Elevator hoistway door interlocks are intended to prevent the operation of the driving machine by the normal operating device unless the hoistway door is locked in the closed position, and to prevent the opening of the hoistway door from the landing side unless the car is within the landing zone and is either stopped or being stopped.

Retiring cams are not covered under this category, and their acceptability must be determined at the point of installation by the Authority Having Jurisdiction.

Elevator hoistway door combination mechanical locks and electric contacts are intended to prevent operation of the driving machine by the normal operating device unless the hoistway door is in the closed position, and to lock the hoistway door in the closed position and prevent it from being opened from the landing side unless the car is within the landing zone.

Elevator hoistway door, car door or gate electric contacts are intended to prevent operation of the driving machine by the normal operating device unless the door or gate is in the closed position.
