NON-PROPRIETARY EQUIPMENT DEFINED
The words “Proprietary” and “Non-proprietary” have numerous descriptions, depending on whether or not your equipment IS one or the other, we suppose. In our industry, the following spec section is pretty much the standard definition of Non-Proprietary:
"All materials provided shall be serviceable by any Journeyman Elevator Mechanic, and, replacement parts for all equipment furnished shall be available on the open market. Access to diagnostic/troubleshooting routines shall require no secret codes. Provide any/all manuals, schematics, wiring diagrams and service manuals that are available to the manufacturer’s installers and service personnel. Any decaying circuits or devices requiring “factory re-charging” shall be considered a violation of this SPECIFICATION section; such equipment shall be removed and replaced with conforming equipment at no extra cost to the Owner. Technical help shall be furnished to the Owner, or Owner’s Agent as needed, for the life of the equipment. Controls must be of a type that does not require replacement of any other component (door operator, signal fixtures, etc..) in the event a controller replacement is necessary."
One of the big problems in this industry, especially in its current “internationalized” state, is that in many cases the major manufacturers’ equipment can only be maintained by their employees, using specialized diagnostic equipment, secret passwords and instructions only available to them (definition of Proprietary). Obviously, PM pricing can be a major issue when the Owner of the elevator has no options.
The equipment we install does not require any specialized diagnostic equipment, or, if it does, the device and complete instructions for its use are provided to the customer. Replacement parts for our equipment are available from numerous sources. The Owner owns the elevator, not us.
