Question 1: How to start a fire hydrant button on a common fire hydrant button Normal fire hydrant button is to wear four lines, two open pump lines and two lighting lines. There is no start and stop pump relay on the pump's secondary circuit diagram. Then how to achieve: 1. After the button is pressed, a signal (reported to the fire alarm) should be given to the firefighting center. At the same time, the pump must be started directly. 2. What is the most important point? How to light the light on the fire hydrant button? Although the terminal of the secondary circuit diagram is lighted, it is AC, and the light on the hydrant button is lighted with DC 24V. So how to achieve such a function?
Atlantic Pumps answered:
The four lines you mentioned refer to the four pump houses, not the signal lines, and the signal lines should be six. According to my knowledge, most manufacturers have two control rooms and three or four pump houses. Root, as long as you press the cancellation report, the control room will automatically receive the fire alarm. This logic written in the cancellation report has all the manufacturers' fire hydrant buttons have this function. This is also a basic function, so this is no problem. To realize that, speaking of the pump, the fire detection standard requires that both the control room and the site can start the pump, which is commonly referred to as the two types of starting pumps. If you wear four lines to the pump room, it's good to say that two It is a pump, and two are answers. Usually fire pump manufacturers will leave four terminals, two are started, two are the answer signals, if the pump is directly connected to the pump from 24v on the line, if it is a large current pump, it will need to connect A 24V relay that starts the pump by controlling the relay. As for the answer, the general connection has two kinds. One is to receive a relay. As long as the relay is activated, the answer lamp will be on immediately. The advantage of this connection method is convenience. The disadvantage is that it cannot directly respond to the pump condition. The pump is not up, or the pump is broken, but the relay is activated so that the light will turn on, which is usually the false answer. The second connection is directly connected to the pump. This connection will not give a false answer. Normally, the pump responds that the two terminals are normally open. Once the pump starts, it becomes passive normally closed. At this time, you can connect the positive (or negative) terminal of 24v to the first terminal, and then From the second terminal, go back to the cancellation report, so that when the pump is not started, the circuit is disconnected. Once the pump is started, it becomes a path, and the light is on.
Question 2: In the fire protection system, the wiring method of the hand button and the fire hydrant button is here. Here is the four fire hydrants.
Atlantic Pumps answered:
See system diagrams and product manuals. There are two possibilities for hand reporting: 1. The loop is a round trip; 2. A group of loops, a group of telephone jacks; 6 fire hydrant lines: 2 are coming from the loop of the alarm system. Root is from the pump room. The loop is for the fire control room signal; the pump room is for the pump and light.
Customer asks:
Hello, thank you for your answer. Is the line coming from the lower circuit referring to the power line? Is that line with 24V power?
And do I want to know that both the paper and the fire hydrant have a fire protection center to power? I used the omnipotent button in the hydrant button here. The next group is 17V and the other group is 24V. The other group is connected to the indicator and the buzzer. Will the group be to the pump?
Atlantic Pumps answered:
Your question: Does the line from the lower circuit refer to the power line, is that line that has 24V power?
You must confirm on-the-spot where the line came from. If it is coming from the alarm system circuit, you should also have a signal module among them (here the fire hydrant button is provided by the fire hydrant box manufacturer and not by the alarm equipment manufacturer. The signal module is directly connected to the loop bus. The two lines coming out of the signal input point are connected to a normally open terminal of the fire hydrant button. This is a passive dry contact signal.
Your question: And I would like to know that both the tabloid and the fire hydrant have a fire protection center to supply power?
The hand report is from the fire-fighting center. It is not a power line. It is an active signal line, that is, a return line, which is generally 24 VDC.
Fire hydrant button introduction: There are ten terminal blocks, which are two normally open two normally closed sets of light lines. A normally open and a normally closed group, that is to say, after you use this pay, you can't use it normally closed here. So there are only six terminals.
Six terminals of the fire hydrant button, two (a group of normally open) terminals are connected to the signal module of the alarm system, and are passive signals; there are two (a group of other side of a normally open) terminal is connected There are two (light line) terminals on the Kai pump line that are connected to the fire hydrant lamp line. The Kai pump line and the hydrant lamp line are from the pump house. Kai pump line is generally between AC24 ~ 30V, of course, there are AC36V, see manufacturers. The lamp line is generally uncharged. Only when the contactor of your pump is actuated will the voltage light be output.
