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 OSI electro-mechanical systems manufactured after year 2000 can be upgraded to the latest electronic capabilities. This is advantageous for both you and your installed customer base. Your customers save money by not having to purchase new replacement hardware. You are appreciated by your customers for saving them money.
The OSI Wireless Access Management System provides instantaneous, real-time communications for controlling access. OSI WAMS is comprised of three basic components:
1) The readers, mounted onto the door, which control access
2) The host Windows™ based computer that is programmed to determine who, when, and where to have access
3) The Portal Gateway, which is connected to the computer, operates very similar to a wireless router and communicates wirelessly with the readers.
The WAMS system allows remote monitoring and programming of the access control system, thereby eliminating the need for direct “face-to-face” communication with each reader lock. Even the reader's battery life can be determined at the host computer.
For this article, we chose the OMNILOCK OP2000, a single-door electronic access control system based on an ANSI Grade 1 cylindrical leverset. The OP2000 is equipped with an 11-button keypad, proximity reader and keyed cylinder. The OP2000 leversets are Fail Secure and locked electronically from the outside. The inside lever is always unlocked, providing unrestricted egress.
To make the upgrade path relatively easy, OSI Security Devices re-designed their electronic housing in 1999 and then continued to use that basic housing assembly for most* of their key-in-knob/leversets, exit trim, mortise locks, and wall-mounted systems.
* NOTE: The OMNILOCK OM250 and the traditional OMNILOCK OM100-300-500 Series systems are manufactured with their original cold-rolled steels housings. These systems cannot be upgraded to WAMS capability.
CONVERTING TO OPW2000
Step 1. Remove the reader from the door.
Step 2. Carefully remove the five Phillips head screws securing the battery cover and the back plate from the exterior housing assembly. The gasket should hold them together. There is no need to remove the gasket.
Step 3. Remove the four AA batteries.
Two wire connectors may be attached to the battery side of the circuit board. One is for the motor connection. The motor wires are red and black. If the lock is equipped with key bypass detection, a second connector will be present. The two key bypass detection wires are yellow.
Step 4. Carefully slide the connector(s) off of the circuit board.
Step 5. Remove the two Phillips Head screws securing the main circuit board to the exterior housing.
Step 6. Unscrew the mounting stand from between the two battery bases.
Step 7. Carefully lift the circuit board from the top until you can see the two connectors. The main circuit board is connected to a second circuit board by a ribbon cable and a four-wire harness.
Step 8. Carefully pull the four-wire connector off the main circuit board. Do not attempt to remove it from the secondary circuit board.
Step 9. Carefully pull up on the two outside clips of the ribbon cable connector. Once these clips have been lifted out of the locked position, the cable will slide out of the connector.
Step 10. Lift the main circuit board out the housing. Place this circuit board into an anti-static bag (provided with upgrade kit) for storage and protection.
Note: Several labels are inside the exterior housing. One label contains the serial number of the lock. This number can be used to identify the model of the lock by calling OSI Security Devices. Once identified, OSI can provide sales history, servicing, and programming information.
The OSI WAMSwas installed into six floors of a large building, where each floor was approximately 20,000 square feet.
SARGENT introduced the standalone Profile Electronic Access Control Series Locks in 2001. These electro-mechanical locks can control access electronically using keypad, Radio Frequency (RF) technology...
OSI's WAMS readers are the first battery- powered standalone access control systems capable of real-time remote access control management.
SARGENT wireless technology provides access control features during both online and offline operation. Up to 2,000 users can be programmed per lock, with a 10,000-event audit trail.
