FM-200 : suppressed area / nozzle ?

FM-200 : suppressed area / nozzle ?

FM-200 : suppressed area / nozzle ?

(OP)
What is the recommended nozzle placement distance for FM-200 system in a computer room (12x7 m)?

According to ISO 14520:
"The type number and placement of nozzles shall be such that:
the design concentration is achieved in all parts of the enclosure;..."

How many nozzle is recommended to be installed?
Should each lane between the server rack rows be suppressed? Is it OK to install a nozzle roughly every 6 m (for instance), taking into consideration the objects in the flow of agent's path, and modifying the placement according to that?
May the subfloor area suppressed by fewer nozzles if not too crowded with cables?

RE: FM-200 : suppressed area / nozzle ?

Nozzle placement is a function of the listing. You need to research the design manual for the manufacturer of the equipment and determine proper placement based on the hazard classification and agent.
