The elevator car shall be of such a size and arrangement to accommodate an ambulance stretcher 24 inches by 84 inches (610 mm by 2134 mm) with not less than 5-inch (127 mm) radius corners, in the horizontal, open position and shall be identified by the international symbol for emergency medical services (star of life). The symbol shall not be less than 3 inches (76 mm) in height and shall be placed inside on both sides of the hoistway door frame.

• 4 or more stories above or below grade plane.
• 3 stories or less in height in buildings of I-1, I-2, I-3, and R-4 occupancy.

• have a rated sound pressure rating of not less than 80 dBA nor greater than 90 dBA at (10 ft)

Vertical Changes in Level: Changes in level up to 1/4 inch (6.4 mm) high maximum are permitted to be vertical (Section 303.2).

Beveling [ADA 303]:

The 2010 ADA Standards for Accessible Design specifies beveling requirements for changes in level on accessible routes.
The relevant section is 303 Changes in Level, specifically 303.3 Beveled:

• Vertical Changes in Level: Changes in level up to 1/4 inch (6.4 mm) high maximum are permitted to be vertical (Section 303.2).

• Beveled Changes in Level: Changes in level between 1/4 inch (6.4 mm) high minimum and 1/2 inch (13 mm) high maximum shall be beveled with a slope not steeper than 1:2.

Canting [ASME A17.1   2.1.6.2]:

• Other than separator beams between adjacent elevators, all projections/recessions 4 inches or greater in depth and greater than 1 inch in width are to be beveled at an angle of not less than 75 degrees.

Quick math: for 75° angle: Find your pocket depth. tan(75) * depth = height canting needs to be taken to. depth / cos(75) = hypotenuse, overall length of the canting material.

Note: Vent must be mechanically held open and powered shut. Vent must open when the elevator enters fire service.

If water can hit our controller and/or machine the following are required:

• Heat detector, located within 2 feet of the sprinkler head. Must be set to a lower temperature rating than the sprinkler head.

Electrical:

Disconnects

Disconnect working space  NFPA 70 – 110.26 (A)(1), (A)(2), (A)(3).
depth; Live to ungrounded Live to grounded Live to live 0v-150v 36” 36” 36” 151v-600v 36” 42” 48” Note: concrete, brick and tile walls are considered grounded.
width; Equipment width or 30”, whichever is greater. Must permit a minimum of a 90 degree opening of doors/panels.
height; 78” or equipment height, whichever is greater.
Disconnect fusing:
120v disconnect fuse/breaker must be 15 ampere. NFPA 70 - 240 (D)(3). Neutral MUST NOT be fused. NFPA 70 - 240.22. Note: All primary elevator companies ship traveling cables with 14 AWG wiring for their 120v circuit.

Illumination/GFCI:
Pit Duplex receptacle, 125v single phase, 15 or 20 ampere. Dedicated branch circuit - Pit Pit: 10 fc at the pit floor [ASME A17.1   2.2.5]. Dedicated circuit (pit lights and GFCI may share a dedicated circuit as long as the lighting is not tied into the load side of the GFCI)  Pit light switch readily accessible from terminal door.
Machine space / Control space ICS hoistway overhead: Duplex receptacle, 125v single phase, 15 or 20 ampere. Dedicated branch circuit - Machine space ICS hoistway overhead: 19 fc on the overhead equipment and the cartop when it is placed into the lowest locking bar position [ASME A17.1   2.7.9.1]. Dedicated circuit (overhead lights and GFCI may share a dedicated circuit as long as the lighting is not tied into the load side of the GFCI) Hoistway light switch readily accessible from terminal door. ICS: Top terminal lobby; 19 fc at the sill with the light switch on (control room space) [ASME A17.1   2.7.6.3.2 (c)]. Dedicated circuit - Control space ISC:  Light switch must be in the lobby. Note this is separate from and in addition to the hoistway light switch. Machine/Control room: Duplex receptacle, 125v single phase, 15 or 20 ampere. Dedicated branch circuit - Machine/Control room Machine/Control room: 19 fc at the floor level [ASME A17.1  2.7.6.3.2 (c)]. Dedicated circuit (Machine room lights and GFCI may share a dedicated circuit as long as the lighting is not tied into the load side of the GFCI) Machine room light switch within easy reach at point of entry.
Lobbies Landing sills: 10 fc [ASME A17.1   2.11.10.2]. Landing sill of the top floor of an ICS must still be 10 fc with the light switch off (public space).
Elevator itself Car threshold: 5 fc with the door closed [ASME A17.1   2.14.7.1.2] [ADA 2010   407.4.5]. Dedicated circuit - Elevator Car auxiliary (emergency) lighting: 2 fc in front of the primary COP [ASME A17.1   2.14.7.1.3 (a)].
The state has recognized the particular circumstances surrounding MRL elevators (ICS in Kone's case) in regards to 2007 code. When the in-wall controller is in the open position, it is recognized as control space and must be treated as such. Caveat being when the in-wall controller is closed the area is recognized as public space. As a result, both code sections must be complied with.

