How to promptly warn and deal with fires

With the widespread use of electric energy, the number of fires caused by electrical appliances is increasing year by year. According to statistics, one third of the fires are now accounted for, ranking first in all fires. How to detect and control fires in time, effective early warning and treatment when the fire does not occur or just happened, this research direction is very meaningful in practical applications.

Since the Qin Dynasty, Guangzhou has been the political, military, economic, cultural and scientific center of South China. Since the 1930s, it has become the main port of the Maritime Silk Road. During the Tang and Song Dynasties, it became the big port of Zui, and the two generations of the Ming and Qing Dynasties became the big port of foreign trade. It is the big port that has been growing for more than 2,000 years in the world. With the development of the city, more and more people want to know about fire safety products, and the choice of fire safety products has become a problem faced by many people.

Having said that, do you think it is necessary to understand the fire safety products? Then let me take a look at the relevant information~

The following is an answer to the question "What is the use of the electrical fire monitoring host?" I hope to give some help to some friends who care!

Features:

1, monitoring alarm function

When the monitoring device receives the monitoring alarm signal from the connected detector and is in the alarm state, the monitoring device emits an audible and visual alarm signal, and the liquid crystal display displays the alarm location, type and time. This monitoring alarm state should be maintained until monitoring. The device can be reset by manual operation. For the alarm sound signal, it can be manually eliminated using the mute button. When there is a monitoring alarm signal input again, the monitoring alarm sound signal should be able to start again.

2, fault alarm function

When the monitoring device occurs short circuit, open circuit, detector communication failure and main power supply undervoltage between the detector, the monitoring device emits an acoustic and optical fault signal that is significantly different from the monitoring alarm signal, and the liquid crystal display shows the fault location. , type and time. The fault light signal and fault information should be maintained until the fault is removed, and the fault can be automatically restored. The fault sound signal can be manually eliminated by the mute button, and when a new fault signal is input, the fault sound signal can be started again.

3, self-test function

The self-test is a function check of all the functional components (including working status indicators, liquid crystal displays, audio devices, etc.) in the monitoring device. During the self-test, the equipment does not affect the normal operation of the non-self-testing parts.

4, alarm record storage query function

When leakage, temperature alarm or detector short circuit, open circuit and communication failure occur, the information such as the location, type and time of the alarm is stored in the database. When the alarm is released and the fault is eliminated, the recovery time is recorded. Quickly view alarms and fault logs with historical data.

5, monitoring function

Through the operation of the system software, all detectors connected to the monitoring device can be remotely controlled, including real-time monitoring, setting of alarm setting values ​​and remote reset of the detector.

6, permission control function

In order to ensure the safe operation of the monitoring system, the monitoring device system software operation authority is divided into three levels, and different levels of operators have different operation rights.

Operator: Real-time status monitoring, fault alarm silence, history query

Operator: Real-time status monitoring, fault alarm silence, history query, remote reset of the detector.

Administrator: Real-time status monitoring, fault alarm silence, history query, detector remote reset, monitoring device self-test function, remote modification of detector parameters, parameter setting and modification, operator addition and deletion.
