CDVI CA-A470-A Expansion module for two-door access control

 

Expand your access control system for part of the price of an entire controller with the 2-door expansion module. Provide 8-door access control with up to 3 modules connected to the controller's E-bus. E-bus technology allows each module to be located up to 1220 meters from the CT-V900A controller, which reduces wiring and creates convenience for the installer - the expansion modules to be closer to the doors. Each module supports 2 readers and / or 2 keyboards. Communicates with the controller via a fast, secure RS-485 e-bus.
