General
Description
The TYCO Model QRS Electronic
Accelerator is a quick opening device
intended to reduce the operating time
of a dry pipe valve in a dry pipe system
or an automatic control valve (deluge
valve) in a double interlock electric/
electric preaction system.
The control panel for the QRS may be
used with up to four QRS switches for
one to four system risers using one of
the following dry pipe valves:
• TYCO 4 in. & 6 in. (DN100/150)
Model DPV-1 Dry Pipe Valves
• Central 3 in. (DN80) Model AF or
Central 4 in. & 6 in. (DN100/150)
Model AF/AG Dry Pipe Valves
• Gem 4 in. & 6 in. (DN100/150) Model
F302/F3021 Dry Pipe Valves
• Star 4 in. & 6 in. (DN100/150) Models
A or A-1 Dry Pipe Valves
The control panel for the QRS may
be used with one QRS switch for one
system riser using the following auto-
matic control valve (deluge valve) used
in a double interlock electric/electric
preaction system:
• TYCO 1-1/2 in. through 8 in. (DN40
through DN200) DV-5 A Deluge Valve
The Model QRS Electronic Accelerator
(see Figure 1) utilizes a unique system
air pressure monitoring device (UL and
C-UL Listed, as well as FM Approved,
Model QRS Extinguishing System
Attachment) that continuously samples
air pressure twice per second. When
the air pressure is determined to have
a sustained drop exceeding a rate of
0.1 psi (0,007 bar) per second as veri-
fied by three consecutive samplings,
the QRS signals the Releasing Panel
(Model PFC4410-RC) via its “Panel
Input” initiating zone circuit, which
energizes the Solenoid Valve.
In the case of a dry pipe valve, the
energized Solenoid Valve introduces
system air pressure to the interme-
diate chamber of the dry pipe valve.
This pressure neutralizes the differen-
tial pressure holding the dry pipe valve
closed and permits it to open.
In the case of a double interlock elec-
tric/electric preaction system, the
energized Solenoid Valve releases dia-
phragm pressure from the automatic
control valve (deluge valve) to permit
the automatic control valve (deluge
valve) to open.
The Model QRS Electronic Accelera-
tor automatically adjusts to both small
and slow changes in system pressure,
but trips when there is a steady drop
in pressure (as in the case of sprinkler
operation).
The QRS Electronic Accelerator fea-
tures the following:
• Operation of a dry pipe or preaction
valve within four seconds — inde-
pendent of various combinations of
system initial air pressures, system
volumes, or sprinkler K-factors
• One Releasing Panel can control
up to four dry pipe systems or one
double interlock preaction system
• Built-in low pressure and high
pressure alarm supervision
• Proven electric release technology
as used for electrically operated
deluge and preaction systems
• Battery back-up in the event of
primary power failure
NOTICE
The Model QRS Electronic Accel-
erator described herein must be
installed and maintained in compli-
ance with this document, as well as
with the applicable standards of the
NATIONAL FIRE PROTECTION ASSO-
CIATION (NFPA), in addition to the
standards of any other authorities
having jurisdiction. Failure to do so may
impair the performance of this device.
The owner is responsible for main-
taining their fire protection system
and devices in proper operating con-
dition. Contact the installing contrac-
tor or sprinkler manufacturer with any
questions.
The QRS uses electronic compo-
nents to monitor the system air pres-
sure. Keep all radio transmitters or RF
sources at least one foot from the QRS.
Failure to do so could result in an unin-
tended operation of the dry pipe or pre-
action system.

NOTICE
Quick operation of the Electronic
Accelerator does not ensure that the
fire protection system will meet the
water delivery time requirement of the
authority having jurisdiction (following
opening of the Inspector’s Test Con-
nection). The sprinkler system designer
must be knowledgeable that water
delivery time is primarily determined
by the configuration and volume of the
piping network, system air pressure at
time of Accelerator trip, number and
orifice size of open sprinklers, and
water supply characteristics.
In the case of a double interlock pre-
action system, water delivery is also
based on the electric detection system
operating before the first sprinkler
activates.

Battery Back-Up
Battery back-up for dry pipe systems
is provided by two BT-120 (12 AH) bat-
teries or two (optional) BT-180 (18 AH)
batteries. See the Ordering Procedure
section for details.
The two BT-120 batteries provide:
• 40 hours in standby with four QRSs
• With four QRSs connected, with
one in alarm and the solenoid
activated continuously, the batteries
will provide 12 additional hours of
standby
• With three QRSs connected, with
one in alarm and the solenoid
activated continuously, the batteries
will provide 13 additional hours of
standby
• With two QRSs connected, with
one in alarm and the solenoid
activated continuously, the batteries
will provide 14 additional hours of
standby.
