D. Proximity Door Protection Device

1. The passenger car door will be protected with a 36 or more, light-ray device extending to a height of approximately 5’ 0” above the floor. Interruption of one or more of the light rays will prevent the doors from closing or cause them to stop and reopen if they are in the process of closing. The interruption of the light rays will cause the doors to remain open as long as the obstruction is in the path of one or more of the light rays. The doors will start to close shortly after the obstruction is removed.

2. Door Noise: Door noise will be 50 dBA. This includes reversals.

3. Door Control & Closing:

c. A solid state, infrared passenger protection device shall be installed on the car door.

This device provides infrared light beams that create an invisible safety net across the elevator entrance. If these beams strike an object in the middle of the entryway, some of the light is reflected into special photo-diode receivers which scan into the entryway at a nominal 30 degree angle. If the receivers detect enough light, a reversal signal is generated to open the doors. The maximum projection of these 12 additional beams at any time is one-third of the door opening width.

d. If any beam is interrupted, the door-reversal signal will cause the elevator doors to reopen instantly without touching the passenger. After a car stop is made, the door shall remain open for a predetermined interval before closing. If, while the door is closing, the matrix of invisible light beams is interrupted by a passenger entering or leaving the car, the door shall stop and reopen, after which the door shall again start to close.

e. Graceful degradation operation is also included. If one or two isolated beams (up to a maximum of 36 beams) are interrupted, the door-reversal signal will cause the doors to reopen instantly. If the beams remain blocked for more than 80 seconds, the beams are considered permanently blocked.
