The SC628P is a medium sound level piezoelectric audible alarm designed for panel-mounted applications requiring fast pulse notification. It operates across a wide voltage range of 6 to 28 VDC with a frequency of 2900 Hz ±500 Hz, delivering a minimum of 68 dB(A) at 6 VDC and a maximum of 80 dB(A) at 28 VDC (both measured at 2 feet). The device features a fast pulse mode with a 50% duty cycle, pulse rates ranging from 2 pulses per second at 6 VDC to 10 pulses per second at 28 VDC, and current draw of 4 mA maximum at 6 VDC and 16 mA maximum at 28 VDC. Housed in black 6/6 nylon with brass tin-plated terminals tapped for #6-32 screws, the SC628P is suitable for alarm systems, warning indicators, and notification applications in industrial control panels, automotive systems, and consumer electronics requiring reliable audible feedback across varying supply voltages.
