Keyscan OCB8 Form-C 8 Relay Output Control Board, Auxiliary Service Expansion

Streamline auxiliary output expansion for your access control system with the Keyscan OCB8 Form-C Relay Output Board by dormakaba. Designed for integrators and facility managers, this auxiliary service expansion board delivers eight programmable Form-C dry-contact relays so you can add doors, elevator floor stops or external alarm/strobe/siren responses without replacing core controllers.

The OCB8 is time‑programmable and includes a DIP switch bank with independent reverse-pole switches for rapid on-site configuration, minimizing downtime and labor costs. Its compatibility with Keyscan EC and CA series controllers (including EC1500, EC2500, CA4500 and CA8500) ensures smooth integration into existing security and monitoring infrastructures. Use the OCB8 to trigger secondary responses, escalate access restrictions, or coordinate with surveillance and alarm systems for a cohesive security strategy.

Ideal for commercial buildings, multi-tenant facilities and institutions, the OCB8 enhances system flexibility and reliability while keeping installations tidy and cost-effective. Add the OCB8 to your Keyscan setup to expand outputs, improve alarm integration and simplify field configuration—contact your dormakaba reseller to specify the right configuration for your project.
