Overview
The CH-09-201-S(M) is a piezoelectric chime alarm from the AudioLarm II series by Floyd Bell Inc. Designed for panel mounting, this internally driven indicator operates on a DC voltage range of 5 to 25 volts. It features a sound pressure level of 70 dB at 5V measured at 61cm and generates a frequency of 2.9 kHz. The unit draws between 5 and 25 mA of current and is rated for an operating temperature range of -20°C to 65°C. It carries UL and UR approval agencies and meets IP68 standards for dust tightness and waterproofing. Physical dimensions include a 1.410-inch diameter and a maximum installation height of 1.480 inches.
Feature Summary
- Internally driven piezoelectric technology for simplified circuit integration
- IP68 rated enclosure providing dust tight and waterproof protection
- Panel mount design with top ported wire leads for secure installation
Applications
- Industrial machinery status indication
- Control panel chime signaling
- Equipment alarm systems requiring environmental resistance
Procurement Notes
Verify the specific suffix (M) against official datasheets to confirm termination type and lead configuration. Ensure the required voltage matches the 5-25V DC input range. Confirm that the 70dB SPL at 61cm meets acoustic requirements for the intended application environment. Check for UL/UR listing compliance if required by local safety regulations.
Selection Notes
Select this component when a durable, environmentally sealed chime is needed for panel mounting. The wide voltage range allows flexibility in power supply design. Consider the IP68 rating for applications exposed to moisture or dust. Verify that the 2.9kHz frequency is appropriate for the desired audible alert tone.
Part Context
This part belongs to the AudioLarm II series, a widely used industrial alarm line known for durability. It serves as a reliable indicator for various industrial machines where standard buzzers may fail due to environmental conditions. The series emphasizes robust construction and consistent performance across varying temperatures.
Replacement Considerations
Consult official Floyd Bell documentation for direct cross-references. Generic replacements may not match the IP68 rating or specific acoustic profile. Verify pinout and voltage compatibility before substituting.
