DESCRIPTIVE, OPERATION & MAINTENANCE MANUAL FOR FIRE DETECTION AND SUPPRESSION SYSTEM
Introduction

DMM/FDAS/001 REV:-01
DT. OF ISSUE:10.10.2015

1.1

General

This document describes the scope of operation, maintenance and service

that is necessary in order to maintain performance and reliability of the

SANROK “AUTOMATIC FIRE DETECTION CUM MANUAL HIGH

PRESSURE WATER MIST SUPPRESSION SYSTEM FOR PANTRY CAR &

GENERATOR CUM BRAKE VAN OF INDIAN RAILWAY COACHES (ICF

AND LHB DESIGN)”.. The following schedules and procedures must be

properly accomplished for equipment warranty conditions to apply. This

scheduled maintenance shall also assist in maintaining product performance

over an extended period of time.

1.2

THEORY OF FIRE

In order that a fire can develop, the following conditions must be present in the correct mixing ratio: - Combustible material Energy for igniting and maintaining the fire - Oxygen (O2)
An effective Fire fighting system should have the two basic sub systems.
 Early detection system for Smoke and Heat  Highly reliable Suppression System
The Detection System and the Suppression System, may or may not be inter connected.
DETECTION SYSTEM

In order to reach an optimal level of safety for the fire protection onboard rolling stock it is essential to choose the most suitable fire detection system. The selection of system is depending on the formal requirements as well as the fire safety risk assessment which must cover all areas where there is a potential fire risk.
Regarding the risk analysis there are different risks or scenarios to consider e.g. the fire hazardeous combustable material that is used in the area to be protected. The type of material, the expected igniter, humidity, air flow, air pressure etc will have an influence on the smoke, heat or flame generated which in turn gives the guidance on what kind of detection system that is required.

A Point Detection System consists of one or more redundant central unit(s) with one or more addressable communication loops on which several detectors selected depending on the risk analysis are installed.
The sensitivity and type of detector for each detection point is completely independent from the other detection points. If different products of the fire can occur, detectors sensitive to smoke, heat, flame etc can be installed in parallel or integrated in each detector. When smoke, heat or flame is generated by a fire and reaches over the defined level (or a product of several alarm criteria) an alarm is activated.
SUPPRESSION SYSTEM
In order to fight a fire effectively, the above conditions have to be removed – at least in part – from the combustion process. As a rule this is achieved either by means of cooling, and therefore the removal of energy, or by reducing the oxygen that is available.
PRINCPLE OF HIGH PRESSURE WATER MIST SYSTEMThe most important effects of fire fighting with water mist are

the cooling and oxygen displacement effect.
COOLING EFFECT
Through the atomization of water under high-pressure, the reaction surface available for the cooling process is significantly enlarged in comparison to conventional low pressure systems. As a result, SANROK systems can remove energy from the fire considerably faster and more effectively. As a result of the high cooling effect, the fire is effectively fought and people and materials are protected against the effects of heat. The high cooling effect is mainly achieved by vaporisation of the fine water droplets in the vicinity of the fire. This effect is supported by the shielding effect of the small droplets against heat radiation. In this way it is also possible to create effective water mist partitions (curtains) for building elements, wall openings, facades etc.

OXYGEN DISPLACEMENT
Due to the high temperature levels in the immediate vicinity of the fire, the small droplets evaporate very quickly and thereby remove energy from the fire. In the neighboring areas to the fire no steam is produced by vaporisation, ensuring safe evacuation of the area. As a result of the evaporation of the water in the direct vicinity of the fire its volume is increased 1640-fold, so that part of the oxygen is displaced locally at the seat of the fire. As a consequence, an inerting effect is produced at the seat of the fire, similar to that of an inert gas system.

However, in contrast to the use of inert gases, the oxygen concentration is not reduced throughout the room. In comparison to low pressure water mist systems or other conventional water fire fighting systems, the extinguishing effect is far more effective due to the small droplets used with the high-pressure technology, so that a much smaller quantity of water is required. The system pressure of 50 to 200 bar is required to create the small droplets and convey these with the required energy to the seat of the fire.

Fire Detection System

The fire detection system consists of 2 Nos Fire and Smoke

Detectors placed suitably inside the Generator area. The

Detectors are connected in a redundant loop to the control

module.

The Control module is connected to an Audio Visual Sounder beacon for Alarm in case of a fire.
