CH-V09-525-W(M)

Overview

The CH-V09-525-W(M) is a piezoelectric chime alarm from the AudioLarm II series by Floyd Bell Inc. Designed for panel mounting, it features an internally driven indicator circuit and wire leads. The device operates on a DC voltage range of 5 to 25V with a current draw of 5 to 25mA. It produces a sound pressure level of 70dB at 5V measured at 61cm and emits a tone at a frequency of 2.9kHz. The unit is rated IP68 for dust tightness and waterproofing, ensuring durability in harsh environments. Operating temperatures range from -20°C to 65°C. Physical dimensions include a diameter of 35.81mm and a maximum installation height of 37.59mm.

Feature Summary

• Piezoelectric technology provides reliable acoustic signaling without external drivers.
• IP68 rating ensures protection against dust ingress and water immersion.
• Internally driven circuit simplifies integration into control systems.
• Panel mount design with top port location facilitates direct enclosure installation.

Applications

• Industrial automation machinery status indication
• HVAC system fault alarms
• Commercial appliance safety warnings

Procurement Notes

Verify the suffix designation carefully during procurement. The model CH-V09-525-W(M) specifies the terminal configuration and housing material variant. Confirm that the required operating voltage aligns with the 5-25V DC specification. Ensure the panel cutout dimensions accommodate the 35.81mm diameter. Cross-reference the UL/UR approval requirements with local safety regulations before finalizing the purchase order.

Selection Notes

Select this component when high environmental resistance is required due to its IP68 rating. The wide voltage input range allows compatibility with various industrial power supplies. Consider the 70dB SPL output for applications requiring audible alerts in moderately noisy environments. The internally driven nature reduces component count in the design. Verify that the 2.9kHz frequency meets specific auditory notification standards for the target application.

Part Context

This part belongs to the AudioLarm II series, which focuses on robust industrial signaling solutions. Floyd Bell Inc manufactures these devices for demanding environments where reliability is critical. The series typically includes various voltage and mounting configurations. This specific model emphasizes waterproofing and durable construction suitable for outdoor or washdown areas.

Replacement Considerations

Direct substitutes must match the 2.9kHz frequency, 70dB SPL, and IP68 rating. Verify physical dimensions to ensure fit within existing panel cutouts. Check if alternative models offer compatible wire lead termination types. Ensure the replacement maintains UL/UR certification if required by the original equipment specifications.
