CDVI AIOM 10-Input/10-Output Expander Module

Extend and simplify your access control and monitoring infrastructure with the CDVI AIOM 10-Input/10-Output Expander Module. Designed for security integrators and building managers, this compact I/O module adds flexible zone and output capacity—10 zone inputs and 10 outputs (expandable to 20 with zone-doubling)—so you can support additional doors, sensors, and alarm points without replacing the main controller. The AIOM connects over a 4-conductor RS-485 expansion bus up to 1220m (4000ft), enabling distributed placement to reduce cable runs and installation costs. Auto-detect technology removes the need for jumpers or DIP switches, and comprehensive LED indicators make status checks and fault diagnosis fast and intuitive. Built for Wiegand and Atrium controller compatibility, the CDVI AIOM integrates smoothly into existing access control, surveillance, and monitoring systems—improving response times and overall system reliability. Ideal for multi-site deployments, CCTV-triggered events, or expanding security zones, the AIOM is a practical choice for scalable, professional security installations. Add the AIOM to your next Atrium project or contact sales to discuss system design.
