RSB - Door Interlock
This interlock has two contacts, one for each
door, wired in series together as part of the safety
circuit. These contacts are made 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 stationary 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 stationary 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.
Emergency release of the interlock is made with
a KEB pull chain and box, seen on page 235 in
the accessories section.
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.
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 NEMA 9 (hazardous location)
applications.
