MC-V09-531-Q

Alarms, Buzzers, And Sirens Overview

The MC-V09-531-Q is a piezoelectric chime alarm manufactured by Floyd Bell Inc, belonging to the Audiolarm II series. Designed for panel mounting, this internally driven indicator utilizes a DC input voltage range of 5 to 25 volts. It operates at a frequency of 2.9 kHz with a sound pressure level of 70 dB measured at 5 volts and 61 cm distance. The device draws between 5 and 25 mA of power. Physical dimensions include a diameter of 1.410 inches (35.81 mm) and a maximum installation height of 1.480 inches (37.59 mm). It features wire leads for termination and top port positioning. The unit is rated IP68 for dust tightness and waterproofing, with an operating temperature range of -20°C to 65°C, and holds UL and UR approvals.

Alarms, Buzzers, And Sirens Procurement Notes

Verify the specific suffix configuration against the manufacturer's current datasheet to ensure compatibility with required voltage and acoustic specifications. Confirm that the wire lead length and termination style meet the integration requirements of the target assembly. Check for any recent updates to the Audiolarm II series documentation regarding material changes or certification renewals before finalizing procurement orders.

Alarms, Buzzers, And Sirens Selection Notes

Select this component when a sealed, high-reliability chime is required for harsh environments due to its IP68 rating. Ensure the driving circuit can supply the necessary 5 to 25 mA current within the 5 to 25 VDC range. Consider the physical constraints of the panel cutout and depth, as the unit requires a 1.410-inch diameter hole and up to 1.480 inches of clearance behind the panel.

Alarms, Buzzers, And Sirens Part Context

This part belongs to the Floyd Bell Audiolarm II series, which focuses on robust, internally driven piezoelectric indicators. The series is characterized by its ability to operate directly from DC sources without external drivers, making it suitable for straightforward integration into various electronic assemblies where space and simplicity are prioritized.

Alarms, Buzzers, And Sirens Replacement Considerations
