What if the required conditions in the buildings when replacing Sprinkler firefighting system in the administrative offices with a different system?

Thanks to the Majdi Quick Answer. I would like to add to your answer some important details when you replace the fire-fighting system. with a FM200 system must used be replaced windows of the building office with a good isolation windows to ensure that no gas leakage to outside the building.

in case of replacing FM200 system instead of sprinkler system may be some of the following procedure can be taken:

- placing the control panel & provide electrical source & a connection to the main fir alarm panel

- fined a place out side the space for the gas cylinder

- doors must close automatically in case of fire ( signal from FM200 control panel or main panel )

- if there is a ventilation fans or fresh air it must be stopped or at list add a motorized volume damper 

- some projects we add a fan to purge fire gases
