ABSTRACT:
A mailbox for the reception and protection of mail comprises a mail receptacle or container with a door, an alarm system control switch, responsive to the opening and closing of the mailbox door to activate an alarm when the door is open, illuminating means to light an area near the mailbox and intercommunication means for identification of and conversation with a caller or person using the mailbox. The mentioned security features of the mailbox are components of a pre-wired unit and installation is thereby greatly simplified and facilitated.
