Final answer:
All elevators equipped with firefighter service are required to undergo a phase I and phase II test. Phase I verifies key safety features, while phase II simulates a power failure to test evacuation procedures.
Step-by-step explanation:
All elevators equipped with firefighter service shall be subjected to a test of phase I and phase II. Phase I of the test involves verifying that the elevator's key safety features are functioning properly. This includes checking the emergency lighting and communication systems, as well as ensuring that the elevator can be controlled from the firefighter's panel. Phase II of the test involves simulating a power failure to assess the elevator's ability to safely evacuate occupants during an emergency.
