SAFETY INFORMATION

National Foam

Red Alert Fire Emergency Service

National Foams Red Alert Emergency Service is a system set up to respond to an emergencysituation requiring foam, equipment or service and is available 24 hours a day, 365 days a year.

controller to the diaphragm valve.

NFdiaphragm valves, as previously mentioned, are

available in two versions. One version does not havemanual override capability. This version does not allow

manual regulation of foam concentrate inlet presssure in

the event of a diaphragm valve failure. The other version

does have manual override capability, which allows

manual regulation of the foam concentrate inlet pressure.

Pressure is adjusted by the operator by manually opening

the diaphragm valve (thru use of the Manual Override

Knob) and regulating the foam concentrate supply valve

(Valve "V") while watching the duplex gauge for system

balance. The duplex gauge monitors balancing of foam

concentrate and water pressures on a single gauge. Foam

concentrate pressure is indicated by the red pointer andwater pressure is indicated by the black pointer. When

the red pointer is directly aligned with the black pointer,

both pointing in the same direction, the system is balanc-

ing. Diaphragm valves that do not have manual override

capability also do not have a duplex gauge to monitor

pressure balance.

A National Foam ILBP Module is just one compo-

nent of an In-Line Balanced Pressure Proportioning

System. This type of foam proportioning system consists

of one or more ILBP Modules, a foam concentrate pump,

a pressure sustaining valve and a foam concentratestorage tank. An ILBP System requires a fire water

supply system for the module(s).

The ILBP Module is a complete, self-contained unit,

assembled and tested at the factory. The unit is supplied

with no finish and is suitable for either horizontal or

vertical mounting.

The principle of operation of the ILBP Module is

based on the use of a modified venturi proportioner

called a ratio controller. With this type of proportioner,

water passes thru a jet (venturi) at the inlet of the ratio

controller, creating a reduced pressure area on the dis-

charge side of the jet. This reduction in pressure creates

a pressure differential across the foam concentrate ori-

fice and causes injection of foam concentrate into the

water stream at this reduced pressure area.

As the water flow thru the ratio controller increases, thepressure reduction on the discharge side of the jet in-

creases, thereby increasing the pressure differential across

the foam concentrate orifice. A proportionate increase in

foam concentrate injection will occur with an increase in

the water flow thru the ratio controller due to the in-

creased pressure differential. As both the water and foam

concentrate flow into the common reduced pressure area,

it is necessary only to maintain identical water and foam

concentrate pressures at the inlets of the ratio controller.

A diaphragm valve (pressure control valve) automati-

cally adjusts the foam concentrate inlet pressure tocorrespond to the water inlet pressure. Pressure sensing

lines lead from the foam concentrate line upstream of the

ratio controller and from the water inlet to the ratio

A National Foam ILBP Module consists of the following major components:

Ratio Controller

Diaphragm Valve - with foam concentrate and water sensing lines

Two Versions

1. With Manual Override and Duplex Gauge

2. Without Manual Override and Duplex Gauge

Foam Concentrate Supply Pressure Gauge

Foam Concentrate Supply Valve

The appropriate lengths of pipe and fittings to join these components into a single

package called an In-Line Balanced Pressure Proportioning Module.

2-2. INSTALLATION AND START-UP: ILBP MODULE

CAUTION:

For proper piping sizes contact NF Engineering Department.

WARNING:

In accordance with NFPA requirements for supervision of an Automated Foam Fire Protection System -

manually operated valve(s) in the foam solution line from the proportioner to the discharge device(s) must be

chained or locked in the open position or equipped with tamper alarm switch(es) which are monitored by a

supervisory panel alarm.

The major concern is the possibility that any manually operated valve(s) in the foam solution line to the

hazard(s) could inadvertently be left in the closed position during a fire condition, which would prevent the foam

solution from reaching the hazard(s) in the event of an automatic trip sequence.

A. Off Loading:

WARNING:

Be sure the module is properly secured and balanced

during any lifting or moving procedure. If the module

is not properly secured in the lifting device, damage to

the module or injury to personnel could result.

1. To avoid damage, the module should be left in its

shipping carton or crate until time of installation into

foam system.

2. Use a nylon lifting strap, secured around the ratio

controller body, to move or mount the module.

B. Installation:

NOTE: Refer to Operating Schematic Drawing Fig. 3-1, 3-2 or 3-3.

