Door Controllers

Security door controls come in a variety of products, but they essentially establish a system by which a group of people can enter a given door. Whether that given facility has chosen to utilize an access control system beyond the basic electronic or deadbolt lock, these security door controls add a further layer of security that can protect fraudulent or forced entry. As a second layer of security, we understand that is important to have high functioning, quality materials, and our inventory reflect that need for our customers. Please browse our inventory and see which product best meets your needs.

  1. Keri Systems NXT-4D NetXtreme 4 Door TCP/IP Controller

    Keri Systems NXT-4D NetXtreme 4 Door TCP/IP Controller

    The NXT-4D Xtreme 4 Door Controller is built for today’s IT environments. With all Ethernet functionality built directly into the controller, Keri’s proprietary MAC address allows for reliable hardware discovery and true 1 button autoconfiguration. By using an existing TCP/IP network, controller cabling costs can be eliminated, or by using inexpensive unshielded CAT5 cable if building a new network they can be reduced up to 50% over traditional hard-wired access systems. The NXT-4D is designed to be extremely intelligent with little reliance on network traffic for decision making allowing it to be extremely thrifty with any network’s valuable bandwidth To expand the system’s capabilities, up to four companion 4 x 4 Input/Output boards (NXT-4X4) can be added - one to each of the controller’s RS-485 trunks (busses). Customers can choose between Keri’s new line of highly secure, 4-wire NXT Proximity Readers with reader supervision, and any reader with a standard Wiegand output or Keri’s MS Series Proximity Readers via the NXT-RM Reader Interface Module. To manage the system, Doors NetXtreme software has much of the same look and feel as Keri’s acclaimed original DoorsTM software, but with the added functionality of Client/Server architecture.

Door Access Control

An access power controller, similar to the Altronix ACM and AL series that we offer, converts AC/DC inputs into independent fuse controlled outputs. This essentially means that the given system is routing power to different door control hardware, that can include things like maglocks, keypads, and electric strikes. 

These accessories are especially important for multi-door systems, because they help increase the given bandwidth of a facility for independent, unified control over a multi door system. This feature also allows for alarm monitoring.

The AL power controller has the extended feature of turning those inputs into Fail-Safe/Fail-Secure outputs, which allows for further peace of mind when dealing with building security so highly related to the power source. The ability to disconnect individual outputs from the fire alarm also adds the safety of emergency exiting procedures in the event of a problem.

Code Keypads

Code keypads and control panels also allow for you to give broader security for those who are entering various secure rooms. These keypads have the optional add on of a prox card reader, in the even that you may want to grant limited access to certain individuals, or protect your key code in various environments. 

Our keypad products, like the Alarm Lock NETPDKPAK, is compatible with most HID prox cards and keyfobs, and allow for varying customization and security privileges, such as multilevel access control.

Power Supplies & Transformers

Our control panel power supplies and power transformers, such as the Camden Invision CV-32H1, creates an online distributed processing access control system, that can be set up over an internet based network, giving you unified control over multiple buildings with minimal infrastructure overhaul. 

In some cases, this can be upwards of 128 doors, which is useful in applications like hospitals and universities. Additionally, these systems and power supplies allow for features like battery-backup and remote dialup. The software featured with such products allows for further customization and expanded options like photo import and customizable IDs.
