INSTALLATION AND MAINTENANCE INSTRUCTIONS

IMPORTANT

Please Read Carefully and Save

This instruction manual contains important information on the installation

and operation of supervisory switches. Purchasers who install supervisory

switches for use by others must leave this manual or a copy of it with the

user. These instructions apply to System Sensor switches for post indicator

and butterfly type valves. Read all instructions carefully before beginning

installation.

CAUTION

Do NOT use this switch in explosive or potentially explosive atmospheres.

Do NOT leave unused wires exposed.

Before installing any supervisory switches in sprinkler systems, be thoroughly

familiar with:

NFPA 72: Installation, Maintenance and Use of Local Protective

Signalling Systems

NFPA 13: Installation of Sprinkler Systems, specifically Section 3.17

NFPA 25: Inspection, Testing and Maintenance of Sprinkler Systems, specifi-

GENERAL INSTALLATION CONSIDERATIONS

1. Model PIBV2 is designed for installation in a

⁄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

⁄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

⁄2˝ NPT mounting hole,

remove the plug and go to step 6. If the post indicator valve is NOT

equipped with a

⁄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.
