204330

Overview

The Moflash Signalling Ltd model 204330 is an externally driven piezo transducer designed for acoustic signaling applications. It operates at a nominal voltage of 24 V and draws a current of 35 mA. The device produces a sound pressure level of 108 dB when measured at the specified operating voltage. Mechanical installation is facilitated by a base mount configuration, which utilizes screw terminals for electrical connection. This component serves as a core element within larger alarm or warning systems requiring reliable audible output.

Feature Summary

• Externally driven piezoelectric transducer design
• Base mount mechanical construction with screw terminal connections

Applications

• Fire alarm system acoustic signaling
• Industrial alarm and warning devices
• Explosion-proof intrinsically safe sounder units

Procurement Notes

Verify that the specific application environment matches the device's operational ratings. Confirm that the power supply provides stable 24 V DC to ensure correct current draw and sound output levels. Ensure mounting hardware supports the base mount style and that wiring methods comply with screw terminal specifications. Check for required certifications such as EN54-3 if used in fire safety circuits.

Selection Notes

Select this component where high-decibel audible signaling is required from a compact piezo source. Consider the 24 V operating requirement against available system voltages. Evaluate the need for external driving circuitry versus integrated sirens. Assess whether the base mount form factor fits the enclosure design constraints compared to panel-mount alternatives.
