UC-09-628-S

Overview

The UC-09-628-S is a piezoelectric chime alarm manufactured by Floyd Bell Inc, belonging to the AudioLarm II series. Designed for panel mounting, this internally driven indicator operates on DC voltage within a range of 5 to 25 volts. It generates an acoustic signal at a frequency of 2.9 kHz with a sound pressure level of 70 dB measured at 5V and 61 cm. The device draws between 5 and 25 mA of current and features wire leads for connection. It is rated IP68 for dust tightness and waterproofing, ensuring durability in harsh environments. The unit operates within a temperature range of -20°C to 65°C and holds UL and UR approvals.

Feature Summary

• Piezoelectric technology provides reliable internal driving for chime operations without external drivers.
• IP68 rating ensures complete protection against dust ingress and water immersion.
• UL and UR agency approvals confirm compliance with safety standards.
• Top-mounted port position facilitates directed sound projection.

Applications

• Industrial machinery status indication
• Security system chimes
• Appliance audio signaling

Procurement Notes

Verify that the specific part number UC-09-628-S matches the required voltage and frequency specifications for your application.
