Technical Field
[0001] This utility model belongs to the field of fire protection equipment technology, specifically relating to a building room linkage fire alarm system that prevents accidental activation. Background Technology
[0002] Traditional gas extinguishing system controllers, unlike traditional fire alarm systems, cannot provide monitoring capabilities. They are relatively independent automatic extinguishing systems. Gas extinguishing systems typically employ three control modes: automatic, manual, and mechanical emergency. Therefore, fire alarm systems, usually located in remote fire control rooms, cannot remotely start or stop these systems; they can only receive alarm signals. Furthermore, the manual and mechanical control devices require rapid response and unrestricted button operation.
[0003] When a detector in the protected area of a gas extinguishing system alarms or when the controller outside the protected area is manually opened in preparation for activation, the fire control room needs to know immediately whether there is a fire hazard at the scene and be able to promptly and effectively dispatch personnel to the scene for handling. Summary of the Invention
[0004] The purpose of this utility model is to provide a safe and reliable building room linkage fire alarm system that prevents accidental activation.
[0005] The building room linkage fire alarm system for preventing accidental activation provided by this utility model includes an alarm box, an in-room warning system, an in-room fire extinguishing system, and a remote monitoring and control device. The room alarm system and the room fire extinguishing system are installed in one room; the alarm box is located outside the room. The alarm box is equipped with an alarm button and has a flip cover without a locking function to cover the alarm button; the flip cover is equipped with a door magnetic sensor for monitoring the opening and closing status of the flip cover. The room alarm system includes an alarm control unit, alarm lights, speakers, and cameras; The room fire extinguishing system includes a fire extinguishing main control device and a spraying device; The remote monitoring and control device is installed in the fire control room of the building and is remotely connected to the main control device of the warning system in the room. The main control device controls the connected alarm lights, speakers and cameras. The alarm button in the alarm box is connected to the fire extinguishing main control device. After receiving the signal from the alarm button, the fire extinguishing main control device can open / close the spray device to spray fire extinguishing gas or liquid. The door magnetic sensor in the alarm box is connected to the alarm control device of the room alarm system. After receiving the door magnetic sensor's flip-open signal, the alarm control device activates the alarm light, speaker and camera of the room alarm system, and sends the room alarm system activation signal to the remote monitoring and control device.
[0006] Furthermore, the remote monitoring and control device is directly connected to the door magnetic sensor of the alarm box, and receives the door magnetic sensor's flip-open signal to achieve dual signal confirmation with the room's alarm system.
[0007] In this invention, the alarm light inside the room is located at the doorway of the room.
[0008] In this invention, an alarm light is installed outside the room. The alarm light is connected to a door magnetic sensor. When the flip cover is opened, the alarm light is activated to alert people outside the room that the spray device will be activated in the room.
[0009] In this utility model, there are several sets of alarm boxes, outdoor alarm lights, indoor warning systems and indoor fire extinguishing systems, each set is installed in a different room.
[0010] In this invention, the connection between the remote monitoring and control device and the room alarm system can be achieved by pre-setting conduits during building construction and connecting via wired or wireless networks.
[0011] For equipment rooms in a building with special fire safety requirements, fire extinguishing devices are pre-installed in the rooms and remotely connected to the building's fire control room via a main control device. According to relevant regulations, the fire control room cannot actively intervene in the control of the fire extinguishing devices in the rooms; they must be activated by an alarm button in the alarm box at the room's entrance. The alarm box, according to regulations, cannot be locked and must be kept open at any time by anyone. If the alarm box is opened and the alarm is triggered, and there is no fire in the room but people are still working, the activation of the fire extinguishing device and the spraying of extinguishing gas could cause harm to the people.
[0012] When this utility model is used, for equipment rooms in a building with special fire protection requirements, alarm lights, speakers, cameras, and fire extinguishing devices are pre-installed in the room. In the event of a fire, if someone opens the flip cover and presses the alarm button: The door magnetic sensor of the alarm box will send three signals: one to the remote monitoring and control device in the fire control room, informing the personnel in the fire control room that there may be a fire in the corresponding room; another signal is sent to the alarm light outside the room, activating the alarm light to flash; the third signal is sent to the main warning control device, activating the alarm light, speaker and camera inside the room, prompting the people in the room to leave the room immediately through sound and light. The alarm button on the alarm box sends a signal to the main fire suppression control device in the room. The main fire suppression control device is activated and starts timing, giving the fire suppression device a certain delay time to allow people in the room to evacuate. After receiving the alarm signal from the alarm box, personnel in the fire control room can remotely connect to the warning control device in the corresponding room, observe the fire situation in the room through a camera, and remotely remind people in the room to evacuate through a loudspeaker; they can also contact relevant staff in the vicinity of the building to rush to the alarm room and organize rescue. If someone accidentally opens the alarm box cover, or intentionally opens the cover and presses the alarm button, resulting in a misoperation: After receiving the alarm signal from the alarm box, personnel in the fire control room observe through the camera that there is no fire in the room and determine that the alarm box cover was accidentally opened and triggered. They can then send a signal to the main control device to cancel the alarm, turn off the alarm light and the alarm sound of the speaker, and remotely remind the people in the room through the speaker. They can also contact relevant personnel in the vicinity of the building to go to the alarm room for further on-site confirmation, and manually turn off the alarm button and cancel the fire extinguishing equipment.
[0013] The advantages of this invention are that it can effectively and quickly organize fire rescue in buildings, improve fire extinguishing efficiency, prevent misoperation or malicious operation, and reduce losses. Attached Figure Description
