AWID SR-2400-GR-0 Mullion Reader - Reliable 4 to 5.5in Read Range

Our review of the AWID SR-2400-GR-0 mullion reader finds it best suited for installers and property managers who need a compact, durable card reader for doorframes and narrow mounting locations. The bottom line: this Wiegand-only mullion reader delivers a consistent 4 to 5.5in read range in a slim gray housing, making it a practical choice when space is limited and integration with existing access control systems is required. Its simplicity and predictable performance are the single biggest reasons to buy.

Key Features

• Wiegand interface: Integrates with most access control panels to allow straightforward connection and central management.
• 4 to 5.5in read range: Provides reliable card detection for typical proximity credentials while keeping accidental reads minimal on narrow mounts.
• Mullion mounting width: Slim profile designed specifically for mullion or narrow frame installation where a full-size reader will not fit.
• Indoor/outdoor capability: Built to work in both sheltered exterior and interior doorframe locations for flexible deployment.
• Gray finish: Neutral color that blends with most commercial and residential doorframes for unobtrusive installation.

Who It's For

This reader is ideal for security integrators, facilities teams, and installers who need a compact reader that conforms to mullion mounts and connects to Wiegand-based access control systems. It suits offices, small businesses, and multi-tenant buildings where a slim, unobtrusive card reader is required.

Customers who need multi-protocol support, built-in credentials, or wireless/standalone battery operation should look elsewhere, since this model is explicitly a Wiegand-only device focused on reliable wired integration rather than feature-rich standalone operation.

Pros & Cons
