Dortronics Systems, Inc. (www.dortronics.com) unveiled its new cost-effective 4700 Series mantraps. It is a flexible, versatile solution that provides machine 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, Dortronics’ National Sales Manager. “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.”
The 4700 series offers a secure interlock door control, one of the most economical solutions in the world for small systems security. It is suitable for security mantraps or air locks with up to three normally locked doors or four normally unlocked doors. The programmable logic controller (“PLC”) can be programmed in the factory to only allow one door, in any determined area, to be not secured at a time. One request for access in any locked door will inhibit Request-to-exit (“REX”) inputs to secure all unlocked doors and for all other locked doors in the area. Requests for access for unsecured door and simultaneous requests for access are denied to maintain a high-level of control. Also, the controller may be customized for automatic door openers and to provide logic and timing sequences for biological wash-down controls.
Using the 4700 Series controllers can access any control system. The access input’s request recognizes any open dry contact. The PLC is powered with integral 12/24 V DC power supply from the built-in four amp power supply that also provides 24 or 12 V DC to operate maglocks and/or strikes for each of the doors. The controller’s heavy-duty power supply is setup for integration to a fire alarm system and an output alarm is supplied to easily monitor the control system.
