IDM NT204
The IDM NT204 (DT) Mitsubishi Elevator Digital Five-party Intercom Optical Terminal provides a dedicated digital five-party intercom interface card that matches the signaling of five-party intercom units, enabling five-way communication between the central office and the machine room, car, car top, and pit. The five-party intercom optical terminal is available in 2-channel IDM NT204 (DT), 8-channel IDM ENT448 (DT), 30-channel IDM 30EN (DT), etc., meeting the signal transmission requirements from elevator group machine rooms to the central monitoring room, and also suitable for fiber access transmission in scenarios such as monitoring room relocation or consolidation.
Overview
With the expansion of modern residential communities, the distance between the elevator central monitoring room (main duty room) and the elevator machine room may exceed the transmission distance of five-party intercom twisted pair cables. As a result, the communication mode between the central office and the elevator machine room has undergone various changes. One approach is to use GSM transmission, but this method is constrained by GSM billing models and is not economically efficient.
Beijing Ruiguang Jiyuan Digital Technology Co., Ltd. provides a solution based on fiber optic communication networks to meet user requirements.
Mitsubishi Elevator Digital Five-party Intercom Telephone Optical Terminal Mode
Since the operating principles of digital five-party intercom telephones differ from those of conventional telephones, standard telephone optical terminals cannot be used. Raytrans' dedicated five-party intercom interface card matches the signaling of five-party intercom units, enabling five-way communication between the central office and the machine room, car, car top, and pit.
The five-party intercom optical terminal is available in 2-channel IDM NT204 (DT) elevator intercom optical terminal, 8-channel IDM ENT448 (DT) elevator intercom optical terminal, 30-channel IDM 30EN (DT) elevator intercom optical terminal, etc., meeting the signal transmission requirements from elevator group machine rooms to the central monitoring room, and also suitable for fiber access transmission in scenarios such as monitoring room relocation or consolidation.
An independent Ethernet channel is provided. A dedicated power supply is used to connect to the elevator power source.
