CH-09-525-Q(M)

Overview

The CH-09-525-Q(M) is a panel mount chime alarm from the AudioLarm II series by Floyd Bell Inc. It utilizes piezoelectric technology and features an internally driven indicator circuit. The device operates on a DC voltage range of 5 to 25 volts with a frequency of 2.9 kHz. It produces a sound pressure level of 70 dB at 5V measured at 61 cm. Power consumption ranges from 5 to 25 mA. The unit has an IP68 rating for dust tightness and waterproofing, suitable for harsh environments. Operating temperature spans from -20°C to 65°C. Physical dimensions include a 1.410-inch diameter and a maximum installation height of 1.480 inches.

Feature Summary

• Piezoelectric construction providing durable audio signaling
• IP68 rated enclosure ensuring protection against dust and water ingress
• Internally driven indicator circuit for simplified integration
• Panel mount design with top ported output

Applications

• Industrial machinery status indication
• Harsh environment equipment alarms
• Waterproof control panel signaling

Procurement Notes

Verify the specific suffix (Q/M) against official datasheets to confirm exact acoustic or electrical variations within the AudioLarm II family. Ensure mounting hole dimensions align with the specified 1.410-inch diameter. Confirm voltage requirements match the 5-25V DC operating range for the target application.

Selection Notes

Select this component when high environmental protection (IP68) is required alongside audible alerting. The internally driven nature simplifies wiring compared to passive buzzers. Consider the 70 dB SPL output for noise levels up to moderate industrial volumes. Verify that the 2.9 kHz frequency meets regulatory or user preference standards for the specific installation site.

Part Context

This part belongs to the AudioLarm II series, described as a widely used industrial alarm line. Floyd Bell manufactures these devices for durable industrial machines. The series includes various tones and voltages, with this specific model focusing on piezoelectric chime functionality in a robust, sealed package.

Replacement Considerations

Cross-reference with other AudioLarm II models for similar voltage and SPL ratings. Verify physical footprint compatibility if replacing existing units. Check if alternative manufacturers offer IP68 rated piezo alarms with comparable 2.9 kHz frequencies and internal drive circuits.
