Discontinued: MB Series Motor Bells



    • High sound output for improved alerting capabilities
    • High efficiency, low current motor
    • Low starting voltage
    • Fully‑enclosed mechanism
    • Durable keyed steel gong and striker

    These Wheelock motor bells use a high‑quality, micro‑motor operating mechanism. This provides long-term reliability, low starting voltage, and extremely low current consumption. These features enable the use of more bells per circuit and greater alarm signal distribution than conventional bells. The low starting voltage provides a stronger signal on marginal circuits.
