You will need to check section 2.27.3.1.6 sub section C. This is for phase 1 operation.

I unfortunately do not have the 2013 code. 2010 says it must be inoperative and in 2016 it must NOT be rendered inoperative

In 2010 code, it is said A moving
car shall have the in-car stop switch and the emergency
stop switch in the car when provided, rendered inoperative
without delay.

In 2016,(c) When provided, the in-car stop switch (see
2.26.2.21) or the emergency stop switch in the car (see
2.26.2.5) shall not be made ineffective
