Going Wireless with OSI's Wireless Access Management System

OSI's WAMS readers are the first battery- powered standalone access control systems capable of real-time remote access control management.


The development of electromechanical locks has taken a major leap forward with the introduction of the OSI Security Devices WAMS, an acronym for Wireless Access Management System. WAMS readers offer real-time communication with the host computer without the wiring or controllers that are normally required for communication and operation of hard-wired systems. No longer must a wireless battery-powered access control device require a person to either go to the device in order to download the audit trail or walk to the device in order to program personnel or time-schedule changes.

The OSI Wireless Access Management System is comprised of electromechanical reader locks, wall-mount systems (using separate electrified locking mechanisms), exit device adapters, and Quick Adapters that are installed at the door openings. To wirelessly communicate with the host computer, OSI has developed the Portal Gateway. The Portal Gateway, which is very similar to a wireless router, can communicate with the WAMS locking device(s) wirelessly using an encrypted data exchange.

Portal Gateways are DC powered and are wired to the host computer using either a standard Ethernet Local Area Network (LAN) or a Wireless 802.11 B/G Wireless network. The maximum distance a Portal Gateway can be located from the host computer is determined by the network. For example, on a typical university campus network, Portals may be located anywhere on the campus; and, if connectivity is available to satellite campuses in other cities, states, or around the globe, then those campuses may also connect Portal Gateways to this Wide Area Network (WAN).

The WAMS reader locks are available in both cylindrical and mortise configuration. The cylindrical reader locks fit standard 161 door preparation, minimizing retrofit installation time. The mortise reader locks install in a standard mortise door preparation and require an additional two 3/16-inch holes to install the reader lock on a door. Quick Adapters have been developed for retrofitting to existing specific Schlage Grade-1 cylindrical lock models to become WAMS compatible. All OSI WAMS readers are ADA compliant.

These battery powered electromechanical access control devices are self-contained and are designed for exterior or interior applications. Outdoor weather resistant versions withstand temperature variations from minus 40 degrees C to 54 degrees C. Reader locks are available with options including Request to Exit (REX), Door Switch Monitoring (DSM) and/or Door Lock Monitoring (DLM).

Each WAMS device can support up to 2,000, 10,000, 20,000, 32,000, or a maximum of 65,000 credential holders at one time. Each cardholder can be programmed for unique access levels. Expanding the user capacity of a reader lock only requires upgrading the firmware using a software-entered key.

WAMS devices are capable of supporting up to 176 user-defined Time Zones with six time intervals per Time Zone, where each Time Zone can cross midnight. There are 32 user-defined holiday periods. A unique feature of the holiday periods is that they can be set by the day or date. For example, News Years Eve is always Dec. 31; however, Thanksgiving is always the fourth Thursday of November. By having both methods of defining a holiday, WAMS can eliminate having to reprogram certain holidays every year.

The WAMS devices control access using single or dual credentials. For example, a user may be required to present only his Proximity card; or he may be required to present his Proximity card plus enter a keypad PIN. The WAMS devices are capable of handling multiple reader technologies including keypad entries, and can accommodate several different card formats.

The available card formats include magnetic stripe tracks 2 or 3, HID proximity cards, MIFARE cards, CAC contact smart cards, and FIPS contact-less smart cards. Keypad users may enter user ID codes ranging from four to 10 digits in length and keypad PINs from three to six digits. Applicable card formats are determined by the selected configuration of the WAMS device. Each WAMS device has the storage capability of its audit trail (see Table 1 below).
