How to solve the fault of gst Gulf fire automatic alarm system

In view of the user's demand for the technical knowledge of the Gulf fire automatic alarm system, the insider specially sorted out and answered the technical knowledge questions of the Gulf fire automatic alarm system as follows, so as to facilitate the user to understand the Gulf fire automatic alarm system more directly.

1 and 8300 input modules, are the two buses always open, and when the equipment moves, the lines are closed to generate alarm signals? Is z 1 z2 polar? I port and G port are connected to the controlled equipment, right?

8300 input module, under normal circumstances, neither bus is normally open, but I and G feedback terminals can receive normally open or normally closed signals. Z 1 and Z2 have no polarity. 8300 is an input module, also called monitoring module, which is used to monitor the action of equipment, so I and G are connected to the monitored equipment.

2, 8300, how to set normally open detection line and normally closed detection line? What is the terminal resistance?

Setting normally open detection line and normally closed detection line in 8300 needs to be realized by encoder. Refer to the encoder manual for detailed operation steps. The terminal resistance is the resistance to realize the line inspection function, and the resistance value is 4.7KΩ.

3. Which equipment is always open for inspection? What are the normally closed detection lines?

In general, the equipment is always open for inspection, but rarely closed for inspection.

The starting current of 4.830 1 I/O module is very small, which is easily disturbed by lines or spaces, so it will cause misoperation. If used, an intermediate relay can be added. What is the use of intermediate relay? Did we add it on the spot?

Generally, the 830 1 module will not fail due to interference unless the module is damaged. When the module is connected with high-voltage equipment, an intermediate relay is used.

5. 830 1 Do you want to control the air supply valve and fire damper? Where do I connect the wires? What is the link order?

830 1 Control air supply valve and fire damper shall be connected with the valve actuator. The connection sequence depends on the design requirements.

830 1 module is normally open contact output, and module is impermanent closed point output.

7.830 1 how to realize the action transmission of signals?

It depends on what kind of motion transmission is realized.

The factory setting of 8.830 1 is normally open line inspection and passive output mode, so how to switch to normally closed line inspection? Will adding a relay make it an active output? What are the characteristics of active output? What is a relay race? What is the function of relay?

It is necessary to modify the parameters with the encoder to switch to the normally closed line inspection. Adding relay can be converted into active output. Relevant knowledge of relays can be found in Baidu Encyclopedia.

9. After the signal line is connected to the signal input end of 830 1 module, do you want to connect the field control equipment? If you want to connect a controlled device?

830 1 is connected to the controlled end of the controlled equipment, and receives passive feedback after the controlled equipment is started.

10, why can't the module be directly connected to the AC circuit? Isn't our power cord AC? How to understand DC and AC?

The module can only be connected to DC24V, and cannot be connected to other power sources, which is determined by the parameters of the module itself. For the difference between AC and DC, and the basic knowledge of AC and DC, please see Baidu Encyclopedia.

1 1, what's the difference between a bus and a power cord? The current of the bus is smaller than that of the power line? Why?

The signal bus of the alarm system is the communication line between the alarm controller and the equipment. The communication between the alarm controller and the equipment is generally to send patrol pulses regularly, and the power supply is a stable signal, so the relative current of the signal line measured by the electric meter is relatively small. 12, the output control modes are, pulse and level? What is a pulse? What is level?

Pulses are time-limited output signals. If the pulse width is 3 seconds, the signal output will stop after 3 seconds. The level signal outputs a stable signal.

13. What's the difference between active output mode and passive output mode?

Active output is to output a power supply, and passive output is generally based on normally open or normally closed contacts.

14. Is it necessary to add an intermediate relay to connect the shutter door and elevator with 830 1? Did we add it? Whether to add relay depends on whether DC24V control contact is reserved in the shutter door or elevator manufacturer's control cabinet.

15. What does the A/D conversion of smoke and temperature mean?

A/D conversion is an analog/digital conversion, which is a program for data processing of the internal circuit of the detector.

16. When the alarm button is pressed, the independent output contact provided by the alarm button can directly control other external devices. What does that mean?

That is, after pressing the button, a switch can be provided, and the device can be directly controlled by connecting the device through this switch.

17, how many wires are connected by hand?

Two without telephone jacks and four with telephone jacks.

18, what is a pump relay? Isn't our hydrant button connected to the water pump? Under normal circumstances, is the water pump started directly by pressing the fire hydrant button?

The pump start relay is used to control the start of the fire pump in the pump control cabinet. According to the specification, the fire hydrant button needs to be directly connected with the fire pump to start the water pump. Press the fire hydrant button, and the fire pump should be started directly.

19, are handwritten newspaper and sound and light all six lines, and two of them are connected by handwritten newspaper and sound and light? Do these two wires have polarity?

Handwritten newspapers usually have four or two wires. Handwritten newspapers generally do not need to be connected by sound and light.

20. What is a diode? 1N58 19 is a serial number?

The description of diode can be found in Baidu Encyclopedia, and the model number is 1N58 19.

2 1, 83 19 Bay's coded modules and non-coded detectors have been eliminated?

The 83 19 coding module and non-coding detector in Gulf have not been eliminated.

22. What equipment do we use to control the live broadcast system? What is the principle of control?

The automatic fire alarm system in Gulf adopts GST-LD-8305 module to control fire broadcasting equipment. The module sends out a fire alarm controller to control the fire broadcasting equipment, and the module performs forced switching after receiving the signal.

23.83 12 is the fire telephone jack the same as the handwritten fire telephone jack? Is the former non-coding device and the latter coding address device? Is it necessary to connect the fire telephone interface, 8 104?

83 12 fire telephone jack is the same as manual fire telephone jack. Both of them can be said to have no code, and the code mentioned here is the code in the fire telephone system. The telephone jack needs to be used with GST-LD-8304 module.
