AI summary

Example implementations include an addressable device having a base unit mountable on a structure and a device head removably mountable onto the base unit. A removable addressing mechanism is removably mountable onto the base unit and is configured for setting an address for the addressable device. The device head includes an optical address detection mechanism that, when the device head and the removable addressing mechanism are mounted onto the base unit, is configured to align with the removable addressing mechanism to optically read the address configured in the removable addressing mechanism. The removable addressing mechanism is electrically isolated from the base unit, the device head, and the optical address detection mechanism.
