Tone Alert (Piezo)
•
On trouble conditions, the tone-
alert sounder is on steady to indicate
that a trouble has occurred. It turns
off when ACCEPT SIGNAL KEY is
pressed.
•
On alarm conditions, the tone-alert
pulses until the ACCEPT SIGNAL
KEY is pressed.
Environmental
This equipment operates normally
within the temperature range of 32°F
to 120°F (0°C to 49°C), inclusive. This
equipment operates normally under
non-condensing humidity conditions
up to 93% humidity at 90°F (32°C).

Assembly
The Manifold Assembly (Figure 2) is of
brass and bronze construction.
Trip Ratio
When applying a water delivery cal-
culation program for determining that
the water delivery will not exceed 15
seconds, the trip ratio of the Model
RCP-1 Panel must be entered into the
program. The trip ratio for the Model
RCP-1 Panel is determined by dividing
the available static water supply pres-
sure by 7 psi. The use of 7 psi is based
on the tolerance of the system alarm
trip/release pressure, where 7 psi is the
lowest potential trip pressure. For ex-
ample if the available static water sup-
ply pressure is 30 psi, the trip ratio is 30
divided by 7 (that is, 4.3:1). For an avail-
able 130 psi static water supply, the trip
ratio is 130 divided by 7 (that is, 18.6:1).
Operation
The system is automatically maintained
at a normal system air pressure of 10 to
14 psi (0,7 to 1,0 bar) via the Air Com-
pressor Switch/Air Compressor (Fig-
ure 2). In the standby condition, water
is prevented from entering the system
piping until the Solenoid Valve in the
Manifold Assembly is opened in re-
sponse to the electronic control.
The operation sequence is listed below.
•
The normal standby condition is AC
green light ON.
•
Closure of Main Control Valve, clo-
sure of System Control Valve, or a
high system pressure condition re-
sults in a supervisory condition
(SPM1).
During a Supervisory Condition, the
Yellow SUPERVISORY LED flashes
and the tone-alert sounds steady.
After accepting, the tone-alert si-
lences and the Yellow SUPERVISO-
RY LED stays ON until the condition
clears.
•
Opening of a sprinkler results in a
low air condition of less than nom-
inally 8 psi (0,6 bar) resulting in an
alarm condition ON IDC1, opening of
the Solenoid Valve (RAC1), and op-
eration of alarm notification devices
(NAC1).
During an Alarm Condition, the Red
ALARM LED, corresponding to Zone
or SPM in alarm, flashes and the
tone-alert pulses. After accepting,
the tone-alert silences and the Red
ALARM LED stays ON until the alarm
condition clears.
