Firefighting System
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.
Firefighting, in computing, refers to the emergency allocation of resources that are necessary to handle an unexpected problem. The term implies that the effort goes into chasing bugs rather than integrating new features. This term can be spelt as either fire-fighting, firefighting, or firefighting.
A firefighting 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:
a large store of water in tanks, either underground or on top of the building, called fire storage tanks
a specialized pumping system
a large network of pipes ending in either hydrants or sprinklers (nearly all buildings require both of these systems)
Fire Alarm Systems
Defining the System :
Fire alarm systems have two jobs. It must detect a potential fire in a facility, and then notify its occupants. It’s that simple. Getting the system to work properly and meet local life safety codes; that’s not so simple. This article is the first in a series that will explain fire alarm systems to personnel that need to design them, as well as those that will interact with them after the facility is occupied.
The fire alarm control panel (FACP) is the origin of all fire alarm activity. Depending on the size of the installation, there may be a number of FACP’s in a system that talk to each other, but the basic premise is the same. The FACP controls all devices connected to it. What makes up an FACP? First, there must be a main control board. This board processes signals from the devices on its field circuitry and supervises all subcomponents for proper operation. These subcomponents include:
Circuit boards
Power supplies
System CPU
Initiating devices
Notification appliance circuits
Initiating the action :
We’ve discussed the two jobs of the FACP, detection and notification. Detection devices are also referred to as ‘initiating’ devices. An initiating device initiates an output of some type on the fire alarm system when activated. Examples of initiating devices are:
Smoke detectors
Heat detectors
Manual pull stations
Dry contact monitoring devices
