When connected to the CTV900ATR controller’s expansion bus, each CAA-480A can control up to 16 floors. The CAA-480A floor control relays can be interfaced directly with an elevator’s floor control buttons. When a valid card is presented, the appropriate floor control relays will be activated, allowing the cardholder to select the desired floor. In addition to these advanced floor and elevator control features, the CAA-480A also offers full monitoring, a backup battery, and a fire alarm input.
