PUI Audio IEC 60601-1-8 Medical Audio Indicators

PUI Audio IEC 60601-1-8 Medical Audio Indicators regulate alarm signals in medical environments where multiple instruments simultaneously create audible alarms in the same room. These piezoelectric audio indicators feature a 3.3VDC to 5VDC operating voltage range, 20mA active current, 12mA standby current, and a frequency range of 150Hz to 4000Hz. The IEC 60601-1-8 audio indicators replaced the priority/note system with auditory icons and auditory pointers. The auditory icons utilize everyday sounds to enhance recognition and localization, and the auditory pointers identify the device and alarm priority. These audio indicators include three priority levels (low, medium, and high) to convey the appropriate urgency when the alarm is triggered. Typical applications include general, cardiovascular, oxygenation, and ventilation alarms.

The IEC 60601-1-8 medical audio indicators come in an ABS (black) housing material with a thru-hole/pins terminal type. These indicators are RoHS and REACH compliant.

Features

  • Based on piezoelectric
  • ABS (black) housing material
  • Thru-hole/pins terminal type
  • Hand solder and wave solder are acceptable soldering methods
  • IEC 60601-1-8 compliant
  • RoHS/REACH environmental compliances
  • Auditory icon:
    • 200Hz to 5000Hz alarm frequency range
    • Use frequencies below 1000Hz for long-distance availability
    • Frequencies below 500Hz for audibility through obstacles/partitions
    • Avoid overlap with intense background noise by selecting distinct frequency bands
  • Auditory pointer:
    • 150Hz to 1000Hz includes one key frequency among the top five sound levels
    • Ensure five harmonics in the 150Hz to 4000Hz range
    • Optimize rise time to avoid distortion and fall time to prevent pulse overlap
    • Pulse durations:
      • 25ms to 75ms high
      • 90ms to 200ms medium
      • 400ms to 600ms low
