Honeywell Announces Addition to Relialign(TM) Residential Door Interlock Switches That Feature Rugged, Plastic Housing

Relialign(TM) RDI2 Series' Effective Design Contributes to Its Enhanced Safety, Reduction of Nuisance Stoppages, and Callbacks

MINNEAPOLIS - Honeywell's (NYSE: HON) Relialign(TM) Series of residential door interlocks now includes the RDI2 Series, engineered with a rugged, plastic housing. Designed specifically for residential swing door applications, the RDI2 Series joins an established product line of metal-housed products released in 2009 (RDI Series).

Honeywell's Relialign(TM) door interlocks hold the door in place and prevent it from being opened when not desired, such as when the elevator/lift car is not present at the door. A number of design features, including a door-closure retention cam, contribute to RDI2 Series' enhanced safety, reduction of nuisance stoppages, simplified wiring, and ease of installation. Reliable and smooth operations are enhanced by the use of a metal key that is less susceptible than plastic to bending and breakage. The lack of open or exposed contacts minimizes the possibility of owners making manual adjustments.

Featuring a custom internal solenoid control, Relialign(TM) RDI2 Series interlocks can reduce complexity of the host controller, trim power consumption for a "greener" product, extend solenoid life, and reduce solenoid "time outs," lessening customer aggravation. RDI2 Series Residential Door Interlocks include a manual override for easy actuation without user hazard, which reduces the potential for call-backs.

To meet customer and industry requirements, the Relialign(TM) Series is compliant with ASME A17.1, UL Standard 104, and CSA-B44.1. Potential applications include residential elevators, dumbwaiters, and platform/vertical lifts.
