Maintenance of the fire alarm system
The fire alarm system is a Basic Element in a security system of any enterprise. Systems of the fire alarm system it is constantly improved, new ways of detection of the fire are invented, the percent of false alarms decreases. At any enterprise, at each office it is necessary to have such system. It is dictated as desire of the owner to secure the property, life and health of employees, and in state standards and regulations of the Ministry of Emergency Situations.
In general the fire alarm system is intended for identification of the fire at an initial stage of ignition and a signal transmission of alarm on the receiver, start of the warning system of people about the fire, and also puts in action installations of automatic fire extinguishing, system of smoke removal and other fire-prevention automatic equipment.
Systems of the fire alarm system are subdivided into places of ignition, analog and address on a way of positioning.
Analog systems determine the place of the fire by number of a fire loop. On one loop there can be about 30 fire sensors. On it, the accuracy of definition of the place of the fire decreases. On the other hand it is not important for small rooms, and the cost of all elements of the analog alarm system is less address by 2-3 times. Besides this system of the fire-prevention alarm system is significantly simpler when carrying out commissioning.
The address fire alarm system unambiguously indicates the place of emergence of the fire. It is modern and highly reliable system. On large objects this type of alarm systems is irreplaceable. And, despite the high cost of components, often, its application comes out cheaper. According to standards of address sensors is established twice less, than analog. It means, as materials it will be required less and installation works will be reduced in volumes.
There is also a mixed type address and analog system of the fire alarm system.
