The Edwards 5541M Millennium System Master is a fully supervised personnel notification control system for both emergency facility evacuation, and non-emergency process control and plantwide signaling communications.

The System Master may be used for ancilliary Fire Alarm evacuation by tying into an existing fire alarm system.

The 5532M Series Speaker/Amplifier is used for sound output. Up to 200 speaker/amplifiers can be connected to the system master.

The System Master is simple to program and operate using a nine-button keypad and an easy-to-read, 40-character LCD display, with Dynamic Zone Control (DZC). DZC enables zone reconfiguration through a series of simple keystrokes without the need for expensive system rewiring.

Employing both voice and tone to alert, warn and communicate, the System master features 27 built-in tones, hand-held microphone operation, and stores up to four, five-second, field-recordable voice messages for playing over remote speakers. PBX phone paging is included, so no separate telephone paging system is required. The Millennium System Master meets all OSHA self-monitoring, prioritization and standby power requirements, plus the latest UL standards for evacuation signaling.
