Abstract : 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 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. (Patents).
