Sonalert® SC628

The Mallory Sonalert LSC628ANR is a compact 30mm panel-mount audible alarm with a red LED indicator, designed to provide both sound and visual notification in control panels, equipment systems, and marine electrical applications. With a continuous 2900 Hz tone, a loudness range of 88–99 dBA at 2 feet, and a wide 9–28V AC/DC operating range, this alarm is well suited for warning circuits, system alerts, fault indicators, and status notifications where clear signaling is essential. Its black 6/6 nylon housing, screw terminal mounting, and broad operating temperature range make it a practical choice for durable panel-based installations.
