On a Honeywell Vista, the “House Code” is a two-digit identifier used to allow the panel to communicate with bi-directional wireless devices (like the 5827BD or 5804BDV fobs). You must enable this through the system’s programming mode.
- Enter Programming Mode:
- Enter your Installer Code (default is 4112) followed by 800.
- If you don’t know your code, use the backdoor method: Power down the system (battery and AC), power it back up, and press
*and#simultaneously within 50 seconds.
- *Navigate to Field 24:
- Once in programming (the screen should display “Installer Code 20” or just “20”), press *24.
- Enter the House Code:
- The keypad will prompt for the code for each partition.
- Partition 1: Enter a 2-digit number from 01 to 31.
- Partition 2: Enter a 2-digit number (if used).
- Common Partition: Enter a 2-digit number (if used).
- Note: If you only use one partition, enter the 2-digit code for the first and then press * to move forward..
- Verify the Entry:
- To view what is currently programmed without changing it, press #24. The keypad will flash the digits one by one.
- Exit Programming:
- Press *99 to save and exit. *Do not use 98, as it can lock you out of programming mode.
Important Considerations
- Interference: If you have neighbors with similar systems, ensure your House Code is unique to prevent their devices from triggering your panel.
