Residential Dry Pipe System
General
Description
The TYCO Residential Dry Pipe System
provides a normally dry system for
areas subject to freezing or areas
that may be inadvertently subject to
freezing.
The key components of the Residential
Dry Pipe System are:
• Model RCP-1 Residential Control
Panel
• Residential Sprinklers specifically
Listed for use in residential dry pipe
systems (versus being limited to wet
pipe systems only)
• TYCO CPVC Pipe and Fittings made
with BLAZEMASTER Compound
• SprinkFDT Fluid Delivery Calculation
Software
Typically, residential sprinklers based
on their Listing are limited to wet pipe
sprinkler systems to assure speed of
water delivery for a prescribed design
area (the number of design sprinklers).
The Model RCP-1 Residential Control
Panel, in combination with specic
Residential Sprinklers listed for use in
dry pipe systems, provides options for
areas sensitive to freezing.
To achieve UL Listing, the Residential
Sprinklers have undergone rigorous
testing to meet UL1626 re test crite-
ria, including a 15-second delay for
water delivery as required for residen-
tial sprinklers intended for use in dry
pipe systems.
NOTICE
The Residential Dry Pipe System
described herein must be installed
and maintained by qualified personnel
in compliance with this document, and

impair the performance of this device.
The owner is responsible for maintain-
ing their fire protection system and
devices in proper operating condition
and in compliance with all applicable
standards and requirements. Contact
the installing contractor or product
manufacturer with any questions.
Do not disconnect batteries or turn off
AC power to quiet unwanted alarms.
The Model RCP-1 Panel will not operate
(that is, release water or energize
alarms) if AC power is not connected,
has failed, or has been interrupted
for any reason and the battery is dis-
connected, drained, or improperly
connected.
The use of an automatic sprinkler
system does not allow for omission of a
Household Fire Alarm System installed

ture, type of piping, and water supply.
See Figure 4 for appropriate sprinkler
selection and piping arrangements.

