Final answer:
Emergency elevator operation for both Phase 1 and Phase 2 should be tested annually to ensure safety compliance and reliability in the event of an emergency, such as a fire.
Step-by-step explanation:
Phase 1 and phase 2 emergency elevator operation should be tested annually and whenever there are changes or updates to the elevator system. This testing ensures the reliable performance of the elevators during a potential emergency, such as a fire. In Phase 1, the elevator is recalled to a designated floor, typically the ground floor, and cannot be used until reset by firefighters or maintenance personnel.
This phase is activated by smoke detectors or fire alarms in the building. Phase 2 is the operation by firefighters or emergency personnel from within the elevator, allowing them to use the elevator to reach different floors safely. It's crucial to regularly test these systems to comply with codes and safety regulations.Emergency elevator operation for both Phase 1 and Phase 2 should be tested annually to ensure safety compliance and reliability in the event of an emergency, such as a fire.
