12. The Elevator Contractor shall provide a local car alarm signal and voice communication phone with automatic dialing device programmed to contact the Facilities Management (FM) Dispatch Elevator hotline, Housing and Dining Services dispatch line, or Colorado State University (CSU) Police Department.

a. Coordinate with the Project Representative for the phone number(s) of the appropriate destination.

b. Each elevator phone shall provide a caller ID that shows the building name or address and the elevator number.

c. The outgoing phone call shall connect directly to the receiving phone without any automatic recording.

d. Coordinate with Project Representative to determine whether building is equipped with Voice Over Internet Protocol (VOIP).

13. Elevator pits shall be constructed to keep groundwater out of the pit.

F. ADA Standards/Other Uses:

1. Elevators shall comply with National Electrical Illumination Institute (NEII) “Suggested Minimum Passenger Elevator Requirements for the Handicapped” which shall include door time adjustment and Braille pads.

2. Hall call and car operating panel buttons shall be a flat–faced, protruding stainless steel button style with a square shoulder.

a. All buttons shall have square shoulders, be 3/4” (19.1 mm) minimum in the smallest dimension and shall be raised 1/8” (3.2 mm) plus or minus 1/32” (0.8 mm) above the surrounding surface.

b. The buttons shall be activated by a mechanical motion that is detectable.

c. Buttons that are compliant with California Title 24 Section 11B–407.2.1.2 are acceptable.

3. At least one elevator shall be for moving freight or sized for combination freight/passenger.
