Firing

The COBRA system is equipped with several types of firing features ranging from basic manual firing to fully automated scripting.  

Firing Mode

COBRA supports professional E-Match, MJG Firewire Initiators, and Talon/Clip-on Igniter Clips. To support both igniter types the module uses a firing mode. The first firing mode is E-Match mode. Ematch mode will fire a pulse of electricity for one-tenth of a second. The other firing mode supported is Talon/Clip-on Igniter mode, which will fire for two seconds. Talon/Clip-on Igniter mode uses a two-second pulse to allow enough time for the Talon/Clip-on Igniter filament to burn into the powder core of the fuse. 

Select the appropriate firing mode based on the igniter being used. 

 


  1. Insert key into the 18R2 key switch and turn clockwise to the ON position to power on the remote.
  2. Insert key into the module key switch and turn to the ARM position to power on the module. 
  3. Allow both the 18R2 and module to complete the startup sequence. The startup sequence is complete when the device displays the channel, for example, “c00".
  4. To change the mode on the firing module:
    • For Talon/Clip-on Igniter Clip mode, press and hold the SYNC button while also pressing the CH+ button until 2.0 is displayed, indicating a two second fire time.
    • For E-Match mode, press and hold the SYNC button while also pressing the CH- button until 0.1 is displayed, indicating a one tenth of a second fire time.
    • After powering off or removing the batteries, the selected mode will be retained by the system.

Manual Firing

Manual (non-scripted) firing is merely pressing buttons to fire the specific cues desired. An operator can navigate modules by pressing the CH+ and CH- buttons on the remote and then pressing buttons 1-18 to fire them instantly. You can place modules on unique channels or on the same channel to shoot at the same time. Manual firing is a straightforward, hands-on experience, perfect for backyard exhibitions.

 


Manual firing allows an operator to use the CH+ and CH- buttons to select specific modules and fire selected cues by pressing the corresponding Cue Button (18).

  1. Press the 18R2 CH+ or CH- button to locate specific module.
  2. Each channel will display cue LED indicator lights for available cues. Green LED lights indicate live product with good continuity.
  3. Press Cue Buttons (1-18) to manually fire the cue. Continue this process through additional cues.
    • The 18R2 has a firing memory. Cues that have not been fired will be green, cues that have fired, red and the blinking red light indicates the last cue fired.
    • The 18R2 will display this information for all modules. Press the CH+ or CH- buttons to scroll through modules for real-time representation of cues that have fired and cues available to fire.
    • If you are running firmware version 6.0 or higher, the module cue will fire for as long as the button is pressed*. If your module is in Talon/Clip-on Igniter mode, the cue will fire for no less than two seconds. If you are running firmware version 5.1 or lower, the module cue will fire for 0.1s if your module is in e-Match mode and two seconds if your module is in Talon/Clip-on Igniter mode. For more information on e-Match and Talon/Clip-On Igniter mode, see What is the difference between e-match and Talon/Clip-on Igniter mode?.

      *The hold to fire functionality is supported on all modules except 18M hardware A versions whereby the module will pulse the cue every 1/10th of a second vs. holding a constant firing pulse.

Basic STEP Firing

Basic STEP firing is used for a simple show where a sequence of cues will be fired from a single module or multiple modules. Basic STEP firing does not support switching between modules or firing multiple modules at the same time as STEP scripting will. 

 


  1. Press the 18R2 CH+ or CH- to locate a specific module to fire.

Note: Each channel will display cue LED indicator lights representing available cues to fire. A green LED light indicates a firing igniter good continuity.

  1. Arm the 18R2, see Arming, Disarming, and Module Count for more information. 
  2. Press the STEP button to fire the first cue on the selected module.
  3. Press STEP again to fire cue number two. Press STEP again to fire cue number three, continuing to press STEP until the final cue or cue number eighteen, the last cue for that module, is fired.
  4. If you are running firmware version 6.0 or higher, the module cue will fire for as long as the button is pressed*. If your module is in Talon/Clip-on Igniter mode, the cue will fire for no less than two seconds. If you are running firmware version 5.1 or lower, the module cue will fire for 0.1s if your module is in e-Match mode and two seconds if your module is in Talon/Clip-on Igniter mode. For more information on e-Match and Talon/Clip-on Igniter mode, see What is the difference between e-match and Talon/Clip-on Igniter mode?.

    The hold to fire functionality is supported on all modules except 18M hardware A versions whereby the module will pulse the cue every 1/10th of a second vs. holding a constant firing pulse.

Note: After the final cue is fired, the 18R2 will automatically increment itself to the next channel. The LED indicator lights will then display cues available to fire on that module.

  1. Continue to press the STEP button until all modules and cues have fired. 

AUTO FIRE Sequencing

AUTO FIRE is a feature that allows the execution of firing sequences with a fixed time delay between each cue. For example, if module one needs to fire cues one through twelve with a half-second delay between each, auto fire can be used to customize the starting and ending cues, as well as the timed delay. Auto fire is not a replacement for full scripting.

 


  1. Insert key into the 18R2 key switch and turn clockwise to ON position to power on the remote.
  2. Allow the 18R2 to complete the startup sequence. The startup sequence is complete when the device displays the channel, for example, “c00". 
  3. Arm the 18R2, see Arming, Disarming, and Module Count for more information. 
  4. Press AUTO FIRE to set the starting cue of the sequence.
    • “S” will display, representing the starting cue.
  5. Select the starting cue number by pressing the corresponding Cue Button (1-18).
    • The starting cue will be displayed as “S01” indicating cue one, for instance.
  6. Press the ending CUE Button (1-18) to set the ending cue for the sequence.
    • The ending cue will be displayed as “E12” indicating the end cue being twelve.
  7. Use the + and/or - buttons to adjust the timing delay from one-tenth of a second (0.1) up to ninety-nine seconds (99) between each cue. The timing delay is shown in the bottom 7 segment display.
  8. To execute the sequence, press the AUTO FIRE button.
    • Holding the AUTO FIRE button throughout the sequence will allow the 18R2 to automatically increment the cues on that channel. 

Note: The starting cue may be higher than the ending cue; the starting cue can be set to twelve and the ending cue set to one. Holding the AUTO FIRE button will increment the channel automatically continuing the AUTO FIRE system the subsequent channels. Pressing AUTO FIRE again will stop the current sequence and will be shown as Stp on the 7-segment display.
