In general, a fire receiver is a device that receives a fire signal from a fire detector according to the Fire Act, sounds a main alarm and an earth alarm, operates a visual sensor, and notifies the main receiver of the fact of a fire if necessary.

There are P-type receivers that operate with signals through wires directly connected to fire hydrants and breaking news sets connected to each floor, and R-type receivers that reduce the number of wires required by converting various signals into digital signals in the case of large buildings.

The smallest P-type 5 circuit fire receiver is sometimes installed alone in business places such as restaurants, bars, and karaoke rooms.

In addition, in the case of buildings with sprinkler installations, there is a composite receiver with an associated signal added.

The power source of the fire receiver operates with AC 220V in normal times and operates with a 24V battery installed inside during a power outage.

As such, large buildings or places where a large number of firefighters work mainly use R-type receivers that can be managed by computer, and most small and medium-sized buildings where one firefighting manager (related person) works uses P-type receivers.

The R-type receiver is easy to connect to a computer and manages smart phone interlocking through a fire management server, but the P-type receiver does not have an external communication function.

Therefore, if there is only one person involved in the firefighting (building owner, resident, supervisor (manager), or specialized company), so that the P-type receiver cannot be continuously monitored and managed, the firefighting person cannot leave the office, or the firefighting person cannot leave the office. There was a problem in that there was a problem in fire management because it was late or could not cope with the fire signal that occurred at night or while on the job.

As such, the existing P-type receiver without a built-in communication unit needs to be equipped with a separate communication device for remote monitoring and control. In the case of installing the communication device, there was a fear that there may be a case of being subject to legal sanctions for accusation and accusation.

3 is an exemplary diagram of a fire detection (input) circuit connected to the P-type receiver shown in FIG. 1 , and FIG. 4 is a simplified diagram of the P-type receiver connected to the input circuit of FIG. 3 .

3 and 4 together, a plurality of fire detectors (21a, 21b, ...) and a transmitter 23 are connected in parallel to a signal line 22, a plurality of monitoring zones 20, and a plurality of signal lines 22 A P-type receiver (1) for monitoring the voltage level of

Here, there are eight monitoring zones 20 connected to the P-type receiver 1, and accordingly, there are 8 input circuits for inputting the monitoring voltage of the monitoring zone 20 to the P-type receiver 1 (input circuit 1 ~ input circuit). 8) will be described as an example

Here, if the wiring of the signal line for receiving the fire alarm is simply described, a plurality of fire detectors 21a, 21b, ... and the transmitter 23 are connected in parallel to the signal line 22, and the signal line 22 has related regulations A predetermined DC voltage according to , for example, a DC 24V voltage is applied from the P-type receiver 1 or from another power source.

The fire detectors (21a, 21b, ...) when flame, heat, or smoke from a fire is applied to a predetermined level or more, the internal resistance is sharply lowered or short-circuited.

The transmitter 23 lowers the internal resistance as the switch is closed by an external force pressed by a person who discovers a fire.

The P-type receiver 1 monitors the level of the DC voltage applied to the signal line 22, and when the internal resistance of the fire detectors 21a, 21b, ... or the transmitter 23 suddenly drops, the signal line 22 By detecting a voltage change where the DC voltage level drops from 24V to around 5V depending on the equivalent resistance, an alarm can be generated.

Specifically, the receiver 1 selects any one or more of a selector 30 connected to a plurality of signal lines 22 and a plurality of signal lines 22 connected to the selector 30 to monitor the voltage level. control the selector 30 so as to be able to, and output the voltage level on the display 40 to display it on the display screen, while transmitting it to the smartphone 3 through the fire management server 2 to display it on the smartphone screen It may be provided with a CPU (10).

To this end, the selector 30 and the CPU 10 are connected to three selection lines A, B, and C, and a binary combination of 0 or 1 of the selection lines A, B, and C (2 ³ ), when the selector 30 selects any one of the eight input circuits (signal lines), the selector 30 selects the voltage of the corresponding selection signal line 22 while a DC voltage of 24V is applied. A detection signal S1 is generated by detecting a change in level.

The detection signal S1 is an analog signal as a measurement value of the signal line voltage level, and is input to the CPU 10 through the selector 30 through one INPUT line.

Here, when the circuit inside the fire detectors 21a, 21b,... is short-circuited by the heat, flame, or smoke of a fire, a current flows and a voltage drop occurs, and the voltage level is determined by the characteristics of the fire detector.

On the other hand, since the voltage level may change due to line aging, voltage induction, aging of the fire detector, water leakage, etc., the voltage level change due to fire and the voltage level change due to non-fire such as aging are different from each other.

Firefighters can know whether a fire or non-fire alarm is reported by looking at the voltage level change that is equally displayed on the display 40 or the screen of the smartphone 3, so that they can take different measures when an alarm due to a fire or an alarm due to a non-fire occurs. In the end, human casualties can be reduced.

The CPU 10 converts this analog detection signal S1 into a digital signal by the A/D converter 12 built in the CPU 10 and outputs it to the display 40 to display it on the screen.

Through this, the voltage level change is displayed as a number or graph on the screen of the display 40, and the manager sees the trend of this number or graph and determines whether an alarm is caused by a fire or a non-fire alarm when an alarm occurs and takes different measures You get drunk quickly, which can reduce the number of casualties.

Unexplained symbols R1, R2, and R3 are resistors and C1 is a capacitor.
