Fire Suppression System

1. The high-piling of combustible material at sprinkler heads is undesirable principally because

• sprinklers fail to operate

• water cannot reach the seat of the fire

• there is more content capable of burning

• more smoke will be produced

When a fire occurs under a sprinkler system, sprinklers operate

• all sprinklers in the room in which the fire occurs

• only those which are heated to fusing temperature

• all sprinklers on the system

• only one

It is the most common type of fire sprinkler head that extends downward from piping.

• Upright sprinkler head

• Pendant sprinkler head

• Sidewall sprinkler head

• None of the above

When a fire-protection installation is supplied from a low-pressure water source, the system requires this type of pump to raise the pressure in the water- supply line.

• Jockey Pump

• Sump Pump

• Fire Pump

• Booster Pump

This is used in a fire-protection installation to maintain a constant, predetermined pressure in the sprinkler system and/or at the hose stations and to compensate for minor leaks from the system.
