A office manager is telling their staff to allow wheelchair bound persons access to the elevator during a fire as long as office personnel inform firefighters on the egress floor. This is a non-ambulatory office building on a hospital campus. Is this valid?

Click to view contentWe built a new hotel and connected it to the existing hotel. The new hotel has its own fire pump and distribution line. The existing hotel has standard response sprinklers.   Can we adopt 9.4.3 (5) and install standard response to the new hotel?       Big thanks for your input.
