6] CONNECTING THE BACKUP BATTERY
The CAA480A uses a 12VDC, 7Ah gel cell battery for its backup power supply.
To connect the backup battery:
1. Connect the "+" terminal of the battery to the "BAT+" terminal of the CAA480A.
2. Connect the "-" terminal of the battery to the "BAT-" terminal of the CAA480A.
The "BATT" LED will remain illuminated during normal operation. If the battery's voltage
drops below 10.5V, the "BATT TROUBLE" LED will light up. Refer to Figure 4 for more
details.

7] FLOOR CONTROL CONNECTIONS
The CAA480A's floor control relays can be connected directly to the elevator's floor
buttons. Since the elevator is connected directly to the CAA480A, the user will then have
to present their valid access card to the reader in the elevator car in order to access the
floors.
The CAA480A can be connected using two methods, the Standard Button Control
connection method, or the Security Enabling Control connection method.
STANDARD BUTTON CONTROL CONNECTION
This is the most commonly used connection method in elevator control applications.
The elevator car's floor selection buttons are controlled using the CAA480A's floor
control relays. The Standard Button Control connection method can be applied in
Fail-Safe mode or Fail-Secure mode. Please note that for UL / ULC installations, the
button control connection must be configured in Fail-Safe mode.
It is recommended that the voltage of the CAA480A's floor control relays do not exceed 24VDC.
It is very important that a trained and registered elevator service company connect any wiring

associated with any components of the elevator system, this includes the wiring of the CAA480A's
floor control relays.
Installation must comply with
local codes and ordinances.
