INSTALLATION, OPERATION, and MAINTENANCE GUIDE
NIBCO Wall Mount Indicator Posts
Series NIP-2AW
• NIBCO Series NIP-2AW Wall Mount Indicator Posts are designed and manufactured to:
• Operate non-rising stem (NRS) post indicator valves (PIV) located through building walls
• Operate multi-turn post indicator valves (PIV) with an operating range from 10 to 50 turns
• Visually indicate if the valve is in the OPEN or SHUT position
• Provide a means to lock the valve into a desired position
(usually OPEN)
NIBCO Indicator Posts are listed by Underwriters
Laboratories Inc. (UL), Underwriters Laboratories Inc. for use
in Canada (C-UL), and approved by Factory Mutual Research
Corp. (FM).
It is important to follow the instructions below to assure
proper installation and safe trouble-free operation. Failure
to follow these instructions may result in reduced product
performance and may cause loss of manufacturer’s warranty.
1. Application
1.1 NIBCO Indicator Posts are primarily used with multi-turn non-rising stem (NRS) post indicator valves (PIV) controlling water
supplies to sprinkler, deluge, water spray, foam, and standpipe systems used in fire protection service.
1.2 NIBCO Indicator Posts are designed for outdoor service and are coated with electrostatically applied fusion bonded epoxy
resin to resist corrosion.
1.3 NIBCO Indicator Post view targets are adjustable to accommodate valves of various sizes.
1.4 NIBCO Indicator Posts are shipped for use with “left-hand” (counter-clockwise) opening valves.
1.5 NIBCO Indicator Posts are designed to allow the attachment of a Control Valve Supervisory Switch for electronic monitoring
of the OPEN valve position. Simply follow the instructions provided with the Supervisory Switch for proper installation and
operation.
1.6 NIBCO Wall Indicator Posts are designed to attach directly to the exterior of the building wall; four ¾” holes on a 10½”
diameter bolt circle.
1.7 Indicator Posts should be inspected on a regular basis.

4.5 Position OPEN Target Plates (8) so they are in the full upward position for “left-hand” (counter-clockwise) opening valves.
Secure OPEN Target Plates (8) by tightening Screws (37a). See Fig. 6.
4.6 Determine the number of turns required to fully open the valve. See Table 1 for NIBCO valves. You should always confirm
actual turns required to open the valve by counting them.
4.7 Using Table 6, choose the closest “Number of Turns to Open Valve” and the corresponding “Distance Between Targets”
dimension “X”.
4.8 Measure and position both SHUT Target Plates (9) at dimension “X” from OPEN Target Plates (8). See Fig. 6.
4.9 Secure both SHUT Target Plates (9) by tightening Screws (37a) with an Allen wrench.

7. Operation
7.1 The post indicator valve (PIV) can be opened or shut by rotating Handwheel (15) in the desired direction. To open the valve,
turn in the counter-clockwise direction as indicated on Cap (2). To shut the valve, turn in the clockwise direction. See Fig. 2.
7.2 The Target Plates (8) (9) can be visually checked in the view windows to determine if PIV is open or shut.
7.3 After installation, the PIV should be cycled to the full shut position and both view windows should be visually inspected to
assure the SHUT target plates are centered. The PIV should then be cycled to the full open position and both view windows
should be visually inspected to assure the OPEN target plates are centered.
7.4 Valve position can be secured by placing a customer supplied chain through U-bolt (23), and Handwheel (15). A customer
supplied lock can be installed into the chain and U-bolt securing Handwheel, preventing valve operation.
7.5 NIBCO Indicator Posts have provisions to add a Security Wire thru the Cap T-bolts (3) and Operating Stem (5) to prevent valve
operation.
8. Maintenance
8.1 Lubrication should be added to oil hole located in top of Operating Stem (5) on an annual basis. Note: it is necessary to
remove Eyebolt (16), Washer (17), and Handwheel (15) to expose the oil hole.
8.2 Periodic visual inspection is recommended.
8.3 Exercising (cycling) of the valve to assure proper function is recommended.
9. Repair Parts
9.1 Some specialty components are available for replacement if needed. See Table 5.
9.2 Common fasteners such as nuts, bolts, and washers are available at your local hardware.
