When visual signals are insufficient, acoustic signals provide critical alerts through pure tones, specific frequencies, or spoken messages. These are categorized by urgency and should be designed to be distinguishable from ambient factory noise. IEC 60073:2002

Correctly selecting pilot lights, illuminated pushbuttons, and emergency stop switches.

Standardization ensures that operators can rapidly recognize conditions and actuator positions across different systems. iTeh Standards Visual Indicators (Color Coding): Emergency, Danger, or Fault (e.g., DC supply failure). 🟡 Amber/Yellow: Abnormal condition or Warning. 🟢 Green: Safe, Normal, or "Go" (indicates the system is ready). 🔵 Blue: Mandatory action (e.g., "reset required"). ⚪ White: General information or auxiliary status. Flashing Rates: Standardizes attention-grabbing signals. Normal Flashing: 1.4 Hz to 2.8 Hz (used for immediate attention). Slow Flashing:
