Ch 6 Sprinkler Systems and Standpipe Operations Flashcards
Sprinklers controlled or extinguished the fire more than how many percent? Pg 119
96%
What is a deluge system? Pg128
Consist of a piping system connected to a water source controlled by an automatic valve.
What is a preaction system? Pg 129
Consists of an automatic detection system coupled to an automatic dry pipe system. They are often installed over very expensive electronic equipment.
What is a automatic wet system? Pg 125
The most common and simplest type of sprinkler. This is a pipe system connected to a source of supply that has water in its piping at all times, right up to the sprinkler head.
What is a automatic dry pipe system? Pg 127
Is usually found in unheated areas. The pipes are filled with air either from a compressor or bottles and regulators.
What is a non automatic systems? Pg 130
System installed with no water supply other than the fire department Siamese.
What is a combination sprinkler and standpipe system? Pg 131
These systems were a logical way to extend sprinkler protection into existing unsprinklered high rise buildings.
If a building were built without sprinklers, the distance a person would have to travel to reach an exit is how many feet? Pg 132
100 ft
If the building is built with an automatic wet sprinkler system the distance to the exit should be how many feet? Pg 133
200 feet
What are class 1 standpipe systems? Pg143
Are those primarily used by the fire dept. They have 2 1/2 inch threads and are mainly used for fire dept to use their hose.
Riser control valves are required for every how many feet of height? Pg 143
150 ft
What are class 2 standpipes? Pg 144
They are used for building occupants to control minor fires until the fire dept arrives. They are provided with 1 1/2 inch hose. Can flow 100 gpm.
What are class 3 standpipes? Pg 144
It is designed to allow fire dept and occupant use.
When would a building need a standpipe? Pg 148
Any building more than 75 feet in height or more than 2 stories and 20,000 sq ft per floor.
