening, sliding the rail to engage the rail rear portion adjacent the first rail opening between the mount cantilevered portion and the door and securing the second rail end to the door surface.

A door having acoustical sound isolation properties includes a rail or stile having surfaces with a first, second and third planar portions stepped inward from and parallel to each other. Blocking layers are disposed parallel to and below one of the door surfaces, with each blocking layer having an edge with an extending flange contacting and extending along the second planar portion of the third surface of the stile or rail. The flanges of the blocking layers restrict movement of the layers toward each other. Soft acoustical material is disposed in the door interior. Flexible transition layers extend along the stile or rail third planar portions and extend over the blocking layers and the soft acoustical material to provide support against denting forces to the door.

An integrated access control system for wirelessly managing an access point comprises a wirelessly operable electronic door lock coupled to the access point, a computing device controlled and operated by a first user, and a multi-radio host device located at or adjacent to the access point, the host device being in communication with the electronic door lock and the computing device. Each of the computing device and the host device comprises a memory configured to store instructions to enable the device to wirelessly communicate with the electronic door lock and the other device, a processor configured to execute the instructions, a low power wireless communication radio, and a high power wireless communication radio, wherein the host device and computing device are selectively capable of bidirectional communication via each of a low power radio communication channel and a high power radio communication channel. The host device further comprises at least one mechanism for detecting and/or capturing the presence of a second user accessing the access point, and the computing device further comprises a display and a user interface. The host device is configured to send event and/or system notifications to the computing device and receive operational and/or configuration commands from the computing device via the low power radio communication channel, and the host device is further configured to selectively operate the host device high power wireless communication radio to transmit an image and/or video captured by the host device at least one mechanism to the computing device in response to a command from the computing device via the low power radio communication channel.

摘要:
A method for managing light energy received from at least one light source by at least one light sensor in an access control system. The method comprises receiving light energy by the at least one light sensor, measuring the amount of light energy received by an energy harvesting manager interconnected with an access control device, and determining whether the measured amount of light energy is above a predetermined threshold. If the measured amount of light energy is above the predetermined threshold, the method comprises converting the light energy into harvested energy by at least one energy harvester. If the measured amount of light energy is not above the predetermined threshold, the method comprises adjusting the amount of light energy available to the at least one light sensor from the at least one light source until the predetermined threshold is reached.
