Burglar alarm system for multi-unit mailboxes
First Claim
1. A multi-unit mailbox alarm system for generating an alarm signal in response to the unauthorized opening of an access door disposed over a plurality of mailbox compartments, said door being secured by a postal lock of the type having linear actuation linkage therein, and said alarm system comprising:
- a first sensor disposed between said access door and said mail compartments therebehind;
a second sensor disposed relative to said postal lock for detecting the linear actuation thereof;
an interconnection coupling said first sensor to said second sensor for relaying the state of said second sensor disposed relative to said postal lock, said interconnection being disposed relative to said first sensor and said second sensor; and
means for generating an alarm signal in response to sensing the unauthorized opening of said access door through said first sensor without first actuating said second sensor through said postal lock and transmitting the state of said second sensor through said interconnection to said first sensor.

Abstract
Alarm system for multi-compartment, postal mailbox arrays incorporating a plurality of individual mail compartments contained behind a primary access door. The system comprises an alarm secured adjacent the mailbox array and coupled thereto by switches coupled to each access door and to the postal lock for that door. The postal lock is modified with an aperture which exposes the internal operation thereof for a switch mounted thereon. In this manner authorized actuation of the lock disengages the alarm system to prevent it from sounding when the access door is opened. Forced opening of the access door without first disengaging the system through the postal lock will otherwise set off the alarm. In this manner a number of access door switches may be coupled to a single alarm box which itself may be constructed for preventing unauthorized deactivation by the utilization of similar switch sensors disposed therein.

19. A method of generating an alarm signal in response to the unauthorized opening of an access door disposed over a plurality of mailbox compartments with said door being secured by a postal lock the type having linear actuation linkage therein, said method comprising the steps of:
-
providing a first sensor; disposing said sensor relative to said access door to detect the opening thereof; providing a second sensor; disposing said second sensor relative to said postal lock for detecting the actuation thereof; providing an interconnection coupling said first sensor to said second sensor; disposing said interconnection relative to said first sensor and said second sensor; and providing means for generating an alarm signal in response to sensing the unauthorized opening of said access door through said first sensor without first actuating said second sensor through said postal lock and transmitting the state of said second sensor through said interconnection to said first sensor. - View Dependent Claims (20, 21, 22)
