Description
Secure Interlock Door Control
The 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.
Environmental or Security 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.
Access Control Compatible
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.
Integral 12/24 VDC Power Supply
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.
