Mallory IEC60601-1-8 Medical Alarms

Extended choice of medical-qualified sounders including new 100dB loudspeaker

Mallory Sound Products has introduced new and louder IEC60601-1-8 medical alarms, extending its line of IEC60601-1-8 qualified medical sounders and compact transducers, which offer power savings in battery-powered and portable medical equipment.

Mallory’s medical alarms are recognized by UL and CUL for compliance with all the requirements of the IEC60601-1-8 standard. These medical alarms may easily be integrated into medical electronics system designs.

For medical applications requiring a high sound level such as in operating theaters, Mallory’s 45mm-diameter SBS series speaker models are ideal: they produce 100dB at a distance of 0.1m from the speaker, and operate from a voltage between 9V and 12V. They are available with or without circuitry.
