Security Spotlight: Access Control

Access Control

Though Comtrol devices have had a consistent presence in the security market, many of Comtrol’s switches and gateways are used – and even specifically designed – for access control.

RocketLinx ACS7106

The RocketLinx ACS7106 is the industry’s first UL294/UL294B listed PoE switch that meets all state and local government requirements for access control installations. It is certified with Siemens and HID access control products, and features voltage boost technology (12-24VDC input power) for easy integration with fire/alarm/access control power systems.

What is UL294?

UL294 is the standard of safety for Access Control System units that all access control systems must meet. UL294B is a new subset of the UL294 standard, specifically for the use of Power over Ethernet (PoE) in access control systems where PoE is the primary power source.  These PoE devices are required to remain working normally through multiple rigorous tests in hazardous conditions in order to obtain the UL294B certification.  These tests consist of voltage/electrical variation, humidity, jarring, mechanical strength, temperature tests, etc.

Door Access Control System – DeviceMaster RTS


Access Control

Access control can be used in a variety of different ways from a lock on a car door, to a PIN on an ATM system, to a door control reader granting or denying access to a building.

In the door control industry a credential, such as a badge containing an RFID tag, is presented to a reader. The reader sends the information to a control panel, a highly reliable processor, and compares the credential’s information to an access control list and either grants or denies that person access to the building.

Within these access control applications there is a need to bridge the serial communication of the door controller into the network. Comtrol’s DeviceMaster RTS has been used to create this bridge in many different door control applications. The DeviceMaster RTS takes the serial information from the door controller, converts it and communicates to the control panel via Ethernet.

Companies rely on reliable and accurate access control to provide the safety and confidentiality that they need for their employees. The DeviceMaster RTS makes a good fit for door control applications because of its software-selectable RS-232/422/485 communication modes, ease-of –use and reliability.

Industrial Surveillance with Axis Communications – RocketLinx PoE


Establish consistent industrial surveillance through network camera control

Securing property such as manufacturing facilities and perimeters is essential to any industrial company’s asset protection system. Ideally, personnel would be monitoring the property consistently. However, combining essential pieces of equipment to form a comprehensive security system customizable to your surveillance needs provides a cost-effective solution to protecting valuable goods from theft.

Providing network video security solutions to a surveillance system can improve loss prevention by:

  • Automatically capture video when a perimeter is breached
  • Placing surveillance in areas not accessible to personnel
  • Accessing real-time video, even from remote locations
  • Identifying potential intruders

Using industrial outdoor cameras or network cameras with pan, tilt and zoom features in conjunction with Power over Ethernet (PoE) switches to control a security system greatly increases opportunities to utilize power and communication.

Industrial security monitoring

A surveillance system comprised of Axis cameras and Comtrol’s PoE switches provide benefits such as providing automatic alerts when someone enters a perimeter or restricted area, night vision and thermal images, HDTV-quality video images, and real-time access to live and recorded images. Axis’ easy-to-install, outdoor ready cameras and Comtrol’s ruggedized switches with drip-proof housings, redundant power inputs and performance command-line interfaces, combine to provide reliable networking solutions for industrial security monitoring.
