UW-09-628-S(S)D

Overview

The Floyd Bell Inc. UW-09-628-S(S)D is a piezoelectric panel mount chime alarm from the AudioLarm II series. It operates on a DC input voltage range of 5 to 25 volts with an internally driven circuit. The device produces a sound pressure level of 70 dB at 5V measured at 61 cm and functions at a frequency of 2.9 kHz. Power consumption ranges from 5 to 25 mA depending on the applied voltage. The unit features wire leads for termination and is designed for top port placement. It supports an operating temperature range of -20°C to 65°C and holds UL and UR approval agencies. The physical dimensions are 1.410 inches in diameter and 1.480 inches maximum height, with IP68 dust-tight and waterproof protection.

Feature Summary

• Internally driven piezoelectric chime mechanism
• IP68 rated for dust tightness and waterproofing
• UL and UR approved safety certification

Applications

• Panel mounted industrial equipment alarms
• Waterproof control cabinet indicators
• Dust-exposed machinery status signals

Procurement Notes

Verify that the specific suffix (S)(D) matches the required lead configuration and mounting hardware specifications. Confirm that the 5-25V DC operating range aligns with the system power supply. Ensure the IP68 rating meets environmental exposure requirements. Check for UL/UR listing compliance against local regulatory standards. Validate physical dimensions against panel cutout constraints before procurement.

Selection Notes

Select this component when a self-contained, internally driven audible indicator is required for harsh environments. The wide voltage tolerance allows flexibility in power distribution systems. The IP68 rating makes it suitable for outdoor or washdown applications where standard components would fail. Consider the 70 dB output level relative to ambient noise conditions. Verify that the wire lead termination style fits the assembly wiring method.
