The Edwards 5531MHV Series Adaptatone Millennium is a high volume, 30 watt heavy-duty industrial signaling device capable of producing volume-controlled, high-decibel tones. Four tones can be activated from field-wired, normally open contacts, or a 24VDC or 120VAC external voltage source such as the output of a PLC. Normally open contacts can be obtained from the Cat. No. 5538-4 and/or Cat. No. 5538-4R Adaptatone Signal Actuators.

The unit uses a microprocessor circuit to create 55 distinctive tones, selected by setting miniature dip switches within the unit. The tones programmed operate on a pyramid-type priority system in which a switch with a programmed tone takes priority over all switches that follow it. For more information on priority tone operation and a complete listing of all 55 tones, refer to catalog pages on the left hand side of this page.

Designed for industrial applications including emergency warning systems, plant evacuation and security intrusion alarms, process monitoring, shift start-and-dismissal horns, and paging signals.

The 5531M is designed for either 1/2" (13mm) conduit or surface mounting. See Adaptatone Signaling Installation under Catalog Pages on the left hand side of this page.
