Supervised Voice Evacuation System

Eaton’s Autonomous Control Unit (ACU-8421), part of the ALERiTY integrated MNS platform, is a supervised, multi-use, In-Building Emergency Communications System, which provides paging, background music, messaging, and emergency voice communications with 24 VDC battery backup.

The Individual Building System provides full control of building notification appliances such as loudspeakers and strobe lights. The ACU-8411 includes a SAFEPATH (SP40S); IP Communicator (IPC-8020), an Ethernet communication network device; interface; and cable. The ACU-8421 can be controlled and monitored through the WAVES over IP (WoIP) Integrated Base Station, which can send messages to one ACU-8421 or multiple ACUs. Eaton-approved radios can be added to provide wireless communications, operating in either a 5.8 GHz frequency band (RADIO-500G) or 900 MHz ISM band (RADIO-900M). 

  • Integrates with WAVES over IP MNS for site-wide communications; wired and wireless IP network options available
  • Integrates with fire alarm systems
  • Continuous self-monitoring - BIT (Built-In Test) information from the WAVES ACU is transmitted to the WAVES Integrated Base Station (IBS)
  • Live Microphone override
  • 8 Digital Recorded Messages (Stored locally); Unlimited messages from the IBS
