Which systems can be linked in actual engineering design?

Fire linkage control Fire linkage control includes monitoring of fire hydrant system, spray pump and spray pump, positive pressure fan and smoke exhaust fan, state monitoring of fire damper and smoke exhaust valve, fire emergency power-off system monitoring, elevator forced landing, fire shutter door and combustible gas monitoring, background music and emergency broadcasting and fire communication equipment monitoring, and fire power supply and line monitoring. The linkage control is completed by linkage repeater, and the drawing design is decentralized and centralized. The configuration advantage of linkage repeater is decentralization and centralization, and there is no need to change pipelines at all, which saves unnecessary expenses caused by line change. The linkage repeater FRR28Z-S of Nengmei R-22Z system is an intelligent repeater with CPU microprocessor. A repeater can carry four control signals and four return signals, but it only occupies one address in the host and can report four subaddresses, thus greatly saving the total capacity of the address, as described below: 1. Indoor fire hydrant system The setting of fire hydrant buttons in this project is completely in accordance with the design drawings. In case of fire, set fire hydrant button. The fire control center can also directly start and stop the corresponding fire hydrant pump manually, and display the working fault state of the fire hydrant pump, display the position of the fire hydrant button according to the fire zone, and return the working state of the fire hydrant pump at the fire hydrant button. This time, the monitoring of the fire hydrant button was completed through the energy FRR28Z-S linkage repeater. The manual direct control of the hydrant pump is realized through the linkage console located in the fire control center. 2. The water flow indicator and signal gate valve of each floor of automatic sprinkler system are monitored by FRR28Z-S linkage repeater with CPU microprocessor, and the linkage repeater has an independent coded address. When the contact of any water flow indicator or alarm valve is closed, its signal will be automatically displayed on the fire control panel, and the fire control center can automatically or manually start and stop the corresponding spray pump. The fire control center can also manually start and stop the corresponding spray pump directly through the linkage console, and can display the working and fault status of the spray nozzle. At the same time, when a fire alarm occurs, the fire control center can directly start the fire relay pump automatically/manually through the linkage repeater and console, display its working and fault status, and display the alarm water level when the fire water tank overflows and the alarm water level when the fire water pump stops. 3. Smoke prevention system The smoke prevention system is controlled by detection and induction alarm signals. When the detectors at the relevant positions send out alarm signals, the fire control panel will send out instructions according to certain procedures, and start the positive pressure blower, the air supply valve, smoke exhaust fan, smoke exhaust valve or smoke exhaust valve connected with the smoke prevention zone on the alarm floor and its upper and lower floors through the FRR28Z-S repeater. The fire control room can also directly start the positive pressure fan and smoke exhaust fan manually, and use the auxiliary contact of the main contactor to return signals to make them work. In case of fire alarm, the fire control center can directly and manually start the corresponding booster fans through the linkage console, and can automatically/manually start the booster fans on the refuge floor. The equipment of pressurized air supply outlet also has the function of manual opening on site. 4. The monitoring system of fire damper and smoke exhaust valve is controlled by detectors at all levels. When a detector in a fire zone sends out an alarm signal, the fire control panel will send out an instruction to cut off the air conditioner fan according to a certain procedure, and display its closed state through the data processing terminal. The signal of non-electric fire damper is also completed through FRR28Z-S repeater. In case of fire alarm, the fire control center can automatically open the 280℃ fire damper of the corresponding fire partition through the linkage repeater, start the corresponding smoke exhaust fan, and when the smoke temperature reaches 280℃, fuse and close the 280℃ fire damper at the fan entrance and turn off the corresponding smoke exhaust fan. When 280℃ normally closed fire damper and positive pressure air supply outlet are opened on site, the corresponding smoke exhaust (positive pressure fan) can be started directly. In case of fire alarm, the fire control center can automatically stop the air-conditioning fan in the relevant position, close the electric fire damper, and receive its return signal through FRR28Z-S linkage repeater. For the manual start and stop of smoke exhaust fans and pressurization fans, the fire control center can manually control the start and stop of all smoke exhaust fans and pressurization fans by using linkage repeaters and linkage consoles, and can return signals. 