VIZOR Electronic Dry Pipe Accelerator (EDPA) Quick-Opening Device for Dry Pipe Systems
General Description
The TYCO VIZOR Electronic Dry Pipe Accelerator (EDPA) is a quick-opening device intended to reduce the operat­ing time of the dry pipe valves listed in Table A following operation of one or more automatic sprinklers.
Unlike traditional mechanically oper­ated quick-opening devices, the VIZOR Accelerator is a microprocessor-based, electronic, quick-opening device. The VIZOR Accelerator automatically adjusts to both small and slow changes in system air pressure, but trips when there is a steady drop in system air pressure upon sprinkler operation.
The VIZOR Accelerator features the following:
• Direct mounting to the riser
Installation consistent with the installation of mechanical devices
Easy test-and-reset function, as compared to mechanical accelerators
Operation of a dry pipe valve within four seconds — over a wide range of system volumes, system initial air pressures, and sprinkler K-factors
Built-in low-pressure and high-pres­sure alarm supervision
Electronically self-supervising technology, similar to that used in typical alarm panels for alarm and detection systems
Battery back-up in the event of primary power failure
The VIZOR Electronic Dry Pipe Acceler­ator utilizes a unique, patented system air pressure monitoring design that continuously samples the system air pressure.
IMPORTANT
When the VIZOR Accelerator detects a sustained drop in air pressure, the VIZOR Accelerator energizes its inter­nal solenoid valve.
The energized solenoid valve then opens to permit system air pressure into the intermediate chamber of the dry pipe valve.
The pressurized intermediate chamber neutralizes the differential pressure holding the dry pipe valve closed and permits the dry pipe valve to trip and flow water into the system piping.
NOTICE
The VIZOR Electronic Dry Pipe Acceler­ator described herein must be installed and maintained in compliance with this document and with the applicable stan­dards of the NATIONAL FIRE PROTEC­TION ASSOCIATION, in addition to the standards of any authorities having jurisdiction. Failure to do so may impair the performance of this device.
The owner is responsible for main­taining their fire protection system and devices in proper operating con­dition. Contact the installing contrac­tor or product manufacturer with any questions.
Technical Data
NOTICE
Quick operation of the TYCO VIZOR Electronic Dry Pipe 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 the time of accelerator trip, number and orifice size of open sprinklers, and water supply character­istics. It is essential for the designer to verify the impact of these site-specific factors on water delivery time.

lations or to replace mechanical type accelerators in existing systems.
The VIZOR Accelerator operates upon detection of a steady drop in air pres­sure of 0.1 psi per second (0,007 bar/s) or greater, or if the pressure drops to
5.5 psi (0,38 bar). The VIZOR Accelera-
tor typically responds to an open sprin­kler in approximately 2 seconds.
In order to minimize false trips and high/low air trouble conditions, the use of a tank mounted air compres­sor or plant air in conjunction with the TYCO AMD-1 Air Maintenance Device is strongly recommended, The com­pressor, or plant air, should be set to maintain a minimum of 10 psi greater than the required system air pressure.
Note: Although the VIZOR Accelera­tor is designed to respond to an open sprinkler in approximately 2 seconds, operation of the dry pipe valve is expected within 4 seconds. The dif­ference of 2 seconds is a conser va­tive estimation for the dry pipe valve to physically trip.
Upon detection of a drop in air pres­sure, the VIZOR Accelerator opens an internal solenoid valve allowing system air pressure into the intermedi­ate chamber of the dry pipe valve. The pressurized intermediate chamber neu­tralizes the differential pressure holding the dry pipe valve closed and permits the valve to open. The solenoid valve automatically closes after 30 seconds.
The VIZOR Accelerator contains two sets of normally open, dry contacts. The High/Low Supervisory Contacts close if the normal system air pressure in the system increases or decreases beyond a given point (refer to Table B). The ten-position rotary switch (refer to Figure 2) provides ten preset pressure settings. The factory setting is position #4 for a normal system air pressure of 30 psi.
The Trouble Dry Contacts close during any one of the following conditions:
Low-battery condition (up to a 1-minute delay is normal)
AC power loss (after a 60-minute delay)
SET/OFF switch in the OFF position
An internal buzzer sounds during any off-normal condition.
Installation
The TYCO VIZOR Electronic Dry Pipe Accelerator must be installed in accor­dance with this section.
NOTICE
When working on the VIZOR Accelera­tor or the dry pipe valve, S1 should be in the OFF position; otherwise, the dry valve can inadvertently trip.
Make all pipe fitting connections to the VIZOR Accelerator inlet and outlet ports by using the wrench flats on the

Notes
1.
Quick operation of the TYCO VIZOR Electronic Dry Pipe 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. It is essential for the designer to verify the impact of these site-specic factors on water delivery time.
2.
The sensitivity criteria for the VIZOR Accelerator is a function of its pressure decay for trip rating of 0.1 psi (0,007 bar) 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 volume 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 within the criteria provided by Graph A, operation of the VIZOR 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 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 VIZOR Accelerator.
