Worldwide Contacts www.tyco-fire.com Model QRS Electronic Accelerator (Quick Opening Device) For Dry Pipe or Preaction Systems General Description The TYCO Model QRS Electronic Accelera tor 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 in. & in. (DN00/0) Model DPV- Dry Pipe Valves Central in. (DN80) Model AF or Central in. & in. (DN00/0) Model AF/AG Dry Pipe Valves Gem in. & in. (DN00/0) Model F0/F0 Dry Pipe Valves Star in. & in. (DN00/0) Models A or A- Dry Pipe Valves The control panel for the QRS may be used with one QRS switch for one system riser using the following automatic control valve (deluge valve) used in a double interlock electric/electric preaction system: TYCO -/ in. thru 8 in. (DN0 thru DN00) DV- Deluge Valve The Model QRS Electronic Accelera tor (Ref. Figure ) 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 sec ond. When the air pressure is deter mined to have a sustained drop ex ceeding a rate of 0. psi (0,00 bar) per second as verified by three con secutive samplings, the QRS signals the Releasing Panel (Model PFC 0-RC) via its Panel Input initiating zone circuit, which energizes the Sole noid Valve. IMPORTANT Refer to Technical Data Sheet TFP00 for warnings pertaining to regulatory and health information. In the case of a dry pipe valve, the energized Solenoid Valve introduces system air pressure to the intermediate chamber of the dry pipe valve. This pressure neutralizes the differential pressure holding the dry pipe valve closed and permits it to open. In the case of a double interlock electric/electric preaction system, the energized Solenoid Valve releases diaphragm pressure from the automatic control valve (deluge valve) to permit the automatic control valve (deluge valve) to open. The Model QRS Electronic Accelerator 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 features the following: Operation of a dry pipe or preaction valve within four seconds independent 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 del uge and preaction systems Battery back-up in the event of primary power failure NOTICE The Model QRS Electronic Accelerator described herein must be installed and maintained in compliance with this document, as well as with the applicable standards of the NATIONAL FIRE PRO- TECTION ASSOCIATION, in addition to the standards of any other authorities having jurisdiction. Failure to do so may impair the performance of this de vice. The owner is responsible for maintaining their fire protection system and devices in proper operating condition. Contact the installing contractor or sprinkler manufacturer with any questions. The QRS uses electronic components to monitor the system air pressure. Keep all radio transmitters or RF sources at least one foot from the QRS. Failure to do so could result in an unintended operation of the dry pipe or preaction system. For additional information please refer to the Potter Electric Signal Company Data Sheet # for the QRS Quick Release Switch and/or Manual #00 for the PFC-0RC Releasing Panel.

TFP00 Page of NOTICE Quick operation of the Electronic Ac celerator 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 Connection). 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 preaction system, water delivery is also based on the electric detection system operating before the first sprinkler activates.

(0,00 bar/s) High/Low Pressure Settings Refer to Table A. Environmental Specifications The QRS Quick Release Switch is for indoor use only (NEMA /IP0). Battery Back-Up Battery back-up for dry pipe systems is provided by two BT-0 ( AH) batteries or two (optional) BT-80 (8 AH) batteries. (See Ordering Procedure for details.) The two BT-0 batteries provide: 0 hours in standby with four QRS s; With four QRS s connected, with one in alarm and the solenoid activated continuously, the batteries will provide additional hours of standby; With three QRS s connected, with one in alarm and the solenoid activated continuously, the batteries will provide additional hours of standby; With two QRSs connected, with one in alarm and the solenoid activated continuously, the batteries will provide 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. A battery calculation form can be accessed on the Potter web site at http://www.pottersignal.com/fire/ batterytools/php Installation The TYCO Model QRS Electronic Accelera tor must be installed in accordance with this section: Step. The QRS Electronic Accelera tor Riser Components (P/N -- 00) must be installed per Figure or 8 as applicable; the DV- Double Interlock Preaction Trim with Electric/Electric Actuation and Model QRS Electronic Accelerator must be installed per Figure A or B; the solenoid valve must be installed with its flow direction arrow as indicated; and, pipe thread sealant is to be applied sparingly to male threads only. Step. 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 multiple dry pipe valve risers, it is recommended that a single panel only be used when the multiple risers are ad jacent to each other. Otherwise, difficulty may be encountered when performing the resetting procedure.) Step. The QRS Quick Release Switch, Solenoid Valve, and Releasing Panel must be wired per Figure or, as applicable. All electrical connections are to meet the requirements of NFPA. NOTICE Figure provides the wiring connections for dry pipe systems using the PFC-0RC Standard Program #. Figure provides the wiring connections for a double interlock elec tric/ electric preaction system using the PFC-0RC Standard Program #. In the case of Figure, the EOLR for the supervisory circuit is located in the last QRS Quick Release Switch. In the case of Figure, the EOLR for the supervisory zone is located at the QRS and the Orange and Yellow wires are not used. Any tamper switches for sys tem shut off valves required for double interlock preaction systems should be connected to Zone of the PFC-0 RC releasing panel which is pro grammed as a Tamper Zone. Refer to PFC-0RC Manual #00. All QRS wiring must be terminated (landed) while the PFC-0RC is deenergized. Failure to do so may result in unseen damage to the QRS, rendering it inoperable. To de-energize the PFC-0RC, disconnect the stand-by batteries, then disconnect the A/C input. Reverse this process to re-energize the panel. For additional PFC-0RC Releasing Panel information (e.g., power and battery connections, programming, basic operation, etc.) refer to the Potter Electric Signal Company Manual #00. Step. As a function of the nominal air pressure to be maintained in the sprin kler system, set the 0 position, high/low level, rotary switch setting of the QRS Quick Release Switch using the information provided in Table A on Page, as well as inside the cover of the QRS Quick Release Switch. Step. 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-0RC Releasing Panel must be programmed using Standard Program # or #, as ap plicable. Programming instructions are provided in Potter Electric Signal Company Manual #00.

