3.2.8 IT and electrical plant rooms
IT and electrical plant rooms, in which power supply equipment, control systems, security systems and computer
servers are accommodated, are risk areas that need to be especially well protected.
Aspirating smoke detection systems (ASD) are able to detect extremely low smoke concentrations which may be
caused, for example, by a malfunction of an individual electronic component. It may then be possible to prevent
fire developing simply by removing the power from the particular unit.
Automated dry extinguishing systems (i.e. systems using inert gases or clean agents) provide a best fit for the
protection of delicate and expensive electrical and electronic equipment and prevent costly business interruptions.
It has been shown that the performance of hard disk drives (HDDs) can be disturbed by the high noise levels that
can occur during the discharge of dry extinguishing systems. However, by selecting the appropriate extinguishing
system and nozzle as well as implementing silent extinguishing measures, noise-induced disruptions to hard disk
drives and entire storage systems can be minimized.

and “Fire protection in server rooms”.
