ABSTRACT:
A building security system includes an alarm controller for learning a unique remote transmitter code to define a learned transmitter capable of switching the controller between armed and disarmed states. The controller performs learned code verification to generate an indication relating to whether a new remote transmitter has been learned by the controller. In one embodiment, the learned code verification is based upon the alarm controller being recently entered into the learning mode. According to another embodiment, the learned code verification is based upon a number of learned remote transmitters, a change in that number, or a change in the identity of a learned code. The indication may be provided at the building or remote therefrom by any of a light, a visual display, a speech message generator, and an audible signal generator, for example. A previous set of authorized or learned remote transmitter codes may be readily reset or restored to operate the system if unauthorized codes have been more recently added.
