The Design and Organization of Data Centers/Fire Protection
From Wikibooks, the open-content textbooks collection
Fire alarms systems are designed to detect and notify building occupants of a possible fire condition, so that proper reactive steps can be taken.
Some examples of fire alarm equipment include the following: Smoke Detectors Heat Detectors Beam Detectors Pull Stations Sprinkler System Monitoring Equipment Audible and/or Visual Notification Appliances

[edit] Sprinkler systems
Water and computers don't mix. A damaged sprinkler head will spray water regardless of a fire, and smoke detectors can be set off by dust.
Avoid sprinkler systems that hold water, instead use a pre-action sprinkler system, preferably a double-interlocked pre-action system. With a double-interlocking pre-action valve, water is prevented from entering the sprinkler piping until two different kinds of heat/smoke detecting devices trigger the valve to open. The typical devices used are pneumatic actuation by a sprinkler head activating and releasing pressurized air stored in the piping and an electric actuation from heat or smoke detectors.
