Several of First Alert's residential security alarm systems utilize the FA-215 keypad as their user interface. The FA-215 is a fixed-word type of keypad, which means that it uses predetermined words to describe events taking place in the system. Homeowners can set up multiple users, each with a personal alarm code. This makes it easy to regulate the access of certain users.
Change Master Code
Enter the current four-digit master code and then press the "8" key.
Enter the user number, which is always "02" for the master code.
Enter the new four-digit code, two times. This is to verify that you have entered the code you desired.
Change User Code
Enter the four-digit master code and press "8."
Enter the two-digit user number of the person whose code you wish to change. This number will be between 03 and 16.
Enter the user's new four-digit code. You only have to enter the new user code once.
You can never let more than two seconds pass between number entries when changing the code. All three steps must be performed together. If you take longer than two seconds between an entry, you'll have to repeat the procedure. The master code is selected during installation. If you forget it, a technician will have to reset it.
