FireFlex TOTALPAC2 Quick Start Manual

Air Supply Section
Preaction, dry valve and other sprinkler systems using air
pressure for supervisory or releasing purposes are provided
with either internal or external supervised air supplies.
Four (4) styles of air supplies are available for the
T P 2 units depending on needs or configurations.
OTAL AC
These air supplies are all factory assembled, mounted in the
cabinet and pressure tested. They are all located in the top
part of the cabinet, hung on mounting rails above the valve
trim. Here is the description of those options:
Air Option "A": (Refer to Figure 1) Used only for the
sprinkler piping network of electrically operated preaction
systems and with dry pipe systems. Air option "A" includes
the air compressor mounted inside the T
with its supervisory trim and options. Compressors are of the
oiless piston type without reservoir and are factory piped to
the sprinkler piping system riser, all within the T
cabinet. They are available in four (4) sizes;
1/6HP
1/3HP
All the above air compressors have open, single phase
motors with internal thermal protection and can be ordered in
two supply voltages settings:
120Vac-60Hz or
The 120Vac-60Hz is the normal voltage used in Canada and
the United-States while the 220Vac-50Hz is primarily used in
Europe, Middle-East and other countries with 220 volts, 50
cycles current.
Air Option "B": (Refer to Figure 2) Used only for the
sprinkler piping network of preaction or dry pipe systems,
when an external air supply is provided by others (either
compressor, plant air or dry nitrogen cylinders) and piped to
the air inlet port of the unit. Air option "B" provides an Air
Pressure Maintenance Device (APMD) trim, factory mounted
in the T P 2 cabinet.
OTAL AC
Note: For the releasing system piping of pneumatically
actuated systems, use air supply type "C" or "D" below
(with an external air compressor).
Air Option "C": (Refer to Figure 3) Used only for the
pneumatic release piping network of pneumatically operated
preaction or deluge systems. An external air supply has to
be provided by others (either compressor, plant air or dry
nitrogen cylinders) and piped to the air inlet port of the unit.
Air option "C" provides an Air Pressure Maintenance Device
(APMD) trim, factory mounted in the T
Air Option "D": (Refer to Figure 4) Mainly used with
preaction systems protecting refrigerated spaces and
freezers, where a special dry external air supply unit is piped
directly to the system riser inside the freezer itself, as shown
in NFPA-13. Provides only an air supervisory and shut-off
trim.
Ambient temperature at the special external air supply unit
location should not exceed 104

refrigerated spaces applications. Air option "D" can also be
used when the contractor prefers to provide his own air
supply & regulation trim, mounted outside the T
cabinet.
Note: When Air Options "B", "C" or "D" are selected, the air
supply should be provided and installed by the sprinkler
contractor OUTSIDE of the T
provided with the unit.
1. Air supply design and selection:
The air
automatically establish the total required air pressure in 30
minutes. External air supply should be provided with an
Air Maintenance Device (Air Option "B") to regulate and
restrict the flow of supervisory air into the sprinkler system
piping.
Note: External air supply MUST always be restricted to
insure that the automatic air supply cannot replace air as

Note: Selection of the proper air compressor size is the
responsibility of the installing contractor.
2. Connecting the Air Compressor to AC power
(Air option "A" only):
The motor must be protected against short circuit, overload
and excessive temperature rise.
switches and thermal protective switches provide the
necessary protection in these circumstances.
Fuses only serve as a short circuit protection of the motor
(wiring fault), not as protection against overload. Those are
provided and wired by the electrical contractor. An isolation
switch (for location detail, refer to Figure 2 in CONTROLS
Section) is also provided in the T
factory wired, allowing powering off the air compressor while
some maintenance work on the unit is done, without
disturbing the rest of the system.
Note: The air compressor is separately pre-wired to its own
set of field wiring terminals identified TBB in the
T P
OTAL AC
depending on the enclosure configuration selected. These
terminals must be wired to a separate and properly sized
fuse or circuit breaker, different from the control panel
