HR-1 Door Interlock
This interlock is specifically designed for
mounting to cement or cinder block wall or
anywhere where the lock must fit around a
ninety degree edge. It has two contacts, wired in
series together as part of the safety circuit. The
upper is the door contact, the lower is the locking
contact which is both electrical and mechanical.
When the door is closed the upper (door) contact
is made.
When the retiring cam is retracted the bottom
contact is made and the locking bar goes into the
catch on the door edge, mechanically locking the
door. When the car stops at a floor the retiring
cam pushes the release roller, mechanically
unlocking the door and opening the bottom
electrical contact. When the door is opened the
top contact drops by gravity. Although this is
designed for use with a retiring cam it can be
used with a stationary cam .
When ordering specify hand. The hand is
determined by standing inside the elevator
looking out. The side on which the lock is to be
mounted (left or right) is the hand to be ordered.
