The 5400ACS is an integrated announcement controller with built-in message server capability that is the core of an EN54-16 compliance life/safety emergency notification system. These units contain all of the intelligence to manage an entire system of emergency communication stations, digital zone manager amplifier units, and other network peripherals. The 5400ACS manages the system in compliance with the EN54-16 standard, performing overall supervision and reporting of equipment faults plus any ongoing alarm conditions. The 5400ACS is capable of interfacing with GLOBALCOM 1100ACS/1200ACS units when additional non-emergency features or additional peripherals are required in an installation.
