  • Apparatus for locating failures in detonation devices
    Patent number: 5721493
    Abstract: A method is provided for locating failures in a sequentially arranged chain of detonation devices. The method comprises initiating a test signal and passing this signal sequentially along the chain from each correctly operating detonation device to the next after a predetermined delay at each device; monitoring the chain of detonation devices by receiving a confirmation signal from each correctly operating device which has received the test signal; and ascertaining the last device to have received the test signal by a cumulative count of the number of detonation devices which have received the test signal.