For double interlock preaction systems,
battery calculations must be performed
by the system designer to determine
adequacy of the two batteries to meet
the requirements of the authority having
jurisdiction.

Installation
The TYCO Model QRS Electronic
Accelerator must be installed in accor-
dance with this section.
Step 1. The QRS Electronic Accelerator
Riser Components (P/N 52-312-2001)
must be installed per Figure 2 or 8 as
applicable. The DV-5ADouble Interlock
Preaction Trim with Electric/Electric
Actuation and Model QRS Electronic
Accelerator must be installed per
Figure 3A or 3B. The solenoid valve
must be installed with its flow direc-
tion arrow as indicated. Apply the
pipe thread sealant sparingly to male
threads only.
Step 2. The Releasing Panel is to be
located in a dry and protected area;
however, it should be located in close
proximity to the valve riser(s). In the
case of one panel being used for mul-
tiple dry pipe valve risers, it is recom-
mended that a single panel only be
used when the multiple risers are adja-
cent to each other. Otherwise, difficulty
may be encountered when performing
the resetting procedure.
Step 3. The QRS Quick Release
Switch, Solenoid Valve, and Releas-
ing Panel must be wired per Figure 5
or 6, as applicable. All electrical con-
nections are to meet the requirements
of NFPA 72.
NOTICE
Figure 5 provides the wiring connec-
tions for dry pipe systems using the
PFC-4410RC Standard Program #14.
Figure 6 provides the wiring connec-
tions for a double interlock electric/
electric preaction system using the
PFC-4410RC Standard Program #13.
In the case of Figure 5, the EOLR for
the supervisory circuit is located in
the last QRS Quick Release Switch. In
the case of Figure 6, the EOLR for the
supervisory zone is located at the QRS
and the orange and yellow wires are not
used. Any tamper switches for system
shut off valves required for double
interlock preaction systems should
be connected to Zone 3 of the PFC-
4410RC releasing panel which is pro-
grammed as a Tamper Zone. Refer to
PFC-4410RC Manual #5403550.
All QRS wiring must be terminated
(landed) while the PFC-4410RC is de-
energized. Failure to do so may result in
unseen damage to the QRS, rendering
it inoperable.
To de-energize the PFC-4410RC, dis-
connect the stand-by batteries, then
disconnect the A/C input. Reverse this
process to re-energize the panel.
For additional PFC-4410RC Releasing
Panel information (for example, power
and battery connections, program-
ming, and basic operation) refer to the
Potter Electric Signal Company Manual
#5403550.
Step 4. As a function of the nominal air
pressure to be maintained in the sprin-
kler system, set the 10 position, high/
low level, rotary switch setting of the
QRS Quick Release Switch using the
information provided in Table A as well
as inside the cover of the QRS Quick
Release Switch.
Step 5. To complete the installation, the
cover of the QRS Quick Release Switch
must be securely fastened to the base
to ensure metal-to-metal contact, and
the PFC-4410RC Releasing Panel
must be programmed using Standard
Program #13 or #14, as applicable. Pro-
gramming instructions are provided in
Potter Electric Signal Company Manual
#5403550.

Notes:
1. Quick operation of the Electronic Accelerator does not ensure that the re protection system will meet the water
delivery time requirement of the authority having jurisdiction (following opening of the Inspector’s Test Connection).
The sprinkler system designer has to be aware that water delivery time is primarily determined by the conguration
and volume of the piping network, system air pressure at time of Accelerator trip, number and orice size of open
sprinklers, and water supply characteristics.
2. The sensitivity criteria for the Model QRS Electronic Accelerator is a function of its pressure decay for trip rating of
0.1 psi (0,007bar) per second, as well as the system volume, the K-factor of the sprinklers being utilized, and the
minimum initial air pressure. The larger the system volume combined with smaller sprinkler K-factor or lower initial
air pressure results in a slower air decay rate upon the rst sprinkler operation. Conversely, a smaller system vol-
ume combined with a larger sprinkler K-factor or higher initial air pressure results in a faster air decay rate.
3. When the sprinkler system has been designed with in the criteria provided by Graph A, operation of the Model QRS
Electronic Accelerator and subsequent operation of the associated dry pipe or preaction valve can be expected
within four seconds. In the case of the double interlock preaction system, operation is based on the electric detec-
tion system operating before a rst sprinkler operation.