5. Combustible gas detection system The natural gas tube wells and natural gas metering rooms in this building need to be equipped with combustible gas detectors as required. When the combustible gas detector gives an alarm, the corresponding combustible gas pipeline cut-off valve will be automatically closed, and the corresponding exhaust fan will be started through the special combustible gas detection repeater of Nengmei. The alarm controller of the fire control center will automatically display the working status of the combustible gas pipeline cut-off valve and exhaust fan. Because the R-22Z controller has the compatible function of combustible gas alarm and has a special combustible gas alarm window, it can display the information of combustible gas detection and corresponding linkage control action very vividly and accurately. 6. The elevator homing and the corresponding access control fire control center are equipped with all elevator running state simulation and operation panels, which can monitor the elevator running state and remotely control the elevator through linkage repeaters. When a fire alarm occurs, the fire control center sends out a control signal, and all elevators return to the first place forcibly through the linkage repeater, and receive their feedback signals. When a fire alarm occurs, the fire control room can also cut off the power supply of the access control host on the corresponding floor through the linkage repeater, open the evacuation door on the corresponding floor and receive its feedback signal. 7. Fire shutter Fire shutter doors have two control methods. The principle is: controlled by sensor signal. When the relevant detectors send out alarm signals, the corresponding signals will be displayed on the fire control screen. At the same time, the shutter is closed through the interface unit, and the repeater returns the signal, so that the shutter switch state is displayed on the fire control screen. The first way is: smoke detectors and temperature detectors are arranged on both sides of the fire shutter door on the evacuation passage, and the descending mode is controlled twice, and the first descent is controlled by the smoke detector to stop at 1.8M from the ground; For the second time, the temperature detector controlled to drop to the bottom, and sent alarm and action signals to the fire control room respectively. At the same time, there is a remote control function in the fire control room. Fire shutter doors used for fire separation, such as around the shutter doors in underground garages, are only provided with temperature detectors on both sides of the shutter doors, and after the temperature detectors act, the shutter doors will descend to the bottom. The specific control mode of the shutter door in this project has been described in the chapter of optimal configuration. It should be noted that the fire control room and fire control center can display the alarm signal of smoke and temperature detectors and the closing signal of fire shutter doors. 8. Background music and emergency broadcast When the detector sensor sends out an alarm signal, the fire control panel sends out an instruction according to a certain procedure to force the background music to be turned into a fire broadcast state for emergency broadcast. The procedure is to switch between this floor, the second floor and the underground compartment when a fire alarm occurs on the first floor; If there is a fire underground, switch between the underground floor and the first floor. 9. When cutting off the fire alarm of non-fire power supply, the fire control center will cut off the non-fire power supply of relevant parts through the linkage repeater located at the site (implemented layer by layer), and turn on the fire emergency broadcast, fire emergency lighting and evacuation indicator light. 10. Fire fighting linkage console We provide linkage console in the fire fighting control room according to relevant specifications, which is assembled by piano platform to facilitate future expansion. The linkage control and working status of the following systems show that the production of linkage console and the number of all linkage equipment points are determined according to the engineering practice, which are non-standard products. A. Remote monitoring of fire hydrant pump, spray pump and spray pump b. Monitoring of positive pressure air supply and exhaust fan c. Elevator returning to the first position d. Linkage 1 1 is determined by relevant departments. The fire control center is equipped with CRT central graphic display system and color graphic display next to the fire controller. The microcomputer is an original brand high-quality commercial microcomputer, with 256MB of memory, expandable, hard disk over 30GB and hard disk data. The display records are all in Chinese (Windows operating environment); Equipped with 3.5-inch floppy drive, optical drive and 17-inch high-resolution color display screen; Equipped with 1000W UPS, Chinese real-time printer, and a full set of fire management software, all the fires in the whole project can be reflected on CRT and called up at any time. It is a graphic