Aiphone JOW-2D Adapter for JO Series Video Intercom System

Add a second entry point to your JO Series intercom quickly and reliably with the Aiphone JOW-2D two-door adapter. Designed for installers and security managers, this interface adapter enables two JO Series video door stations to operate on a single standard or app-enabled system (compatible with JO-1MDW and JO-1MD masters), extending surveillance and visitor monitoring without replacing existing equipment. The JOW-2D provides independent door-release outputs so staff can grant access to the exact door requested, reducing lock control errors and improving site access control workflows.

Built for wired deployments, the module accepts an 18V DC input and mounts easily on a wall or surface, making retrofits and system expansions fast and cost-effective. Its call-management logic prevents simultaneous calls from creating confusion, helping reception and security personnel maintain professional monitoring and response. NDAA compliance ensures the module meets procurement requirements for many public and enterprise projects. Ideal for commercial offices, multifamily properties, and light industrial sites—add the JOW-2D to extend your security and surveillance coverage today.
