Explosion-proof Multi-Tone Audible Signal

Description

The Edwards 5531MV Adaptatone Millennium voice unit is a heavy-duty industrial, tone-selectable, signaling device capable of producing volume-controlled, high-decibel tones and up to 20 seconds of field recorded voice messages. The Adaptatone Millennium voice unit can be activated from field-wired, normally open contacts, or a 24 VDC or 120 VAC external voltage source such as an 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 and store 20 seconds of field recorded voice messages. Messages and tones may be selected by setting miniature dip switches within the unit. A total of four messages and tones programmed operate on a pyramid-type priority system. For more information on priority tone operation and a complete listing of all 55 tones, see the catalog pages listed on the left hand side of this page. The 5531MV is designed for either 1/2 in. (13mm) conduit or surface mounting. See Adaptatone Signaling Installation in the catalog pages on the left hand side of this page.
