NOTE: It is not necessary to remove the ARV to perform a hydrostatic test. The ARV may be adjusted temporarily to a pressure above the test pressure. Verify that the ARV is returned to its normal setting after completing the hydrostatic test.

FLOW SWITCH WIRING

The flow switch includes two sets of switches. One set can be used to activate the central fire alarm system, while the other set can be used to activate a local alarm, if necessary. Refer to the schematic below for the wiring diagram.

CONTROL VALVE WIRING
The following wiring instructions apply to both the Victaulic Series 728 FireLock™ Ball Valve and Victaulic Series 705 FireLock™ Butterfly Valve.

1. The supervisory switch contains two single-pole, double-throw, prewired switches.
2. Switches are rated:
   • 10 amps @ 125 or 250 VAC/60 Hz
   • 0.50 amps @ 125 VDC
   • 0.25 amps @ 250 VDC
3. Switches supervise the control valve in the “fully opened” position. Switches will not supervise the valve in the “closed” position.
4. One switch contains two #18 insulated wires per terminal, which permit complete supervision of leads (refer to diagrams and notes below). The second switch contains one #18 insulated wire per terminal. This double circuit provides flexibility to operate two electrical devices at separate locations, such as an indicating light and an audible alarm, in the area that the control valve is installed.
5. A #14 insulated ground lead (green) is provided.
   • Switch #1 = S1 For connection to the supervisory circuit of a UL Listed alarm control panel.
   • Switch #2 = S2 Auxiliary switch that may be connected to auxiliary devices, per the authority having jurisdiction.

Only S1 (two leads per terminal) may be connected to the fire alarm control panel. Connection of alarm switch wiring shall be in accordance with NFPA 72, and the auxiliary switch per NFPA 70 (NEC).

ARV SETTING PROCEDURE

• The 310-psi/21.4-Bar ARV is factory set to fully relieve at approximately 175 psi/12 Bar.
• During hydrostatic testing required per NFPA 13 System Acceptance Testing, the ARV may be set to a higher pressure; however, it shall be reset to relieve at a pressure that is in accordance with requirements of the local authority having jurisdiction and NFPA 13.
• To reset the ARV, use an adjustable crescent wrench to turn the hex cap clockwise for a higher pressure setting or counter-clockwise for a lower pressure setting. Use the calibrated lines on the stem for an approximate relief pressure setting. One full turn of the hex cap will result in approximately 25 psi/1.7 Bar increase or decrease.
• DO NOT adjust the calibration screw inside the hex cap, as indicated in the drawing to the left.

NOTE: An ARV replacement kit is available for order. This kit includes the ARV, a hose, and two worm gear hose clamps.

TESTING

Refer to NFPA 25, FM Datasheets, or any applicable local requirements to perform testing. The authority having jurisdiction in the area may require these tests on a more frequent basis. Verify these requirements by contacting the authority having jurisdiction in the affected area. Before proceeding with any tests involving water flow, the following precautions shall be taken.
NOTE: It is not necessary to remove the ARV to perform a hydrostatic test. The ARV may be adjusted temporarily to a pressure above the test pressure. Verify that the ARV is returned to its normal setting after completing the hydrostatic test.

1. Check for alarm connections to a central station or fire department. If such connections are found, notify the authority having jurisdiction, remote station alarm monitors, and those in the affected area before proceeding with testing. NOTE: A main drain test may also operate local fire alarms, unless they are temporarily disabled.
2. Check the location where the test connection discharges to verify that all is clear and that there is no possibility of water flow causing property damage or personal injury.
3. Check the end of the test connection to verify that it is unobstructed. To achieve a satisfactory test, there shall be an unrestricted flow of water when the handle on the UTD is in the “DRAIN” (full drain) position.
4. Move the handle on the UTD to the “TEST” (flow through K-factor orifice) position. Verify that an alarm condition results within the timeframe specified by the local authority having jurisdiction.
5. Move the handle on the UTD to the “OFF” (normal operating) position. NOTE: The ARV is located on the upstream side of the UTD and will continue to vent excess system pressure with the handle on the UTD in the “OFF” (normal operating) position.

NFPA 13 Hydrostatic Testing Procedure Required for System Acceptance Testing

• NFPA 13 requires an initial hydrostatic test of the sprinkler system to ensure that everything is properly assembled and capable of holding system pressure.
• This initial hydrostatic test requires the system to be pressurized to either 200 psi/13.8 Bar or 50 psi/3.4 Bar over the maximum expected system pressure (whichever is greater).
• The system shall maintain this pressure, without a loss, for a period of 2 hours.
• During this procedure, the ARV can remain in the system as long as it is set to a pressure where it will not relieve during the test.
• For systems being tested at 225 psi/15.5 Bar or less, it is recommended that the ARV set pressure be adjusted to 250 psi/17.2 Bar or greater for the duration of the test.
• For systems being tested at pressures higher than 225 psi/15.5 Bar, it is recommended that the ARV set pressure be adjusted to a minimum of 25 psi/1.7 Bar over the required hydrostatic test pressure.
• For systems where the ARV cannot be set to a pressure that is 25 psi/1.7 Bar over the required hydrostatic test pressure, it is recommended to plug the ARV port during the initial hydrostatic test.
• After the hydrostatic test procedure is complete, the ARV shall be set in accordance with the “ARV Setting Procedure” section on page 5.
