The OSI Security Devices Wireless Access Management System (WAMS) provides access control and offers real-time remote access controls. Real-time audit, personnel and time schedule changes can be made instantaneously by the system administrator(s) from a host computer. The system administrator(s) has the ability to monitor the system’s performance (signal strength and reader battery levels are graphically displayed), to add, change or delete Users or Credentials, and to review or print Transaction, User, Alarm, or Reader Reports.
(See the article “Going Wireless with OSI’s Wireless Access Management System,” page 58 in the July 2006 issue of Locksmith Ledger.)
WAMS is comprised of any combination of electromechanical mortise or cylindrical reader locks, wall mount system adapters, exit device adapters, and/or Quick Adapters installed at the door openings. The cylindrical reader locks and the Quick Adapters fit standard 161 door preparation without modification. The mortise reader locks install in standard mortise door preparation, requiring only two 3/16” cross bore holes in order to install the reader device onto the motorized mortise lock. Existing earlier-generation OSI devices can be upgraded to incorporate WAMS wireless technology.
The battery powered WAMS electromechanical access control devices are designed for interior or exterior applications. Each WAMS device can be configured to support up to a maximum of 65,000 credential holders. Each credential holder may be programmed to have unique access levels.
The WAMS reader devices communicate wirelessly with the host computer via a device called a Portal Gateway. The DC-powered Portal Gateway provides bi-directional communication between the host computer and the WAMS devices using encrypted data exchange. A single Portal Gateway can be configured to communicate with up to 128 WAMS Reader Devices.
According to OSI Security Devices, the typical range is approximately 150 feet between a Portal gateway and a reader device; it may often be greater. The actual range varies depending upon the building structure, configuration, and RF signals present.
Portal Gateways are wired to the host computer using either a standard Ethernet Local Area Network (LAN) or an 802.11 B/G Wireless network. The maximum distance that a Portal Gateway can be located from the host computer is determined by the network’s capability.
For this installation, the OSI Security Devices Wireless Access Management System was installed into six floors of a large building, where each floor was approximately 20,000 square feet. The height of each floor was approximately 20 feet. The total amount of square footage was approximately 120,000. (See sample floor layout)
Ten reader devices were required to be installed onto doors in each of the six floors. The reader devices would control access into the secure office areas of each floor and areas where access needed to be restricted.
Cylindrical and mortise lock reader devices were primarily used to control access, although several exit devices and one wall-mount system were also installed. Some of the mortise locks had to be replaced as it was not possible or practical to convert them to electro-mechanical (motor-driven) locks. Some of the cylindrical lock chassis were equipped with a Quick Adapter as they were compatible for retrofit to this system. A few earlier-generation OSI OP2000 devices were upgraded to WAMS readers with the WAMS Upgrade Kit. The remaining cylindrical locks were new units. For a list of retrofit-capable cylindrical and mortise locks, consult with the OSI factory.
Although the configuration of each floor varied, there always were two centralized electrical/network closets on each floor. These electrical closets were interconnected between the six floors using existing wiring ducts and CAT-5 network cable. This base configuration provided the foundation for the site survey. The site survey was necessary to:
OSI's WAMS readers are the first battery- powered standalone access control systems capable of real-time remote access control management.
For the third and final article in the OSI Wireless Access Management System (WAMS) series, we will convert an earlier model OMNILOCK electro-mechanical cylindrical leverset to be WAMS-capable. All...
