Salient Features

  • Simple user-friendly two wire design

  • Factory Programmed Delay Number and Field Programmable Delay Interval (e-DET)

  • Factory Programmed Delay Interval (e-DET ft)

  • Accurate Delay firing time

  • Special connector for easy field connections

  • Firing sequence can be aborted by the operator any time
    after powering the detonators (e-DET)

  • Detonator does not fire on application of DC current or voltage

  • Detonator requires coded signal from the e-XPLODER to
    initiate firing

LINE

e-XPLODER

e-DET is fired using a special e-XPLODER. The exploder charges individual detonators, transfers the delay interval data to the firing circuit and sends the coded signal to the detonators, to initiate the timing sequence.

  • Operating Voltage: 14V DC (rechargeable battery)

  • Unit-Specific Electronic Authorization Key

  • Portable & User-friendly

  • Alphanumeric 4 Line LCD Display

  • SET, CHARGE, FIRE, ABORT controls

  • Capacity: 150 Detonators

Precautions

  • Do NOT subject e-DET to impact, friction and fire.

  • Do NOT carry out charging of explosives during an approaching storm or when there is lightning activity in the
    blast area. Vacate the blast area and resume operations only after the storm has passed.

  • Do NOT attempt to fight explosive fires.
