Elevator five party talk with a few heart wires, how about a wiring way Thank you

There are two ways:

1. Bus system: use a 4-core shielded wire.

by the fire control room.

The five-party intercom host lead is connected in series to the elevator control cabinet of each elevator machine room, and there is a five-party intercom interface in the control cabinet.

2. Split line system: with 2 cores, 3 cores and 4 cores of shielded wires, the intercom host is wired to the elevator control cabinet of each elevator machine room.

Elevator five-party call wiring requirements:

1. Wiring principle: the bus mode is used for wiring, and the multi-way bus mode can be used according to the principle of the shortest total length of wiring.

2. The total length of a single bus wiring cannot exceed 3000 meters. In the case of more than 3000 meters, the splitter can be divided into up to 8 buses, and the corresponding line length of each port cannot exceed 3000 meters (including the total length of all branch lines).

3. Cable specifications.

3 cores of ordinary RVV cables are used, and a certain amount of spare wires (3 for each route is recommended) needs to be considered

Cable Requirements:

Number of cores: more than 3 cores.

1. Cross-sectional area of each core: not less than.

2. Conductor resistance: not greater than.

3. Rated voltage.

Not less than 100V

4. Withstand voltage (AC): 500V min

5. Insulation resistance.

20℃min）：80moch/km

6. Continuous use temperature range: -5 to +70

7. Electrostatic capacitance:

There are several ways to wiring the elevator five-party intercom:

1. Bus system, with a 4-core shielded wire, is connected in series to the elevator control cabinet of each elevator machine room by the five-party intercom host lead of the fire control room, and there is a five-party intercom interface in the control cabinet.

2. Split line system: with 2 cores, 3 cores and 4 cores of shielded wires, the intercom host is wired to the elevator control cabinet of each elevator machine room.

Specifically, it is necessary to consult what brand of ladder is used, what brand of five-party intercom equipment is equipped, and what kind of system is used in the equipment. Then consider design and routing.

Look at what kind of elevator manufacturer is equipped with, generally six cores are enough, but there are also eight cores, four cores, wiring anyway from the elevator machine room to the property planting room, there are also from the elevator pit to the planting room.

It's best to ask the manufacturer you made, more precisely.

RVV cable is used.

or BVR wire, 4 cores, two pairs twisted, preferably shielded.

The elevator five-party call is the call between the five parties in the elevator intercom system: the main host of the management center, the elevator car, the extension of the elevator machine room, the top of the elevator and the bottom of the elevator shaft.

The wire requirements of the five-party intercom are different according to the products of various manufacturers. Most of the common ones on the market are RVVP (shielded cables.

Wire rod, wire diameter and wire rod, wire core requirements are also different, the general wire diameter is more, the number of cores is mostly two cores, three cores and four cores. The specific wire diameter and number of cores are determined according to the manufacturer's requirements.

Elevator five-party intercom is generally commonly used is the four-core bus system.

Generally, the commonly used is the four-core bus system, and it is best to use RVVP4* wire. Five-party calls are mainly distributed in the following areas: computer room, maintenance box, pit box, car, main control room, can start from the electric control box in the computer room, and lead to each area respectively.

The operation process of the five-party intercom:

1. After receiving the elevator call, the elevator five-party intercom system control machine will call the elevator corresponding to the warning yellow light flashing, and first send out an alarm sound prompt, and then hear the recording call of the elevator intercom ** extension, after that, the central control machine automatically obtains the dominant control of the elevator intercom.

2. After the central control machine obtains the dominant control of the intercom, press and hold the intercom button with the signal light on, when the working light is red light, at this time, speak to the microphone of the central control machine, the elevator will hear your speech sound, release the button to automatically receive the elevator 5 seconds back.

3. The elevator five-party intercom system does not need to perform any operation in the elevator, and can speak directly to the speaker.

4. When the call button is pressed in the elevator, the elevator five-party intercom system will slide to the recorded call content in the elevator from the year, and the recorded call content will be transmitted to the central control machine wirelessly. <>

Elevator five-party call refers to the elevator intercom system between the management center host, the elevator car, the elevator machine room extension, the top of the elevator, the bottom of the elevator shaft between the five parties.

