INSTALLATION OF THE SERIES 247

The Series 247 FireLock Residential Zone Control Riser Module
includes the module body, a UL or ULC Listed and FM Approved
waterflow detector, a pressure gauge with shutoff valve (provision for
draining), and an alarm test module available with different orifice sizes
(K-factors). In addition, an optional pressure relief valve kit is available.
Refer to the “Installation of the Optional Pressure Relief Valve Kit”
section.

NOTE CONCERNING WATERFLOW DETECTOR INSTALLATION AND
MAINTENANCE INSTRUCTIONS VERSUS RISER MANIFOLDS, AS
STATED FROM THE WATERFLOW DETECTOR MANUFACTURER: “The

section ‘Installation Guidelines’ suggests mounting the detector at least
6 inches/152 mm from a fitting that changes the direction of water flow
and no less than 24 inches/610 mm from a valve or drain. This is a
general statement that is superseded when a riser manifold assembly
is listed or approved by agencies such as UL and/or FM. The agency
approval takes precedence because this configuration has been tested
and its operation validated.”

1. Install the Series 247 into the system using Victaulic couplings for
grooved-end pipe. Always refer to the instructions, supplied with
the coupling, for complete installation requirements.

2. For the NPT threaded drain outlet, follow standard piping practices
to make the threaded connection. NOTE: The nominal drain size is
1 inch/25 mm. The drawings, shown on page 2, provide examples
of alternative ways to make the threaded drain connection with
a street elbow to avoid interference with couplings on the water
supply side and sprinkler distribution side of the module body.

3. Apply thread sealant to the threads of the pressure gauge. Install
the pressure gauge into the module body, as shown in the drawing
above. Make sure the face of the gauge is visible.

4. Connect the water-flow detector to the alarm system in accordance
with the instructions supplied.

5. To install the optional pressure relief valve, follow the instructions
in the “Installation of the Optional Pressure Relief Valve Kit”
section.

6. Perform the system flow test, as outlined in the “System Flow
Test” section.

• The Series 247 can be installed in either the horizontal
(left-to-right or right-to-left flow) or vertical (up) position.
The flow direction arrow MUST point toward the
sprinkler distribution, as shown in the drawing above.

EXAMPLES OF ALTERNATIVE WAYS TO MAKE THE THREADED DRAIN CONNECTION

The following drawings provide examples of alternative ways to make the threaded drain connection to avoid interference with couplings on the water
supply side and sprinkler distribution side of the module body. NOTE: These graphics show the Series 247 installed with the optional pressure relief
valve kit.

When installing a street elbow directly into the drain, the street elbow must be threaded into the drain

before the Series 247 is installed into the system with grooved pipe and grooved pipe couplings.

If the Series 247 was installed in the system before the connection to the drain was made,

install a close nipple and a straight coupling before installing the street elbow.

SYSTEM FLOW TEST

WARNING

• DO NOT operate the “Test/Drain Valve” under pressure.
Make sure the “Shutoff Valve” is in the “Closed”
position before operating the “Test/Drain Valve.”

Failure to follow these instructions could result in serious
personal injury and property damage.

Notify the authority having jurisdiction, remote station alarm monitors,
and anyone in the affected area that the system flow test is being
conducted.

1. Before performing the system flow test, confirm that all valves are
in their normal operating positions (“Shutoff Valve” in “Closed”
position, “Test/Drain Valve” in “Drain” position, and pressure
gauge shutoff valve in “Open” position).

2. Turn the thumb screw on the handle of the “Test/Drain Valve”
counterclockwise. Place the handle of the “Test/Drain Valve” in the
“Test” position.

3. Place the “Shutoff Valve” in the “Open” position.

4. Verify that the water-flow detector is operating properly and that
the alarms have sounded.

5. When the system flow test is complete, place the “Shutoff” valve in
the “Closed” position.

6. Place the “Test/Drain Valve” back to the “Drain” position. Hand­tighten the thumb screw on the handle.

CAUTION

• There must be NO shutoff valves between the Series
247 with pressure relief valve and the building drain.

• The pressure relief valve MUST be unrestricted in order
to discharge to the drain.

Failure to follow these instructions could result in
improper operation.

The following instructions apply to a Series 247 with pressure relief
valve installed in either the horizontal (left-to-right or right-to-left
flow) or vertical (up) position. The pressure relief valve is rated to

175 psi/1206 kPa.

1. Make sure all instructions in the “Installation of the Series 247”
section have been followed.

2. Remove the plugs from the drain port and the pressure relief valve
port. Refer to the drawings above.

3. Apply thread sealant to the threads of the close nipple and
pressure relief valve.

4. Install the close nipple into the drain port, as shown above.

5. Install the pressure relief valve into the pressure relief valve port,
as shown above.

6. Connect the drain tubing from the drain port’s close nipple to the
pressure relief valve using the barbed fittings and hose clamps
provided.

7. Follow all steps in the “System Flow Test” section.
