5516N: Interlock control board for 2 doors

The 5516N  is a self-contained 2 door interlock. Additional boards can be linked together to configure a multi door interlock with no limit to the number of doors.
There are 2 operating modes, the original Secure Locked Mode where all doors start locked and a request to open the door is made via the ‘Exit’ Terminals. These boards also have the Unlocked Open Mode where all doors start unlocked and when you physically open any door the other doors lock.  If the interlock controller has the Unlocked Open feature both Status lights will light when you power the board. We recommend the Secure option as this cannot be breached however depending on the locking device used it may be possible to open more than one door at the same time using the Unlocked mode.
