Device Description
Double Swinging Doors - SDC Interlock - Retiring Cam Required
The SDC is a true elevator door interlock retiring cam required device. It has three electrical contacts, two for each door and one center one for door locking. It must be used with a retiring cam and wired per the controller companies instruction. These contacts are wired in series together as part of the safety circuit. These contacts are made up when the doors are closed. The interlock mounts horizontally on the top center jamb where the doors meet. Each door has a locking bar assembly vertically mounted, consisting of a bar and a locking hook latch. When the door is closed the locking hook latch engages the door contact drive, mechanically latching the door, and closes that door contact. When both doors are closed and latched the elevator is set to run. When the roller assembly leaves the retiring cam the safety link rotates into the hook latch assembly on the active door preventing door opening while the car is in motion.
When the car stops at a floor, the retiring cam stationary cam pushes the roller assembly, unlatching the safety link and opening the center contact. This signals the controller that the door is unlocked. This allows the active door handle to turn and lift up the door keeper, allowing the door to open. The inactive door is opened by reaching in and pulling the inside door bar up allowing the door bar latch to exit the lock as the door opens.
When ordering specify hand. The hand is determined by standing inside the elevator looking out. The side on which the zone control is to be mounted (left or right) is the hand to be ordered.
