“Non-Proprietary” Defined

It is the Commitment, Not the Equipment that differentiates Non-Proprietary from Proprietary. Contractors, manufacturers and elevator professionals suggest that all elevator control systems are basically Proprietary in nature, by virtue of their design.

The degree of Proprietary Restraint can be measured by the ability of service companies other than the original control manufacturer to maintain the equipment – and the degree of Proprietary restraint within distribution and support channels.

Freedom of choice is the reason most often mentioned by building owners when specifying Non-Proprietary elevator control equipment. The ability to select from among competitive maintenance providers, if necessary, ensures the sound financial future increasingly in demand by decision makers. The MCE Bill of Rights for Building Owners establishes performance standards against which all equipment can be measured for freedom from Proprietary restraint.
