The Lowell KL100 series is designed for AV integrators and systems contractors who need lockable, reliable volume control in critical paging, life-safety, and background music installations. The autoformer attenuator topology preserves audio quality across the attenuation range while the key-switch activation prevents unauthorized adjustment, a requirement in facilities like schools, hospitals, houses of worship, and commercial buildings where consistent paging or emergency audio levels are non-negotiable.
Each unit ships with a one-gang decora-style wall plate and terminates via Phoenix-style connectors, accommodating up to 14-gauge wire and fitting directly into a standard electrical box. The 100W power rating supports single or multiple speaker lines on 25V or 70V distributed systems, making the KL100 a practical choice for zone control in both new construction and retrofit installs. Select bypass-equipped variants include a priority relay that hands control to an emergency or paging system automatically, a critical compliance feature for life-safety applications.
Available in multiple finish and bypass configurations to match facility aesthetics and system architecture, the KL100 family gives integrators the flexibility to specify a single product line across an entire project regardless of room finish or emergency override requirements.