The function of the elevator emergency alarm device is that when the elevator has a trapped person failure, the trapped person can simply and quickly use the device to get in touch with the outside world. This is especially important when you don't have a mobile phone or if you don't have a signal.

Elevator five-party function

Elevator five-party intercom is a kind of intercom dedicated to the elevator car, elevator control room, and management center. It can realize three-party or even five-party calls, which belongs to a series in the security intercom industry. Its functions are as follows:

1. By adding an elevator walkie-talkie, the monitoring center or the duty room, the machine room, the car, the car top, and the bottom of the pit can be used to make multi-party calls.

2. One-to-one call can be realized through the management of the switch after the elevator actively calls the host.

3. The engineering interface is complete.

4. If the central control machine takes the initiative to talk, the multiple elevators managed by the switch will receive it at the same time, and all the words in the multiple elevators will be transmitted back to the center console.

5. When an elevator fails, after calling the central control machine, the fault elevator indication obtained by the central control machine is all the elevators managed by the switch, and it cannot be accurate to which elevator fails, but the location of the faulty elevator can be confirmed with the personnel in the car through one-to-one intercom.

Intercom. Generally, there are four wires, which are positive, negative, r, l, and the device connection line is yellow, green, red, and black, according to the corresponding color, the wireless extension transmitter.

Connect with the cable of the computer room**.

The yellow-green line of the machine room** is connected with the yellow-green line of the accompanying backup cable in the elevator control cabinet; The yellow and green lines in the accompanying spare cable connect the roof intercom, the pit intercom and the car intercom. The other two orange wires of the car intercom are connected to the elevator signal line.

The elevator on our side is replaced by a network cable, and it is best to use a multi-core soft ** cable (similar to the connection core of the earpiece of the landline and the host), 2-3 circuits. The car and the car roof can be used in the same circuit. For details, please consult the local quality inspection bureau.

1. Generally, elevator manufacturers require 4* communication cables.

2. In order to meet the needs of scalability, it is generally possible to lay 5 types of network cables.

3. It is still necessary to communicate with the elevator manufacturer.

4. Due to the pure differences between elevator manufacturers and each product, and the on-site situation is also varied, I suggest that it is still based on the actual situation, and the use of network cable is a more common method under the current conditions.

Walkie-talkies are generally four wires, which are positive, negative, r, and l. The power supply is placed on the top of the car, the host is in the machine room, and the intercom of the car and the car top intercom and the power supply are connected by the accompanying cable, and the host of the machine room is then wired to the pit intercom through the hoistway cable. The intercom in the duty room can be wired from the shaft intercom.

The wiring of the elevator five-way call needs to find the elevator's accompanying backup cable, and the original signal line cannot be used.

The equipment connection cable is yellow, green, red and black, and the cable of the wireless extension transmitter and the computer room is connected together according to the corresponding color; The yellow-green line of the machine room** is connected with the yellow-green line of the accompanying backup cable in the elevator control cabinet; The yellow and green lines in the accompanying spare cable connect the roof intercom, the pit intercom and the car intercom. The other two orange wires of the car intercom are connected to the elevator signal line.

Elevators"Five-party intercom"Also called"Five-way calls"The function refers to the mutual communication between the car, the car roof, the machine room, the pit and the building monitoring room.

The general user is only responsible for the cable from the elevator machine room to the monitoring room of the building, and other cables are provided by the elevator manufacturer (some are integrated in the accompanying cable), and the cable from the elevator machine room to the monitoring room of the building is generally used on the line, as for the use of a few cores of cable, it depends on the number of elevators in parallel (or single control, group space), and different brands will be different, it is best to let the elevator manufacturer put forward requirements, and then let the building weak current project to buy cables and lay cables, generally at least 6 cores or more.

Elevator five-party intercom system elevator five-party intercom system wiring diagram: its single system can control up to 72 elevators for intercom calls, no wiring, reduce the maintenance cost of daily use, call full duplex, call does not need to cost, one-time investment for life, for the management center to provide a comprehensive intercom call solution.

Call: When the elevator is in the process of use, there is an unexpected situation such as a malfunction, shutdown or power outage, and the elevator passengers can press the "Call Zheng Qiaotan" button to send a call signal to the duty room. Features:
