The 4300 series 2-Door interlock controller is an inexpensive alternative for two door mantraps. It features
two powered relay outputs for direct connection to locks and traffic lights. It may be easily configured during
installation for locked, unlocked or locked-unlocked operation by means of jumpers. It includes an override
function to unlock one or both doors remotely, bypassing the interlock.
