Dry
Dry valve sprinkler systems are permanently charged with air and used to protect unheated premises such as warehouses, hangars, attic spaces and other areas exposed to freezing temperatures. When the system is set is charged with air, the minimum air pressure includes a safety factor to prevent potential main water pressure in stabilities from forcing the Dry valve clack open to allow water into the system pipework.
Automatic Fire Suppression System
Fire Suppression Systems are a combined detection and protection systems which can be used in Server Rooms, Telephone Rooms, Archives and other valued locations. Alphx R can supply, Install, Test and Commission of different types of Fire Suppression Systems.
Fire suppression is a term used to describe the use of inert gases and chemical agents to extinguish fires, also known as clean agent fire suppression systems. These clean agents are governed by the NFPA Standard for Clean Agent Fire Extinguishing Systems. Approval listings include UL, FM, SABS and MEA. Gasses we use include FM200, Novec, CO², Inergen and Argonite. The most common uses for gas fire suppression systems are in server and computer rooms, electrical transformer rooms, switch & generator rooms, MCC cabinets, archives, document stores, and medical and pharmaceutical applications.
We can provide an annual maintenance service to assure that, Fire Suppression Systems is functioning properly by a regular service visits.
Foam & Water System
A Foam-Water System is a special system of pipe connected to a source of foam concentrate and to a water supply. The system uses appropriate discharge devices to control and/or extinguish fires which require a smothering and cooling agent. The piping system is connected to the water supply through a control valve that is actuated by operation of automatic detection equipment that is installed in the same areas as the sprinklers. Foam-water systems are designed to distribute a foam-water solution to a specific hazard area for fire protection.
Examples: extraction plants, aircraft hangars and areas where flammable-liquid spill fires may occur. Upon exhaustion of the foam concentrate supply, water discharge follows and continues until shut off manually. Systems can be used for discharge of water first, then foam for a specified period, and then followed by water until manually shut off. The type and potential size of the hazard determines the number of discharge devices, type of foam concentrate, and foam-water discharge rate and duration. Characteristics of some flammable products may require higher densities and special foam liquid concentrates.
Ultraviolet Detector Ultraviolet (UV) detectors work by detecting the UV radiation emitted at the instant of ignition. While capable of detecting fires and explosions within 3–4 milliseconds, a time delay of 2–3 seconds is often included to minimize false alarms which can be triggered by other UV sources such as lightning, arc welding, radiation, and sunlight. UV detectors typically operate with wavelengths shorter than 300 nm to minimize the effects of natural background radiation. The solar blind UV wavelength band is also easily blinded by oily contaminants.
Near infrared (IR) Array flame detectors (0.7 to 1.1 µm), also known as visual flame detectors, employ flame recognition technology to confirm fire by analyzing near IR radiation using a charge-coupled device (CCD). A near infrared (IR) sensor is especially able to monitor flame phenomena, without too much hindrance from water and water vapour. Pyroelectric sensors operating at this wavelength can be relatively cheap. Multiple channel or pixel array sensors monitoring flames in the near IR band are arguably the most reliable technologies available for detection of fires. Light emission from a fire forms an image of the flame at a particular instant. Digital image processing can be utilized to recognize flames through analysis of the video created from the near IR images.
UV/ IR
These detectors are sensitive to both UV and IR wavelengths, and detect flame by comparing the threshold signal of both ranges. This helps minimize false alarms.
Applications
UV/IR flame detectors are used in:
- Petrochemical Facilities & Refineries
- Co-Generation Pants
- Aircraft Hangars
- Silane & Hydrogen Gas Storage
- Gas Turbine & Power Plants
- Gas Compressor Stations
- Warehouse
- Semiconductors
Monitors are designed to automatically discharge over a specific design area upon system activation. These are suitable for use in high risk areas such as tank farm facilities, aircraft hangars, offshore, refineries, chemical plants, and heliports.
Features
- The monitor and body of the oscillating unit are manufactured using either brass, bronze, stainless steel or gun metal.
- Arc of oscillation adjustable via 6 set points.
Automatic Fire Detection and Alarm System
Description of Automatic Fire Detection and Alarm System as follows:
- Conventional Fire Alarm System is a multi-zone fully transistorized automatic fire detection system.
- Multiplex Fire Alarm System also known as “semi addressable” system.
- Wireless Fire Detection System
- Fully Addressable Analogue Fire Alarm Control System – With the trend towards intelligent buildings and the need to reduce wiring in large installations, the company is using fully addressable analogue detectors and input/output modules.
Analogue-addressable fire alarm systems give details on individual detectors, whereas conventional systems only give information about specific circuits or zones. Addressable or “intelligent” fire alarm systems are designed for large commercial premises and more complex networked systems, since they are much more expensive and more complicated than conventional two- or four-wire systems, having increased flexibility, intelligence, speed of identification, and scope of control.
