Do fire alarm system.
Common sense of pay-off: 1. The manual alarm button is generally together with the fire ** jack, so it is generally four lines. The two of the hand itself are the signal line, and the smoke detector.
is connected. The other group is the ** line.
2. There are generally 6 fire hydrant buttons: a set of signal lines + a group of direct pump lines for the button itself, and a set of alarm lines (there is generally an alarm bell in a place slightly higher than the fire hydrant button).
3. The reason why it is always said "general" is because there are a few design jacks and fire hydrant buttons together, and the alarm bell does not follow the fire hydrant button, of course, it is a very rare case.
4. Each loop signal line should be pulled back to the host separately. Broadcast and ** do not need to be separated, the power cord is best to separate the circuit.

The fire alarm line is a line that connects the fire automatic alarm host, alarm bell, manual alarm button and other fire-fighting equipment, which has an important safety and security role. The following will introduce how to put the fire alarm line up and down.
1.Pay-off method on the lead:
1) Find the installation position, then carry out wiring, pass the line through the interface of the main machine, pass through the wall plate and extend the wire head at the opening of the base layer;
2) Lead the end of the wire out of the waterproof casing and use a thin wire to pass through the casing upwards until it reaches the roof;
3) Fix the fire alarm wire on the thin wire with a wire tie, then slowly take the thin wire out of the casing, and pull the fire alarm wire to the roof.
2.Lead-down pay-off method:
1) Find the installation position, then carry out wiring, pass the line through the interface of the main machine, pass through the wall plate and lead out the wire head at the opening of the base layer;
2) Thread the fire alarm wire through the waterproof casing, then hook the wire with a thin iron wire, and slowly pull out the waterproof casing;
3) Pull out the wire and fix the fire alarm line as necessary to avoid vertical vibration or swing.
It should be noted that in the process of pay-off, the line should be kept clean and beautiful, and the safety and reliability of the line should be ensured at the same time, so as to avoid the line and equipment from being dismantled due to external forces.

Fire alarm 280 How to put out the line.
Dear users, hello First of all, fire alarm 280 is a fire alarm signal, and the answer indicates that the temperature in a certain area has reached or exceeded 280, and there may be a fire risk. In this case, we need to take timely measures, including laying out wires, extinguishing fires, etc., to ensure the safety of people and property. Pay-off refers to taking measures to break the cable line from the fire area at the fire scene to prevent the spread of fire and the occurrence of short circuits in electrical equipment.
When laying off, you need to pay attention to the following points:1Make sure it's safe:
Before setting off the wire, you should ensure your own safety and wear protective equipment to avoid dangers such as electric shock and burns. 2.Cut off the power:
Before pay-off, it is necessary to cut off the power supply to avoid the continued operation of the electrical equipment and cause more serious fires. 3.Select the appropriate pay-off point:
When paying off, it is necessary to select the appropriate pay-off point to ensure that the normal operation of other electrical equipment will not be affected after pay-off. 4.Use the right pay-off tool:
When pay-off, it is necessary to use appropriate pay-off tools, such as wire cutters, wire strippers, etc., to ensure the effect of pay-off and the safety of Hu Hui. In short, fire alarm 280 needs to take measures in time, pay-off is one of the important measures, need to pay attention to safety and correct operation. <>

Fire alarm 280 How to put out the line.
280 The steps of fire alarm pay-off are as follows: 1. Prepare tools: pay-off, wire stripper, wire puller, soldering iron, soldering iron cap, soldering iron terminal board, junction box, wire stripper, pay-off wire pipe, pay-off talking rod, pay-off screwdriver, etc.
2. Disassemble the shell of the alarm, check the internal structure, and determine the circuit structure and wiring method of the alarm. 3. Prepare for pay-off: check the pay-off wire to ensure that the quality and length of the wire meet the requirements, according to the line structure, connect the wire, clamp the wire puller, and then weld with a soldering iron to ensure that the line is firmly called and secured.
4. Install the alarm: When installing the alarm, the installation position of the alarm should be determined according to the requirements of use, the alarm should be fixed on the wall, and then the pay-off wire should be connected to the input and output ports of the alarm, and then the shell of the alarm should be covered back to complete the pay-off work.

It is four lines, divided into search and answer and two groups. A set of alarms, connected to the signal line; A set of starting pumps can directly start the fire hydrant pump and connect to the pump system.
As the name suggests, "weak current for fire fighting" refers to the weak current system used in fire protection systems, fire protection engineering, weak lifting equipment, etc.
The fire protection system (sometimes referred to as the fire alarm system, which is translated from English) generally consists of two parts, namely fire warning equipment and fire extinguishing equipment.
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
Install fire alarms:
The two signal lines are not divided into positive and negative poles (it is forbidden to short connect the two signal wires, although the wiring is not divided into positive and negative poles, but it cannot be directly short-circuited), as long as it is in the same circuit, the signal line can be connected at will, and the tree network can be. >>>More
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
