AdaptaTone Millennium Multiple-Tone Signal w/ Single Output, 24 VDC/120 VAC

Heavy-duty, tone-selectable signaling devices are capable of producing volume-controlled, high-decibel tones. They use microprocessor circuits to create 55 distinctive tones (selected by setting an internal dip switch). And they can be activated from field-wired, normally open contacts or from 24 VDC or 120 VAC external voltage sources. They're also PLC compatible, assuring no additional loading resistors or relays are required to set them up. Other features include speakers that can be rotated and locked in any horizontal direction. Units produce 110 dB at 10'. NEMA Type 3R (5531M Series is also IP44 rated). UL listed for Class I, Div. 2, Groups A, B, C and D; Class II, Div. 2, Groups F and G; Class III hazardous locations. Gray.
