Overview
The SBT5VHCSPPC is a medical-grade audio indicator manufactured by Mallory Sonalert Products Inc. It is designed to comply with IEC 60601-1-8 standards for audible signals in healthcare environments. The device operates on a DC voltage range of 3.3 to 5 volts and produces a sound pressure level of 90 dB. It features a specific cardiac alarm tone configuration suitable for critical care applications. The unit is supplied in a bulk pack format and includes RoHS compliance certification.
Feature Summary
- Complies with IEC 60601-1-8 AMD1 standards for medical audible signals
- Generates a dedicated cardiac alarm tone pattern
- Operates within a low voltage DC range of 3.3 to 5 volts
- Provides high-intensity acoustic output at 90 dB
Applications
- Medical patient monitoring systems
- Critical care alarm panels
- Hospital diagnostic equipment
- Healthcare safety signaling devices
Procurement Notes
Verify the specific suffix 'PPC' against the official Mallory Sonalert datasheet to confirm the exact packaging and tone configuration. Ensure the component meets the required IEC 60601-1-8 AMD1 revision for your target medical device certification. Confirm availability through authorized distributors as stock levels may vary.
Selection Notes
Select this model when a standardized cardiac alarm tone is required for IEC 60601-1-8 compliant designs. The 3.3-5VDC input makes it suitable for low-voltage digital logic interfaces common in modern medical electronics. Consider the 90dB output level relative to the enclosure acoustics and ambient noise requirements of the final application.
Part Context
This component belongs to the SBT5 series of industrial and medical audio indicators from Mallory Sonalert. The series is known for providing pre-programmed, recognizable alarm tones that meet international regulatory standards. The SBT5VHCSPPC variant specifically addresses the need for distinct cardiac alerts in sensitive healthcare environments.
Replacement Considerations
Check for other SBT5 variants with different suffixes if alternative tones or voltage ranges are needed. Verify mechanical compatibility if replacing existing units, as panel cutout dimensions may vary across the SBT5 family.
