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,
pressor and the Model C-SI is equipped with a 220/230-50/60-1,
/
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 " shut-off 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).
