How To: change the site code of a D8229 Access Keypad

[#1]

Solution

1. Remove power from the D8229 by disconnecting the Red wire from input voltage
2. Connect the Pink wire to the Black wire.
3. Reconnect power to the D8229 by reconnecting the Red wire to input voltage.
1. 4 rapid beeps will be heard and both the Red and Green LEDs will flash at the same rate
4. Enter a new Site Code between 1-255 and press #.      
1. An error tone will sound if a site code higher than 255 is entered.
2. After entering the new Site Code the keypad will sound 4 rapid beeps and both LEDs will flash 4 times. The D8229 will appear inoperative and not accept additional entries once the new entry is completed.
3. To correct a wrong entry, press the star [ * ] key instead of # . The keypad will sound 2 rapid beeps and both Green LEDs resume flashing at the same rate. Enter the correct site code and then press #.
5. Remove power from the D8229 by disconnecting the Red wire.
6. Remove the Pink wire from the Black wire.
7. Reconnect power to the D8229 by connecting the Red wire and returning to normal configuration

The following WIEGAND output is sent each time the # (enter) key is pressed:

	Even Parity for bits 2-13	Bits 2-9: Site Code	Bits 10-25: User Pin Number to be entered followed by #	Odd Parity for Previous 12 Bits
	P	S	S	S	S	S	S	S	S	N	N	N	N	N	N	N	N	N	N	N	N	N	N	N	N	P
BIT	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15	16	17	18	19	20	21	22	23	24	25	26
D8229 Reader Bit Output

• BIT 1 is an even parity for the following 12 bits. The sum of bits 1-13 is even.
• BITS 2-9 are the SITE CODE.
• BITS 10-25: This is the number (PIN) entered prior to pressing # (enter).
• Leading 0's are added as required. Bit 10 is most significant.
• BIT 26 is an odd parity over the previous 12 bits. The sum of bits 14-26 is odd.
• Example: Site Code of 004 and a code of 123 entered:

1 0 0 0 0 0 1 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 0 1 1 1

Note: An error code which sends all binary 1's to your panel is generated by any of the following:

1. Pressing the # key with no preceding digits.
2. Pressing any number of only 0's prior to pressing the # key
3. Pressing 65,535 or any number above 65,535. Do NOT program your panel to accept code number 65,535.