4. The minimum system air pressure must be the greater of that required for the dry pipe / preaction valve as a
function of the maximum expected water supply pressure or per Graph A when using the Model QRS Electronic
Accelerator.
5. When multiple sprinkler operations are being considered as in the case of using a dry system water delivery design
per the 2002 edition of NFPA 13, Section 11.2.3.9, use the “11.2 K-factor and larger” curve as referenced in Exam-
ple 3.
Examples:
1. Assuming a system volume of 1500 gal (5680 L) and the use of sprinklers having a K-factor of 5.6, the minimum
system air pressure must be 18.5 psi (1,3 bar).
2. Assuming a system volume of 2000 gal (7570 L) and the use of sprinklers having a K-factor of 8.0, the minimum
system air pressure must be 16.0 psi (1,1 bar).
3. Assuming the use of a dry system water delivery design per the 2007 edition of NFPA 13, Section 7.2.3.6, where in
the operation of two 5.6 K-factor sprinklers might be anticipated (and the effective K-factor is then 11.2), the “11.2
K-factor and larger” curve can be utilized. Consequently, assuming a system volume of 2400 gal (9084 L), the mini-
mum system air pressure must be 11.5 psi (0,8 bar).

Setting
Procedure
(Dry Pipe
System)
The Dry Pipe System and the TYCO
Model QRS Electronic Accelerator
must be reset and restored to service
as soon as possible after an operation.
NOTICE
The system must be completely drained
before proceeding.
In the case of one panel serving mul-
tiple risers, whenever the Program
Switch is set to the PROGRAM posi-
tion (Steps 4 and 7), the QRS Electronic
Accelerators are taken out of service
for all connected system risers. There-
fore, the proper authorities and all per-
sonnel who may be affected must be
notified. In the event of a fire and where
a QRS Electronic Accelerator has been
taken out of service, an increased time
in water delivery can be expected.
Step 1. Until the system is to be set
for service, the internal audible buzzer
may be silenced by momentarily press-
ing the BUZZER SILENCE button
(Figure 7).
Step 2. Locate all of the system’s low
point drain valves to help facilitate
resetting the system.
Step 3. Follow the resetting procedure
for the Dry Pipe Valve using the instruc-
tions provided in the Technical Data
Sheet for the Dry Pipe Valve. When
prompted to pressurize the system
piping with air, proceed with Step 4.
Step 4. Momentarily press the SYSTEM
RESET button (Figure 7) and then set
the Program Switch to the PROGRAM
position. The display will read “OK to
charge system.” Begin applying air
pressure to the system. At this point
the solenoid valve will be de-energized
and allowed to close to enable pressur-
ization of the system piping, and a 30
minute countdown to repressurize the
system will be displayed.
NOTICE
If within 30 minutes, the Program
Switch is not returned to the RUN
position during the upcoming Step 6,
the Releasing Panel will automatically
revert to a normal condition. If at least 8
psi has not been reached, the solenoid
valve will be energized and open. If at
least the low air pressure threshold of
Table A has not been reached, a super-
visory condition will occur.
If more than 30 minutes is required, the
counter can be restarted before the 30
minutes has elapsed. In order to reset
the counter, the system must be pres-
surized to at least 8 psi, at which time
the Program Switch can be set to the
RUN position and then quickly back to
the PROGRAM position. A 30 minute
countdown will then be restarted.
Step 5. When the system reaches an
air pressure of approximately 10 psi,
and while the system is in process of
reaching its intended pressure, “blow-
down” each drain valve one at a time,
including the low body drain or priming
level valve, at the dry pipe valve and
the Inspector’s Test Connection by
opening each drain valve until water
ceases to drain and then closing the
drain valve. The blow-down proce-
dure that will assure complete drain-
ing of the system will be more easily
accomplished with 10 psi air pressure
in the system.
Step 6. When the system reaches the
intended pressure and the pressure is
stabilized, return the Program Switch
(Figure 7) to the RUN position.
Step 7. After waiting at least 60
seconds, open the Inspector’s Test
Connection, wait 5 seconds, and then
close the Inspector’s Test Connection.
Verify that the time to Accelerator trip
is essentially the same as in previous
tests. A momentary burst of air from a
dry pipe valve’s Automatic Drain Valve
indicates that the QRS has tripped. In
addition, the display on the Operat-
ing Interface of the Releasing Panel
will indicate operation. This procedure
clears any scale and debris from the
pipe and nipples that are connected to
the solenoid valve.
