Which sprinkler system is designed for increased safety with a detection system?

The preaction system is specifically designed with increased safety features, incorporating a detection system that enhances its effectiveness in fire protection scenarios. This system is unique because it requires both heat and smoke detection to activate the water release, which means that water is only introduced to the piping when there is clear evidence of a fire. This dual-trigger feature prevents accidental discharge, which can occur in other types of systems.

The preaction system is particularly useful in environments where water damage from accidental activation could be as detrimental as the fire itself, such as in data centers, archives, and museums. The detection system provides an extra level of safety by ensuring that the sprinklers only operate in response to an actual fire, rather than just changes in temperature or pressure.

In contrast, other systems like dry-pipe systems and looped systems do not incorporate a detection feature that prevents unwanted water release, and while a gridded system ensures uniform coverage, it does not inherently include additional safety measures like a preaction system does.
