Upgrade your 3G BFT or AES cell intercom system to 4G with this replacement board. Before purchasing, confirm that your current board is red, as other versions may not be compatible and could require a keypad replacement.
Key Compatibility Notes:
- Power Supply Requirement: This board operates on 24V, whereas 3G models used 12V. A new power supply is required (see Related Items below).
- Replacement for Certain 4G Units: If your existing 4G unit has a yellow circuit board with a black modem daughterboard, it cannot receive remote firmware updates needed for AT&T network changes. This board serves as a direct replacement.
- Firmware Updates: Some installations may require firmware updates. Refer to the Cell Phone Intercom Firmware Upgrade guide for details.
Important Ordering Information:
- Troubleshooting Required: Before ordering, contact AES technical support to confirm whether your existing board is defective.
