Ensure strict security and controlled entry with the Dortronics 43211-L 4300 Series 2-Door Mantrap Interlocks, an access control panel engineered for high-risk entry points. Designed as a 2-door / 1-room, normally locked door interlock system, this controller sequences door operation to prevent tailgating and enforce single-occupant access—ideal for data centers, laboratories, evidence rooms, and clean rooms. The 43211-L pairs with the included 4204NX 4A UL Listed Class 2 power supply, providing selectable 12 or 24 VDC to operate maglocks or strikes while remaining ready for fire alarm hookup.

A built-in Emergency Release delivers immediate egress by unlocking one or both doors when required, balancing security with life-safety compliance. Rugged, compact (15" x 12" x 4") construction ensures easy installation in a variety of environments.