1. Mount the module on the water piping main and

connect the foam concentrate supply piping to

the module. ILBP modules can be mounted in

either a horizontal or vertical orientation.

2. All interconnecting piping to and from the ILBP

Module (that is - foam concentrate supply pip-

ing, watermain piping and foam solution piping)

must be self-supporting so as to eliminate anyload on the module itself.

3. To facilitate future service/removal of the ratio

controller, the installer should provide a spool

piece upstream of the ratio controller. See Chart

below for minimum spool piece lengths.

Ratio Controller Minimum Spool Length

3" .......................................... 8" (203)

4" ........................................ 10" (254)

6" ........................................ 12" (305)

8" ........................................ 14" (356)

4. Each proportioner module requires 5 diameters of

straight unobstructed upstream and downstream

watermain piping to obtain proper flow through theratio controller.

CAUTION:

The ILBP Module requires a stable, uniform

water flow at the inlet to the ratio controller to

insure proper proportion ing during all rated

flow conditions.

INSTALLATION

5/23/2018 ILBP-Module_1298-9940-8_RevB

13/32

5. Regarding onlyRCF style ILBP modules:

A check valve mustbe placed in the foam con-

centrate line directly upstream of each

proportioner module.

6. Regarding only ILBP Module(s) that have adiaphragm valve with manual override capabil-

ity: If the module is used with an Automatic

Zone Foam Concentrate Supply Valve, the

Manual Foam Concentrate Supply Valve "V" is

still required for manual override pressure regu-

lation. Refer to Operating Schematic Dwg. Fig.

3-1 or Fig. 3-3 for valve locations and normal

stand-by position.

7. Cycle all valves to insure freedom of movement

and that they open and close properly.

8. For NF recommended components - valves,

strainers, gauges and connections, and their lo-

cation in the system, refer to the Operating

Schematic Drawing Fig. 3-1, 3-2 or 3-3.

12/98

9. Check that the system is properly installed accord

to design with all necessary valves, correct p

sizes, discharge devices and discharge device lo

tions, and is installed in compliance with local cod

10. Hydrostatically test piping in accordance with pcedures outlined in the latest edition of the applica

section of NFPA.

11. Flush the foam concentrate piping before introd

ing foam concentrate into the foam system.

12. Follow the procedures outlined in Section 2-2.

Installation, Item Nos. 7 and 8. Refer to Syst

Flushing procedures outlined in Sect. 4-15.

13. Place all valves to their normal stand-by positSee Normal Stand-By Valve Position Chart on O

erating Schematic Dwg. Fig. 3-1, 3-2 or 3-3.

14. Perform the applicable testing after installation p

cedures as recommended by the latest edition

NFPA 11.

C. Operating Requirements:

1. Foam concentrate pressure to the ILBP Moduleinlet mustexceed water pressure inlet by at least

30 psi (2.0 Bar) unless otherwise approved by

NF Engineering Department.

2. ILBP Module maximum working pressure - 200

psi(13.7 Bar).

3. Regarding only ILBP Module(s) that have a

diaphragm valve with manual override capabil-

ity:

The Manual Override Handwheel on the

diaphragm valve must be in the normal stand-

by position for automatic balancing. To placthe normal stand-by position: rotate

manual override handle in the counter-clo

wise direction until fully open.

Check the appropriate sensing line valv

3-1. MINIMUM INLET PRESSURE REQUIREMENTS

Since it is not uncommon for water inlet pressures to be quite low in some system applications, it is

necessary to determine that the minimum proportioning system inlet pressure is adequate to allow

proper system operation. The curves in Fig. 3-1 indicate the minimum inlet pressure required relative

to the anticipated flow rate of the system. These curves apply to all proportioning systems which

utilize National Foam Model RCT, RCF or RCW ratio controllers.

Factory Mutual Research and Engineering is a non-profit independent research and testing organization. FM testsand approves a wide variety of equipment, materials and services related to fire safety.

Each year FM publishes an Approval Guide listing all approved equipment, materials and services. This guide givesdetailed information on the approved products, as well as the operational parameters of the approval. In the case offoam proportioning systems, the parameters are the minimum and maximum foam solution flows and the foamconcentrates for which the proportioner is approved.

The following foam concentrates, along with the particular In-Line Balanced Pressure (ILBP) Proportioning Systemcomponents and discharge device(s) listed under the foam concentrate, constitute an FM Approved foam system. Anapproved system must consist of a foam concentrate, ILBP Proportioning system and discharge device(s).
