Extended Coverage Sprinklers

Extended Coverage Sprinklers are intended for the protection of areas larger than those specified in standard installation rules and for specific light, ordinary, or extra hazard occupancies. Sprinklers are designed to protect ordinary hazard occupancies with a maximum coverage area.the standard distribution of sprinkler heads will not provide enough coverage. In these cases, extended coverage sprinkler heads can be installed to increase the spacing between heads. Extended coverage sprinklers have a water distribution radius of a little over 10 feet, so they can be spaced approximately 20 feet apart.                                                                   

Criteria for the location of sprinkler heads. First, sprinklers must be located so they are within the hot-gas layer that develops near the ceiling during a fire because activation occurs when the sprinkler head reaches a certain temperature. Second, they must be located so that the water that is discharged from the sprinkler is not disrupted or affected by construction elements such as beams, trusses, or soffits.The extralarge orifice produces the flows required to meet Light and Ordinary Hazard density requirements at lower pressures than standard orifice or large orifice sprinklers.The glass bulb operating element and special deflector characteristics meet the challenges of quick response extended coverage standards.During fire conditions, the heat-sensitive liquid in the glass bulb expands, causing the glass to shatter, releasing the pip cap and sealing spring assembly. Water flowing through the sprinkler orifice strikes the sprinkler deflector, forming a uniform spray pattern.

                                                             

Two Main Criteria For Location Of Sprinkler Heads

• Because fire sprinklers are heat activated, sprinkler heads must be located high up on or near the ceiling.
• Sprinkler heads must be unobstructed to provide maximum flow to the areas that need it. This means they cannot be blocked by beams, trusses, soffits, or any other elements of your building’s construction.

Residential Sprinklers

Residential fire sprinklers in all new one-and two-family dwellings and townhouse construc­tion statewide. For many years, installation of fire sprinkler systems has only been required in office buildings and multi-family dwellings. These sprinkler systems are proven to save lives and extinguish fires. Despite the statistics, home fire sprinklers have yet to become code-mandated in new-home construction, and few homeowners who have the option choose to include this life-saving investment in their home.A residential sprinkler system is designed to use just enough water to control the fire. Typically one sprinkler head discharges 38-40 litres of water a minute compared to a firefighter's hose at 1000+ litres a minute. This minimises water damage and a room protected by sprinklers can often be back in use within a couple of hours.Residential fire sprinklers are not expensive.The sprinklers themselves are small, neat and blend in with the decor. The heads are connected through a system of pipes to the water mains or an alternative secure source of water. Most rooms require only two sprinkler heads to afford complete protection. Residential Sprinklers for Fire Protection Service . fire sprinklers be included a standard feature in all new homes.

Deluge Fixed Fire Protection System

Deluge system is designed to protect high hazard areas containing a severe fuel hazard with a high heat release rate by bringing a large number of open sprayers into action simultaneously in the event of a fire. Deluge valve system comprises of a control valve, a sprinkler operated detection system and a dedicated water supply system. For small or confined high hazard risk areas, Multiple Controls can be used instead of sprinklers. Deluge system is similar to a pre-action system except the sprinkler heads are open and the pipe is not pressurized with air. Deluge systems are connected to a water supply through a deluge valve that is opened by the operation of a smoke or heat detection system. Deluge systems are used in the protection of large Aircraft Hangers as one primary means of fire protection.                                                    

Deluge fire sprinkler systems are used where special hazards create a concern for rapid fire spread. These systems provide a simultaneous application of water over the entire hazard to ensure fast and effective suppression of the fire. Water is not present in the piping until the deluge valve is tripped, reducing the risk of leakage or damage to unseen areas of the building. deluge fire sprinkler  system is to quickly wet down an entire hazard area to prevent a fire from spreading. They are usually used in facilities that contain hazardous materials such as: flammable liquids, chemicals, and explosives.Deluge pipe fire sprinkler systems feature open-type sprinkler heads attached to a dry pipe that is connected to a main water supply. Using an innovative detection system that recognizes smoke or heat, this fire suppression installation activates a valve that releases water to all sprinklers.

Advantageous for protection of collections and other water sensitive areas. This perceived benefit is due to a fear that wet system piping may leak, while dry pipe systems will not. However, the same potential for accidental water damage exists, as dry pipe systems will only provide a slight delay prior to water discharge while the air in the piping is released from the pipe.                      

