Abstract
In this article investigated the cause of error through survey to building officials for minimizing the unwanted alarm of automatic fire notification and suggested countermeasure for minimizing the unwanted alarm. The main cause of the unwanted alarm is defective fire detector, interlocking with automatic fire detection system, lack in fire safety warden's ability, worn-out fire detect receiving system. The countermeasure for minimizing unwanted alarm is firstly, tightening up the standard of model approval, Secondly, interlocking with cross-section circuit method fire extinguishing system or realizing automatic fire notification system interlocking with home network, thirdly, tightening up licensing examination of fire safety warden, lastly, it suggested term of use rule of fire detect receiving system.

2. Countermeasures to minimize malfunction of automatic fire detect receiving system.
Malfunction cause and countermeasures to minimize malfunction that is based on questionnaires aimed at the persons concerned in building that the fire detect receiving system was installed is as follows:
2.1. Criteria reinforcement for type approval of the fire detector.
In case that the fire detect receiving system functions, notwithstanding that a fire safety warden should take a measure for the sake of the fire extinguishing, notification, evacuation, the persons who keep an eye out immediately whether fire actually occurred first of all occupied not only 78%, but also occurrence of malfunction occupied 22% because someone handled the fire detect receiving system, and the persons who should take the tranquilizing measures occupied 51%. These facts are grasped as phenomena that are appeared by increasing of malfunction rates of the automatic fire detect receiving system owing to the faulty sensor that receives the signal fire. It is necessary to prepare how to decrease malfunction
rates by improving the high quality of the fire sensor, strengthening the type approval standard of the fire sensor as a complementary countermeasure.
2.2. Interlocking with gas type fire extinguishing system of cross-section circuit method.
The automatic fire notification system can decrease malfunction due to the fire sensors via system improvement to be interlocked with the existing automatic fire detection system. Whenever only a fire sensor is functioned, in case that only one sensor function, after the sensor circuit method is interlocked with the fire protection system such as the automatic fire detection system and preaction sprinkler system, gas type fire extinguishing system, when more than 2 sensor circuit was functioned, it is necessary to decrease malfunction that is occurred because of the fire sensor by telecommunicating fire signal to the automatic fire detect receiving system after altering to the method that telecommunicate fire signal[4].
Table 2 2.3. Embodiment of the automatic fire
notification system that was interlocked with home network.
Opinions that performance of the fire protection system should be improved in order to prevent malfunction of the automatic fire notification system was the most as 32%. Because the existing automatic fire notification system is functioned by receiving fire signals from the automatic fire detection system, it is difficult to secure reliability for fire[5]. In a questionnaire survey, just like 18% of respondents respond that should be included to home network. The existing automatic fire detection system is necessary to judge accurately whether actual fire was occurred or not, interlocking with the video camera
images as a security system in order to receive the fire warning signal via heat sensors and smoke sensors of the existing automatic fire detection system [6].
2.4. The qualifying examination strengthening of the fire safety warden.
In case to be confirmed that the automatic fire notification system was malfunctioned, ratio to be restored according to self investigation and the way how the concerned persons handled the situation is the most as 64%, and ratio that measures are taken contacting to fire-fighting facilities management company was investigated as 24%, but the meaning of self-investigation mean level degree that block out power source of the automatic fire notification system, and capability that can grasp it's cause and cope with itself seems to be insufficient[7].

warden operate the automatic fire notification system and should carry out jobs such as composition of the initial response system, operation and management, education, evacuation shelter's facilities, fire compartment and maintenance management of fire-prevention system, but job performance of fire safety warden is grasped to be low[8]. And also opinions that professional education for the concerned persons in order to prevent malfunction of the automatic fire notification system is necessary occupy a large numbers as 24%. Therefore it is necessary to strengthen theory-centered education, decision of the success or failure from a written examination, fire notification, problems for shortage of evacuation course, practical service centered education, alteration from assessing methods to theory and practical training, fire notification and evacuation course as educational course[9].
2.5. Regulations on a service life of the automatic fire notification system.
Opinions that main cause of malfunction of the automatic fire notification system is occurred on account of deterioration of facilities are the most as 45%. In case of the current automatic fire notification system, once the current automatic fire notification system is installed, unless someone build a new building, and also before the building demolition, because the cases that the automatic fire notification system continue to be maintained are plenty of, the cases that be reluctant to alternate on account of cognition as so-called unnecessary facilities and consumption of high cost, although alternation is necessary is occurred [10]. Therefore regulating a service life enough to be criteria of the automatic fire notification system, the deteriorated automatic fire notification system is necessary to enforce by defining by law so that the regular alternations for the automatic fire notification system may are achieved. In conclusion, as a countermeasure for minimization of malfunction, firstly, reinforcement of the type approval standard for the sake of quality improvement of fire sensors, secondly, instead of interlocking method with the automatic fire detection system, interlocking with gas type fire extinguishing system of the cross-section circuit method or embodiment of the automatic fire notification system to be interlocked with home network, thirdly improvement reinforcement of a qualifying examination for fire safety warden, fourth, regulation on service life of the automatic fire notification system for the sake of alternation of the old facilities and so on are necessary.

Аннотация
В настоящем исследовании в целях минимизации ложных срабатываний оборудования автоматической пожарной сигнализации в результате проведения опроса среди управляющих зданиями и частотного анализа определяются причины ошибок и предлагаются меры по минимизации ложных срабатываний. Основными причинами ложных срабатываний являются брак в пожарных датчиках, синхронизация с автоматическими системами обнаружения пожара, недостаточность навыков ответственных за пожарную безопасность, старение автоматических пожарных извещателей и т.п. В качестве мер по минимизации ложных срабатываний предлагаются, во-первых, ужесточение нормативов утверждения моделей пожарных датчиков, во-вторых, синхронизация с системами пожаротушения по методу перекрестного замыкания или реализация оборудования автоматической пожарной сигнализации, синхронизированного с домашней сетью, в-третьих, ужесточение квалификационных экзаменов для ответственных за пожарную безопасность, в-четвертых, определение сроков использования автоматических пожарных извещателей Ключевые слова: автоматическое устройство по оповещению при пожаре; устройство автоматического определения; метод перекрестного замыкания; домашняя сеть; ответственный за пожарную безопасность.