TFP485
Page 3 of 12
• SYSTEM RELEASED
The red SYSTEM RELEASED LED
turns on steady when the RAC cir-
cuit is activated. Activation of the
RAC circuit energizes the Solenoid
Valve to permit water to enter the
sprinkler system piping. RAC1 is
utilized, and RAC2 is spare.
• EARTH FAULT
The yellow Earth Fault LED turns on
steady when there is a wiring fault
from circuit to Earth.
• LAMP TEST
A lamp (LED) test can be per-
formed by pressing and holding the
ACCEPT SIGNAL key for a duration
of ve seconds. Performing a lamp
test lights all LEDs on the system
and allows verication that all sys-
tem LEDs are functioning.
KEYS
• ACCEPT SIGNAL
The system LEDs (ALARM, SUPER-
VISORY, and TROUBLE) ash to
indicate the presence of an unac-
cepted alarm, supervisory, or trou-
ble condition somewhere in the
system. The ACCEPT SIGNAL key
acknowledges the presence of an
alarm, supervisory, or trouble con-
dition. By momentarily pressing the
ACCEPT SIGNAL key, the ash-
ing LED turns steady. The ACCEPT
SIGNAL key is used to acknowl-
edge every abnormal status present
in the system. For example, if there
are two red alarms and three yel-
low troubles, the ACCEPT SIGNAL
key must be pressed ve times. The
panel’s tone-alert (piezo) turns off
when all abnormal conditions are
accepted.
• SIGNAL SILENCE
Pressing the SIGNAL SILENCE key
silences the audible notication
devices (horns). The yellow Alarm
Silenced LED lights to indicate that
an alarm is still active even if the
audible alarms have been silenced.
• SYSTEM RESET
Pressing the SYSTEM RESET
key directs the panel to reset
all attached devices and clear
all accepted alarms, troubles,
and supervisory conditions. All
alarms must rst be accepted via
the ACCEPT SIGNAL key and all
devices must be reset (normal sys-
tem air pressure re-established).
Note: After pressing the SYSTEM RESET
key, the panel requires approximately
fifteen seconds to clear.
Notification Appliances
NOTICE
NFPA 13D does not require the instal-
lation of a waterflow alarm (notification
appliance device).
Notication appliances can be installed
to indicate release of the Model RCP-1
Panel.
When installed, notication appliances
must be installed in accordance with the
applicable requirements of NFPA 72.
Per the requirements of NFPA 72, re
warning equipment for dwelling units
shall provide a sound that is audible in
all occupiable dwelling areas.Operator
Interface
The Model RCP-1 Panel uses LEDs and
keys as its primary means of display-
ing status information and controlling
the system. It allows the occupants to
monitor the status of the Model RCP-1
Panel and its circuits.
The Operator Interface is organized
with the LEDs located along the left and
right sides and keys along the lower
edge, see Figure 5.
LEDs
• ALARM LEDs
A ashing red LED adjacent to the
Sprinkler (IDC1) indicates an alarm.
• TROUBLE LEDs
A ashing yellow TROUBLE LED
for one of the IDCs, NACs, or RACs
indicates the presence of a circuit
break or ground within a system
point, or somewhere in the wiring
between the control panel and one
of its points.
• SUPERVISORY
A ashing yellow SUPERVISORY
LED indicates a problem with the
condition of the sprinkler system
controls or normal status (for exam-
ple, closed valve position for main
control valve, closed valve position
for system control valve, or high air
condition).
• SYSTEM TROUBLE
When a trouble occurs, the SYS-
TEM TROUBLE LED ashes until
accepted. When accepted, it
changes from ashing to steady.
• AC POWER
When lit steady, the green AC
POWER LED indicates the elec-
tronic control is receiving AC power
that is within the specied range.
If the LED is not lit and the panel is
still functioning, electronic control is
using battery power to operate. The
cause for loss of AC Power should
be determined and corrected. The
system is in a normal standby con-
dition when only the Green AC
POWER LED is ON.
CPVC Pipe and Fittings
Corrosion-resistant or internally gal-
vanized pipe must be utilized with the
sprinklers described in this data sheet.
TYCO BLAZEMASTER CPVC Pipe and
Fittings have been specically listed
for use in dry systems. Users must be
familiar with and follow listing parame-
ters, such as, maximum 15 psi (1,0 bar)
air pressure when utilizing CPVC prod-
ucts in a dry-type system.
To facilitate draining, piping in areas
subject to freezing shall be pitched in
accordance with NFPA 13D for dry pipe
systems.
The TYCO CPVC Sprinkler Head
Adapter Tee (P/N 80259) is to be
used with the dry-type residential
pendent sprinklers in dry pipe system
installations.
Refer to the TYCO technical manual
CPVC Fire Sprinkler Products Installa-
tion Instructions & Technical Handbook
(IH-1900).
Water Delivery
For dry pipe systems, the require-
ments for Dry System Water Delivery
per Section 8.3.4.3 of the 2010 edition
of NFPA 13D applies. Water deliv-
ery to the most remote single sprin-
kler for a residential hazard shall not
exceed 15 seconds. The use of the
TYCO SprinkFDT Fluid Delivery cal-
culation program is recommended to
assure a properly operating system can
be achieved prior to constructing the
actual installation.
Figures 1 and 2 provide a sample sprin-
kler layout and water delivery times that
can be expected for a dry pipe sprin-
kler system.
As an alternative to using a Listed
water delivery calculation program and
method as referenced in NFPA 13D, an
inspector’s test connection providing a
ow equivalent to the smallest orice
sprinkler may be utilized, wherein the
test orice is located on the end of
the pipe supplying the most remote
sprinkler.
NOTICE
In no case shall the time of water deliv-
ery exceed 15 seconds for the most
remote operating sprinkler.
Hydraulic Design (NFPA 13D)
The minimum required sprinkler ow
rates for systems designed to NFPA
13D (dry systems) are given in Tables A
to F as a function of temperature rating
and the maximum allowable coverage
areas. The sprinkler ow rate is the
minimum required discharge from each
of the total number of design sprinklers
(the two most hydraulically demanding
sprinklers) as specied in NFPA 13D.

