Intelligent radio site fire alarm system
The present invention relates to a fire alarm system and, more particularly, to an intelligent fire site signaling device, which instantly informs predetermined users about a fire site and indicates the situation and the best escape by transmitting radio signals to enable them to escape quickly from the fire site or to combat the flames without delay.

 Due to the increasing security concerns in today's society, the demands for security in living and working places are constantly increasing. However, there are still many uncontrollable incidents, among which fires constitute an unforeseeable danger. Many people lose their lives due to fires. In fact, some fires are preventable and, if they are unavoidable, stupid death and injury can be avoided if the sources of flame can be extinguished and if people can escape from the fire sites in time once these declared.

 In large buildings such as office buildings, restaurants and residential buildings, fire detectors are generally placed on the ceiling in rooms to ensure the safety of users or residents. The function of the fire detector is to detect a rapid or abnormal rise in temperature. If the ambient temperature rises rapidly or reaches the predetermined high temperature, the fire detector emits an action signal to trigger an alarm so that people can quickly escape from the fire site.

 However, in some large buildings, because of the very large number of rooms, once the fire is declared, people are unable to know precisely where the fire is, so there is no there be no sure escape.

Therefore, they easily lose the best chance of escaping. In particular, in certain office buildings or restaurants, as the users are generally visitors or temporary or temporary occupants, even

<Desc / Clms Page number 2>

 if they are aware of a fire, they cannot know its exact location and they cannot escape it in time since they are not familiar with the premises, which increases the number of victims. In addition, as each device has its own lifespan, the fire detector does not fulfill its role because it cannot be known whether it operates normally. As a result, we cannot really ensure the safety of users.

 Thus, the present invention aims to propose an intelligent radioelectric device for signaling a fire site with the aim of solving the problems mentioned above.

 The main object of the present invention is to provide an intelligent fire site signaling device which instantaneously informs predetermined users of the fire site and indicates the situation and the best escape route by emitting radio signals to enable them to escape quickly from the fire site or combat the flames immediately, minimizing the risk.

 The present invention also aims to produce an intelligent radioelectric device for signaling a fire site having a learning function and capable of self-monitoring periodically to truly ensure the safety of users.

 The present invention further aims to provide an intelligent radio signaling device for fire sites comprising an automatic telephone signaling device for fire, capable of automatically reporting an incident to the police, however an alarm is triggered to evacuate people. once a fire has started.

 The present invention also further aims to provide an intelligent radio signaling device for fire sites, also having an emergency assistance search function, in which at least one call station located at a voltage-free location. a large building is used to perform the function.

 According to the present invention, a plurality of fire detectors are arranged in a large building, each fire detector having a specific sequential address code. Several route indicators are placed in pedestrian crossings and several emergency call devices are placed in areas of the building that are not powered. A main remote control station is used to establish the sequential address code by radio.
