Overview
The CH-09-201-S(F) is a panel mount piezoelectric chime alarm from the AudioLarm II series manufactured by Floyd Bell. It features an internally driven indicator circuit and accepts DC input within a voltage range of 5 to 25 volts. The device operates at a frequency of 2.9 kHz with a sound pressure level of 70 dB measured at 5V and 61 cm distance. Power consumption ranges from 5 to 25 mA depending on the applied voltage. The unit is rated IP68 for dust tightness and waterproofing, suitable for operation between -20°C and 65°C. Physical dimensions include a 35.81 mm diameter and a maximum installation height of 37.59 mm.
Feature Summary
- Internally driven piezoelectric technology for reliable chime signaling
- IP68 ingress protection rating ensuring dust tight and waterproof performance
- Wide operating voltage range supporting 5 to 25 VDC inputs
- Panel mount design with top ported wire leads
Applications
- Industrial machinery status indication
- Control panel alarm systems
- Automated equipment safety warnings
- Heavy-duty environmental monitoring stations
Procurement Notes
Verify the specific suffix (F) indicates wire lead termination configuration against official datasheets. Confirm IP68 sealing integrity requirements match application environment. Ensure voltage supply aligns with the 5-25V DC operational range to prevent driver circuit damage. Check UL/UR approval agency listings for compliance in regulated installations.
Selection Notes
Select this model when high durability and water resistance are required for panel-mounted audio alerts. The internally driven feature simplifies integration by removing external driver components. Consider the 70 dB SPL output for environments requiring moderate audible warning levels. Verify physical clearance for the 37.59 mm height constraint during enclosure design.
Part Context
This component belongs to the AudioLarm II series, recognized as a widely used industrial alarm line. It serves as a durable alternative to standard buzzers in harsh conditions. The product maintains active status within the manufacturer's portfolio for new designs.
Replacement Considerations
Cross-reference with other AudioLarm II variants for different mounting styles or voltage specifications. No direct public substitute part numbers are confirmed for this specific model.
