Product Features
Technical Overview
The D8225 employs proximity technology for contactless credential reading, eliminating physical wear on cards or tokens. Its 3-inch read range provides consistent performance while minimizing accidental triggers. The 16V DC input voltage ensures stable operation within standard access control power supplies, and the reader's internal circuitry is designed for continuous duty in access control applications.
Physical construction emphasizes durability and installation flexibility. The Charcoal Gray housing resists marking and blends with common architectural finishes. With dimensions of 2" H × 4.70" W × 7.30" D and a weight of approximately 76.5 grams, the reader mounts cleanly on mullions or narrow surfaces without protruding excessively.

Key Product Advantages
The D8225 Mini Mullion Reader combines Bosch reliability with a purpose-built form factor for constrained installations. Its proximity method reduces mechanical failure points compared to swipe or insert readers, while the 3-inch range balances detection consistency with security spacing.
Compact Design
With a height of just 2 inches and depth under 7.5 inches, the reader fits seamlessly on narrow door mullions, cabinet frames, or other tight spaces where traditional readers would be too bulky.
- Low-profile housing
- Minimal footprint
- Discreet appearance
Broad Compatibility
Supports Wiegand 26-bit proximity cards, tokens, and adhesive tags, along with integration into Bosch ReadykeyPRO, Readykey, D9412G, and D7412G control panels for flexible system design.
- Multiple credential types
- Bosch panel integration
- Standard Wiegand interface
Deployment / Use Cases
The D8225 is ideal for environments where space constraints or aesthetic considerations rule out larger readers. Its mullion-mount orientation and Charcoal Gray finish suit office buildings, schools, healthcare facilities, and light industrial sites where access control must be effective yet unobtrusive.
Common applications include interior door control in corridors, storage rooms, or equipment cabinets; secondary authentication points in multi-layer security zones; and retrofit installations where existing infrastructure limits mounting options. The reader's compatibility with Bosch control panels makes it a natural choice for expanding or upgrading Bosch-based access systems.
