HR-1 Door Interlock: Left Hand (A) - Standard Heavy Duty |
Double Contact 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.
