The AMETEK NOVATONE NT2-12D Horn delivers 88 dB at 10 ft and provides 16 field‑selectable tones, giving a compact, configurable audible device for process control and annunciator systems. The NT2 family includes four voltage variants—NT2-12D (12 VDC), NT2-24D (24 VDC), NT2-120A (120 VAC), and NT2-230A (230 VAC)—with a user‑adjustable volume and the option for flush‑panel or wall mounting, and it is suitable for use in NEMA 4 and 4X environments. Commonly used as the audible component of AMETEK annunciators, it can be triggered by control outputs from DCS/PLC/SCADA systems or other equipment, enabling distinct tones to identify specific alarms across multiple lines.
