Preaction System
Preaction systems are designed to protect water-sensitive areas such as freezers,
museums, computer rooms, and clean rooms. These locations contain
water-sensitive equipment, precious objects, or are sensitive areas where
accidental water discharge is undesirable. Preaction systems may take the
place of dry systems.
A pre-action fire sprinkler system is a two-step process requiring two separate
devices to be activated before the sprinkler heads release water. The first step
is to trigger the fire detection system, which can be done through smoke
detectors, heat detectors, or a combination of both. Once the fire detection
system has been activated, water is released into the pipes. The second step is
for the fire sprinkler head/s to activate and suppress the fire.
One of the main benefits of a pre-action fire sprinkler system is that it
provides a high level of reliability and protection against false alarms. The
two-step process ensures that water is only released in the presence of an
actual fire, which reduces the risk of water damage from false alarms.