information display device networked with the main control computer in the fire fighting network. It has the same information display function as the main controller. Because CRT and NEOMEI R-22Z system are connected into a network, and its network technology adopts the internationally accepted Lonworks technology, the CRT system set in the fire control center can be transmitted through its advanced network, and all the information of the fire alarm controllers in the other two control rooms can be displayed at any time. 12. power supply and line monitoring R-22Z system can continuously monitor the standby power supply and the whole line through IC management card, and the linkage console and broadcasting system are equipped with special standby power supply. The power supply used in the fire center is 220V conventional power supply. 13. Communication system Two sets of fire communication systems are set up in this project. One set is a two-way fire communication telephone system, with fire telephone extensions in the main control room, computer room and other important rooms. The other set is a fire communication system, which consists of a telephone jack for manual fire alarm button and an alarm host in the fire control center. The specific quantity is configured according to the bidding requirements and design drawings. 7. Product performance parameters In order to give you a better understanding of the performance parameters of the main products of the R-22Z system, we have specially provided? Performance parameters and characteristics? . Eight, Beijing Guang Cai International Center disaster prevention equipment configuration, equipment selection and functional characteristics: 1, fire detector configuration selection and functional characteristics: According to the use function and characteristics of this project building, we recommend the following types of detectors: (1) FDK38Z ATF intelligent photoelectric smoke detector According to the design requirements of tender documents and drawings, the tenderee answers questions and answers questions, and all smoke detectors adopt Meimei ATF intelligent photoelectric sensors. The specific characteristics of FDK38Z ATF intelligent photoelectric smoke detector are as follows: FDK38Z detector has built-in CPU microprocessor chip, bidirectional digital transmission and can automatically detect the smoke concentration in the environment. Through the CPU intelligent chip, the smoke concentration data can be intelligently analyzed and judged, and the detected smoke information can be transmitted to the alarm host. The detector itself has electronic coding function, ATF automatic experiment function and environmental status display function at any time. The detector has the function of memorizing the detected data, and the displayed information can be called out at any time through the alarm host. The detector also has the functions of artificial intelligence, sensitivity adaptation, sensitivity automatic compensation and pollution degree alarm. Nengmei intelligent detector automatically tests without professional cleaning and soot blowing, which minimizes the maintenance and management costs of the owner in the future. Addressable ATF intelligent smoke detector is used in office area. Its purpose is to ensure that no matter how the office area is divided in the future, each detection area has an independent address, which greatly reduces the system changes when the secondary decoration is separated, and the system changes are convenient and simple. (2) FDL25Z ATF intelligent temperature detector is located in the place where boiling water or steam is generated on the floor, on both sides of the shutter doors of the underground garage and on both sides of the shutter doors of two tribes. The detector is characterized by high waterproof and moisture-proof function, thermal response characteristics, built-in CPU microprocessor chip, two-way digital transmission, automatic detection of environmental temperature change state, intelligent analysis and judgment of temperature change through CPU microprocessor, and transmission of information to the alarm host. The detector itself has the function of electronic independent coding, which can display the temperature change of the environment at any time through the host computer, and can be tested without heating through the ATF automatic experiment function. (3) FDK26Z9-X intelligent smoke detector This detector has a built-in CPU chip, which can directly set the alarm threshold of smoke concentration, and transmit the alarm information to the host computer by intelligently addressing the repeater location address. By reasonably configuring detectors, a lot of investment can be saved for the owners. In this tender, all intelligent detectors with independent addresses are described in the drawings, so we do not use such detectors in the bidding scheme. But this detector can be combined with ATF intelligent addressing repeater (FRR28Z-F) to form a mother-child detector, which can be used in shopping malls, large office areas, underground warehouses, public corridors, equipment rooms and some large areas in large buildings, and can be used to carry several standard smoke detectors. Therefore, at