PUIAUDIO.COM NEW PRODUCT ANNOUNCEMENT Medical Audio Indicators Nov 2024 IEC 60601-1-8 Compliant
PUIAUDIO.COM Engineers who design products for medical applications often face the difficult task of creating auditory alarm signals which comply with the International Electrotechnical Commission’s regulatory standards. The IEC 60601-1- 8 standard regulates alarm signals that might be heard in a medical environment, specifically in cases where multiple instruments might be creating audible alarms in the same room simultaneously. Traditionally, IEC 60601-1-8 compliant medical equipment requires an engineer to approach audio compliance from two aspects. Careful selection of an audio output device (one capable of reproducing the stipulated alarm frequencies for compliance) is required, in addition designing a compliant audio signal to create the alarm. With ever -increasing quantities of medical equipment found both inside and outside of clinical environments, PUI Audio understands our customers’ needs for a reliable, easy -to-use component. We set out to give engineers the ability to quickly and effectively certify their devices for IEC 60601-1-8 compliance - and now are introducing the latest expansion of our Audio Indicators - Medical Indicators. Whether the application calls for a general medical alarm, a cardiovascular alarm, oxygen alarm, or even ventilation alarms – PUI Audio’s Medical Indicators can help achieve IEC 60601 -1-8 compliance.
PUIAUDIO.COM These piezoelectric-based audio devices produce an IEC 60601-1- 8 compliant alarm tone when a DC voltage is applied. Three priority levels are present in the device , in addition to the base tones, to ensure the appropriate urgency can be conveyed when the alarm is triggered. Control of the device could not be easier – simply connect to a DC power supply, and select whether or not a Low, Medium, or High priority tone should be played by grounding the corresponding control pin!
