The Relialign CDI commercial door interlock switch is offered by Honeywell Sensing and Control as an alternative to large, installation-intensive interlocks and OEM custom-made products.
Ideal for applications including commercial swing-door elevators and platform/vertical lifts, the switch holds the swing door in place and prevents it from being opened when not desired, such as when a platform lift is not present at the door.
Safety features include a door-closure retention cam, metal key operation, internal solenoid control, and no open or exposed contacts. It can be installed unobtrusively, without requiring damage to the door or frame during installation.
