Procurement Notes
Verify the specific ordering suffix against the official Mallory Sonalert datasheet to confirm the exact voltage range and LED color configuration. Ensure the terminal block type matches the existing wiring infrastructure. Confirm RoHS compliance requirements align with project specifications before finalizing procurement orders.
Selection Notes
Select this model when a high-decibel audible alert combined with a visual indicator is required for 90-120 VAC applications. The 22mm panel cutout dimension dictates compatibility with standard industrial enclosures. Consider the 40 mA current draw for power supply sizing and verify that the terminal block connection method suits the available wiring harnesses.
Part Context
This component belongs to the ZT series of industrial alarms from Mallory Sonalert. The series is characterized by robust piezoelectric transducers designed for demanding environments. The ZT120LACTB30 specifically addresses needs for loud, continuous warnings in sectors requiring both auditory and visual feedback mechanisms for immediate operator awareness.
Replacement Considerations
Consult the official Mallory Sonalert cross-reference guide for verified substitute part numbers. Ensure any replacement maintains the 22mm panel mount footprint and compatible voltage input range. Verify that acoustic output and electrical characteristics match the original design requirements.
