FM-200 SYSTEM : HYGOOD


System Components This section describes the individual components that comprise a complete system. Some items are optional depending on the application, and are indicated as such.

FM-200 CONTAINER

go top


	The agent storage vessel consists of a container fitted with a valve and internal syphon tube, factory filled with FM-200 , and super-pressurised with dry nitrogen to 25 bar @ 21๐C(360 psi @ 70๐F ). Containers sharing the same manifold shall be equal in size and fill density. Containers are finished in red and are available in various sizes .A nameplate is adhered to the container displaying the agent weight, tare weight, gross weight, fill density and charge date.

FIXING BRACKETS

go top


	The brackets assembly consists of a nut and bolt, two bracket straps and one back channel. To securely hold the container in position during the system discharge, two bracket assemblies are required per container. The only exception is the 8 litre container which only requires one. Each strap is notched for insertion into the back channel allowing the container to be properly aligned. The bracket assembly is designed to be mounted to a rigid vertical surface with the container assembly resting fully on the floor.

VALVE ASSEMBLY

	The Macron Safety Systems designed and manufactured container valve is the result of extensive research and development and incorporates many unique safety features. The valve assembly is factory-fitted to the container and is supplied pre-assembled with a low pressure switch, pressure gauge and burst disc.

PRINCIPLE OF OPERATION

go top

The Macron safety systems FM-200 valve is a high-flow-rate device specially designed for fire protection use. Operation is by means of a pressure-differential piston. Container pressure is used within the valve to create a positive force on piston, sealing the valve closed. Operation of the valve occurs when the upper chamber is vented faster than the ‘make up device’ in the shuttle can replace the pressure. Thereby allowing the shuttle to be forced up, and free flow of FM-200 from the valve. Upper chamber pressure is released by the electrical, mechanical or pneumatic actuator.

The valve incorporates the follow features:

A pressure operated safety release device (burst disc).
Main outlet, fitted with safety shipping cap.
A connection for a pneumatic or mechanical actuator, fitted with safety cap.
A connection for an electrical solenoid.
A connection for the pneumatic pilot signal output used for multiple container operation.

MANUAL ACTUATOR

	The manual actuator is a simple ‘strike knob’ assembly which is fitted to the top of the valve assembly or solenoid actuator. Inadvertent operation is prevented by a pin which has to be removed before activation.

PNEUMATIC ACTUATOR

go top

The pneumatic actuator is an assembly similar to the manual actuator but without the strike knob. Pressure from a ‘ master’ container or other sources is used to actuate the valve, via small bore piping or, preferably, a flexible hose.

REMOVABLE ELECTRICAL ACTURTOR

go top

The removable electrical actuator is also similar to the manual actuator and locates to the top of the container valve. 24V dc is required for solenoid operation. Provision is made for the connection of a manual strike Knob to the top of the actuator assembly.

DISCHARGE NOZZLE

go top



	FM-200 is distributed within the protected area by the discharge nozzle with the sized to ensure the correct flow of agent for the risk. Nozzles are available with seven or eight ports to allow for 180๐ or 360๐ horizontal discharge patterns. Ports are drilled in 0.1 mm (0.004 in) increments to the specified system design. BSP nozzles are supplied as standard in Brass and Stainless Steel with NPT as optional.

FOAM CHAMBERS
