Anonymous users2024-02-04Hello, dear, I am glad to answer for you that the electrical fire monitoring system has a fire alarm can self-check the monitoring equipment should be able to carry out functional inspection of the machine and the equipped detector (hereinafter referred to as the self-test), the monitoring equipment should not act during the implementation of the self-test, and the external equipment connected to it should not act. When the self-test time of the monitoring equipment exceeds 1 minute or it cannot automatically stop the self-test function, the self-test of the monitoring equipment does not affect the alarm function of the non-self-test part. The monitoring equipment should be able to manually check the working status of all indicators and displays on its audio devices and panels.

Anonymous users2024-02-01The standard of the Ministry of Public Security GA503-2004 "Technical Regulations for the Testing of Building Fire Protection Facilities".
Automatic fire alarm system.
Fire detectors.
Point-type smoke detectors.
It should act under the action of test smoke, output the fire alarm signal to the fire alarm controller, and start the detector alarm confirmation light; Detector.
The alarm confirmation light should be maintained until it is manually reset.
Linear beam smoke detectors.
When the dimming value of the beam reaches , the fire alarm signal should be output to the fire alarm controller within 30s to start the probe.
Tester alarm confirmation light.
Point-type and line-type temperature detectors.
It should act under the action of the test heat source and output the fire alarm signal to the fire alarm controller; The point detector alarm should be activated by the detector alarm.
Confirm the lamp and should hold it until manual reset.
Flame (or photosensitive) detectors.
It should act within the specified response time under the action of the test light source, and output the fire alarm signal to the fire alarm controller; Has an alarm.
The detector of the confirmation light should be activated at the same time as the alarm confirmation light and should be maintained until the manual reset.
Combustible gas detectors.
It should meet the requirements of Article and Article 1 of GB15322-94 "Technical Requirements and Test Methods for Combustible Gas Detectors".
Manual alarm button.
When triggered, the fire alarm signal should be output to the alarm controller, and the alarm confirmation light of the button should be activated at the same time; It should be possible to reset manually.
Fire alarm controller.
Fire Alarm Controllers (Regional, Centralized, General).
The fire alarm function, fault alarm function, self-test function, display and timing function, etc., shall comply with GB4717-93 "Fire.
The relevant requirements of Article 1 of the General Technical Conditions for Alarm Controllers.
When the main power supply is powered off, it should be automatically converted to the standby power supply, and after the main power supply is restored, it should be automatically converted to the main power supply.
The status of the primary and standby power supplies is displayed.
Fire display disc.
It should meet the requirements of Article 17429-1998 "General Technical Conditions for Fire Display Disk".
Fire linkage control equipment.
It should comply with the requirements of GB16806-1997 "General Technical Conditions for Fire Linkage Control Equipment".
Beg. When the connection between the fire linkage control equipment and the input and output module is broken or short-circuited, it should be able to send out fire within 100s.
There is a clear difference between the sound and light fault signals of the disaster alarm signal.
Combustible gas alarm controller.
Combustible gas alarm function, fault alarm function, machine self-test function, display and timing function, etc., should be complied with.
GB16808-1997 "Technical Requirements and Test Methods for Combustible Gas Alarm Controllers" Article 1.
When the main power supply is powered off, it should be automatically converted to the standby power supply, and after the main power supply is restored, it should be automatically converted to the main power supply.
The status of the primary and standby power supplies is displayed.
Fire alarm device.
After receiving the control signal output by the fire alarm controller, an audible alarm or an audible and visual alarm should be issued.
Where the ambient noise is greater than 60dB, the sound pressure level of the acoustic alarm should be 15dB higher than the background noise.
Also: see section for detection methods.

Anonymous users2024-01-301.The alarm accuracy is high.
2.Real-time identification and alarm of smoke and flame.
Based on intelligent analysis and deep learning neural network technology, smoke and flame real-time identification and early warning, the alarm signal can be displayed in the monitoring client interface, and the alarm information can also be pushed to the mobile terminal, and the alarm lights and alarm signals can be driven to prompt the user to deal with them in time.
3.All-weather operation, stable and reliable.
4.Alarm storage function.
5.The product is easy to update and upgrade, and the investment income is improved.
Users do not need to change devices when they change applications, and only need to upgrade and update firmware and authorization files, and can directly use new functions to meet new monitoring needs.

Anonymous users2024-01-29The brand is different, the technical parameter requirements are different, the ** will be different, you may not be able to find a specific answer to this question.
Including, the automatic fire alarm system is composed of a trigger device, a fire alarm device, a linkage output device and other auxiliary function devices, it has the ability to produce smoke, heat, flame and other physical quantities produced by combustion in the early stage of the fire, through the fire detector into an electrical signal, transmitted to the fire alarm controller, and at the same time in the form of sound or light to notify the fire layer and the upper and lower adjacent layers to evacuate, the controller records the location of the fire, the time, etc., so that people can find the fire in time, and take effective measures in time, Extinguishing the initial fire and minimizing the loss of life and property caused by the fire is a powerful tool for people to fight against fire. >>>More
When the light is red, the monitoring instrument will automatically monitor the sidewalk. So as to capture pedestrians.
Oceanwide Sanjiang 9116 or on the host of the alarm bus association, how to check how much smoke and temperature feel hand report falls? If you look at the specific data, it must be displayed on his monitor, or on the display board.
The fire alarm system is composed of a trigger device, a fire alarm device, a linkage output device and other auxiliary function devices, which has the ability to produce smoke, heat, flame and other physical quantities generated by combustion in the early stage of the fire, and turns them into electrical signals through the fire detector, which is transmitted to the fire alarm controller, and at the same time shows the location and time of the fire, so that people can find the fire in time, and take effective measures in time to extinguish the initial fire and minimize the loss of life and property caused by the fireSo how to maintain the fire alarm system in the community? >>>More
The electrical fire monitoring system is characterized by an early warning system in terms of leakage monitoring. Different from the traditional automatic fire alarm system, the electrical fire monitoring system gives early warning to avoid losses, while the traditional automatic fire alarm system is to reduce losses. Therefore, this is the fundamental reason why it is necessary to install an electrical fire monitoring system regardless of whether it is a new construction or renovation project, especially a unit that has already installed an automatic fire alarm system. >>>More
