The Commercial Fire Alarms Are Not A Choice But A Way Of Life
The 'father' of the commercial fire alarm is Henry S Parmalee (Connecticut) who had actually improved upon the idea generated by the Pratt patent and in 1874 the first automatics sprinkler head was launched, though not on industrial level. Pratt had patented the model as early as 1872. However, it was only in 1940 that this type of sprinklers was used as commercial fire alarms because of the cost involved. Those who used them, did so by saving on insurance costs, which were minimized as a result.
Prevention Is Always Better Than Cure
Today, commercial fire alarms are mandatory in all places where there could be/ is a congregation of a large group of people (more than 100); it is also mandatory in all the places, which are beyond some 75 feet from the possible access of the fire department station. This is how the commercial fire alarms have found a way in every building across the continent, i.e. schools, hospitals, shopping malls, cinema halls, hotels, etc. These are also mandatory in places where hazardous material is stored lest a fire can trigger further damage.
A good number of insurance organizations do not offer coverage unless commercial fire alarms are installed so the damage can be minimized in case of a fire both in terms of human and material casualty and hence, save the insurance company a bundle. As per the law requirement, every place, which can house and offer night accommodation, as well as places where 100 or more people can assemble under one roof will need to have commercial fire alarms installed on their premises.
The newest addition on the mantle of laurels is the ESFR sprinkler, which has been designed to fight the fire by suppressing the spread and rise of fire. These sprinklers are usually pre-programmed to start functioning when their heat sensors reach a certain level of temperature that would trigger them on. In this design, only the sprinklers, which receive the signals of the heat would start sprinkling water. The rest would be silent and inactive, lest the pressure of water would be diminished and the ability to quench the fire compromised.
For places that need special attention and cannot risk an accidental shower, there is a special type of commercial fire alarm systems, i.e. the dry systems. These systems usually have valves that are connected to special fire alarms which perform a little investigation of their own (with smoke detectors and heat detectors) to find out whether it is really necessary to turn the water on.
