Final answer:
The coordinators should use the floor alarm method to notify occupants on multiple floors.
Step-by-step explanation:
The coordinators of fire safety and alarm systems should use the floor alarm method to notify occupants of a smoke/fire condition on the floor of the alarm, the floor immediately above, and the floor below.
The floor alarm method involves activating the audio and visual devices simultaneously on the respective floors.
This ensures that occupants are alerted and can take appropriate action.
For example, if there is a smoke/fire condition on the 3rd floor, the alarm devices on the 3rd, 2nd, and 4th floors would be activated to notify occupants on all three levels.
