Medical Piezo Buzzers & Audio Indicators

Mallory Sonalert Medical Piezo Buzzers and Audio Indicators are medical devices used in cardiac, ventilators, failure, oxygen levels, and general alarms. These piezo buzzers and audio indicators include SBS, SBT, and MSS series of part numbers. The SBS and SBT modules feature a 150Hz to 4000Hz frequency range and a 9V to 12V wide voltage range. The MSS piezo buzzers and audio indicators offer a 4.5V to 5.5V wide voltage range. Mallory Sonalert Medical Piezo Buzzers and Audio Indicators are used in medical applications and machines. The devices come with cUL approval to IEC60601-1-8. Typical applications include apnea, blood heating, call stations, CPAP, defibrillators, dialysis, and handheld meters to high-reliability infant monitors.
