2.7.8 Standby Power
Division 118 of the A17.2 Manual covers the annual full testing of standby (emergency) power
operation if this equipment is provided. The certified inspector must make himself familiar with
the stand by system provided for each individual elevator and devise a testing procedure
accordingly. The A 17.2 Manual describes procedures for testing two of the most common
2.7.9 Door Closing Force
Division 119 of the A17.2 Manual covers the testing of the closing force of the door system.
It is a simple test and it is a good practice to do it on each inspection. The codes require it to be
done at least annually, but it does not preclude it being done more often. Most elevator accidents
occur at the entrance. Therefore, extra effort on the inspection must be concentrated in this area.
2.7.10 Firefighter's Service Instruction Signs. Elevators installed under the requirements of the 1973 edition of the
A17.1 Code or later are required to have instructions for operating the elevator under the
Firefighters' Service permanently mounted adjacent to or incorporated with the switch at the
designated level. Elevators installed after the 1981 edition of A17.1 Code require that
instruction be posted at the designated level and in the car. The corridor instruction should
describe Phase I Emergency Recall Operation and the car instructions address Phase II
Emergency In-car Operation. one should check to see that these are in place and properly
displayed. Operational Testing. A full test of firefighters' service is required by Navy Criteria
every 60 days. Division 117 of the A17.2 Manual will describe the procedures for conducting
the full test. Operational Exercise. It is, however, recommended good practice to operate the system
periodically between tests. It has been found that exercising the system keeps it in good
operating condition and assures that it will operate at the time of an emergency. The test should
include activation of the lobby key switch to assure that all cars affected return under Phase I
requirements and that at least one car on Phase II operation is tested, if applicable. This would
include operating the Phase II switch in the car and moving it to a landing. Door operation
should be checked at this point. This simple test will exercise most of the operating circuits.
