    Distributor Inventory

    Honeywell Relialign™ CDI Series Residential Door Interlock switches are electromechanical devices designed for use in swing door applications, specifically dumbwaiters, material lifts, lifts for the mobility impaired and private residence swing-door elevators in the USA. In Canada, the CDI is designed for use in swing door applications, specifically dumbwaiters, material lifts, and residential elevators, but is not designed for use in lifts for the mobility impaired. The interlock holds the door in place and prevents it from being opened in potentially unsafe conditions (e.g. the elevator/lift car is not present at the door).

    CDI Series interlocks are configurable and available in left- and right-hand versions, allowing for simplified installation, customization, and retrofi tting into current designs. 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.
