Details: Dortronics 4300 Series Economical Mantrap Controller, 2 Door, 1 Room

The 4300 series door interlock controller provides an economical solution for simple interlocks. This unit is configured to allow only one door, in a 2-door vestibule, to be unsecured at a time. The second door is secured and inhibited from opening while the first door is accessed to maintain the highest level of control. Suitable for air locks or security mantraps, this controller can be field configured as both doors normally unlocked or normally locked or one door locked and one unlocked. There is a built-in Emergency Release function that can unlock one or both doors regardless of door status.

Any access control system can be used with the 4300 series controllers. The request for access input recognizes any normally open dry contact. The door unlock sequence will follow the status of the request for access input. The 4300 is paired with a 4204NX 4 amp UL Listed Class 2 power supply which also provides 12 or 24 VDC to operate maglocks and/or strikes for each of the doors. The heavy-duty power supply is ready for hook-up to the fire alarm system. An alarm output is also provided for monitoring the power system.
