NA7.14.1 Elevator Lighting and Ventilation Controls |
|
Use Document NRCA-PRC-12-F |
|
Purpose of the Test |
|
This test is to ensure that the shut off control turns off the lighting and ventilation fan when the elevator is not occupied for more than 15 minutes. The control system must be able to detect occupancy, and keep the ventilation fan on, in the event that someone is occupying the elevator cabin and the elevator conveyance or doors malfunction §120.6(f). |
|
Instrumentation |
|
This test verifies the functionality of installed automatic controls visually after a prolonged period of time. A clock or stopwatch will be needed. |
|
Test Conditions |
|
The test will be performed by varying the control parameters used by the elevator lighting and ventilation fan control system. Therefore, the elevator lighting and ventilation fan control system must be installed and operating, including completion of all start-up procedures per manufacturer’s or designer’s recommendations, to perform the test. |
|
Estimated Time to Complete |
|
Construction inspection: 15 min (for one system) |
|
Functional testing: 1 hour (for one system) |
|
Acceptance Criteria |
|
The elevator lighting and ventilation fan control systems must do the following: Turn off when the cabin doors have been closed for more than 15 Turn on when the elevator is activated Remain on after more than 15 minutes with the doors closed |
|
Potential Issues and Cautions |
|
Verifying the lighting and ventilation fans remain on with the doors closed for more than 15 minutes. |
A. Test Application
Newly Constructed Buildings and Additions/Alterations: Applies to functional testing and verification of the lighting and ventilation fan system controls.
B. Construction Inspection
The Field Technician must verify that the occupancy sensors have been installed in a location that will minimize false signals, such as pedestrian traffic in the elevator lobby. Also, if an ultrasonic sensor is being used the Field Technician must verify that the sensor does not emit an audible sound.
C. Functional Testing
Step 1: Open the elevator doors.
Verify and Document:
•The lighting and ventilation system turn on.
Step 2: Exit the elevator and allow the doors to close. After 15 minutes, open the elevator doors.
Verify and Document:
•The lighting and ventilation system were off and activated as the elevator doors open. If this method proves too hard to visually verify the lighting and ventilation system were off, then measure the power output of the elevator controls and verify that the lighting and fan power turns off after 15 minutes of being unoccupied.
Step 3: Enter the elevator cabin. Once the doors close, wait 15 minutes.
Verify and Document:
The lighting and ventilation system remained on after 15 minutes.
