As the city of tall buildings built up gradually, the elevator has become an indispensable part of People's Daily travel, commercial buildings and shopping malls, the elevator is indispensable, particularly as the elevator five-way intercom and waiting for the elevator elevator five-way calls the rapid development of information auxiliary products, but also greatly promote the rapid development of the industry.




At present, the number of elevators in China has exceeded 6 million! The number is the largest in the world, accounting for one third of the world's population. With the acceleration of domestic urbanization process, the steady progress of affordable housing construction, the construction of commercial buildings and other positive factors, the elevator is increasing at the rate of 15% every year! It can be said that the market prospect of the five party intercom system in China is quite optimistic, and the advantages of the five party intercom system are quite obvious.

1. Simple installation

The five - way intercom system of elevator needs no wiring and installation. Anti-interference and lightning protection, strong signal, one-button call, long communication distance, with a UPS power supply for 48 hours, more clear voice. Facilitate elevator capacity expansion, monitoring room relocation. Low cost (saving cable cost, labor construction cost and maintenance cost).

2. Powerful functions

Elevator five-way intercom system powerful, indoor machine of digital video intercom system is like a small computer, powerful data processing ability and become more powerful networking functions are realized, have very strong dilated and extensibility, can not only realize visible interphone, can also realize multimedia messaging, radio, security alarm, intelligent household, influence function monitoring, etc.

3. Low comprehensive cost

From the point of view of installation, debugging and wiring, using TCP/IP transmission mode, can reduce a lot of investment, plus the construction period is short, save wire and labor costs, and very easy to maintain, therefore, the use of digital visual intercom system, more advantages on the cost.

4. Long transmission distance

At present, the development scale of the community is getting larger and larger. Currently, the digital visual intercom system adopts broadband carrier technology, which can realize low-cost long-distance transmission, and has advantages over optical cable data transmission.


The rapid development of wireless intercom system for elevators also puts forward higher requirements for the industry. Many companies begin to implement intercom system solutions in different ways, with different differences and advantages:

One, wired intercom system

Wire intercom and general telephone wiring, through the telephone line will be the elevator car, elevator room, elevator top, elevator bottom extension connection to achieve communication. Technically easy to do, but the drawbacks are obvious.

1. The overall installation period is 10-15 days.

2. Intercom extension has a service life of about 18-20 years.

3. The intercom extension time is 1 hour, and the intercom host time is 1.5 hours.

4. If the duty room is moved to a farther distance, add additional power supply equipment at the wiring place.

5, some places may have to break the road threading, the cost of actual calculation.

6. The cable adopts 1mm2 multi-strand copper wire.

7. It is recommended to buy two more decoding adapters, two more intercom extension power supply, one more intercom power supply for host, and one more intercom management host for standby.

8. In this way, consideration must be given to whether there is a place for threading (lightning protection).

FM intercom system

The single system of full duplex FM can control up to 72 elevators for intercom call, no wiring is required, reducing the maintenance cost of daily use. Full duplex call, no charge for call, one-time investment for lifetime use, provides a comprehensive intercom call solution for the management center.

1. Call: when the elevator stops in the process of use or is out of power, and other unexpected situations occur, elevator passengers can press the "call" button to issue a call number to the duty room.

2. Features: one-click automatic alarm for passengers, voice recording call, no other operation required; Management center alarm sound, light button, voice prompt call location and warning;

3. Advantages: one-button call, convenient and fast, can effectively solve the intercom call between the monitoring center, machine room, cage, cage top and pit bottom. Without wiring, it saves a lot of expensive line cost. Without wiring, it saves a lot of construction cost of high line laying. It saves a lot of maintenance cost caused by line fault, aging and other factors. Completely eliminate the damage to buildings and roads caused by laying lines; The position of monitoring center can be adjusted as needed without any line adjustment. The whole system construction is very simple, short construction period, quick effect; The wireless range covers a wide range, with strong anti-interference ability and clear sound quality within a radius of 3 km.

3. Wireless intercom can effectively solve the wireless intercom call between the monitoring center and the machine room, which saves a lot of expensive line cost without wiring; Without wiring, it saves the construction cost of high cost of line laying.
