Everyone knows that when people die in fire, mainly due to panic. If not, it all could safely leave the building and does not receive any injuries. Another well-known fact - the effectiveness of firefighting training practically zero, as well as other propaganda. Especially in areas where there are many innocent people - stores, shopping malls. At the word fire, few can argue sensibly. In such situations, the system alerts help cope with uncontrolled public.
Installation of warning systems are regulated by relevant State standards. For example, in buildings with more people, or the height of 3 or more floors of a system for warning required. In order to monitor the performance of the system alert enough to check it periodically. Often the translation system is used for playing background music in such cases all the problems once opened. However, a more specific warning systems, such as the specific records that are subject to regular proveke. In special cases, when the number of people too much, and when the warning system routinely used for the normal functioning of the organization, using an automated self-control.
The main method of this control is to add a test signal, which is constantly present in all channels. Thus the sound inaudible. Plus, the majority of the speakers are not designed to reproduce these frequencies. The number of zones that are required to notify as well as the number of signal sources easily determined depending on the task that confronts warning system. Large manufacturers of alarm systems produce all that is necessary for registration of alarm systems. At the same time at a sufficiently low price available product of excellent quality (eg, products SHOW). In terms of major public address price increases significantly, but with this set of equipment can announce a huge building with hundreds of bands.