Safety Fire Alarm System in india

The Alarm System has varied applications and is used across many industries for security purpose.The Fire Alarm panel is the component, the hub of the system monitoring inputs and system integrity, control outputs and relays information.Primary Power supply Commonly the non-switched 120 Volt Alternating Current source supplied from a commercial power utility. In non-residential applications, a branch circuit is dedicated to the fire alarm system and its constituents. "Dedicated branch circuits" should not be confused with"Individual branch circuits" which supply energy to a single appliance.Secondary (backup) Power supplies component commonly sealed, lead-acid storage batteries or other emergency sources including generators, is used to supply energy in the event of a primary power failure.Initiating Devices component acts as input to the fire alarm control unit and are either manually or automatically activated.

Fire detectors must be coupled with alarms. Alarm systems provide notice to at least the building occupants and usually transmit a signal to a staffed monitoring station either on or off site. In some cases, alarms may go directly to the fire department, although in most locations this is no longer the typical approach.

                                                        

Burglar alarm system kerala

Burglar alarm system consist of diverse sensors (detectors) and alarm control panel, with the function of intrusion detection and smoke detection, as well as summon aid in an emergency.The work of the home security system begins with the sensors and motion detectors. These devices are installed in different places that they monitor in their own ways. However, they send emergency signals to the control panel once they detect something that surpasses their tolerance level.The control panel of the system works like the brain and decide the next step of action. Basically, there are two different things that the control panel performs. It can set off an alarm located near the house to alert the     homeowner and the neighbors.The keyboard provided with the home security system enables the users to arm, disarm andprogram the security system according to their wish. Most of the time, users are given multiple keyboards so that they don't have to rush from one place to another to find the keyboard in emergency.

Emergency Lighting System

Emergency lighting is a self-descriptive term and is lighting for an emergency situation when the main power supply fails. The loss of mains electricity could be the result of a fire or a power cut and the normal lighting supplies fail. This may lead to sudden darkness and a possible danger to the occupants, either through physical danger or panic.

Emergency lighting is normally required to operate fully automatically and give illumination of a sufficiently high level to enable persons of all ages to evacuate the premises safely. Most new buildings now have emergency lighting installed during construction, the design and type of equipment is normally specified by the relevant local authority, architect or consultant.

The British Standard provides the emergency lighting designer with laid down guide lines which form the general basis for the designer to work to. British Standard BS 5266: Part 1: 2005 includes in its scope residential hotels, clubs, hospitals, nursing homes, schools and colleges, licensed premises, offices, museums, shops, multi-storey dwellings etc. Although this standard recommends the types and durations of emergency lighting systems relating to each category of premise it should be remembered that the standards are minimum safe standards for the types of premises and that a higher standard may be needed for a particular installation.

Type of system
Most emergency lighting schemes fall into one of the following categories : 

•  Non-maintained - The emergency light units only illuminate in the event of a mains failure
•  Maintained - The emergency light units are illuminated at all times using the same lamps for both normal and emergency operation
•  Sustained - The emergency light units are fitted with two lamps or two sets of lamps. One of which operates on mains 240V AC supply, the other which operates from the battery supply in the event of mains failure. It is basically a non-maintained system with the addition of mains lamps which should be illuminated whenever the premises are occupied

Fire Fighting System India

A fire fighting system is probably the most important of the building services, as its aim is to protect human life and property, strictly in that order.  

It consists of three basic parts:

•  fire storage tanks
• a specialised pumping system,  
• a large network of pipes ending in either hydrants or sprinklers 

A fire hydrant is a vertical steel pipe with an outlet, close to which two fire hoses are stored . During a fire, firefighters will go to the outlet, break open the hoses, attach one to the outlet, and manually open it so that water rushes out of the nozzle of the hose. The quantity and speed of the water is so great that it can knock over the firefighter holding the hose if he is not standing in the correct way.  As soon as the fire fighter opens the hydrant, water will gush out, and sensors will detect a drop in pressure in the system. This drop in pressure will trigger the fire pumps to turn on and start pumping water at a tremendous flowrate.

