Building device having an address programming interface

A building device, comprising:

• a mounting base having a front surface and a rear surface, the front surface defining a plurality of connector channels extending towards the rear surface, a first and a second of the connector channels spaced apart and sized to each receive a respective prong of a connector plug attached to a programming device;
• a plurality of external terminals disposed on the rear surface of the mounting base;
• a plurality of internal terminals;
• a first plurality of normally closed switches having a common control input, each switch of the first plurality of switches connecting a respective one of the external terminals to a respective one of the internal terminals when the common control input is deactivated;
• and
• an actuator connected to the common control input and disposed in proximity of the connector channels such that the connector plug engages the actuator to activate the common control input of the first plurality of normally closed switches when the first and the second connector channels each receive a respective prong of the connector plug.
