The OCB8 is a durable and reliable Form-C relay output board designed as a dry contact closure for Keyscan’s door and elevator floor controllers, and auxiliary equipment. The Keyscan OCB8 provides auxiliary service expansion such as additional doors or elevator floor stops.

OCB8 can also trigger secondary responses such as sirens, alarms, strobe lights or increase access restriction parameters with the Keyscan EC1500, EC2500, CA4500, or CA8500 controllers. The OCB8 is time programmable and features a DIP switch bank for easy changes to state of relays.
