Overview
The BRP4549S-110-C is an AC piezoelectric buzzer designed for audio warning applications. It operates within a voltage range of 30 to 120 VAC and draws a maximum current of 20 mA. The device produces a sound pressure level of 90 dB at a distance of 30 cm, with a resonant frequency of 2900 ± 500 Hz. It features panel mount screw terminals and functions in continuous or intermittent modes with a 1:1 duty cycle. The unit is rated for operation between -20°C and +80°C.
Feature Summary
- Piezoelectric acoustic generation for clear penetrating sound quality
- Panel mount installation using screw lugs
- Compatible with continuous or intermittent operational modes
Applications
- Fire alarm systems
- Burglar alarms
- Smoke detectors
- Medical equipment alerts
Procurement Notes
Verify the specific part number suffix to ensure correct voltage and acoustic specifications. Confirm RoHS compliance status if required by project standards. Check datasheet for exact mounting dimensions and terminal configuration before integration. Ensure operating temperature ranges align with the intended environment.
Selection Notes
Select this component when high-volume audible alerts are required in industrial or safety-critical environments. The wide AC input range allows flexibility in power supply design. Consider the 90 dB output level relative to ambient noise conditions. Verify that the screw lug termination method suits the available PCB or panel space.
Part Context
This model belongs to the ICC Intervox BRP4549S series of AC buzzers. The series includes variants with different voltage ratings and acoustic outputs, such as the BRP4549S-24-CD and BRP4549S-110-CP. These devices are engineered for reliable performance in warning signal applications requiring robust construction and consistent acoustic output.
Replacement Considerations
The BRP4549S-110-CP is a related variant within the same series but offers a lower current draw of 10 mA and reduced sound pressure level of 80 dB. Substitution requires verification of acoustic requirements and electrical compatibility.
