Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific part number suffix against official Mallory Sonalert documentation to ensure correct sound mode and voltage compatibility. Confirm that the required operating environment falls within the specified temperature range of -30°C to 65°C. Check for necessary certifications such as UL or cUL if applicable to your region's safety standards. Ensure the panel cutout dimensions match the physical size specifications provided in the datasheet.

Alarms, Buzzers, And Sirens Selection Notes

Select this model when a medium pulse tone is required for attention-grabbing alerts in noisy environments. The 95 dB output provides higher audibility compared to soft or standard variants. Consider the 40 mA current draw for power supply sizing. The terminal block connection style suits applications requiring secure wiring without soldering. Verify that the 16-28V operating range aligns with the available system power rails.
