Dahua DEE1010B – Access Control Extension Module, RS-485, NO/NC Lock Output

The Dahua DEE1010B is an access control extension module designed to expand the functionality of Dahua VTO outdoor door stations. Installed inside a standard 86 mm × 86 mm gang box, it communicates with the host device via RS-485 bus to enable second-lock control directly from an indoor monitor or management software (DMSS, DSS Client). It is well suited for security portals (mantrap configurations) or any installation requiring independent control of a secondary entrance.
