Overview
The CH-09-201-W(M) is a piezoelectric chime alarm from the AudioLarm II series by Floyd Bell Inc. It features an internally driven indicator circuit and accepts DC input within a voltage range of 5 to 25 volts. The device operates at a frequency of 2.9 kHz with a sound pressure level of 70 dB measured at 5 volts and 61 cm distance. Power consumption ranges from 5 to 25 mA depending on the applied voltage. Designed for panel mounting, it utilizes wire leads for termination and offers IP68 protection against dust and water ingress. The unit measures 1.410 inches in diameter and has a maximum installed height of 1.480 inches.
Feature Summary
- Internally driven indicator circuit simplifies integration
- Piezoelectric technology ensures durable operation
- IP68 rated for dust tight and waterproof environments
Applications
- Industrial machinery status indication
- Panel mount alarm systems
- Equipment requiring watertight audio alerts
Procurement Notes
Verify the specific suffix (M) against official datasheets to confirm lead wire length and termination style. Confirm UL/UR approval requirements match your regional safety standards. Ensure the operating voltage falls strictly within the 5V to 25V DC range to maintain specified acoustic performance and prevent component damage.
Selection Notes
Select this model when a compact, internally driven chime is required for harsh environments. The IP68 rating makes it suitable for washdown areas or outdoor enclosures. Compare the 70 dB SPL output against ambient noise levels to ensure audibility. Verify that the 2.9 kHz tone matches the desired alert characteristic for your application.
Part Context
This component belongs to the AudioLarm II series, widely recognized in industrial settings. It serves as a reliable audible notification device for control panels. The design prioritizes durability and ease of installation through standard wire lead connections.
Replacement Considerations
Check manufacturer documentation for direct cross-references. Ensure any substitute maintains the same voltage range, mounting dimensions, and IP68 rating. Verify compatibility with existing driver circuits if the replacement lacks internal drive capabilities.
