Precautions For Connecting Power Supply Cables Of Explosion-proof Industrial Loudspeaker Intercom Systems

For centralized power supply mode, the power supply of the telephone station should be fully taken into account.
For systems with a large number of voice stations and high amplification power, it is recommended to adopt local power supply mode.
For a 25W loudspeaker station, each power supply cable can only connect to 60 stations.
For a 50W loudspeaker station, each power supply cable can be connected to 40 stations.
Depending on the number of substations and the magnitude of the amplification power, multiple power supply cables need to be connected from the cable junction box.
In principle, there should be no connection points in the middle of the power cord. If there are any, a junction box must be added.
