New expansion modules available for Dortronics' 4900 Series mantrap systems

Dallas, TX (October 12, 2010) - Dortronics Systems, Inc. is showcasing new expansion modules for their popular 4900 Series Intelligent Interlock System today at ASIS 2010. The modules increase the number of relay outputs per module, allowing system designers to build upon the standard mantrap configuration and program additional interlock configurations or operation requirements such as switching lock power, traffic lights, sounders, cameras, or signaling a central console. The 4900 Series Controller provides easy expansion for a virtually unlimited number of controlled portals, and can provide timed responses for the sequencing of peripheral equipment, such as blowers, lighting or decontamination systems.

"Customization is paramount in today's marketplace, and Dortronics strives to meet the needs of almost any operational requirement," said Bryan Sanderford, National Sales Manager, Dortronics Systems, Inc. "The 4900 Series Mantrap with Expansion Module can be easily reprogrammed to accommodate future expansion or changes in functionality with additional input/output modules."

Each 4900 Series I/O module can control up to four normally locked doors, eight normally unlocked doors or a mix of locked and unlocked doors utilizing the 8 available inputs. Each board provides 8 inputs (typically used for the door switch and request-to-exit switch for each door); 4 DPDT form C Relays providing 8 dry contact outputs (4 fused and 4 un-fused); 4 digital outputs that can be used to drive signal lights directly or may be used to operate up to four additional relays if needed; 4 voltage out terminals and 4 common returns for powering locks, lights or external circuits.

"We designed the 4900 Series to be compatible with any access control system or standard manual switch controls. It can be used with any electrically operated locking devices to control automatic door operators, air misting/purge systems, LEDs for traffic indicators and monitoring controls," concluded Samderford.

The 4900 Series PLC can be expanded to accommodate in excess of 128 inputs and 128 outputs. Its modular design enables control of any sized door interlock project with standard input/output modules and expansion relay modules providing cost-effective configurations for most mantrap designs. Additional standard and special-order modules can be combined to provide custom solutions.
