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.
