| Sumario: | One of the ways that is aimed at reducing losses from fires is to detect a fire at the initial stage of its occurrence, which can be most effectively carried out only with the help of fire automation systems. The latter includes information and measurement systems (IMS) of fire alarm systems, which are part of the fire detectors. Fire alarms (FA) are triggered by the appearance of primary signs of fire, transmitting a signal to the fire alarm control and indicating equipment (FACIE) through the appropriate loop. The FACIE processes these signals and forms commands for further actions, for example, sending alarm signals (sound and/or light) by fire alarms to warn people of danger, transmitting alarm notifications to the fire station and/or centralized fire monitoring console, as well as enabling and/or disabling certain equipment or engineering systems (including fire protection systems). Fire alarm loops (FAL) are electrical circuits that connect the output links of the FA, which include auxiliary remote radio elements and conductors, and are intended not only for issuing notifications about their status to the FACIE, but also for supplying power to these detectors. The reliability of the functioning of such IMS directly depends on the correct choice, according to the appropriate methods, of the nominal value of auxiliary hinged elements of loops, problems that arise during the use of equipment from different manufacturers. |