Operation
The system is automatically main-
tained at a normal system air pressure
of 10 to 14 psi (0,7 to 1,0 bar) via the Air
Compressor. In the standby condition,
water is prevented from entering the
system piping until the Solenoid Valve
in the Manifold Assembly is opened in
response to the electronic control.
Operation sequence:
•
The normal standby condition is AC
green light ON.
•
Closure of Main Control Valve,
closure of System Control Valve, or
a high system pressure condition
results in a supervisory condition
(SPM1).
During a Supervisory Condition, the
Yellow SUPERVISORY LED ashes
and the tone-alert sounds steady.
After accepting, the tone-alert
silences and the Yellow SUPERVI-
SORY LED stays on until the condi-
tion clears.
•
Opening of a sprinkler results in
a low air condition of less than
nominally 8 psi (0,6 bar) resulting
in an alarm condition on IDC1,
opening of the Solenoid Valve
(RAC1), and operation of alarm noti -
cation devices (NAC1).
During an Alarm Condition, the
Red ALARM LED, corresponding to
Zone or SPM in alarm, ashes and
the tone-alert pulses. After accept-
ing, the tone-alert silences and the
Red ALARM LED stays on until the
alarm condition clears.
During a Trouble Condition, the yel-
low Trouble LED, corresponding
to the zone or SPM with a trouble
condition, ashes and the tone-
alert sounds steady. After accept-
ing, the tone-alert silences and the
Red ALARM LED stays on until the
alarm condition clears.
In Case of
Supervisory/
Trouble
Condition
Step 1. Verify that a re condition does
not exist.
Step 2. Close the Main Control Valve
to prevent inadvertent water ow into
the system.
Step 3. Acknowledge the supervisory/
trouble notification by momentarily
pressing the ACCEPT SIGNAL key.
Doing so silences the tone-alert.
Step 4. Determine and correct the
cause of the supervisory/trouble noti-
cation. Examples of causes can be
the following:
• Loss of primary 120 VAC power
• Low battery condition
• High air pressure
• Closure of the System or Main Con-
trol Valve
Step 5. Reset the system as soon as
possible.
In Case of
Alarm
Condition
Step 1. Verify that a re condition
exists and take appropriate action (that
is, evacuate the building and call re
department).
Step 2. After the re is extinguished,
reset the system.
If a re condition does not exist and
prior to resetting the system, silence
alarms as follows:
• First, momentarily press the ACCEPT
SIGNAL key a sufcient number of
times to stop the tone-alert.
• Second, momentarily press the SIG-
NAL SILENCE key.

NOTICE
Do not attempt to reprogram the Model
RCP-1 Panel. If assistance is required,
contact Technical Services at Johnson
Controls.
Remove resistors only when instructed
to do so. Failure to do so may lead
to improper conditions or failure of
the Model RCP-1 Panel to function
properly.
The cover is electrically bonded to the
enclosure ground terminal by means of
an 18 AWG conductor. Do not remove
the electrical bond.
Do not place any wiring in contact
with CPVC pipe and fittings. Plasti-
cizers, such as those found in flexible
wire insulation, can damage the pipe
and fittings through contact resulting
in damage/failure to the system.
Care and
Maintenance
The following inspection/test pro-
cedure for the Model RCP-1
Residential Control Panel must be per-
formed as indicated, in addition to any
specic requirements of the NFPA.
Any impairment must be immediately
corrected.
Before closing a re protection system
control valve for inspection or main-
tenance work on the re protection
system that it controls, obtain per-
mission to shut down the effected re
protection system from the proper
authorities and notify all personnel who
may be affected by this action.
The following inspection/test proce-
dures will result in operation of the
associated alarms. Notify the proper
authorities and advise those respon-
sible for monitoring proprietary and/or
central station alarms.
After placing a re protection system
in service, notify the proper authorities
and advise those responsible for moni-
toring proprietary and/or central station
alarms.
TYCO Sprinklers and CPVC Pipe and
Fittings are to be inspected and main-
tained in accordance with their appli-
cable data sheets.
Owners are responsible for the inspec-
tion, testing, and maintenance of their
re protection system and devices in
compliance with this document, as well
as with the applicable standards of the
NATIONAL FIRE PROTECTION ASSO-
CIATION, such as NFPA 25, in addition

Model RCP-1 Panel
Inspection/Test Procedure
The Model RCP-1 Panel can be
inspected and tested without having to
ow water into the system piping. The
inspection and testing, in accordance
with the requirements of NFPA 25, must
be performed annually.
General System Inspection/Test
Step 1. Verify the Air Pressure Gauge
indicates a system air pressure of 10
to 14 psi.
Step 2. Verify the Operator Interface
Panel of the Electronic Control only
indicates a green light for AC Power.
Step 3. Open and then close the Flow
Test Valve. The Water Supply Gauge
should drop to a previously noted
residual pressure and then return to
the normal static pressure.
Step 4. Perform a lamp test by press-
ing and holding the ACCEPT SIGNAL
key for a duration of ve seconds. Verify
that all system LEDs are functioning.
System Trip Test
Step 1. Close the System Control Valve
and accept the supervisory alarm at
the Electronic Control by pressing the
ACCEPT SIGNAL key.
Step 2. Partially open the Drain Valve to
relieve air pressure. When the system
trips (releases), completely open the
Drain Valve.
• Note that the Electronic Control IDC1
indicates alarm when the air pressure
gauge indicates nominally 8 psi.
• Note that the Electronic Control indi-
cates released.
• Note that water is discharging from
the drain line.
Step 3. Reset the Model RCP-1 Panel
following the appropriate resetting
instructions.
