Dortronics introduces 4700 Series Mantraps with LED digital displays

Las Vegas, NV (April 6, 2011) – Dortronics Systems, Inc. is introducing their cost-effective new 4700 Series mantraps here at ISC West 2011. Offering secure interlock door control, the 4700 series provides one of the most economical solutions for small security systems. Suitable for air locks or mantraps with up to four normally unlocked doors or three normally locked doors, the PLC is factory programmed and tested to permit only one door to be unsecured at a time. This flexible and versatile solution provides users with lower TCO (Total Cost of Ownership) without sacrificing quality.

"Like Dortronics’ comprehensive core lineup of products, our new 4700 Series PLC Mantraps deliver advanced performance and reliability at a very competitive price point – without sacrificing quality," said Bryan Sanderford, National Sales Manager, Dortronics Systems, Inc. "The functionality of the 4700 Series PLC Mantraps makes them ideal for numerous applications in any size system configuration."

A request for access at any normally locked door with the 4700 Series 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.
