Notification System TECHNICAL FIELD TO WHICH THE INVENTION RELATES 5 This invention is for educational institutions (schools, kindergartens, universities) affiliated with the Ministry of National Education. administrative buildings, hospitals, shopping malls, industrial facilities, primarily, Emergency services are needed in all types of indoor and outdoor facilities, such as construction sites, security booths, and communal living spaces. It enables the communication of situations, security vulnerabilities, and corporate status reports; independent of the grid and general electricity infrastructure, via radio frequency (RF) infrastructure 10 The system has an action-oriented voice announcement feature and two-way verification (ACK). a mechanism capable of silent coverage control that prevents visual confusion It is related to the communication system. STATE OF THE ART School Safety and Early Warning 15 published by the Ministry of National Education and the Ministry of Interior Warning Circulars, Disaster and Emergency Management Instructions, and Law No. 6331 on Occupational Health and Safety According to Occupational Safety and Health (OSH) legislation; in educational institutions, employees who work uninterrupted during crisis situations, It enables rapid communication between school administration, duty teachers, and law enforcement. Establishing early warning and emergency notification systems is a formal requirement. However, the emergency notification systems used in existing public and private educational buildings are generally 20 via GSM (cellular network), Wi-Fi, Ethernet or wired intercom lines It is operational. Fire, earthquake, sabotage, physical security threats or energy transmission The general power grid is cut off during critical moments such as malfunctions in GSM base lines. congestion at stations or Wi-Fi access points being disabled As a result, emergency calls cannot reach the other party, and communication is completely cut off. 25 Another weakness in the current state of technology is that it exists in both wired and wireless systems. This is a "Silent Failure" problem encountered in emergency response systems. In wired systems, lines can break, oxidize, or be damaged by rodents or physical factors over time. 2 Damage from various factors or central panel power supply failures; in wireless systems, the battery. such as the unit running out of power, the transmitter module malfunctioning, or the unit going out of coverage area. These situations only occur when the button is pressed and the signal is transmitted to the other side in a real emergency. It becomes apparent when it doesn't reach its destination. Existing infrastructures determine whether the system is functioning properly. It does not have a two-way verification mechanism that tests in the background. 5 Furthermore, the current systems used in schools and institutional buildings are only tectonic standard. It gives a warning by emitting a siren or a high-pitched warning sound. This is especially true in situations where panic and chaos are high. In emergency situations (e.g., fire, health crisis, or security breach), only a siren is used. The theft is causing disorientation and uncertainty among administrators and staff; officials are concerned about the incident. It cannot provide guidance on the type of first aid that should be given. Last 10 As such, warning LEDs or sirens are used when performing connection and line tests in existing systems. activation; the administrative office, teachers' room or security room where the receiving unit is located This creates a false alarm perception among authorized personnel working in the unit and causes unnecessary loss of work. This causes confusion.

By fully complying with OHS requirements, the aforementioned infrastructure dependency, wired / wireless Eliminates silent failure, lack of routing, and false alarm problems on the lines. The goal is to provide an industrial emergency notification infrastructure that can handle emergencies. Thanks to this invention, the transmitter and receiver units are powered by mains electricity via an external power supply socket. It charges its internal rechargeable batteries while in operation, and provides uninterrupted service during power outages. It continues to be powered by batteries. The system uses radio frequency (RF) communication modules. It communicates wirelessly and without a network for distances of many kilometers. The receiver unit not only sounds a siren, but also provides audible prompts directing action specific to the nature of the event. Instruction announcements (e.g., notifying fire units or taking safety precautions) 25 (in that direction) is broadcast to ensure the right intervention during times of panic. In addition, devices can automatically activate timers or manually in the background. It performs periodic coverage tests. During the coverage test, the receiver's... No category LEDs or confirmation LEDs are illuminated, and the sound module is not operational; 3 Test results are communicated to the user only via the audible warning element (passive buzzer). This is communicated via audio tones at a specific frequency. Thus, during routine tests, the receiver unit... authorized personnel in the administration, teachers' room or security center where it is located Distraction, confusion of routine test signals with a genuine emergency call, and Visual confusion in authorized areas has been completely prevented. 5 EXPLANATION OF THE FIGURES  Figure 1: Front / External General View of the Transmitter Unit  Figure 2: Layout of Internal Hardware Components of the Transmitter Unit  Figure 3: Front / External General View of the Receiver Unit  Figure 4: Layout of Internal Hardware Components of the Receiver Unit 10 CORRESPONDING PARTS IN THE FIGURES 1.
