Characteristics of GL900 building visual intercom system products

Summary.
This system use cable TV transmission technology, video, audio, data signal modulation in the high frequency carrier wave, at the same time line feed,
No need for additional power line. The whole system from the corridor to the district network by a SYWV75-5 RF cable (cable TV special line) completed,
The extension service wire requires only a RVV general 2 wire non-polar access. The whole system has simple wiring, equipment are connected by adaptive design,
Free debugging realization of engineering.
Main features:
A unit of product:
1 each floor user distributor using standard RF F head into a cascade form.
2 user distributor to extension using RVV two core line of the non polarity connection, 10 meters, 10-20 meters used by 0.3mm ²
3 0.5mm, 20-30 meters with 0.75mm ² ². Each user interface has short circuit protection, short-circuit the system does not affect the normal use.
Each of the 4 power supply box for 32 households, a 36V feed, reduce line losses. The corridor supply power box built-in adaptive amplification circuit,
5 no need for additional amplifier.
6 for a multi family (more than 8) can be used to expand the floor branch form, flexible and convenient.
7 the number of each unit host through the Host dispenser can be expanded to 100.
Each of the 8 unit is the maximum capacity of 1000 households.
Two, network system:
1 each unit with a network switch, the host power supply box through a cable feed.
Between 2 different network switch using standard RF F head into a cascade form.
3 of the whole system construction method with cable TV engineering, according to the actual distribution of each unit is divided into a plurality of branch together to total trunk,
To achieve convenient, fast, the province line objective.
4 main discharger is added by a standard RF F head and out of the way and adjustment free.
Need not to switch between the 5 units total trunk, wall machine, machine, only small exchanger to realize connection, save the exchange cost.
5 system network distance of 1.5 km.
6 network system the maximum capacity of 30000 households.
GL900D single user visual intercom product characteristics
1 the use of balanced transmission technology, all the wiring for the RVV two core non polarity connection. 10 meters, 10-20 meters used by 0.3mm ²
2 0.5mm ², with 0.75mm ² 20-30 meters, 30 meters above the 1.0mm ², the longest transmission distance of 50 meters.
3 the maximum capacity of 2 drag 4 (2 door machine drag 4 extensions)
4 the machine adopts a series connection type, 2 door machine through the distributor extension.
5 of the entire system consists of a 18V/2A power adapter power supply, power supply from the doorway machine or extension of access, flexible and convenient.
