CH-V09-525-S(M)

Overview

The CH-V09-525-S(M) is a panel mount chime alarm manufactured by Floyd Bell Inc. It belongs to the Audiolarm II series and utilizes piezo technology for sound generation. The device features an internally driven indicator circuit and accepts DC input within a voltage range of 5 to 25 volts. It 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. The unit is rated IP68, providing dust-tight and waterproof protection. Operating temperatures span from -20°C to 65°C. Physical dimensions include a diameter of 35.81 mm and a maximum installation height of 37.59 mm. It connects via wire leads positioned at the top.

Feature Summary

• Piezo-driven internal chime mechanism
• IP68 waterproof and dust-tight enclosure
• Wide DC voltage compatibility
• Panel mount construction

Applications

• Industrial equipment status signaling

Procurement Notes

Verify the specific suffix against official documentation to confirm exact lead time and packaging details. Confirm UL/UR approval requirements for the target application. Ensure the operating environment remains within the specified temperature range. Validate that the 70 dB SPL meets acoustic requirements at the intended distance. Check for any specific mounting hole diameter constraints based on the 35.81 mm diameter specification.

Selection Notes

Select this component when a rugged, waterproof audible indicator is required for harsh environments. The IP68 rating makes it suitable for applications exposed to moisture or dust. The wide voltage range allows flexibility in power supply design. Consider the 70 dB output level relative to ambient noise levels. Verify that the wire lead termination method fits the available wiring infrastructure.

Part Context

This part is part of the Audiolarm II series from Floyd Bell Inc., designed for reliable audible signaling. The series typically includes various voltage and frequency options. The CH-V09-525-S(M) variant specifically offers piezo technology and high ingress protection. It serves as a direct replacement for older chime alarms requiring similar form factors and environmental ratings.

Replacement Considerations

Check for direct substitutes within the Audiolarm II series with matching voltage and SPL. Verify physical dimensions if space is constrained. Ensure the replacement maintains the IP68 rating if environmental exposure is a factor. Confirm that the new part supports the same DC voltage range and current draw.
