Q

What activates a pre action sprinkler system?

A

2
The preaction system is similar to a dry-pipe system but is considered slightly more efficient. This system is used where an alarm in advance of sprinkler operation is desired, and where it is particularly important to prevent accidental discharge of water.
In a preaction system, heat or smoke detectors are installed throughout a protected area. When a detector actu-ates, an automatic water control valve admits water through sprinkler piping, where it remains until a sprinkler head op-erates.

55
Q

Let’s look at each type of soil. Type __ soil is cohesive and has a high unconfined compressive strength; 1.5 tons per square foot or greater.

A

Type A

56
Q

Type ___soil is cohesive and has often been cracked or disturbed, with pieces that don’t stick together as well as Type ___soil. Type __soil has medium unconfined compressive strength; between 0.5 and 1.5 tons per square foot. Examples of Type —-soil include angular gravel, silt, silt loam, and soils that are fissured or near sources of vibration, but could otherwise be Type

A

Type B as compared to type A

57
Q

Type ___ soil is the least stable type of soil. Type __includes granular soils in which particles don’t stick together and cohesive soils with a low unconfined compressive strength; 0.5 tons per square foot or less. Examples of Type ___soil include gravel, and sand. Because it is not stable, soil with water seeping through it is also automatically classified as Type __soil, regardless of its other characteristics.
