Alarms, Buzzers, And Sirens Procurement Notes

Verify that the specific suffix (F) matches the required lead termination style. Confirm the operating voltage aligns with the 5-25V DC specification to ensure proper current draw. Check environmental requirements against the IP68 rating and temperature range. Ensure panel cutout dimensions accommodate the 35.81 mm diameter. Validate UL/UR approval compliance for the intended application region.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a rugged, waterproof audible indicator is required for harsh environments. The wide voltage range allows flexibility in system design without external drivers. The high ingress protection rating makes it suitable for outdoor or washdown applications where standard indicators would fail. Consider the 70 dB SPL output for noise attenuation levels in the installation area.

Alarms, Buzzers, And Sirens Part Context

This part is part of the Audiolarm II family of piezo chimes. It shares the same form factor and mounting characteristics as other models in the series, such as the CH-V09-525-W(F). The primary differentiators are typically the acoustic tuning and electrical specifications. This model provides a standardized solution for industrial signaling needs requiring robust construction.

Alarms, Buzzers, And Sirens Replacement Considerations

Cross-reference with other Audiolarm II models like CH-V09-525-W(F) if physical fit is the priority. Verify that substitute parts match the 2.9 kHz frequency and 70 dB SPL requirements. Ensure replacement units also carry UL/UR certification if safety approvals are mandatory for the end product.
