Fire alarm system

A fire alarm system is a set of equipment and combination of technical tools installed at one site and controlled from a single fire alarm console. 

Fire alarm systems are intended for fire detection, processing and transmission (in set form) of fire notification and specialized data, and giving of orders for activation of automatic fire extinguishing units and activation of execution units of smoke protection systems, technological and engineering equipment, and other fire protection units. 

Types of fire alarm systems 

Non-addressing systems 

Signaling devices in such systems are represented by a quite complex electronic component which independently takes decisions on signaling 'fire'. They are cheap due to the usage of quite inexpensive electronic parts. Receiving and controlling units in such systems are simple, their primary functions, as a rule, being execution of operation scenarios depending on the type of signals received from signaling devices. 

Addressing fire alarm systems 

Addressing systems use signaling devices similar to those in non-addressing systems. The main difference is the addition of a unit that translates 'fire' and 'malfunction' signals to digital codes which contain information on signaling device's address. The main advantage of such systems is the possibility of exact identification of fire origination place within short time, because the console monitor displays location of the signaling device which has transmitted alarm signal.
