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.

Time Zones: This menu offers end users the opportunity to change Access Levels automatically on some or all of their WAMS readers. The available access levels are Unlock, Unlock with ID, ID Required, ID plus PIN Required, Facility Card Mode, Lockout, and Toggle Entry. These events may be set up to automatically occur at desired times throughout the day, week, month, and year. For example, a typical Time Schedule will for a Personnel Office would be: 0730 Unlock with ID, 1700 ID Required, 2100 ID plus PIN required. In this time schedule, any authorized code or card user who presented their credential to the door after 0730 would unlock the reader and the reader would remain unlocked until 1700 hours. At 1700 hours the reader would automatically re-lock and go to the ID Required state. In the ID Required access level, readers unlock momentarily for the default unlock time (usually three seconds, but this setting may be set for each individual so in the case of a handicapped person, a door can be unlocked for 15 seconds). At 2100, this reader will require both an ID card or code PLUS an keypad PIN to allow entry. In addition to automatic time-scheduled events, users may set up holidays for any or all of their readers.

Users: The Users menu allows the system administrator to add or delete users from the system, add or delete users to or from particular readers, or to associate users with User Groups or Time Zones. In the WAMS system, each user may have as many as four credentials associated with his user profile. For example, a particular end user may be able to use his or her Proximity Card or ID Code on some or all of the readers in a facility.

The WAMS Software allows multiple system users to log on to the database simultaneously. Users may also be granted certain privileges or may have restrictions assigned to their system password. By clicking on File and then on Manage Application Users, the system administrator may grant or restrict access privileges to each individual system password user.


The WAMS Transactions software application allows system administrators to monitor, view, and sort reader transactions. The following transactions are currently displayed in the Transactions Log:

Entry: This event indicates the name, time and location of the reader accessed by an individual.

Attempt: This event indicates when an end user makes an attempt to open a particular reader. If an unknown user attempts to enter using a card or code, the system will log an attempt and it will capture the user's attempted card or code number in the transaction log.

Key Bypass: On reader locks that have this option, a Key Bypass is recorded in the transaction log. When a key is used to enter the door, the Alarm Shunt is triggered.

Access Level Change: Any time-scheduled or manager-induced access level change is reported.

Request to Exit: On WAMS reader locks with this option, a Request to Exit is recorded any time the inside lever is rotated and the Door Switch Monitoring (DSM) contacts detect that the door is actually opened.

Forced Entry: This alarm state is immediately reported back to the host computer when a door is forced open. Reader locks that have this option are equipped with a Door Switch Monitor (DSM) contact and an REX switch.

Door Open Too Long: This event is recorded in the transaction report if a door is held open longer than the reader's Alarm Shunt set time.

Lost Data: If a Portal Gateway or a device goes off-line for any reason, a Lost Data event is reported in the transaction log.

Low Battery: A Low Battery event is recorded in the transaction log whenever a reader's batteries get to a level of 4000 milli-volts. At this level, the reader should still operate properly for 10,000 more cycles.

WAMS Transactions software has the ability to report alarms and sound an audible alarm on the host computer to notify system users that an alarm has been triggered. It utilizes the latest .NET Framework software that allows end users to sort their transactions however they wish.

WAMS Statistics Monitor software application provides real-time monitoring of the WAMS system's operation. This software application monitors four system statistics:

Voltage: This field monitors the battery voltage of the WAMS Readers.

Signal: This screen monitors and displays the radio signal strength at the reader and at the Portal Gateway. Measurements are in decibels (dB).

Packet Ratio: This field monitors and displays the quality of the data packets that are transmitted to and received from the WAMS Readers and Portals. The Packet Ratio at the Portal and at the Reader are both monitored and displayed.

User Capacity: This field displays not only the particular readers user capacity (2000, 10000, 20000, 32000, or 65000 users each), but also displays how many users are actually enrolled in a particular reader.

The Statistics Monitor is not only a troubleshooting and housekeeping tool, but it provides a powerful function as an aid to setting up or expanding a WAMS System. End Users may move their readers from place to place and verify that signal strength remains high and that data packets are of high quality.
