34.Notification time to FDNY for an out of service condition - ANSWER ✔ 8
hours
35.Who must draw a hand drawn sketch of the compactor system - ANSWER
✔ Certificate of fitness holder
36.Upright Sprinkler - ANSWER ✔ A sprinkler designed to be installed in
such a way that the water spray is directed upwards against the deflector.
37.Water Spray Fixed System - ANSWER ✔ A special fixed pipe system
connected to a reliable fire protection water supply and equipped with water
spray nozzles for specific water discharge and distribution over the surface
or area to be protected. The piping system is connected to the water supply
through an automatically or manually actuated valve that initiates the flow of
water. An automatic valve is actuated by operation of automatic detection or
manual release equipment installed in the same areas as the water spray
nozzles. (In special cases, the automatic detection system may also be
located in another area.)
, 38.PREACTION SPRINKLER SYSTEMS - ANSWER ✔ designed for
situations where there is danger of serious water damage. Water damage is
usually caused by damaged sprinklers or broken piping. Under normal
conditions there is no water in the piping. The air in the piping may or may
not be is under pressure. A preaction valve prevents the water from entering
the system. The valve is automatically opened when a fire detection system
discovers that there is a fire or smoke condition. The preaction valve is
tripped by the fire detection system before any of the sprinkler heads open.
A supervisory device signals when the valve is opened. The preaction valve
can also be operated manually.
39.DELUGE SPRINKLER SYSTEMS - ANSWER ✔ equipped with open
sprinkler heads designed to wet down an entire area involved in a fire. This
system is needed when there is danger of a fire rapidly spreading throughout
the building. The deluge system will slow down the spread of the fire.
Deluge systems are suitable for hazardous occupancies. This includes
buildings in which flammable liquids or other hazardous materials are
handled or stored.
The sprinkler heads in the deluge system are 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 automatically opens the control valve when a
fire is identified. A supervisory device signals when the valve is opened.
When the valve is opened water flows into the system. The water is then
discharged out all of the sprinkler heads. The water control valve may also
be opened manually.
40.NON-AUTOMATIC DRY SPRINKLER SYSTEMS - ANSWER ✔ ll
pipes are normally dry. Water is supplied when needed by pumping water
into the system through the Fire Department connection. Some of these
systems are supplied by manual operation of a water control valve and may
be equipped with sprinklers with or without fusible links.
There are several non-automatic systems: 1) Perforated pipe systems - a
single line of piping drilled at intervals for water discharge. These systems
are usually found in basements or other areas difficult to reach in fire
fighting operations. 2) Open fixed spray nozzles for transformer vaults or
other hazardous areas; 3) exterior exposure sprinklers (or window sprinklers)
use open sprinkler heads to form an external water curtain on the walls of a
