"Honeywell Relialign™ CDI Series Residential Door Interlock switches are electromechanical devices designed for use in swing door applications, specifi cally 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, specifi cally 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). Featuring a custom internal solenoid control mechanism that uses Honeywell MICRO SWITCH™ switches, the Relialign™ Series of door interlocks may reduce complexity of the host controller, reduce power consumption, extend solenoid life, and reduce solenoid timeouts. CDI Series interlocks are confi gurable and available in left- and right-hand versions, allowing for simplified installation, customization, and retrofitting into current designs."
