i have x-ray room inside hospital ,and the owners want to install fm200 system within this room , is that allowed
Normally there is a pre alarm, before the system dumps. This should alert people to leave.
Hopefully it is not a mri room or similar, where it takes awhile to get someone out
FM-200 is safe for use in occupied areas at the design concentration. It is a colorless, odorless agent vaporizes upon discharge and absorbs heat to rapidly suppress fire while leaving no residue to clean up. It is electrically nonconductive, will not short-out electronic equipment or thermally shock delicate circuitry. The fire itself may have done that before the clean agent is released.
My experience with the activation of the these system is they mostly activated by mistake from facility staff that does not know how the system operates. They hear the general fire alarm system and think they have to pull the manual station to activate the system. The system goes off expelling all the clean agent. Aftermath, they realize their mistake and find the that recharging them has some significant costs.
These systems do not provide any more fire protection then a wet automatic sprinkler system for the life safety of the occupants. In my opinion, the x-ray equipment circuits are already toasted when the system detects smoke and finally activates. An appropriate clean agent portable extinguisher used by staff at the immediate instance of smoke may be a better option to protect some of the circuits. Many hospitals in my jurisdiction do not installed them because of the significant costs to maintain them.
I am sure the owner has some sort of justification to install the system.