A sprinkler is a nozzle attached to a network of pipes, and installed just below the ceiling of a room. Every sprinkler has a small glass bulb with a liquid in it. This bulb normally blocks the flow of water. In a fire, the liquid in the bulb will become hot. It will then expand, and shatter the glass bulb, removing the obstacle and causing water to spray from the sprinkler. The main difference between a hydrant and a sprinkler is that a sprinkler will come on automatically in a fire. A fire hydrant has to be operated manually by trained firefighters - it cannot be operated by laymen. A sprinkler will usually be activated very quickly in a fire - possibly before the fire station has been informed of the fire - and therefore is very effective at putting out a fire in the early stages, before it grows into a large fire.  For this reason, a sprinkler system is considered very good at putting out fires before they spread and become unmanageable.  

Fire Alarm Systems Kerala

Types of Fire Alarm Systems

All Fire Alarm Systems essentially operate on the same principle. If a detector detects smoke or heat or someone operates a break glass unit (manual break point), then alarm sounders operate to warn others in the building that there may be a fire and to evacuate. It may also incorporate remote signaling equipment which would alert the fire brigade via a central station.

Fire Alarm Systems can be broken down into four categories:

• Conventional
• Analogue Addressable
• Addressable
• Wireless systems

Conventional Fire Alarm System

In a Conventional Fire Alarm System, a number of call points and detectors are wired to the Fire Alarm Control Panel in Zones. A Zone is a circuit and typically one would wire a circuit per floor or fire compartment. The Fire Alarm Control Panel has a number of Zone Lamps. The reason for having Zones is to give a rough idea as to where a fire has occurred. This is important for the fire brigade and of course for the building management. The accuracy of knowing where a fire has started is controlled by the number of Zones a Control Panel has and the number of circuits that have been wired within the building. The Control Panel is wired to a minimum of two sounder circuits which could contain bells, electronic sounders or other audible devices. Each circuit has an end of line device which is used for monitoring purposes.

Addressable Systems

The detection principle of an Addressable System is similar to a Conventional System except that the Control Panel can determine exactly which detector or call point has initiated the alarm. The detection circuit is wired as a loop and up to 99 devices may be connected to each loop. The detectors are essentially Conventional Detectors, with an address built in. The address in each detector is set by dil switches and the Control Panel is programmed to display the information required when that particular detector is operated. Additional Field Devices are available which may be wired to the loop for detection only i.e. it is possible to detect a normally open contact closing such as sprinkler flow switch, or a normally closed contact opening. Sounders are wired in a minimum of two sounder circuits exactly as a Conventional System. Loop Isolation Modules are available for fitting on to the detection loop/loops such that the loop is sectioned in order to ensure that a short circuit, or one fault will only cause the loss of a minimal part of the system.

Analogue Addressable Fire Alarm Systems

Analogue Addressable Fire Alarm Systems are often known as Intelligent Fire Alarm Systems. There are several different types of Analogue Systems available which are determined by the type of protocol which they use. The bulk of standard Analogue Detectors available are fairly stupid as the Detectors can only give output signals representing the value of detected phenomena. It is left up to the Control Unit to decide whether there is a fire, fault, pre-alarm or other. With a true Intelligent Analogue System each detector effectively incorporates its own computer which evaluates the environment around it, and communicates to the Control Panel whether there is a fire, fault or the detector head needs cleaning. Essentially Analogue Systems are far more complex and incorporate far more facilities than Conventional or Addressable Systems. Their primary purpose is to help prevent the occurrence of false alarms. With the Analogue Addressable System, up to 127 input devices i.e.: Smoke Detectors, Call Points, Heat Detectors, Contact Monitors and other interface devices may be wired to each detection loop. In addition to the 127 Input Devices, up to 32 Output Devices such as Loop Sounders, Relay Modules and Sounder Modules may be connected. Analogue Systems are available in 2, 4 and 8 loop versions which means large premises can be monitored from one single panel. Isolator units should be connected between sections of detectors as described for Addressable Systems.

Wireless Fire Alarm System

Wireless fire alarm systems are an effective alternative to traditional wired fire alarm systems for all applications. They utilise secure, licence-free radio communications to interconnect the sensors and devices (smoke detectors, call-points, etc.) with the controllers. It is a simple concept, which provides many unique benefits and is a full analogue addressable fire detection system without the need for cable.
