Procurement Notes
Verify the specific suffix codes to ensure correct voltage, tone, and LED color configurations. Confirm terminal block compatibility with existing wiring harnesses. Check RoHS compliance documentation for regulatory requirements. Validate IP rating suitability for the intended environmental exposure conditions.
Selection Notes
Select this model when a continuous 3.9 kHz tone is required alongside a green LED indicator. Ensure the mounting panel accommodates the 22 mm diameter opening. Verify that the 20-28V DC supply matches the system power architecture. Consider the 25 mA current draw for power budget calculations.
Part Context
This component belongs to the ZT series of industrial audio indicators from Mallory Sonalert. The series is characterized by compact form factors and integrated LED functionality. It serves as a specialized solution for applications demanding high visibility and audibility in noisy or complex industrial settings.
Replacement Considerations
Cross-reference part numbers within the ZT series for variations in tone type or LED color. Verify mechanical fitment against alternative models with similar diameter specifications.
