A unique signal, safe and arming device for preventing the inadvertent detonation of an ordnance, having an initiator barrier disk and an ignitor barrier disk situated adjacent respective opposite open ends of at least one transfer tube containing an initiator therein. The barrier disks are interconnected to move in synchronism with each other from a first position blocking the ends of the transfer tube to a second position unblocking the ends of the transfer tube. A maze-like slot is located within the ignitor barrier disk and a peg operably engages the maze-like slot. While the ignitor barrier disk moves from its first position to its second position under the control of preselected signals, the peg moves radially within the slot also under the control of preselected signals. This arrangement requires the proper input signals for the appropriate movement of both the peg and ignitor barrier disk in order to permit activation of the initiator to take place. In addition, a monitoring system is included in order to constantly monitor the movement of the disks and the positioning of the peg.

A unique signal, safe and arm device, comprising: a housing; at least one initiator; means situated within said housing for containing said initiator, said initiator containing means having a first open end and a second open end; means positioned adjacent said first open end of said initiator containing means for activating said initiator; an initiator barrier means interposed between said activating means and said first open end of said initiator containing means for preselectively moving between a first position preventing said activating means from activating said initiator and a second position permitting said activating means to activate said initiator; means operably interconnected to said initiator barrier means for permitting preselected movement thereof to take place between said first and said second positions, said preselected movement permitting means including a surface having a uniquely designed pattern of preselected configuration therein, means for operably engaging said pattern along the entire configuration thereof and means for positioning said engaging means with respect to said pattern upon the receipt of appropriate preselected signals; and means operably connected to said initiator barrier means for preselectively moving said initiator barrier means between said first and said second positions upon the receipt of appropriate preselected signals; whereby operable engagement of said engaging means along said entire pattern configuration during movement of said initiator barrier means enables said initiator barrier means to move from said first position to said second position in order to effect activation of said initiator by said activating means.
