Addressable Fire Alarm Systems
An addressable fire alarm system is made up of a series of fire detectors and devices that are connected back to a central control panel.
With addressable systems, each device has an address or location, enabling the exact detector that was triggered to be quickly identified. This makes addressable alarm systems ideal for large buildings, particularly commercial premises spread over a wide area.
Conventional Fire Alarm System
A conventional fire alarm system will use fire detection zones (wired back to the main control panel). Each zone will identify a particular area of the building in order to identify the location of a fire.
Each zone can consist of various devices, including automatic smoke/heat detectors, manual call points, sounders and strobes. In the event of a fire being detected either automatically or manually, the system control panel will then operate the alarm.
Fire Suppression System
The exact type of automatic fire suppression system your business premises need is determined by several factors; the materials on site, the processes undertaken on site, the layout of your building, and whether humans are present in the environment you wish to make safe. All automatic fire suppression systems utilise sensory equipment to detect the signs of fire, and provide an immediate response to the problem in order to minimise its effects. The detection often involves the use of fire alarms, smoke detectors and heat sensors, and use water, inert gases or chemical agents to combat the fire.
The most common style of fire suppression system you will be aware of is the water-based sprinkler system, of which there are two types. Wet sprinkler systems are constantly ready with a full connection to a water supply, and are often set to automatically activate upon detection of fire or smoke. Alternatively a dry sprinkler system can be provided, which still combats a fire using water, but said water is located elsewhere and not present in the pipes at all times. This is a useful system if the risk area is particularly cold, but it does increase the response time of the fire suppression system itself.
Another fire suppression system involves the use of inert gas, which displaces the oxygen in a room and effectively smothers the fire. This is a useful system to have if you are worried about damaging electronics with a water based-system, and it is a common feature of computer server rooms. However, the potential asphyxiation dangers to nearby humans must be evaluated beforehand, and as such an inert gas fire suppression system often features prior warning to evacuate the area.
Automatic wet and dry chemical systems are another option if your building contains materials which prove sensitive to water or inert gases. Like inert gas systems a chemical response almost always comes with a built-in delay to allow time for employees to evacuate, since many fire suppression chemicals are hazardous to humans.
Firefighting is an emergency allocation of resources, required to deal with an unforeseen problem. In software development, for example, firefighting might involve assigning extra programmers to fix coding bugs that are discovered close to a product’s release date; in a security context, it might involve allocating resources to deal with the breach of an information system or the outbreak of a computer virus. At the individual user level, firefighting might involve dealing with hardware or software problems that could have been prevented with basic computer maintenance practices.
My Tech Engineering (Pvt.) Ldt Corporation can network / integrate this fire fighting system to your overall facility security panel for the best fire safety/ fire protection.
Kitchen Hood Fire Suppression
The Kitchen Hood Fire Suppression System is specifically designed for the suppression of fire in commercial
kitchen cooking appliances, plenums, hoods and ducts.
Each system operates automatically or may be operated
The system uses a liquid chemical as its agent. The agent
is a solution of potassium acetate involving:

The transformer area is best protected by an automatic high velocity water spray system (HVWS). This requires a special nozzle capable of handling fast delivery of fire water at high pressures (typically not less than 3.5 bars for outdoor transformers.) Care should be taken to place the nozzles, so that the spray patterns overlap each other, thus providing continuous coverage of the entire area with no gaps in protection.
Some transformers are now being manufactured with relatively high design temperatures. This can result in large amounts of heat being discharged from the unit by the cooling fans, which in turn, might inadvertently trigger the deluge system if rate-of-rise heat detection units are used in the system; Therefore, it is best to use fixed temperature heat detection systems to activate deluge fire protection systems in the transformer area.
