TUHB-V88W-930-Q(U)

Overview

The TUHB-V88W-930-Q(U) is a panel mount chime alarm manufactured by Floyd Bell Inc. It belongs to the AudioLarm II series and utilizes piezo technology for sound generation. The device operates on a DC voltage range of 5 to 25 volts with an internally driven indicator circuit. It produces a chime at a frequency of 2.9 kHz with a sound pressure level of 70 dB at 5V measured at 61 cm. The unit draws between 5 and 25 mA of current. It features IP68 ingress protection, making it dust tight and waterproof. The physical dimensions are 1.410 inches in diameter and 1.480 inches maximum height. Operating temperature ranges from -20°C to 65°C. It includes wire leads for termination and UL/UR approval agency certification.

Feature Summary

• IP68 rated construction provides dust tight and waterproof protection for harsh environments
• Internally driven indicator circuit simplifies integration into control panels
• Piezo technology ensures durable audio output suitable for industrial machinery
