Hi Friends, In factory non fire fighting related power will be shutted down automatically or manunally once fire happen? Locally ( in China) normaly should be automaticaly through fire alarm addressible module but I am not sure how to achieve this in NJ of U.S. Thanks!

Are you asking if it is required? or if it can be done/how to do it? or if it is typical in the states?

In a commercial setting, there are no general electrical code or building code requirements in NJ to shut down general building power on activation of the fire alarm system. There are specific exceptions; kitchen range hoods come immediately to mind. You should analyze each process to determine if there is an increased hazard if it remains energized during a fire. In some circumstances, shutting down a process suddenly may be more dangerous than allowing it to run, or sending a shutdown command to the process controller for an orderly shutdown rather than an emergency shutdown.

You would use a fire alarm control unit addressable control module to operate a shut trip breaker or a contactor to remove power from the process, if emergency shutdown is considered necessary.