5.
When considering multiple sprinkler operations as in the case of using a dry system water delivery design per NFPA 13, use the “11.2 K-factor and larger” curve as referenced in Example 3 below.
Examples
1.
For a system volume of 1500 gallons (5680 liters) 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.
For a system volume of 2000 gallons (7570 liters) 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.
With the use of a dry system water delivery design per NFPA 13, wherein 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, for a system volume of 2400 gallons (9084 liters), the minimum system air pressure must be 11.5 psi (0,8 bar).

VIZOR Accelerator. DO NOT tighten connections by grasping the VIZOR Accelerator housing. Failure to do so may result in damage to the compo­nents within the device.
Install all required conduits and make all connections with AC power off. The VIZOR Accelerator must be hard-wired to complete the installation.
During installation, the buzzer may sound. Silence the buzzer at any time by momentarily pushing S2 to the SILENCE position.
The VIZOR Accelerator must be installed according to applicable NFPA codes (for example, NFPA 13, 70, and 72) as well as all local instal­lation codes.
Step 1. Install the VIZOR Accelera­tor as shown in Figures 6 and 7. Apply pipe-thread sealant sparingly to male threads only.
Step 2. Following Figure 2 and Table B, set the Ten-Position Rotary Switch to the required setting using the provided screw driver.
Step 3. As shown in Figure 2, tape the 12V, 1.3 AH Batteries together. Connect the Harness wires (Leads in Figure
2) to the Batteries, slide the Battery Assembly into the Housing, and plug the Harness Connector into the VIZOR Accelerator circuit board.
For the optional 90-hour batteries, mount the Remote Battery Enclosure horizontally and within 10 feet of the VIZOR Accelerator. Splice the battery cable (Figure 5), connect the cable to the Batteries, then plug the Battery Assembly into the VIZOR Accelera­tor Harness. Lastly, plug the Harness Connector into the VIZOR Accelerator circuit board.
Step 4. Close and lock the cover.
Step 5. Push S1 to the OFF position.
Step 6. In order to minimize an inad-
vertent primary (A /C) power loss and to facilitate maintenance, it is recom­mended that a dedicated circuit be hard-wired to the VIZOR Accelerator. The following notifications occur:
The Green AC LED lights, the Amber Trouble / Supervisory LED lights, the Red Tripped LED lights, and the buzzer sounds.
Assuming the batteries are charged, the Amber Battery Trouble LED remains unlit.
Step 7. Optionally conduct trip tests of the VIZOR Accelerator and the dry pipe valve in accordance with the Care and Maintenance section.
Step 8. Optionally, and/or if required by local jurisdiction, hard-wire moni­toring circuits to the Trouble and High/ Low supervisory contacts using 14 to 18 AWG wire.
Step 9. Push S1 to the SET position.
Step 10. Verify proper operation of the
VIZOR Accelerator using the “No Flow Trip Test for Accelerator Only” proce­dure described in the Care and Main­tenance section.
Setting Procedure
As soon as possible after an opera­tion, reset and restore to service the Dry Pipe Valve (listed in Table A) and the TYCO VIZOR Electronic Dry Pipe Accelerator in accordance with the fol­lowing procedure.
NOTICE
Completely drain the system before proceeding.
After setting a fire protection system, notify the proper authorities and advise those responsible for monitoring pro­prietary and/or central station alarms.
Step 1. Push S1 to the OFF position.
Step 2. Silence the internal audible
alarm at any time by momentarily pushing S2 to the Silence position.
Step 3. Locate all of the system’s low point drain valves to help facilitate resetting of the system. Refer to the appropriate dry valve data sheet for valve resetting procedures.
Step 4. Clean the strainer by removing the clean-out plug and strainer basket.
Step 5. Follow the resetting procedure for the installed dry pipe valve. When the procedure calls for the system piping to be pressurized with air, start to pressurize the system and then proceed to Step 6.
Step 6. When the system reaches an air pressure of approximately 10 psi and while the system is in the process of reaching its intended pressure, “blow-down” each drain valve. Be sure to include the low body drains at the dry pipe valve and the Inspector’s Test Connection.
To “blow-down”, open each drain valve individually, and when water stops draining, close the drain valve. This blow-down procedure assures that complete draining of the system can be more easily accomplished.
Step 7. When the system reaches the normal intended air pressure, wait approximately 30 seconds to allow for stabilization of the air pressure within the piping. Momentarily push button S2 on the VIZOR to the RESET posi­tion to clear the red tripped LED, and then push button S1 the SET position.
Step 8. Open the Inspector’s Test Con­nection (ITC), verify that the VIZOR has tripped. A momentary burst of air from the dry pipe valve’s automatic drain valve indicates that the VIZOR Accel­erator has tripped. Verify that the time­to-trip for the accelerator is essentially the same as in previous tests.
This procedure also clears scale and debris from the pipe and fittings that are connected to the VIZOR Accelerator.
