122
Q

These valves prevent water from flowing into the piping until a sprinkler head is opened. The air pressures the system keeps the clapper closed. This clapper prevents the water from flowing into the system. When the sprinkler head opens it causes a drop in the pressure piping. This causes the valve to open and allows water into the system. Most of these valves are designed so that a moderated air pressure in a dry pipe system will hold back a much greater water pressure. When the clapper has opened the valve is said to have tripped, this valve is best known as (Notes —- Auto-dry sprinkler systems)

124
Q

Higher than normal water pressure or water hammer may cause the dry valve to _______________ by accident (Notes — Auto -dry sprinkler systems)

A

Trip

125
Q

Water hammer is caused by a sudden flow of a sudden change of water pressure in a dry-pipe system. To reduce this dangerous air pressure is usually kept well above the normal trip point. The air pressure is usually set at ___________ to ______________ psi above the normal trip level (Notes —- Auto -dry sprinkler systems)

A

15 to 20

126
Q

In a dry pipe system there is a delay between the opening of a sprinkler and the discharge of water. This delay may allow the fire to spread and more sprinklers to open. The delay is due to the time required for air to leave the sprinkler piping. This difficulty may be partly overcome by the installation of (Notes —- Auto -dry sprinkler systems)

128
Q

Accelerator and an exhauster are both automatically activated when a drop of _______________ psi in air pressure is noticed in the system.

Q

The following sprinkler systems are similar to the basic design of the dry pipe sprinkler system. These systems are called (Notes —- Auto -dry sprinkler systems)

A

Pre-action / Deluge / Non-automatic

130
Q

These systems are designed for situations where there is a danger of serious water damage. Water damage is usually caused by damaged sprinklers or broken piping. There is no este in the piping under normal conditions. The air in the piping is not under pressure. The valve prevents the aged from entering the system. The valve is automatically opened when a fire detections system discovers that there is a fire. This valve is tripped by the fire detection system before any of the sprinkler heads open. A supervisory device signals when the valve is opened. This valve can also be operated manually (Notes —- Auto -dry sprinkler systems)

A

Pre-action system

131
Q

The pre-action system has several advantages over a _______________ system. The pre-action valve open sooner because the fire detectors react to smoke and heat changes faster than sprinkler heads. Fire and water damage is decreased because water is sprayed on the fire more quickly an the alarm is given as soon as the pre-action valve is opened (Notes —- Auto -dry sprinkler systems)

A

Dry pipe

132
Q

Heat responsive devices are commonly used to trip pre-action valves. These devices are also used to activate alarm and supervisory systems. There are three main devices used to trip pre-action valves (1) devices designed to operate at fixed temperature (2) devices designed to operate when the temperature in the room increases a set amount in a five time period (rate-of-rise) and (Notes —- Auto -dry sprinkler systems)

A

Deluge

137
Q

The sprinkler heads in the ______________ system is not open at all times. Under normal conditions there is no water in the piping. The air in the piping is not under pressure. A closed control valve prevents water from flowing into the system. A fire- detection device signals when the valve is opened. When the valve is opened water flows into the system. The water is then sprayed out all of the sprinkler heads. The water control valve may also be opened manually (Notes —- Auto -dry sprinkler systems)

Automatic sprinklers are very effective for life safety. They signal the existence of a fire. At the same time, they discharge water to the burning area. When sprinklers are installed there are rarely problems getting to the seat of the fire. They also reduce interference with visibility with fire-fighting due to smoke. The downward force of the water sprayed from sprinklers lowers the smoke level in the room.
