Construction
The Red-E Cabinet is constructed of a
minimum thickness of 14 gauge steel,
and is free standing. The standard
paint finish is bright red and black. The
front doors of the enclosure are fully
hinged and removable and open nearly
to the cabinet floor level, allowing easy
access to the couplings when connect-
ing the water supply and drain.
The compressor is stored near the
bottom of the cabinet on a pull out
drawer for access through the double
doors. Pre-drilled holes on tabs along
the base provide an anchor point for the
cabinet to be secured to the floor when
required. Industrial grade rollers at the
bottom of the cabinet are standard.
Internal controls that provide functions
to reset a system after operation, for
example, alarm test valve, main drain
valve, are individually tagged for easy
identification. All prefabricated piping
is Schedule 40 steel.
A splash-resistant drain cup is pro-
vided that ensures water does not
splash into the cabinet during flow
testing. The discharging water can be
observed through a clear tube attached
to the drain cup. It is designed with a
fail-safe feature allowing water to over-
flow in the event the drain is blocked.

TYPICAL ASSEMBLY ARRANGEMENT
(2 IN. DELUGE SYSTEM WITH ELECTRIC ACTUATION SHOWN)
The hard piped funnel drain is con-
nected through a swing check valve to
the main drain header, eliminating the
need to run a separate drain line from
the funnel. The cabinet floor is provided
with a drain opening to allow water to
drain out. A plug is also provided to
prevent water from draining from the
cabinet if necessary.
For dry pilot trim arrangements, the air
supply connection for cabinets without
compressors (that utilizes AMD-1) are
terminated at a common height across
all model sizes allowing the connec-
tion of groups of cabinets easier. This
allows a single tank mounted compres-
sor sized to meet the requirements
of the largest system in the group to
supply all the cabinets in the group, or
alternatively, connect to the factory air
supply. The air supply line contains a
tee and plug which is used to connect
a hydraulic test pump that pressurizes
the sprinkler system above the butterfly
valve for hydraulic testing of the system
in accordance with NFPA 13.
Table A provides a list of riser compo-
nents and a cross reference to indi-
vidual technical data sheets, as well
as individual component laboratory
approval information.
Figure 1 provides dimensional infor-
mation for Red-E Cabinets, and Figure

arrangement.

Considerations
The open nozzles and/or sprinklers, fire
detection devices, manual pull stations,
and signaling devices that are to be uti-
lized with the Red-E Cabinet must be
UL Listed, ULC Listed, C-UL Listed, or
FM Approved, as applicable. With ref-
erence to Figure 3, the system designer
must consider and make preparations
for use of a Red-E Cabinet as follows:
• Adequate floor space to facilitate
opening of the cabinet doors
• Minimum ambient temperature of
40°F (4°C)
• Installation of a suitably sized water
supply to the water supply header
(Port B, Figure 1)
• Installation of system piping (Port A,
Figure 1) including open nozzles and/
or sprinklers from the Red-E cabinet
outlet
• Installation of drains from main drain
header (Port C, Figure 1)
• Installation of the detection system
components and alarms
• Power supply to Red-E Cabinet
• Separate power supply to the air
compressor (dry pilot actuation)
