HotShot Electronic Initiation System Components

HotShot Electronic Detonators

• HotShot detonator
• Downline and inter-hole wire
• Male connector
• Female connector

When connecting a blast pattern using HotShot detonators, the HotShot units are connected in the order of firing along a row of holes. The connections are simple; the male connector of one detonator simply snaps into the female connector of the next, and so on, along a row.

HotShot Tagger

The HotShot Tagger is a powerful and blaster-friendly hand-held device that is used to:

• Test individual HotShot detonators
• Test strings of detonators
• Test and troubleshoot the entire installation
• Define hole configuration
• Design the blast, which involves assigning constant delays between boreholes and individual delays between rows, as well as closed chevron stagger delays.

The HotShot Tagger, together with the Blast Cradle and the Blast Key, enables initiation of the blast from a point of safety.

Easy-to-follow Tagger screen menus lead the blaster through all on-bench and firing operations.

HotShot Blast Cradle

The HotShot Blast Cradle is used in conjunction with the Tagger and a Blast Key to initiate the blast.

The Blast Cradle connects to the bench via a 2-wire connection from the outputs of the docked Tagger to the Bench Controller(s) on the blast. In addition, the Blast Cradle is used to charge the Tagger.

HotShot Blast Key

The HotShot Blast Key must be docked in the Blast Cradle for the blast to be armed and fired. The Blast Key houses the electronic components required to generate the blasting voltage and encoded firing signals during the initiation of the blast. For security purposes, Blast Keys are password protected.

The Blast Key incorporates the ARM button (needed to arm the system before blasting) as well as the two FIRE buttons required to fire the blast.

HotShot Bench Controller

The HotShot Bench Controller is placed between the connected blast and the control equipment (Blast Cradle). It interfaces 2-wire communication to 4-wire communication.

 

HotShot Row Controller

The HotShot Row Controller connects rows and indicates the inclusion of a row to the control equipment.

 

HotShot Branch Controller

The HotShot Branch Controller is used to deal with out-of-pattern holes.

 

HotShot End Plug

The HotShot End Plug is placed into all open connectors and indicates the boundaries of the blast to the control equipment