the end of this scheme description, we put forward two suggestions to save investment for the owner, and recommend that this kind of detector be used in an appropriate position with the owner's consent for the owner's reference. (4) FDL9 16Z8-W standard temperature detector is in the underground garage. This time, according to the design drawings, ATF Intelligent Addressing Repeater (FRR28Z-F) with multiple standard temperature detectors is adopted, which is recommended in this scheme. The detector has a special waterproof and moisture-proof function. The underground garage is divided into several alarm areas according to the smoke prevention partition of the garage, the actual distribution of the main beams and the corresponding fire codes, and each area is set with an independent address, which is located by addressing the repeater address and connected with about 20 standard temperature detectors. (5) In the combustible gas pipeline room in the building, Rip combustible gas detector is used this time. It is connected by the unique combustible gas repeater of Nengmei, with four outputs and four returns. 2. Other on-site disaster prevention equipment configuration (1) FMB 13Z-W manual alarm buttons According to the specifications and building layout, manual alarm buttons are set in public corridors, lobbies, public areas and underground garages as an emergency manual alarm once the fire is confirmed. When the manual alarm button is pressed, the fire center host immediately displays the alarm position, and the alarm display light on the button lights up at the same time. The manual alarm button can be reused, and the user does not need to specially configure the manual alarm glass. In addition, the manual alarm button also has a telephone communication jack, and firefighters can use this communication jack to directly talk with the fire control room. The model used this time is an intelligent alarm button with an independent address. Here we put forward a suggestion. Because the fire code allows the manual alarm button to be controlled by a single control or a fire zone, in order to save the owner's investment, the manual alarm button without independent address should be changed on the premise of meeting the requirements of the code and building functions. According to the fire partition, the repeater with CPU is connected to the host, which can save a lot of addresses and investment. Please refer to the proposal at the end of the scheme for specific suggestions. (2) Fire Direct Telephone Communication System In addition to the emergency call system provided by the fire alarm host, there is no direct telephone extension dedicated to fire protection in the elevator room, fire fan room, fire water pump room, power distribution room, air conditioning room, important office and other important computer rooms. The communication switchboard is located in the fire control center, and the personnel on duty can directly talk to the fire control center with the fire telephone extension, or the center can directly talk to the extension. In this scheme, it is recommended to use the special communication equipment for fire fighting of Ai Feng Company. (3) FRR28Z-F intelligent addressing repeater In this scheme, intelligent addressing repeaters are set in all areas that need signal feedback and linkage equipment (such as alarm partitions, fire dampers, smoke exhaust valves, water flow indicators, signal gate valves, etc.). ), through which the alarm host can display the alarm position and equipment action information in time. The repeater has built-in CPU, independent addressing, simple wiring, flexible installation and use, and can be connected with standard smoke detectors and temperature detectors, with automatic short-circuit isolation function, and can monitor the short-circuit and open-circuit faults of detector circuits. The repeater is small in size and convenient to install. It only needs to be installed on the base of the detector or embedded in the box, which is very convenient for debugging and maintenance. (4) FRR28Z-S intelligent linkage repeater for fire fighting equipment. All automatic fire-fighting equipment in this project, such as fire water system, fire smoke control system, power-off system, air conditioning system, elevator self-guidance system, fire shutter and fire door system, need to be automatically linked through this intelligent repeater, which is an important equipment of disaster prevention system. The important features of Nengmei intelligent linkage repeater are: built-in CPU microprocessor, bidirectional digital transmission, ATF automatic test, displaying the status of linkage equipment, having four linkage outputs and four input signals, but occupying only one address point of the system, saving system resources, providing convenience for expansion and maintenance, isolating input and output signals, adopting plug-in terminals, avoiding virtual connection and looseness, reducing wiring resistance and improving system reliability. Because the interface circuit has short-circuit isolation and optical isolation, in order to facilitate future equipment detection and maintenance, the repeater adopts the principle of relatively centralized placement.
