|How do they work??
|Fire sprinklers are only activated when the temperature in the room in which
a fire is burning exceeds the preset temperature of the sprinkler head —
nominally 135°F-165°F. Sprinklers operate as individual heat sensors,
meaning that water is only released in the area where there is a fire. They are
not activated by smoke. Often in a room with two sprinkler heads, only one
operates. Sprinklers typically deliver 25gal/minute (compared to 250gal/min
from a fire hose); systems are usually plumbed with copper pipe or rigid
CPVC pipe, fed off the rising main. Ideally, they require a 1 inch cold feed into
the house, as the systems need a good flow. This can be integrated with a
rainwater recycling system.