Step 9. Push S1 to the OFF position, allow the system to automatically return to its intended pressure via its auto­matic air supply. After waiting approxi­mately 30 seconds, momentarily push S2 to the RESET position, and then push S1 to the SET position.
Step 10. Partially open the Main Control Valve. Slowly close the system’s Main Drain Valve as soon as water dis­charges from the drain connection.
Step 11. Depress the plunger on the dry pipe valve’s automatic drain valve to verify 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, fully open the sys­tem’s Main Control Valve.
The system is now set for service.

Care and Maintenance
The TYCO VIZOR Electronic Dry Pipe Accelerator must be inspected and maintained in accordance with the NFPA. The following test procedures must be performed in addition to any specific requirements of the NFPA. Any impairment must be immediately corrected.
Before closing a fire protection system main control valve on the system that it controls, obtain permission from the proper authorities to shut down the affected fire protection system and notify all personnel who may be affected by this action.
In accordance with the requirements of NFPA 25 and 72, one of the trip tests described in this section must be per­formed quarterly. Battery tests also described here must be performed semi-annually and annually.
The VIZOR Accelerator uses electronic components to monitor the system air pressure. Keep all radio transmitters or RF sources at least one foot from the VIZOR Accelerator. Failure to do so could result in an unintended operation of the dry pipe system.
Notify the proper authorities and all personnel who may be affected before temporarily disabling the VIZOR Accel­erator or performing an alarm test.
The VIZOR Accelerator must be in a normal condition for 60 seconds before conducting a trip test. Failure to wait 60 seconds after air pressure has reached the normal level will result in a failed test.
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 25 and 72), in addition to the standards of any authority having jurisdiction. Contact the installing contractor or product manufacturer with any questions.
Automatic sprinkler systems are rec­ommended to be inspected, tested, and maintained by a qualified Inspec­tion Service.
Full Flow Trip Test: Valve and Accelerator
Step 1. Open the Inspector’s Test Con­nection. Verify that the VIZOR Accel­erator trip-time is essentially the same as in previously performed tests. Also, make sure that the following notifica­tions occur (Ref. Figure 1):
• Red Tripped LED lights
Amber Trouble/Supervisory LED ashes 4 times per second (fast)
• Buzzer sounds
• High/Low Contacts transfer
Step 2. Verify that the dry pipe valve tripped and that the time for water delivery to the Inspector’s Test Con­nection is essentially the same as in previous tests.
Step 3. After verification of water deliv­ery to the Inspector’s Test Connection, close the system’s Main Control Valve and reset the system.
Partial Flow Trip Test: Valve and Accelerator
Step 1. Close the system’s Main Control Valve and then open the sys­tem’s Main Drain Valve to relieve the supply pressure to the dry pipe valve.
Step 2. Partially open the system’s Main Control Valve at least to the point at which water can be heard flowing though the system’s Main Drain Valve, and then slowly close the system’s Main Drain Valve.
Step 3. Additional turns may be nec­essary to ensure latching of the appro­priate dry pipe valve; refer to the appropriate technical data sheet.
Step 4. Open the Inspector’s Test Con­nection. Verify that the time-to-trip for the VIZOR Accelerator is essentially the same as in previous tests. A momen­tary burst of air from the dry pipe valve’s automatic drain valve indicates that the VIZOR Accelerator has tripped. Also, verify that the following notifica­tions occur (Ref. Figure 1):
• Red Tripped LED lights
Amber Trouble/Supervisory LED ashes once per second (slow)
• Buzzer sounds
• High/Low Contacts transfer
Step 5. Verify that the dry pipe valve tripped and waterflow alarms operate.
Step 6. Immediately after verification of the dry pipe valve trip, close the sys­tem’s Main Control Valve and reset the system.
No Flow Trip Test: Accelerator Only
Step 1. Close the system’s Main Control Valve and then open the sys­tem’s Main Drain Valve to relieve the supply pressure to the dry pipe valve.
Step 2. Open the Inspector’s Test Con­nection. Verify that the time-to-trip for the VIZOR Accelerator is essentially the same as in previous tests. A momen­tary burst of air from the dry pipe valve’s automatic drain valve indicates that the VIZOR Accelerator has tripped. Also, make sure that the following noti­fications occur (Ref. Figure 1):
• Red Tripped LED lights
Amber Trouble/Supervisory LED ashes once per second (slow)
• Buzzer sounds
• High/Low Contacts transfer
Step 3. Reset the system.
Battery Tests
Perform the following tests to verify that the batteries are connected and working and to verify battery levels.
Battery Connections
Perform this test semi-annually.
1.
Open the Battery Housing and un­plug the Batteries from the VIZOR Accelerator circuit board.
2.
Verify that the VIZOR Accelera­tor registers battery trouble and sounds the internal audible alarm.
3. Press S2 to the Silence position.
4.
Plug the Batteries back into the VIZOR Accelerator circuit board and close the Housing.
5. Verify battery trouble clears.
Battery Levels
Perform a battery load test annually. An alarm-and-detection technician can perform this test.
