Legacy ASR-503

The Legacy Mullion proximity reader, formally known as the "ASR-503 SlimLine", is a member of Indala's proximity card and reader family. Designed to mount on metal door frame (mullion) or a flat surface, it is also suitable for locations that require a small footprint reader.

The single-piece Legacy Mullion Reader delivers read ranges up to 4 inches (10 cm) and operates from 4 to 16 VDC allowing for great flexibility in power supplies. In most cases, it can be powered directly from the access control panel. The electronics are sealed in a UL-approved epoxy potting material, making the reader vandal and weather resistant.
