Edwards Signals ED-5540M120N Adaptatone Tone Generator
The Edwards 5540M Millennium Central Tone Generator has been designed for applications where simultaneous signaling of a high decibel, heavy duty signal is required. The tone generator assures a synchronous signaling sound from all remote speakers. The Millennium Central Tone Generator produces the 27 standard Adaptatone sounds. Four tones may be activated from field-wired, normally open contacts, or a 24VDC or 120VAC external voltage source such as an output of a PLC.
