Original Press Release:



Dortronics Introduces New 4700 Series Mantraps at ISC West 2010.



o Economical PLC Door Interlock Controller Available in 4 Standard Configurations.

o Customization Options Available.

Las Vegas, NV - Today at ISC West 2010, Dortronics Systems, Inc. is introducing their cost-effective new 4700 Series mantraps. This flexible, versatile solution provides users with lower TCO (total cost of ownership) without sacrificing quality.

"At Dortronics we are committed to offering our clientele the most cost effective solutions," said Bryan Sanderford, National Sales Manager, Dortronics Systems, Inc. "Our 4700 Series PLC Mantraps ensure that customers do not have to compromise on quality while staying within a particular budget - a clear solution when purchasing high quality door controllers."

Offering secure interlock door control, the 4700 series provides one of the most economical solutions for small systems security. Suitable for air locks or security mantraps, with up to four normally unlocked doors or three normally locked doors, the PLC can be programmed at the factory to allow for only one door, in any defined area, to be unsecured at a time. A request for access at any normally locked door will inhibit the REX inputs for all other locked doors and secure all unlocked doors in the area. Simultaneous requests for access or requests for access while another door is unsecured are denied to maintain the highest level of control. The controller may also be customized to control automatic door openers and provide timing and logic sequences for biological wash-down controls.

Any access control system can be used with the 4700 Series controllers. The request for
access input recognizes any normally open dry contact. With integral 12/24 VDC power
supply, the PLC is powered from the built-in 4 amp power supply which also provides 12 or 24 VDC to operate maglocks and/or strikes for each of the doors. Its heavy-duty power supply is ready for hook-up to a fire alarm system and an alarm output is also supplied for easy monitoring of the control system.
