LiftMaster CAP4EXPND 4AP I/O Expansion Board

Scale your access control with minimal downtime using the LiftMaster CAP4EXPND 4AP I/O Expansion Board. Designed as a plug‑in expansion for the CAPXAP family, this control panel module adds four additional access points per board so you can expand doors, gates or elevator landings without replacing an existing chassis. The CAP4EXPND integrates seamlessly into LiftMaster’s Smart Access Controller ecosystem—compatible with OSDP and Wiegand readers—and works with centralized myQ community connectivity for unified security and monitoring.

Installers will appreciate the straightforward fit-and-wiring design that reduces labor and cable runs, while facility managers gain the flexibility to incrementally scale security across multi-entry properties. By consolidating I/O on a dedicated expansion board, you simplify surveillance integration, alarm monitoring and elevator logic handling within your existing infrastructure. Ideal for commercial buildings, gated communities and multi-tenant facilities, the CAP4EXPND provides reliable, professional-grade performance for growing access control deployments.
