초록 ▼

The invention relates to a mail box alarm system arranged to notify the owner of a rural mail box when mail has been received. A transmitter positioned in the mail box radiates a coded signal each time the door of the box is opened or closed. A receiver, positioned in the associated residence or business, operates a visual and audible alarm. When mail is delivered, both the visual and audible alarm are energized during the time the door is open for the delivery of mail. When the door is closed, only the visual alarm remains energized. When the mail is picked up, the visual alarm is automatically deenergized and the mechanism re-positioned for a new cycle.
