184.108.40.206.5 General Earthquake Mode Elevator Operations (See Figure 220.127.116.11.3)
(a) When the counterweight displacement detection device is actuated, operation of the car by means of the key described in 18.104.22.168 and 22.214.171.124, hospital emergency service key, and other similar types of operation is prohibited.
(b) Elevators with power-operated doors, upon reaching a landing, shall cause their doors to open and remain open, except that where Phase II Emergency In-Car Operation is in effect, door operation shall conform to 126.96.36.199.
(c) Upon activation of an earthquake protective device, an elevator standing at a floor with its doors open shall remain at the floor with its doors open. If its doors are closed, it shall open its doors. Where Phase II Emergency In-Car Operation is in effect, door operation shall conform to 188.8.131.52.
(d) An elevator not in operation when an earthquake protective device is activated shall remain at the landing.
(e) Elevators stopped by an earthquake protective device with a volatile-type memory shall remain idle in the event of a power failure. Subsequent restoration of power shall not cancel the status of the earthquake protective devices nor the slow-speed status of the elevator system if such existed prior to the loss of power.
(f) An elevator shall be permitted to be returned to normal service by means of the momentary reset button or switch [see 184.108.40.206.1(d)], provided the counterweight displacement detection device and the seismic detection device are not actuated.
