If you specify a rescuvator, you must also specify a disconnect switch with an auxiliary contact that opens when the disconnect arm moves to the open position, but stays closed when the OCPD trips. This list includes but is not limited to passenger elevators, freight elevators and escalators. If you are looking into information on emergency phones, its worth getting some context on all emergency response options at a high level. The same figure applies to nonmetallic wireways. Many new buildings are incorporating an elevator design that does not include an equipment room (sometimes called machine room-less elevators). For more information on how Kings III can keep you code-compliant, visit www.kingsiii.com. Requirements in Article 620 modify the articles in Chapter 3. The two main types of elevators are hydraulic and traction. Second, it must be configured so as to eliminate any chance of tangling or chafing against the inner surface of the hoistway or items mounted on it. Hydraulic elevators comprise a hydraulic reservoir, pump, cylinder, and controller. Machine room-less elevator installations incorporate the elevator controller and often the primary disconnecting means in a convenient package that is located within the elevator shaft. If this is not done and the available fault current exceeds the elevator controller SCCR, other solutions to reduce fault current must be reviewed or equipment changes and field evaluations may be needed. Elevators are found in almost all new buildings that are greater than one story. With respect to such Occupancy Groups B, E and R-1, the following equipment, where such equipment is required by this code, shall be provided with an emergency power system: Exit signs and means of egress illumination required by Chapter 10; Elevator car lighting; This will normally require you to vent the room with a fire/smoke damper and include smoke detector signals in the control logic. The elevator controller manufacturer must determine the required elevator controller SCCR as stated in the elevator controller specification and provide an elevator controller SCCR that is equal to or greater than the available fault current thats indicated in the design documents where there are multiple elevator controllers at different locations.
