20–32

Page 33: Systems and detection goff

Sprinkler systems are made up of several components.

20–33

Page 34: Systems and detection goff

Sprinklers are fixed spray nozzles that operate to discharge water.

20–34

Page 35: Systems and detection goff

All of the common release mechanisms for sprinklers respond to heat.

20–35

Page 36: Systems and detection goff

Sprinkler deflectors create the discharge pattern of water downward.

20–36

Page 37: Systems and detection goff

Sprinkler storage cabinets are usually installed near a riser or valve.

REVIEW QUESTION

What types of smoke control systems can be used at an incident?

20–63

Page 64: Systems and detection goff

• Many buildings are protected, partially or fully, by fire protection systems that range from simple to complex.

• These systems can perform a variety of functions and it is important that these are identified during pre-incident surveys to ensure firefighters understand how to operate in these structures.
