An arrangement used in safing and arming a munition fuze includes a light sensor, a magnet, and a circuit composed of an inductor coil, a storage capacitor, and a photosensitive device. The light sensor is a fiber optic cable which responds to a flash of light generated by burning propellant of the munition by receiving and guiding the light energy to the photosensitive device. The magnet responds to setback of a projectile of the munition to move relative to the coil and generate an electrical voltage. The photosensitive device connected to the inductor coil responds to the voltage generated and to receipt of light energy from the light sensor by conducting electrical energy. An electro-explosive actuator connected to the photosensitive device is operable in response to conducting of electrical energy to actuate a rotor of the munition fuze from an unarmed condition to an armed condition. The electro-explosive actuator is thus incapable of actuating the fuze rotor from the unarmed condition to armed condition without both the setback force and burning of the propellant occurring first.
