IDM NT202 (DT) Mitsubishi Elevator Digital Five-party Intercom Optical Terminal
The IDM NT202 (DT) Mitsubishi Elevator Digital Five-party Intercom Optical Terminal provides a dedicated digital five-party intercom interface card that matches the signaling of the five-party intercom, enabling five-party communication between the central office and the machine room, car, car top, and pit. Five-party intercom optical terminals include the 2-channel IDM NT202 (DT), 8-channel IDM ENT448 (DT), 30-channel IDM 30EN (DT), etc. They meet the signal transmission needs from elevator group machine rooms of different capacities to the central office monitoring room, and are also suitable for fiber access transmission when monitoring rooms are relocated or merged.
Overview
With the expansion of modern residential communities, the distance between the elevator central office monitoring room host duty room and the elevator machine room may exceed the transmission distance of the five-party intercom twisted pair. Therefore, the communication mode between the central office and the elevator machine room has also changed in many aspects. One method is to use GSM transmission, but this method is subject to GSM charging models and is not very economical or reasonable.
Beijing Raytrans Digital Technology Co., Ltd. provides a solution based on fiber optic communication networks to meet user needs.
Mitsubishi Elevator Digital Five-party Intercom Telephone Optical Terminal Mode
Because the working principle of digital five-party intercom telephones differs from that of regular telephones, ordinary Telephone Optical Terminals cannot be used. Raytrans's dedicated five-party intercom interface card can match the signaling of the five-party intercom, enabling five-party communication between the central office and the machine room, car, car top, and pit.
Five-party intercom optical terminals include the 2-channel IDM NT202 (DT) elevator intercom optical terminal, 8-channel IDM ENT448 (DT) elevator intercom optical terminal, 30-channel IDM 30EN (DT) elevator intercom optical terminal, etc. They meet the signal transmission needs from elevator group machine rooms of different capacities to the central office monitoring room, and are also suitable for fiber access transmission when monitoring rooms are relocated or merged.
Provides an independent Ethernet channel. Uses a dedicated power supply connected to the elevator power supply.
