Dortronics' 4300 Series targets two-door applications

New brochure available at ASIS covers full line of controllers


Orlando, FL (September 19, 2011) -- Dortronics Systems, Inc. announces expansion of its line of door interlock and mantrap control products to include the New 4300 Series, a low-cost base model configured for standard two-door applications. A new multi-page brochure available at ASIS incorporates the Dortronics 4300 series along with the company's 4700 and 4900 series to provide customers a complete selection of door-control products ranging from simple two-door units to custom-programmable, 128-door, multifunction units. The brochure also highlights related products such as locks, switches, traffic lights and annunicator/control panels.

“The market is full of simple, two-door applications that can benefit from our new 4300 series, and release of this new technology at ASIS helps us fill the void at the lower end of our line with a solid product that does the job effectively for cost-sensitive applications,” said Bryan Sanderford, National Sales Manager, Dortronics Systems, Inc. “Our PLC-based controller products can handle any size door application, including air locks, clean room environments and security mantraps.”

Dortronics' 4700 series Mantrap Control systems are PLC-based controllers that can economically control up to four normally unlocked doors or three normally locked doors. The system provides six digital inputs, 2 DPDT Relay outputs and 2 SPDT Relay outputs, and customized sequencing and timing functions with the optional LED Display timer.

Dortronics' 4900 Series Interlock Control is designed to handle systems of over 100 doors. The PLC-based controllers can be programmed to operate doors with automatic openers and to provide custom-timing and logic sequences for biological wash-down and air purging controls. The series is available with 8-input/4-output modules and, optional 4-Relay output expansion modules. Custom sequencing and timing functions, and traffic light control for user feedback may be configured with the optional LED Display timer module.

Built-in power supply provides a field-selectable 12 or 24vDC output for the PLCs. This power can operate magnetic locks and/or strikes for doors, as well as LED indicators.
