CH-09-525-S(F)

Overview

The CH-09-525-S(F) is a panel mount piezoelectric chime alarm from the AudioLarm II series by Floyd Bell Inc. It operates on a DC voltage range of 5 to 25 volts with an internally driven indicator circuit. The device produces a sound pressure level of 70 dB at 5V measured at 61cm and functions at a frequency of 2.9 kHz. Power consumption ranges from 5 to 25 mA. It features wire leads for termination, top port positioning, and an IP68 rating for dust tightness and waterproofing. Physical dimensions include a 35.81 mm diameter and a maximum installation height of 37.59 mm.

Feature Summary

• Piezoelectric technology providing durable industrial audio signaling
• IP68 rated enclosure ensuring protection against dust and water ingress
• Internally driven indicator circuit for simplified integration
• Panel mount design with wire lead termination

Applications

• Industrial machinery status indication
• Control panel alarm systems
• Equipment monitoring in wet or dusty environments

Procurement Notes

Verify the specific suffix (S vs W) against official datasheets to confirm acoustic output characteristics, as variations may exist within the same base model number. Confirm that the wire lead configuration matches the intended connection method. Ensure the operating voltage aligns with the 5-25V DC specification provided in the component documentation.

Selection Notes

Select this component when high environmental protection is required due to its IP68 rating. The wide voltage input range allows flexibility in power supply design. Verify that the 70 dB SPL meets the ambient noise requirements of the installation site. Consider the physical dimensions to ensure compatibility with the available panel cutout space.
