Audible Alarms

110 dB at 10 Feet PLC Compatible 55 Tone Capability NEMA Type 3R UL; cUL; CE Approvals The Edwards 5530M Adaptatone Millennium is a heavy duty industrial tone selectable signaling device capable of producing volume controlled high decibel tones. It uses a microprocessor circuit to create 27 distinctive tones selected by setting a dip switch within the unit. The Adaptatone Millennium can be activated from field wired normally open contacts or from a 24 VDC external voltage source such as an output of a PLC. PLC compatibility assures no additional loading resistors or relays are required to ...
