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.
