Product Description
Reliable Air Compressor panels provide a self-contained su-
pervisory air supply for single interlock preaction systems. The
air source for the Model B-SI is a 115-60-1, 1/16 HP Gast com-
pressor and the Model C-SI is equipped with a 220/230-50/60-1,
1/16 HP Gast compressor. A System Sensor PS10-2 pressure
switch monitors the system air pressure. Approximately 7 psi
(0.48 bar) of air will keep the pressure switch contacts open
and the air compressor off. A drop of approximately 2 psi (0.14
bar) will switch the contacts to the closed position and the com-
pressor will turn on to replace the air in the system ( in case of
a small leak). If the pressure drops approximately 3 psi (.021
bar) the low air signal will activate. The relay provides dry con-
tacts for remote signal of low air pressure or loss of power. The
hose kit (included with panel) provides flexibility to connect the
Model B-SI and C-SI Air Compressor Panel to the system. The
hose kit consists of a 1/4” shut-off valve, 1/4” x 72” stainless-steel
hose, 1/4” x 1/2” bushing, and 1/2” check valve. The check valve
must be installed horizontally at the opening provided for the
air supply on the system. The panel is designed with keyhole
slots for ease of wall mounting. A quick-fill bypass connection
outside the enclosure is provided to reduce system setup time
using an auxiliary compressor, if desired.
Caution: The pressure gauge shut-off valve must be closed
when using the quick-fill bypass. The quick-fill pressure must
not exceed 25 psi (1,7 bar).
Features
• Self-contained air supply.
• System low air indicator.
• Relay for remote signal of low air and/or loss of power.
• Bypass inlet and valve provided for quick filling system
with a separate source.
• Cabinet with keyhole slots for easy mounting.

The Reliable Model B-SI/C-SI Air Compressor Panel shall pe-
riodically be given a thorough inspection and test. NFPA 25,
“Inspection, Testing, and Maintenance of Water Based Fire
Protection Systems,” provides minimum maintenance require-
ments. System components shall be tested, operated, cleaned
and inspected at least annually and parts replaced as required.

Ordering Information
Specify:
• Model B-SI Air Compressor Panel (P/N 6702010003)
(120 VAC)
• Model C-SI Air Compressor Panel (P/N 6702020003)
(220 VAC)
Application
The Reliable Model B-SI and C-SI Air Compressor Panels are
designed and listed for use in installations governed by NFPA
13 to provide and supervise the air pressure required for single
interlock preaction systems. A 200 gallon system can be filled
in approximately 30 minutes. A bypass is provided for quickly
filling larger systems.
The Model B-SI and C-SI Air Compressor Panels should not be
used with dry pilot single interlock preaction systems. These
systems require substantially more air pressure than wet pilot or
electrically actuated systems. Refer to manufacturers informa-
tion for appropriate air supply for dry pilot actuated systems.
Installation
Location must be coordinated with, and installation made in ac-
cordance with, the requirements of NFPA 13 or NFPA 13R, and all
authorities having jurisdiction.
Check valve included with hose kit must be installed in the hori-
zontal position.
All electrical work must be performed in accordance with appli-
cable local and national codes.
Maintenance
The owner is responsible for maintaining all parts of the fire pro-
tection system in proper operating condition. Any system main-
tenance or testing that involves placing a system component
out of service may eliminate the fire protection that is provided
by the fire protection system.
Note: Relay contacts shown in alarm/loss of power condition for
remote monitoring.