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 Connection). The sprinkler system designer has to be aware 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.. The sensitivity criteria for the Model QRS Electronic Accelerator is a function of its pressure decay for trip rating of 0. psi (0,00bar) 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 first sprinkler operation. Conversely, a smaller system volume combined with a larger sprinkler K-factor or higher initial air pressure results in a faster air decay rate.. 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 detection system operating before a first sprinkler operation.. 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.. When multiple sprinkler operations are being considered as in the case of using a dry system water delivery design per the 00 edition of NFPA, Section...9, use the. K-factor and larger curve as referenced in Example. EXAMPLES. Assuming a system volume of 00 gallons (80 liters) and the use of sprinklers having a K-factor of., the minimum system air pressure must be 8. psi (, bar).. Assuming a system volume of 000 gallons (0 liters) and the use of sprinklers having a K-factor of 8.0, the minimum system air pressure must be.0 psi (, bar).. Assuming the use of a dry system water delivery design per the 00 edition of NFPA, Section..., where in the operation of two. K-factor sprinklers might be anticipated (and the effective K-factor is then.), the. K-factor and larger curve can be utilized. Consequently, assuming a system volume of 00 gallons (908 liters), the minimum system air pressure must be. psi (0,8 bar).

TFP00 Page of 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 multiple risers, whenever the Program Switch is set to the PROGRAM position (Steps and ), the QRS Electronic Accelerators are taken out of service for all connected system risers. Therefore, the proper authorities and all personnel 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. If desired and until the system is to be set for service, the internal audible buzzer may be silenced by momentarily pressing the Buzzer Silence button (Figure ). Step. Locate all of the system s low point drain valves to help facilitate resetting of the system. Step. Follow the resetting procedure for the Dry Pipe Valve using the instructions provided in the technical data sheet for the Dry Pipe Valve. When the procedure calls for the system piping to be pressurized with air, proceed with Step. Step. Momentarily press the System Reset button (Figure ) 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-ener gized and allowed to close to enable pressurization of the system piping, and a 0 minute countdown to repres surize the system will be displayed. NOTICE If within 0 minutes, the Program Switch is not returned to the RUN position during the upcoming Step, the Releasing Panel will automatically re vert 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 supervisory condition will occur. If more than 0 minutes is required, the counter can be restarted before the 0 minutes has elapsed. In order to reset the counter, the system must be pressurized 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 0 minute countdown will then be restarted. Step. When the system reaches an air pressure of approximately 0 psi and while the system is in process of reaching its intended pressure, blowdown 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 procedure that will assure complete draining of the system will be more easily ac complished with 0 psi air pressure in the system. Step. When the system reaches the intended pressure and the pressure is stabilized, return the Program Switch (Figure ) to the RUN position. Step. After waiting at least 0 seconds, open the Inspector s Test Connection, wait 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 Operating Interface of the Releasing Panel will indicate operation. This procedure will also allow any scale and debris to be cleared 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, once again, 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 discharges 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 discharge 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 within the Technical Data Sheet for the dry pipe valve to determine/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 monitoring 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 possible after an operation. Follow the Valve Setting Procedure instructions provided in the Technical Data Sheet TFP. When Step 0 calls for resetting the actuation system, momentarily press the System Reset button (Figure ), and assuming that the Zone Alarm and Zone Low Air Alarm clear, proceed with the remaining instructions provided in TFP. NOTE: After setting a fire protection system, notify the proper authorities and advise those responsible for monitoring proprietary and/or central station alarms. Care and Maintenance The following procedures and inspections 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 (e.g., NFPA ), 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 Inspection Service.

NOTICE The QRS uses electronic components to monitor the system air pressure. Keep all radio transmitters or RF sources at least one foot from the QRS. Failure to do so could result in an unintended operation of the dry pipe or preaction system. Before closing a fire protection system main control valve for inspection or maintenance work on the fire protection system that it controls, permission to shut down the affected fire protection system must be obtained from the proper authorities and all personnel who may be affected by this action must be notified. If an Accelerator is to be temporarily taken out of service, the proper authorities 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 performed quarterly. Step. When operation of the dry pipe/ preaction valve is not intended during the Accelerator trip test, close the system 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. For a dry pipe system, open 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 Accelerator has tripped. In addition, the Display on the Operating Interface of the Releasing Panel will indicate operation. For a double interlock electric/electric preaction system, first operate the detection system and then open the Inspector s Test Connection. Verify that the time to Accelerator trip is essentially the same as in previous tests. Release of the DV- diaphragm pressure 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. Reset the Model QRS Electronic 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-0RC Releasing Panel.
