Procurement Notes
Verify the specific suffix EPQ against official Mallory Sonalert documentation to confirm exact acoustic and electrical characteristics. Ensure the operating environment temperature range aligns with standard piezoelectric specifications. Confirm that the wire lead termination type matches the target assembly requirements before finalizing procurement orders.
Selection Notes
Select this component when a compact, high-intensity audible alert is required for panel-mounted applications. The 3.5 kHz frequency provides distinct audibility in noisy environments. The flange mount option simplifies mechanical integration compared to through-hole variants. Consider the 15 mA current draw for power budget calculations within the control circuitry.
Part Context
This part belongs to the PK series of piezoelectric indicators manufactured by Mallory Sonalert Products Inc. The series is designed for industrial and commercial applications requiring robust audio signaling. These devices are known for their durability and consistent performance across various environmental conditions, serving as standard components in safety and notification systems.
Replacement Considerations
Consult official Mallory Sonalert cross-reference guides for verified substitutes. Direct replacements must match the 30 mm diameter, 3.5 kHz frequency, and flange mount configuration. Verify voltage compatibility and acoustic output levels to ensure functional equivalence in the existing assembly.
