SDC - Door Interlock
Same as the RSB except for use with a retiring
cam. This interlock has three contacts, one for
each door and one for the retiring cam, wired in
series as part of the safety circuit. The door
contacts are made when the doors are closed; the
retiring cam circuit contact is made when the
cam is retracted. 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 now 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
pushes the roller assembly, unlatching the safety
link. When the door bars are manually lifted
they release the hook latch assembly and the
doors can be opened.
When ordered complete, the interlock comes
with one straight drive bar, offset drive bar and
pickup roller assembly (dimensions from data
sheet prepared by customer), two locking bar
assemblies and one door handle to be mounted
to the active door on the hall side of the door.
A data sheet showing door height, width,
thickness, running clearance, corner offsets and
depth of jamb must accompany the order.
These interlocks can be made with hermetically
sealed contacts for NEMA 4, 12 (water/dust
resistant), or C1,D2 (hazardous location)
applications.
