                 Regarding the shutdown of fans in the fan coil unit by fire alarm


The FCU is fully controlled by unitary controller provided by BMS So  to shut down the fans FAS control module will connect to FCU controller this may be the proper way to control. Anybody have idea please share  .


Fire alarm input to FCU controller will override other commands.


In fm 200 protected area if BMS is controlling FCU from DDC instead of hardwire connection from FAS control module to FCU controller. What will be the shutdown time for FCU? Is it a standard???????????


In fm 200 area fcu fans shall be in off position with in 30s of detecting second stage alarm from FM200 detection.



Anybody have correct procedure with NFPA  or Saudi building Code reference ..Please share....
