Medical Alarms

Mallory’s IEC 60601-1-8 Medical Alarm models have been approved at UL & CUL to meet the requirements of IEC 60601-1-8. These models have circuitry, only require DC voltage, and they can produce the low, medium, and high priority tones needed to meet IEC 60601-1-8. Mallory’s smallest models are in the MSS Series which produce 90 dB @ 10cm in a compact 23 x 14mm housing with PC Pins. Mallory’s SBT Series utilizes a piezo transducer in a 45 x 14mm housing, and are ideal for low current applications such as when a supercapacitor is used to provide a short-term power failure alarm. Mallory’s SBS Series utilizes a larger speaker in a 45 x 15mm housing which enables a sound level of 100 dB @ 10 cm and are appropriate for louder environments such as an operating room.

Mallory’s Medical Piezo Transducer models do not have any circuitry, but the user only needs to apply a single 200 Hz square wave signal, and the fundamental frequency and harmonics are produced acoustically. The user still needs to turn the signal on and off at the appropriate rate to meet the timing requirements listed in IEC 60601-1-8. Since these models utilize a piezo transducer, current levels are extremely low, and sound levels are typically 90 dB @ 10cm in a 45 x 14mm housing.

Mallory’s Medical Speaker models do not have any circuitry, but the user only needs to apply a single 325 Hz square wave signal, and the fundamental frequency and harmonics are produced acoustically. The MSS speaker models produce 90 dB @ 10 cm in a 23 x 14mm housing, and the SBS speaker models produce 100 dB @ 10 cm in a 45 x 14mm housing.

Medical models are available in the MSS Series, the SBT Series, and the SBS Series which produce 1 medical priority tone, 3 medical priority tones, or 2 medical priority tones & a standard 2500 Hz non-medical tone that can be used for other sound indication needs in the application.
