"Complex security environments demand door control hardware that is adaptable, easy to integrate, and fully compliant," said John Fitzpatrick, President of Dortronics Systems, Inc during the show. "At ISC East, we’re showcasing an expanded portfolio of American-made solutions—from specialised interlocks and maglocks to customisable switches and control devices—designed to solve tough door-sequencing challenges while meeting NDAA and BAA standards."

48500-EZ PLC Interlock Controller

The new controller provides a single-board solution for managing two to five doors across one or two zones. Multiple controllers can be paired to support up to 10 doors across shared zones, with centralised lockdown capabilities.

It is field-configurable without external software, allowing integrators to customise door sequencing, alarm responses, security levels and overrides to meet specific application requirements across airlocks, clean rooms, data centres, schools and more.

In addition, the controller integrates with leading access control platforms, supports all door types and can monitor external threat detection systems, including tailgate alarms, metal detectors and duress alarms.
