Honeywell Relialign™ CDI Series Commercial Door Interlock switches are designed for commercial swing door interlock applications, including elevators, dumbwaiters, and platform lifts. This lift or elevator door interlock holds the door in place and prevents it from being opened when not desired (e.g. the elevator/lift car is not present at the door) by employing solenoid switch circuit technology. A number of design features in the elevator interlock contribute to increase safety, reduce nuisance stoppages and call-backs, and contribute to simplified wiring and installation.
Featuring a custom internal solenoid control, the CDI Series interlock switch can reduce complexity of the host controller, reduce power consumption, extend solenoid life and reduce solenoid "time outs," reducing customer aggravation. Two snap-action basic switches are used to indicate door closure, providing an extra level of reliability.
Reliability and smooth operation are also enhanced by the use of a metal key that is less susceptible than a plastic key to bending and breakage. The lack of open or exposed contacts minimizes the possibility of owners making manual adjustments. Finally, the engagement of the key initiates electrical contact.
The snap-action cam mechanism reduces adjustment set-up time and reduces door movement that can cause nuisance shutdown. An RJ-45 Category 5 connector option is available, simplifying installation. This door interlock is configurable and available in left- and right-hand versions, allowing for simplified customization. It is designed to be easy for the OEM to retrofit.
