Napco GEM-2D Second Door Access Control Accessory Module

Improve facility security and streamline access management with the Napco Security Technologies GEM-2D Second Door Access Control accessory module. Designed as a companion Control Panel Module for the GEM-ACM1D and GEM-X255 systems, the GEM-2D adds independent second-door control so you can deploy a separate card reader and relay without adding a full secondary controller. That means faster installation, reduced hardware expense, and centralized monitoring of door activity within your existing security infrastructure. The module’s compact dimensions (12.17" W x 11" H x 3" D) fit standard control enclosures while delivering reliable relay operation and credential handling compatible with Napco access hardware. Ideal for multi-tenant buildings, IT closets, data centers, or retail back-of-house areas, the GEM-2D improves surveillance and access tracking by integrating door control into your intrusion detection and security monitoring workflows. Expand access capability and reinforce perimeter control with minimal disruption—add the GEM-2D to your GEM-ACM1D/GEM-X255 deployment today or contact us for system integration guidance.

• Adds independent second-door access control to an existing GEM-ACM1D/GEM-X255 system, expanding secured entry without replacing your panel
• Enables a separate card reader and independent relay for flexible credentialing and better traffic segmentation
• Seamless integration with Napco Security Technologies hardware reduces configuration time and centralizes monitoring
• Compact footprint (12.17" W x 11" H x 3" D) for easy installation in equipment racks or control enclosures
• Lowers total system cost by extending access control capability with a single accessory module instead of a full secondary controller
