A pyrotechnic training system includes a firing block assembly housed in a first container, a pressure-armed trigger module having two triggers housed in a second container, and a power pack/switch system that connects the firing block assembly and triggers. The first and second containers are remote from each other, and may be made from common objects that might be found in combat zones. Quick-release pins inserted through components of the firing block prevents their separation by exploding ordinance within the firing block, maintaining close electrical contacts within the firing block. The pressure-armed triggers employ a mechanical system that energizes an electrical circuit when pressure is released. Such triggers are arranged such that opening or moving the container triggers an explosion at the remote firing block assembly.

1. A pressure-armed trigger system, comprising a frame having a first member at a first end of said frame, a second member at a second end of said frame, said first and second ends being opposite each other, and a third member extending from said first member to said second member, said first, second and third members defining a recess in said frame, said first and second members having respective first and second bores therethrough, said first and second bores opening into said recess, said respective first and second bores having respective first and second longitudinal axes, said respective first and second longitudinal axes being substantially parallel to each other; a first electrical circuit having a first electrical switch therein, said first electrical switch having a first actuator movable between a first position in which said first electrical circuit is open and a second position in which said first electrical circuit is closed, said first actuator being biased to said first position such that said first electrical switch is normally open;a first lever in the recess of said frame and proximate said first member, said first lever having first and second ends opposite each other and a first pivot pin adjacent said third member and between said first and second ends of said first lever, said first lever pivotable about said pivot pin between a first position and second position, wherein said first lever, said first pivot pin, and said first actuator are arranged such that, in said first position of said first lever, said first actuator is in its first position, and, in said second position of said first lever, said second end of said first lever presses upon said first actuator such that said first actuator is in its second position;a first rod residing in said first bore and reversibly movable therein along the first longitudinal axis, said first rod having a first end external to said frame and a second end opposite said first end of said rod and residing within said recess of said frame, said first lever rotatably connected to said second end of said first rod at a location between said first pivot pin and one of said ends of said first lever;a first helical spring having first and second ends opposite each other, said first end of said first spring adjacent said first member of said frame, with said first rod residing in the interior of said first spring and movable therein along the first longitudinal axis;a first collar affixed to said first rod and adjacent said second end of said first spring, said first rod, said first collar, said first spring and said first lever being arranged such that applying pressure to said first end of said first rod along the first longitudinal axis moves said first rod so as to compress said first spring and move said first lever to its said first position, and removing the pressure from said first end of said first rod allows said first spring to expand thus moving said first rod so as to move said first lever to its said second position;a second electrical circuit having a second electrical switch therein, said second electrical switch having a second actuator movable between a third position in which said second electrical circuit is open and a fourth position in which said second electrical circuit is closed, said second actuator being biased to said third position such that said second electrical switch is normally open;a second lever in said recess of said frame and proximate said second member, said second lever having third and fourth ends opposite each other and a second pivot pin adjacent said third member and between said third and fourth ends of said second lever, said second lever pivotable about said second pivot pin between a third position and fourth position, wherein said second lever, said second pivot pin, and said second actuator are arranged such that, in said third position of said second lever, said second actuator is in its first position, and, in said fourth position of said second lever, said fourth end of said second lever presses upon said second actuator such that said second actuator is in its fourth position;a second rod residing in said second bore and reversibly movable therein along the second longitudinal axis, said second rod having a third end external to said frame and a fourth end opposite said third end of said rod and residing within said recess of said frame, said second lever rotatably connected to said fourth end of said second rod at a location between said second pivot pin and said third end of said second lever;a second helical spring having third and fourth ends opposite each other, said third end of said second spring adjacent said second member of said frame, with said second rod residing in the interior of said second spring and movable therein along the second longitudinal axis;a second collar affixed to said second rod and adjacent said fourth end of said second spring, said second rod, said second collar, said second spring and said second lever being arranged such that applying pressure to said third end of said second rod along the second longitudinal axis moves said second rod so as to compress said second spring and move said second lever to its said third position, and removing the pressure from said third end of said second rod allows said second spring to expand thus moving said first rod so as to move said first lever to its said second position. 2. The trigger system of claim 1, further comprising a container having a first portion and a second portion adjacent each other so as to define an interior of said container, wherein said frame is secured within said second portion such said first portion applies pressure to said first end of said first rod such that said first lever is in its first position with said second portion resting on a surface. 3. The trigger system of claim 2, said second portion defining an opening opposite said first portion, said opening accessible to said third end of said second rod such that said third end of said second rod extends therethrough such that, with said second portion of said container resting on a surface, said surface applies pressure to said third end of said second rod such that said second lever is in its third position. 4. The trigger system of claim 1, further comprising first and second stop posts in said recess of said frame, said first stop pin arranged so that said first end of the said first lever rests on said first stop post when said first lever is in its first position, and said second stop post arranged so that said third end of said second lever rests on said second stop post when said second lever is in its third position. 5. The trigger system of claim 1, wherein said second end of said first lever includes a first cam arranged so that, when said first lever is in its second position, said first cam presses upon said first actuator, and said fourth end of said second lever includes a second cam arranged so that, when said second lever is in its fourth position, said second cam presses upon said second actuator.
