Obsolete Product Resources
Within this page you will find information on various products we no longer manufacture in hopes to help troubleshoot older installations. Replacement parts for some older control systems may still be available. Most units can also be fitted with a new 6500 Series Control Head as well.

The 6789 PLC (Keyence Programmable Logic Controller)
In an effort to expand our functionality and obtain certifications on our control head, we decided to phase out the 789 printed circuit board in favor of the Keyence Visual KV series programmable logic controllers.
The majority of our models used the Keyence KV-16DR (internal part number 6789). Some models had a larger version with expansion modules as well.
Due to Keyence’s discontinuation of the Visual KV series in late 2017, we opted to switch to a different brand rather than use the replacement model they proposed. This was mainly because of physical size constraints and lack of a user interface for changing settings and getting readouts. We have since generated replacement logic for almost every model available during the life of the controller.
As the Keyence model has reached End of Life status, we are no longer able to obtain or provide replacement PLCs and expansions. We are glad to re-flash the logic on any KV16-DR PLCs sent in to us at no charge (including refurbished units or units purchased elsewhere), so long as they are otherwise functional. Simply contact us and let us know what you need and we will take care of it!
Upgrading to our latest Gen. 3 equipment allows for the same functionality but with better temperature range along with a text based HMI for configuration while serving as a direct replacement for either the Keyence PLC or our 789 board (in almost all cases).

The 789 Control Board (Printed Circuit Board)
The 789 Control Board was used on many different models throughout the years. This board featured a removable chip that allowed it to be used on a variety of different turnstiles.
Almost all of our turnstiles used the CA-1 chip, which contained our standard controller logic. Optical turnstiles were once manufactured with a 789 board and a CA-4 chip. The RD-70 was a 789 board with a CA-7 chip. Motorized gates were a slightly modified 789 board with a CA-10 chip.
Due to the sheer number of 789 boards in the field, we still carry and offer them as replacement parts. However, this board was phased out of production in late 2012 in favor of the Keyence Visual KV series logic controller system. This change allowed us to obtain an ETL Recognized Component, certified by Intertek to conform the the following standards: UL 294, UL 325, UL Subject 2593, CAN/ULC S319, CSA C22.2#247.
While the 789 board as a whole functions quite similar to our newer systems, its inputs were NPN (sinking) while our logic controllers have PNP (sourcing) inputs instead. As such, some existing add-ons in the field, such as proximity sensors, may be incompatible with a new controller without additional replacement components.

The 6100 Series Control Head
The 6100 Series Control Head was used for the majority of our product line up until the 6500 Series Control Head was released.
The 6100 Series Control Head’s mounting bolt pattern matches the 6500, so swapping out for a new head is a breeze.
Many of the components used on the 6100 are used in the 6500 design today. These include the solenoids, springs, and hydraulic shock.
While we still try to support the 6100, part availability is limited. Please contact us with any part requirements and we will see if we are able to assist.
The 8100 Series Control Head
A big brother to the 6100, the 8100 Series Control Head was used on some of our larger full height turnstiles to accommodate the extra weight. The casting, cam shaft diameter, cams, solenoids, locking pawls and hydraulic shock are approximately 50% larger than a 6100.
Instead of manufacturing a larger version of a 6500 Series Control Head, we opted to replace some components with larger ones when used on our larger turnstiles to allow for a more universal experience. Because of this, with a simple adapter plate (provided for no charge), an 8100 Series Control Head can be retrofitted with a new 6500 with ease.
While we try to support the 8100 Series Control Head, parts are very limited. Please contact us to see if we can provide you with replacement parts or suggest getting a 6500 Series Control Head instead.
The 1000 Series Turnstile & ADA Gate
The 1000 Series was a style of turnstile / gate that was constructed with a 4″ diameter tube and the controls were made to fit inside in a circular design.
While we still try to support 1000 Series units, parts are somewhat limited. We do not currently offer a replacement for 1000 Series controls.
Due to the unique design, it is usually best to ship 1000 Series controls into us for repair so that we can ensure the work is done properly.
Please contact us if you are in need of parts or service and we will try to help you the best we can.
The Classic Series CS-79 & HG-81
Created by Sentronic International back when our company was an OEM part manufacturer for them, the Classic Series turnstiles & ADA gates were a unique sand-cast aluminum pedestal with a compact control system. As we grew, Sentronic International eventually became a part of Controlled Access and we adopted the Classic Series for many years. Overtime, it became difficult to obtain some components for the internal control mechanism. As such, we decided to discontinue the model around the year 2007.
We do have a small supply of some replacement components for these units on the shelf if replacement parts are needed. If the rotary solenoids are not functional, we are unable to source replacements. While we can make no promises, we are glad to attempt to get these older heads functional again if they are shipped in for repair. Contact our sales department for more information.
Tiffany T-80 (Original)
The T-80 has been in production for a very long time. As another Sentronic International model, it had it’s own control system at one time as well. Modern T-80s all include a 6500 Series Control Head, and original release models can also be retrofitted with one as well.
While we have very little in terms of documentation and inventory available on this old control system, we do have some components on the shelf. Contact us if you need to order anything for the head and we can see if we can accommodate the request or at the very least make a recommendation to upgrade to the 6500 Series Control Head instead.
