CH-09-525-Q(HS)

Overview

The CH-09-525-Q(HS) is a piezoelectric chime alarm from the AudioLarm II series, manufactured 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 top-mounted port and wire lead termination. The unit produces a sound pressure level of 70 dB at 5V measured at 61cm. Operating frequencies are centered around 2.9 kHz. The device is rated for an operating temperature range of -20°C to 65°C and holds UL and UR approval agencies. Physical dimensions include a diameter of 35.81mm and a maximum installation height of 37.59mm.

Feature Summary

• Internally driven piezoelectric technology for reliable chime signaling
• Panel mount construction with wire leads for direct integration
• IP68 rating providing dust tight and waterproof protection
• UL and UR agency approvals for industrial safety compliance

Applications

• Industrial machinery status indication
• Equipment fault alarms
• Process control system alerts

Procurement Notes

Verify the specific suffix (HS) against official Floyd Bell documentation to confirm exact acoustic or electrical variations. Ensure the required voltage matches the 5-25V DC specification. Confirm that the IP68 rating meets environmental requirements for the intended installation location. Check for any specific mounting hole dimension constraints based on the 35.81mm diameter.

Selection Notes

Select this component when a durable, waterproof chime is required for harsh environments. The wide voltage range allows flexibility in power supply design. The high ingress protection rating makes it suitable for outdoor or washdown applications. Consider the 70 dB output level relative to ambient noise levels to ensure audibility.

Part Context

This part belongs to the AudioLarm II series, recognized as a widely used industrial alarm line. Floyd Bell specializes in durable audio devices for industrial machines. The CH-09 series typically denotes a standard size piezo chime with panel mount capabilities.

Replacement Considerations

Consult official Floyd Bell substitution guides for verified equivalents. Generic replacements may not match the IP68 rating or UL certification. Verify pinout and voltage compatibility before swapping.