Momentarily press the SYSTEM RESET
button and then set the Program Switch
to the PROGRAM position. The display
will read “OK to charge system”. At
this point, the solenoid valve will be
de-energized and allowed to close to
enable pressurization of the system
piping.
Allow the system to automatically
return to its intended pressure via its
automatic air supply, and, after waiting
for the pressure to stabilize, return the
Program Switch to the RUN position.
Step 8. Partially open the Main Control
Valve. Slowly close the system’s Main
Drain Valve as soon as water dis-
charges from the drain connection.
Depress the plunger on the dry pipe
valve’s Automatic Drain Valve to make
sure that it is open and that no water
discharges. The absence of water dis-
charge from the Automatic Drain Valve
is an indication of a properly set water
seat within the dry pipe valve. If water
is discharging, refer to the Care and
Maintenance section of the Technical
Data Sheet for the dry pipe valve to
determine and correct the cause of the
leakage problem.
If there are no leaks, the system’s Main
Control Valve must be fully opened.
The system is now set for service.
NOTE: After setting a fire protection
system, notify the proper authorities
and advise those responsible for moni-
toring proprietary and/or central station
alarms.
Setting
Procedure
(Preaction
System)
The Double Interlock Electric/Electric
Preaction System and the Model QRS
Electronic Accelerator must be reset
and restored to service as soon as pos-
sible after an operation.
Follow the Valve Setting Procedure
instructions provided in the Technical
Data Sheet TFP1450. When prompted
to reset the actuation system, momen-
tarily press the SYSTEM RESET button
(Figure 7), and assuming that the Zone
1 Alarm and Zone 2 Low Air Alarm
are clear, proceed with the remaining
instructions provided in Technical Data
Sheet TFP1450.
NOTE: After setting a fire protec-
tion system, notify the proper authori-
ties and advise those responsible for
monitoring proprietary and/or central
station alarms.

Care and
Maintenance
The following procedures and inspec-
tions should be performed as indicated,
in addition to any specific requirements
of the NFPA, and any impairment must
be immediately corrected.
The owner is responsible for the
inspection, testing, and maintenance of
their fire protection system and devices
in compliance with this document, as
well as with the applicable standards
of the NATIONAL FIRE PROTECTION
ASSOCIATION, for example, NFPA
25, in addition to the standards of any
authority having jurisdiction. Contact
the installing contractor or product
manufacturer with any questions.
It is recommended that automatic
sprinkler systems be inspected, tested,
and maintained by a qualified Inspec-
tion Service.
The Model QRS Electronic Accelera-
tor must be maintained and serviced
in accordance with this section.
NOTICE
The QRS uses electronic compo-
nents to monitor the system air pres-
sure. Keep all radio transmitters or RF
sources at least one foot from the QRS.
Failure to do so could result in an unin-
tended operation of the dry pipe or pre-
action system.
Before closing a fire protection system
main control valve for inspection or
maintenance work on the fire protec-
tion system that it controls, permission
to shut down the affected fire protec-
tion system must be obtained from
the proper authorities and all person-
nel who may be affected by this action
must be notified.
If an Accelerator is to be temporarily
taken out of service, the proper author-
ities and all personnel who may be
affected must be notified.
Model QRS Electronic Accelerator
Testing Procedure
It is recommended that the following
Accelerator test procedure be per-
formed quarterly.
Step 1. When operation of the dry pipe/
preaction valve is not intended during
the Accelerator trip test, close the sys-
tem’s Main Control Valve and open the
system’s Main Drain Valve to relieve
the supply pressure to the dry pipe/
preaction valve. Otherwise, proceed
as follows.
Step 2. For a dry pipe system, open the
Inspector’s Test Connection. Verify that
the time to Accelerator trip is essen-
tially the same as in previous tests.
A momentary burst of air from a dry
pipe valve’s Automatic Drain Valve indi-
cates that the Accelerator has tripped.
In addition, the display on the Operat-
ing Interface of the Releasing Panel will
indicate operation.
For a double interlock electric/elec-
tric preaction system, first operate the
detection system and then open the
Inspector’s Test Connection. Verify that
the time to Accelerator trip is essen-
tially the same as in previous tests.
Release of the DV-5Adiaphragm pres-
sure though the open solenoid valve
indicates that the Accelerator has
tripped. In addition, the display on the
Operating Interface on the Releasing
Panel will indicate operation.
Step 3. Reset the Model QRS Elec-
tronic Accelerator in accordance with
the appropriate Setting Procedure
section.
Releasing Panel and Batteries
Inspect, test, and maintain per the
instructions provided for the Model
PFC-4410RC Releasing Panel.
