1- General description
This
T
OTAL
P
AC
®

integrated fire protection system by
F
IRE
F
LEX
Systems Inc. consists of a preaction system trim
totally pre-assembled, pre-wired and factory tested. All
electrical and mechanical components of the system are
contained in one single unit.
Note:
Skid units include the trim components only and must
be wired by the installing contractor.
The only connections required for installation are the water
supply inlet, the water discharge outlet, the main drain, the
pneumatic release inlet, the electrical supervisory and
alarm connections, as well as the AC power line for the
optional air compressor. The discharge outlet is
connected to a fixed piping network of automatic
sprinklers, in parallel to the pneumatic release piping
network (pilot line). Water is the extinguishing agent.
On system piping network and pneumatic release piping
network, closed heat sensitive automatic sprinklers are
spaced and located in accordance with recognized
installation standards in order to detect a fire. Only those
sprinklers immediately over or near to fire operate,
minimizing water damage.
Non interlock preaction system with pneumatic release
uses closed automatic sprinklers on the system piping
network, which is supervised with air pressure. A
pneumatic release piping network is installed in parallel
with the system piping network and is designed to operate
before an automatic sprinkler fuses from the system piping
network. Pneumatic release system operates first and
gives a supervisory signal.
Non interlock preaction system is designed so the deluge
valve will open when either a loss of pressure from the
pneumatic release piping network or from the system
piping network occurs. When the deluge valve opens,
water will flow into the system piping network and out of
any open automatic sprinklers and other opening on the
system.
In the event of no operation of the pneumatic release, the
system will operate as a dry system. In the event of
damage to the system piping network or an automatic
sprinkler, the deluge valve will open. Water will flow from
any open automatic sprinklers and any other opening in
the system piping network.
Note:
Every

unit is identified with its unique
serial number. This number is located on an adhesive
label inside the main door panel and is used to maintain a
record in our computerized data base. Have this serial
number handy when calling for information on your unit
(format is TOT3#### or TOTS#### for skid units).
