Elevator Codes and Standards © 2015 Eaton. All Rights Reserved. .

Applicable Requirements NFPA 13 requires sprinklers in elevator shafts (with some exceptions) and in elevator equipment rooms. ANSI/ASME A 17. 1 Safety Code for elevators requires that power to an elevator be shut down prior to the release of water in the elevator shaft or electrical equipment room. NFPA 72 The National Fire Alarm Code requires: Control circuits to shut down elevator power shall be monitored for the presence of operating voltage. Loss of voltage to the control circuit for the disconnecting means shall cause a supervisory signal to be indicated at the control unit and required remote annunciation. © 2015 Eaton.

NEC® Section 620. 51(A) states: (A) Type. The disconnecting means shall be an enclosed externally operable fused motor circuit switch or circuit breaker that is lockable open in accordance with 110. 25. The disconnecting means shall be a listed device. Informational Note: For additional information, see ASME A 17. 1 -2013/CSA B 44 -10, Safety Code for Elevators and Escalators. © 2015 Eaton.

NEC® • Section 620. 51(B) states: • (B) Operation. No provision shall be made to open or close this disconnecting means from any other part of the premises. If sprinklers are installed in hoistways, machine rooms, control rooms, machinery spaces, or control spaces, the disconnecting means shall be permitted to automatically open the power supply to the affected elevator(s) prior to the application of water. No provision shall be made to automatically close this disconnecting means. Power shall only be restored by manual means. • Informational Note: To reduce hazards associated with water on live elevator electrical equipment. © 2015 Eaton. All Rights Reserved. . 9

NEC® • Section 620. 51(C) states: • “Location. The disconnecting means shall be located where it is readily accessible to qualified persons. ” • “Within Sight of the elevator controller” © 2015 Eaton. All Rights Reserved. . 10

Back-up Power Requirements NFPA 70 The National Electrical Code requires disconnect switches for elevators with backup or auxiliary power (where the backup power is connected on the load side) to be equipped with auxiliary contacts to disconnect the backup power system. 620. 91 (C)Disconnecting Means. The disconnecting means required by 620. 51 shall disconnect the elevator from both the emergency or standby power system and the normal power system. Where an additional power source is connected to the load side of the disconnecting means, which allows automatic movement of the car to permit evacuation of passengers, the disconnecting means required in 620. 51 shall be provided with an auxiliary contact that is positively opened mechanically, and the opening shall not be solely dependent on springs. This contact shall cause the additional power source to be disconnected from its load when the disconnecting means is in the open position. © 2015 Eaton. All Rights Reserved. . 11
