Introducing Mallory’s MSW Series of IEC 60601-1-8 Medical Alarms which use the IEC Supplied Melody Sound Files

April 1, 2023

IEC 60601-1-8 AM2 (2020) is the latest IEC specification that covers the use of audible alarms in medical equipment. Annex G of IEC 60601-1-8 AM2 (2020) adds the ability to produce melody tones by using IEC supplied sound files.

Mallory’s new MSW series uses these IEC sound files, and is approved by UL to meet IEC 60601-1-8 AM2 (2020) Annex G.

The MSW series uses the same PC pin layout, and electronic control of the current popular MSS series (23 x 13 mm). So, if a medical application is already using a 2 PC pin or 5 PC pin MSS model, the equivalent MSW model will drop right in. For example, model MSS5C (three cardiac priority tones) can directly be replaced by model MSW5C (three cardiac priority tones using IEC sound files).

Like the MSS Series, the MSW series offers several different medical priority tone options such as 1 priority tone, all 3 priority tones, and models with 1 or 2 priority tones and a 2500 Hz non-medical tone which can be used for other audible indication needs.

Mallory 100% tests every medical alarm to verify qualification to IEC 60601-1-8, checks the sound level & current values, records the sounds generated by the alarm, and ties all this saved data to the serial number listed on the alarm label.

Based on the popularity of current MSS models, Mallory expects the following MSW models to be popular also, and these models will soon be in distributor stock ready for prototyping:
