Q

The construction techniques used in these buildings built after 1968 resulted in a “lightweight”
building, usually weighing about 8 to 10 pounds per cubic foot.
name 4 features ?

A

1.The method of securing exterior curtain walls leaves a space of 6 to 12 inches
which requires additional fire stopping.
2. The ceiling plenums of these buildings are extensive and lack fire stopping.
They are used to return the air to the air-conditioning system and for electrical,
communications and other building support equipment

Q

How is the bypass valve located on a fire pump ?
The bypass valve shall be in what position ?
How is it closed ?

A

Located on the discharge side of the fire pump.
The discharge side can be readily identified by examining the gauges.
The discharge gauge is calibrated for higher pressures than the inlet gauge
The bypass valve should be in the closed position (stem in).

Q

Some systems are quite complex and the bypass valve is not readily
discernible. If such a situation is present, it is permissible to start pump as
ordered without checking bypass valve
Why is checking of this valve so important ?

A

The efficiency of the pump will
be affected if the bypass is open. A loss of 25% can be expected in an 8”
riser and a loss of 45% can be expected in a 6” riser with the bypass open
remember the rule of “15”: 2+5+8=15 and 4+5+6=15
