BRP4535S-12-CP

Overview

The Intervox BRP4535S-12-CP is an internally driven piezoelectric audio warning device designed for panel mounting. It operates on a 12 VDC supply with a current draw of 20 mA. The unit generates a sound pressure level of 90 dB measured at a distance of 30 cm. The operating frequency is specified at 2.9 kHz. Physical dimensions include a height of 34.5 mm and a depth of 43.5 mm. The component utilizes screw terminals for connection and features a maximum opening temperature rating of 60 °C.

Feature Summary

• Internally driven piezoelectric construction eliminates the need for external oscillators
• Panel mount design with screw terminal connections for secure installation
• High-output acoustic performance with clear penetrating sound quality

Applications

• Fire alarm systems
• Burglar alarms
• Smoke detectors
• Medical instruments

Procurement Notes

Verify the specific suffix CP against official datasheets to confirm internal circuitry and voltage ratings. Ensure the 12 VDC requirement matches the target system power supply. Confirm that the 90 dB output level meets regulatory noise requirements for the intended environment. Check physical dimensions against enclosure constraints before procurement.

Selection Notes

Select this model when an integrated solution is required without external driving components. The 12 VDC specification suits standard low-voltage control circuits. Consider the 90 dB output for environments requiring moderate audible alerts. Verify that the panel mounting method aligns with the assembly design. Evaluate the 60 °C temperature limit against operational conditions.

Part Context

This component belongs to the Intervox BRP4535 series of piezoelectric alarms. The series includes variants with different voltages such as 24 VDC models. The BRP4535S-12-CP specifically denotes the 12 VDC version with continuous or intermittent tone capabilities. It is manufactured by ICC/Intervox, now part of RKI Instruments.

Replacement Considerations

Cross-reference with other 12 VDC piezo buzzers from the same manufacturer family. Verify pinout compatibility if replacing in existing assemblies. Ensure acoustic output levels are equivalent to maintain safety compliance.
