ABSTRACT:
An apparatus is provided for monitoring the operability of at least a pair of pyrotechnic transmission lines connected to an actuatable safety device. The apparatus includes a conduit in the form of an optical fiber, which extends through one pyurotechnic transmission line, through the actuatable safety device, and through the other pyrotechnic transmission line. One end of the conduit is coupled to a signal source for receiving a signal from the signal source. The signal is directed through the conduit. A sensor coupled at the other end of the conduit senses receipt of the signal directed through the conduit. If the sensor senses the signal directed through the conduit has decreased to or below a predetermined level, then an indicator operates to warn of a break or interruption in at least one of the pyrotechnic transmission lines.
