Among the firefighting systems capable of preventing, alerting, and suppressing fire, the automatic fire detection system provides safe evacuation guidance through the primary detection and early warning of fire, and controls the fire extinguishing and smoke control facilities linked to the initial fire extinguishing and fire fighting system. It is a firefighting system that plays a pivotal role in early suppression and determining the extent of fire damage.

According to the definition of terms in Article 3 of the Fire Safety Standards for Automatic Fire Detection Equipment (NFSC 203), fire receivers, repeaters, detectors, and transmitters are defined as the following as representative devices of automatic fire detection equipment. A fire receiver is a device that directly receives a fire signal from a detector or a transmitter or receives it through a repeater to indicate and warn the occurrence of a fire. A repeater is a device that receives a signal according to the operation of a detector, transmitter, or electrical contact and transmits it to the control panel of the fire receiver. A detector is a device that automatically detects heat, smoke, flame, or combustion products generated during a fire and sends it to a fire receiver. A transmitter is a device that manually transmits a fire signal to a receiver.

In general, when a fire occurs in a building such as a house or a building, it is installed in a fire fighting system for detecting and extinguishing the fire.

A conventional fire fighting system generally includes a detector for detecting the occurrence of a fire, a control device for receiving and processing information detected by the detector, an alarm device operated by the control device, a sprinkler, a fire shutter, and the like.

A plurality of the detectors are installed in various places for each floor in the building, and the plurality of detectors installed on each floor of the building are connected by wire to a repeater installed on each floor to transmit a detection signal. And the repeaters installed on each floor relay the information sensed by the detectors for each floor and transmit it to the control device. For this purpose, the repeaters installed on each floor are also connected to the wired control device, respectively.

The control device is typically installed on the lower floor (first floor) of a building and receives the sensing signals of the sensors through relays from the repeaters for each floor. In addition, the control device operates an alarm device such as a visual alarm according to the received fire detection signal to output an alarm signal, and controls driving of a sprinkler and a fire shutter.

Claims (3)

A plurality of detectors 50 installed for each floor of a building to detect a fire, and a plurality of repeaters 70 for receiving fire detection signals from a plurality of detectors 50 installed for each floor and installed on each floor of the building; In the automatic material detection facility 100 including a controller 90 for receiving the detection signal of the sensor 50 for each floor collected from the repeaters 70 and generating and transmitting an alarm signal,
Transmitter 30 and the transmitter 30 that is connected to at least one of the repeater 70 or the controller 90 and receives the alarm signal transmitted from the controller 90 and transmits it through LoRa communication It is configured to further include a visual alarm 10 that generates a flash by receiving an alarm signal through LoRa communication,
The visual alarm 10 includes a main battery unit 19 corresponding to a general battery and a solar battery unit 11 charged by indoor low light in order to supply power, but the main battery unit 19 and the solar The operation of receiving power by selecting any one of the main battery unit 19 and the solar battery unit 11 without using the battery unit 11 at the same time is performed,
The visual alarm 10 is preferentially supplied with power by the solar battery unit 11, and when the charge amount of the solar battery unit 11 is small, power is supplied through the main battery unit 19, but , when the voltage of the solar battery unit 11 is greater than or equal to the set return voltage, the solar battery unit 11 is selected to receive power, and when the voltage of the solar battery unit 11 falls below the set reference voltage, the main Automated material, characterized in that the battery unit 19 is selected to receive power, and when the voltage of the solar battery unit 11 rises above the set return voltage at all times, the solar battery unit 11 is selected again to receive power detection equipment.
