Claim:
A fencing system including a plurality of spaced posts joined by fencing wire for providing perimeter security comprising: (a) at least one post having one or more cabinets; (b) one or more strands of said fencing wire operatively coupled to said at least one post, the one or more strands of fencing wire operatively connecting the at least one post to other posts of said plurality of spaced posts in the fencing system; (c) a sensing mechanism being held by a cartridge, a first member of the sensing mechanism protruding from the cartridge, the first member operatively coupled to one fencing wire strand of the one or more, strands of fencing wire, the sensing mechanism configured to trigger an alarm condition if the one fencing wire strand coupled to the first member is deflected with a sufficient amount of force, the cartridge being releasably held within a channel of one cabinet of said one or more cabinets, the channel having a size which mates with the cartridge in order to enable both slidable removal and slidable insertion of the cartridge with respect to the channel; and (d) a first bus bar and a second bus bar located proximate to the sensing mechanism, said first bus bar and said second bus bar being retained, by the one cabinet so as to make contact with distinct electrically conductive elements of the cartridge upon insertion of the cartridge within the channel.
