gENERAL INSTALLATION CONSIDERATIONS
1. Model PIBV2 is designed for installation in a
1 ⁄
2
˝ NPT tapped hole and
located so that the actuating lever of the switch engages the target or flag
of the valve . The switch actuating lever is spring loaded against the flag
or target of the valve and is released when the valve moves toward the
closed position from the fully open position. The switch is factory set to
indicate an alarm condition when the target and lever move in the direc-
tion toward the conduit entry hole when the valve closes, but can be
reversed if the installation demands (refer to Section 4).
2. Model PIBV2 is equipped with a removable 1 ⁄
2
˝ NPT pipe nipple which
is locked in place with one set screw. A hex wrench is provided for this
feature. The PIBV2 also includes an adjustable length actuating lever.
3. The cover is secured with two tamper resistant screws which require a
special key to remove. One key is included with each supervisory switch.
Replacement and additional keys are available (Part No. WFDW).
SECTION 1
INSTALLATION INSTRUCTIONS FOR POST INDICATOR VALVES
1. There are two types of post indicator valves – rising flag and falling flag.
In a rising flag installation, the PIBV2 mounts below the target assembly,
as shown in Figure 2A. Closing the valve raises the target assembly and
releases the actuating lever on the PIBV2. In a falling flag installation, the
PIBV2 mounts above the target assembly (Figure 2B). Closing the valve
lowers the target assembly and releases the actuating lever on the PIBV2.
The PIBV2 is set for falling flag installation. If a rising flag operation is
desired, it is necessary to reverse the action of the switch (See Section 4).

2. If the post indicator valve is predrilled with 1 ⁄
2
˝ NPT mounting hole,
remove the plug and go to step 6. If the post indicator valve is NOT
equipped with a
1 ⁄
2
˝ NPT mounting hole, it will be necessary to drill and
tap the hole.
3. Position the valve in the fully open position (“OPEN” should appear in
the window) and remove the head and target assembly. In doing so, en-
sure that the assembly can be reinstalled with its original adjustment.
