1.1 Introduction

This specification is to apply to the control valves to be employed to control the

activation of fire protection to individual areas. They shall be electronically activated,

must have a manual override and may be of deluge or pressure controlling

configuration.

The fire system is pressurized up to the control valves so that the valves may rely on

hydraulic pressure in the lines to open and close and will normally remain closed

against pressure for long periods.

There are two liquids to be considered for the specification of the control valves. The

control valves will either operate exposed to only pumped borehole water or to

borehole water and foam premix at 3 or 6 percent mixture rate. The actual mixture rate

may be up to 8 percent.

The valves shall be suitable for fire duty and shall be installed in valve bunkers which

will be open on one side but will have a roof over the valves.









1.3.1 Equipment:

1) The valves shall be of the Inbal make or similar.



3) Control valves shall:

Have FM, UL or LPC approval for use in fire systems. Valves with alternative

approval may be submitted for consideration.

Be of ‘non-clack’ type.

Have “no moving mechanical parts”.


Revision No. A


Be axially symmetrical

Be suitable for mounting in the vertical position with a flow direction up

through the valve.

override at the valve.

a. The valves shall be energized to open

b. The manual override shall be able to activate the valve in the event of a

fail closed scenario.

Be remotely, electrically resettable.

Shall fail closed.

Shall be rated for outdoor use and shall not be adversely effected by rainfall

or exposure to sunlight. Where acceptable exceptions such as cosmetic

of closure

4) Control Valves are to operate on an on/off principle but shall be capable of

modulating the downstream pressure. The operation shall facilitate the

maintenance of the pressure downstream of the valve at a set value whenever the

upstream pressure is greater than that set pressure. The set pressure shall be

adjustable and is to be set during commissioning.

a. There shall be provision to lock out the pressure modulation setting to

prevent erroneous adjustment.




6) Control valves shall have winter-proof coverings to ensure operation even at the

minimum temperatures listed in the data sheet.

1.3.2 Supply:

1) The supplier shall provide installation instructions detailing the labor, equipment

1 TECHNICAL SPECIFICATION – FOAM DOSING PUMP

1.1 Introduction

This specification is to apply to the foam concentrate dosing system to be employed to

inject a proportional flow of foam concentrate into the water stream of the foam

application systems of a fire protection system when the system is in operation.

The foam dosing system is to induce foam concentrate into the water stream to certain

equipment at a nominal rate of 3% so that the resultant mixture is 3% concentrate and

97% water.

The system shall be suitable for fire duty and shall be installed in a pumphouse and will

draw foam concentrate from dedicated foam concentrate storage tanks within the

pumphouse.

The layout allows for the dosing pump to be isolated from the supply and discharge

lines for maintenance.

The water / premix discharge system shall be permanently pressurized by a jockey

pump, through the dosing system and up to the control valves. This shall pressurize

the downstream side of the dosing system and there shall be sufficient provision in the

specified dosing system to prevent any backflow of water into the foam concentrate

lines.









requirements:

1) The equipment shall be FM approved to class 5135.

2) The foam dosing system shall be suitable for accurately dosing the specified foam

concentrate into a pressurized water flow at 3%. The dosing range and accuracy

must comply with the requirements of NFPA.


Revision No. A


3) The dosing system must be capable of dosing at a rate of 6% as an option; if the

system doesn’t offer this option as standard it must be expandable to offer this

switchable option. The system should ideally be FM approved for 6% however

systems that have FM approval for 3% but not 6% may be considered. (The

current design doesn’t require 6% dosing however the client has specified this

requirement because of the potential future need for 6% foam mixture)

4) The foam dosing system must not require outside fuel or power and may be driven

through a water turbine system driven by the water flow.

5) The dosing system must operate to automatically induce the required rate of foam

concentrate over a range of flow rates from less than 10% to 100% of the nominal

flow rate.

6) The equipment must have the provision to either inject the concentrate or return

this to the storage tank.

7) The equipment must be fitted with a flow meter to determine the flow rate of

concentrate through the return line and should be configurable to operate at the

correct back pressure in order to accurately determine the dosing rate. This may

require two pressure relief valves, one as a safety for normal operation and the

other to be set at a lower pressure to simulate the operating back pressure when

the concentrate return system is in operation.

8) The equipment should have the provision to measure the water flow rate through

the water motor.

9) The equipment is to be securely mounted on a base frame which will allow

installation directly to a concrete plinth.

10) The equipment shall have provision for lifting and handling with a crawl beam.




13) The supplier shall provide assurance of availability of flanges and couplings

required to mate to all coupling points.

The supplier shall provide pricing for all required flanges or couplings.

The supplier shall, upon the request of the Purchaser, at any point prior to the

commissioning of the installation, supply (at a fair price) any couplings

required by the Purchaser to complete the installation.

Flanges shall be available in both 150 and 300 class.

ANSI B16.5 flanges are preferred.

14) Pumps shall be fitted with a name plate depicting the details of the pump, codes of

manufacture and approvals.



b. Performance data including:

i. Dosing rate curve across operating range

ii. Hydraulic loss information (Either equation and parameters, chart,

17) The equipment shall comply with the requirements of the OSH Act.


As per manufacturers specification and suitable for the installation. All piping and

pipework ancillary equipment should be stainless steel.




1) All equipment shall be aligned in the factory/workshop before delivery to site.

2) Factory testing shall be conducted with the Employer. Employers travel costs and

arrangements will be for the employers account.





6) The tenderer shall complete formal pre-commissioning, cold-commissioning and

hot-commissioning tests of the installation. These tests shall be comprehensive

and fully confirm the quality of the installation and the operation of the system. The

project manager must sign off the document after each stage and may also wish to

observe the commissioning. The tenderer may not commence the second or third

stage of commissioning without the previous stage having been signed off by the

project manager or alternative authorization from the project manager.
