devices.

Stainless steel construction.

Reduced maintenance costs.

ü Enhanced operational safety.

The K-5  Galley Fire suppression system has been designed to meet the require-

ments of ISO 15371. Recent changes to SOLAS regulations mean new demands

have been placed on ship owners and operators to ensure the health and safety

afforded to the ship and crew is upgraded. To meet that requirement, development

has been undertaken to design a complimentary marine version of the highly

successful and well established Nobel K Series Wet Chemical Fire Suppression

system.

Nobel K -Systems are fully independent systems, they are electrically actuated and

use spot heat detectors to detect fire conditions. The detectors are placed directly

over the appliance being protected or in the extract air flow above that appliance.

The cooking appliances can be individually protected or multiple systems can be

configured to suit the demands of any Galley.

Nobel K- Systems can be operated manually using push button switches located

at strategic positions around the kitchen. On receiving the appropriate FIRE signal

the system control panel sounds audible and visual alarms and immediately

initiates shut down of the power supply to the appliance/s being protected. Simulta-

neously the control system deploys the suppressant liquid onto the fire.

The gas required to pressurise the storage cylinder is produced in a controlled

manner from a solid propellant gas generator. The cylinder and gas generator 

remain at zero pressure until an electrical signal is received from the system

control panel. On actuation the cylinder is pressurised to 10-12 bar.

The Wet Chemical Suppressant Liquid Nobel-K has been specially formulated

to suppress fires in cooking oils and grease and prevent re-ignition. Rapid fire

knockdown is achieved and the fuel is cooled to below its auto ignition temperature.

A chemical process known as "Saponification" then provides added post fire

security by forming a thick soapy vapour barrier between the surface of the fuel and

the atmosphere.

Low Maintenance and High Reliabil i ty.

Nobel  fire suppression systems contain no moving parts and remain at ZERO

pressure until a fire condition has been detected. Consequently there is no scope

for failure due to leaking propellant gas or from faulty gauges, valves or mechanical

linkages. Continuous monitoring of the alarm input and extinguishing output circuits

is undertaken automatically at the control panel and fault modes are indicated

accordingly.

System storage cylinder 

The cylinder assembly is manufactured in stainless steel and has a capacity of 5

litres. A bursting disc assembly effectively seals the cylinder and secures the

integrity of the liquid. As the system is actuated the increase in pressure in the tank

ruptures the burst disc and allows the liquid to enter the stainless steel distribution

pipework.

The nozzles have been specifically designed to give rapid knock

down of the flames and fast cooling of the burning oils and fats to

below auto-ignition temperature. Each nozzle is manufactured

from stainless steel and produces a full cone mist. Each nozzle is

protected from the ingress of oils and grease by a protective blow

off cap.

ApprovalsThe K-5 system has undergone independent assessment to ISO 15371:2000: All

designs and testing have been audited, assessed and approved.

Gas Generator technology.

Each system is pressurised using a solid propellant gas generator, producing gas

at a pre-determined pressure to achieve maximum

system performance. The gas generators are mainte-

nance free and are based upon well proven defence

technology. The generator connects to the control

system via an IP67 rated plug and lead assembly to

enable easy secure connection and disconnection,

allowing a replacement cylinder assembly to be quick-

ly refitted into the system after discharge.

F ire Detection Metho d

Point detection is employed in each case. The units are

placed strategically to enable fast detection of a fire and

subsequent actuation of the fire suppression system. Proven

high reliability and quality.Spot Detector 

The gas generator allows the system to remain at ZERO pressure until electrically

actuated enhancing operational efficiency and safety,

by removing the need to transport, store, handle and

maintain high pressure gas cylinders or cartridges. The

loss of pressure due to leakage of expellant gas is

effectively ruled out.

Suppression release control panels

There are two control panels available the NFS 3 is the more complex unit, it can

be configured to protect two areas and up to four suppression systems. Each of 

these areas having a remote manual release The SOLO control panel is designed

for simplicity operating a single detection zone and having a single actuation

output. The panel incorporates a manual release facility. Each panel constantly

monitors detection and actuation circuits for faults and has 24hr 

battery backup in case of mains power failure. Panels provide

signals to the main ships alarm if required and in every instance

should be interfaced to automatically shut down power to the

affected cooking appliance via inbuilt volt free contacts.

Every system requires an electrical control panel. The panelreceives a signal from the detection device and automatically actuates the dis-charge circuitry. A manual actuator call point to override automatic detection anddischarge the system is fitted to each system. The NFS 3 can have the manualrelease positioned remotely, The Solo panel has an integrated release.
