Perimeter breach warning alarm

A perimeter breach warning system comprising:

• a first solid support structure;
• a perimeter breach warning device attached to the first solid support structure, the perimeter breach warning device comprising:
• a main body forming a firing bore therethrough, wherein the firing bore comprises a first firing bore end, a second firing bore end, and an internal firing bore protrusion,
• a holding protrusion at the first firing bore end,
• a firing pin assembly within and extending out from the firing bore, the firing pin assembly comprising:
• a shaft comprising a first shaft end and a second shaft end, wherein the shaft comprises:
• a firing pin at the second shaft end, and
• an external shaft protrusion,
• wherein, at the first shaft end, the shaft forms a trip pin bore perpendicular to its length,
• a spring about the shaft between the external shaft protrusion and the holding protrusion,
• a primer within the firing bore at the second firing bore end,
• a safety nozzle removably attached to the second firing bore end, the safety nozzle comprising a first safety nozzle end, a second safety nozzle end, an internal safety nozzle volume, and external safety nozzle walls, wherein:
• the first safety nozzle end is open and removably connected to the second firing bore end,
• the second safety nozzle end is closed, and
• the external safety nozzle walls form a plurality of apertures, and
• a trip pin configured to be inserted into the trip pin bore of the shaft such that the spring of the firing pin assembly is compressed,
• wherein the spring is configured to decompress in response to removal of the trip pin, thereby causing the firing pin assembly to move within the firing bore towards the second firing bore end until the firing pin strikes the primer causing a primer explosion and the external shaft protrusion interfaces with the internal firing bore protrusion causing the firing pin assembly to stop moving towards the second firing bore end;
• a second support structure;
• and
• a flexible line connected to the second support structure and the trip pin of the perimeter breach warning device such that, the pulling of the flexible line will remove of the trip pin and cause the spring to decompress, causing the firing pin assembly to move within the firing bore towards the second end of the firing bore until the firing pin strikes the primer causing a primer explosion and the external protrusion of the shaft interfaces with the internal protrusion of the firing bore causing the firing pin assembly to stop moving towards the second end of the firing bore.

A method of warning of perimeter breach, the method comprising:

• attaching a perimeter breach warning device to a first solid support structure, the perimeter breach warning device comprising:
• a main body forming a firing bore therethrough, wherein the firing bore comprises a first firing bore end, a second firing bore end, and an internal firing bore protrusion,
• a holding protrusion at the first firing bore end,
• a firing pin assembly within and extending out from the firing bore, the firing pin assembly comprising:
• a shaft comprising a first shaft end and a second shaft end, wherein the shaft comprises:
• a firing pin at the second shaft end, and
• an external shaft protrusion,
• wherein, at the first shaft end, the shaft forms a trip pin bore perpendicular to its length,
• a spring about the shaft between the external shaft protrusion and the holding protrusion,
• a primer within the firing bore at the second firing bore end,
• a safety nozzle removably attached to the second firing bore end, the safety nozzle comprising a first safety nozzle end, a second safety nozzle end, an internal safety nozzle volume, and external safety nozzle walls, wherein:
• the first safety nozzle end is open and removably connected to the second firing bore end,
• the second safety nozzle end is closed, and
• the external safety nozzle walls form a plurality of apertures, and
• a trip pin configured to be inserted into the trip pin bore of the shaft such that the spring of the firing pin assembly is compressed,
• wherein the spring is configured to decompress in response to removal of the trip pin, thereby causing the firing pin assembly to move within the firing bore towards the second firing bore end until the firing pin strikes the primer causing a primer explosion and the external shaft protrusion interfaces with the internal firing bore protrusion causing the firing pin assembly to stop moving towards the second firing bore end;
• connecting the perimeter breach warning device to a second solid support structure with a flexible line,
• wherein, upon a perimeter breach, the flexible line will be pulled and will remove the trip pin and cause the spring to decompress, causing the firing pin assembly to move within the firing bore towards the second end of the firing bore until the firing pin strikes the primer causing a primer explosion and the external protrusion of the shaft interfaces with the internal protrusion of the firing bore causing the firing pin assembly to stop moving towards the second end of the firing bore.
