Automatic fire detection system

O fire It is a combustion, i.e, an exothermic chemical reaction, normalmente autossustentada, from a combustible material and an oxidising agent. Is called by a fire the fire out of control in time and space. Combustion products are:

seta azul O hot dissipated to the environment (calorific);
seta azul The Flue gas, some invisible, the most common being water vapor, or e dioxide or carbon monoxide;
seta azul O smoke and aerosols which are not gaseous volatiles;
seta azul A light radiation related to the temperature and the embers;
seta azul Nonvolatiles. These various manifestations of combustion products allow the existence of different types of detectors or sensors. The success of the intervention to the associated detection is dependent on that type detectors. The detection of the fire will be more useful and effective as face early for ignition.

The configuration type of a SADI is as follows:



a Automatic fire detection system (SATI) It is a technical installation capable of recording a principle of fire, without human intervention, transmit the corresponding information to a central signaling and command (CDI - fire detection central), raise the alarm automatically, whether local and restricted, whether general, either the distance (alert) and trigger all commands (immediate or timed) necessary for fire safety of the occupants and the building where it is installed: close fire resistant doors, command lifts, controlling fire dampers, command automatic fire extinguishing systems (SAEI), commanding fans, command electricity, Unlock retainers, etc.

seta azul The technical aim of the verification process is to determine whether the systems are installed in accordance with the design and specifications of the manufacturer. The technician who installed should make a visual inspection to ensure that the work was performed correctly, the methods, materials and components used are according to this NT, and with the design and registered designs and operating instructions corresponding to the installed system.

NOTE: can be more than one entity involved in the process.


seta azul To ensure proper and continuous operation of the system, this should be regularly inspected and assisted. Appropriate action to that effect should be taken immediately after the installation is complete or the facilities are occupied or not.

Generally it should be made an agreement between the owner of the work or user and the manufacturer, supplier or other competent authority for inspection, Service & Repair. The agreement must specify the connection forms suitable to provide access to facilities and the period in which the equipment should be put back in working order after a fault. The name and service business phone number should be posted prominently on the CDI.