Smoke detectors:

Lobbies:

• Each lobby must have an initiating device.

• Location: Horizontal plane; within 21' --- Vertical plane; ceiling height equal or less than 15'

• Note: If a lobby contains more than 1 smoke detector, only 1 of them is required as an initiating device as long as it is within the location scope of all elevators in the bank (21'/15'). The rest of them need only be general area detectors.

NFPA 72 - 21.3.5 A lobby smoke detector shall be located on the ceiling within 21 ft (6.4 m) of the centerline of each elevator door within the elevator bank under control of the detector. Exception: For lobby ceiling configurations exceeding 15 ft (4.6 m) in height or that are other than flat and smooth, detector locations shall be determined in accordance with Chapter 17.

• If ceiling height is greater than 15' a wall mounted smoke detector is normally installed within 60" above the entrance. Note: code only dictates close proximity, newer code states 60" which is what the inspectors like to go by as a reference point.

NFPA 72 (2010) - 17.7.3.1.4* If the intent is to initiate action when smoke/fire threatens a specific object or space, the detector shall be permitted to be installed in close proximity to that object or space.

• Reasoning: due to the recognition of smoke stratification: (where smoke stops rising because it loses buoyancy).

Machine Room/Space; Control Room/Space:

• One must be present

ASME A17.1 (2007) - 2.27.3.2.1 In jurisdictions not enforcing the NBCC, fire alarm initiating devices used to initiate Phase I Emergency Recall Operation shall be installed in conformance with the requirements of NFPA 72,and shall be located (a) at each floor served by the elevator (b) in the associated elevator machine room, control space, or control room (c) in the elevator hoistway, when sprinklers are located in those hoistways

Hoistway (shaft):

• If this is a MRL (Machine Room-less elevator[ICS]) a smoke detector MUST be installed at the top of the hoistway. This is machine space and trumps NFPA 72 - 21.3.6

NFPA 72 - 21.3.6 Smoke detectors shall not be installed in unsprinklered elevator hoistways unless they are installed to activate the elevator hoistway smoke relief equipment.

In general:

Airflow near smoke detectors:

• Smoke detectors must be clear of HVAC registers by a minimum of 3’.

NFPA 72 - 17.7.4.1* In spaces served by air-handling systems, detectors shall not be located where airflow prevents operation of the detectors.

• Even though specifically 3’ does not exist for commercial, Authority Having Jurisdictions (AHJs) recognize and enforce the minimum of 3’ based off residential code.

NFPA 72 - 29.8.3.4 Specific Location Requirements. (6) Smoke alarms and smoke detectors shall not be installed within a 36 in. (910 mm) horizontal path from the supply registers of a forced air heating or cooling system and shall be installed outside of the direct airflow from those registers.
