## NA7.15 Escalator and Moving Walkway Speed Control

### NA7.15.1 Construction Inspection

Verify and document the following prior to functional testing:

(a) Variable speed drive is installed on the escalator.

(b) Occupancy sensor has been located to minimize false signals.

(c) Occupancy sensors do not trigger from pedestrians on adjacent escalators.

(d) Occupancy sensors do not encounter any obstructions that could adversely affect desired performance.

(e) Ultrasonic occupancy sensors do not emit audible sound

### NA7.15.2 Functional Testing

For each escalator or moving walkway being tested, confirm the following:

(a) Verify the amount of time necessary to ride the entire length of the escalator while standing still.

(b) Stand away from the escalator. After being in an unoccupied condition for more than three times the length of time for a full ride, the escalator should slow down.

(c) Approach the escalator entrance while in an unoccupied condition from multiple angles to ensure passenger detection cannot be bypassed.

(d) Verify the slow speed setting is 10 ft/min.

(e) Verify the full speed setting is below 100 ft/min.

(f) Verify the acceleration and deceleration of speed changes. The acceleration shall not exceed 1 ft/sec sq.

(g) Approach the escalator in an unoccupied condition at an average walking pace. The escalator should reach full speed before boarding.

(h) Approach the escalator in an unoccupied condition at an average walking pace. The escalator should reach full speed before boarding. An alarm should signal to alert that the pedestrian is approaching in the wrong direction.
