The DCU-602 alarm system series incorporates several different models of Brinks alarm, including the BSH-2000A, B and C. The system has room for six additional entry codes for family members or employees. Additional entry codes can only be changed using the system's three-digit master code. Replacing an entry code helps ensure your property is completely secure -- a leaked entry code could compromise the effectiveness of your Brinks alarm.
Tap the "Options" button in the lower right corner until "Auxiliary Code Enter Master Code" appears on the display.
Enter your three-digit master code using the numbered buttons. "Enter 1-6" appears on the screen.
Touch the number of the code you are changing. "Enter New Code" appears on the display screen.
Type in a new code using the number buttons. When the keypad emits a confirmation beep, the new code is ready for use.
