Arming & Firing

The COBRA 18R or 18R2 Controller is the device used to fire the 36M or 72M module. The modules can be fired manually by pressing buttons or automatically by scripting with a timing accuracy of 1/100th of a second in firmware version 5.0 or higher and 1/10th of a second in 4.0 or lower.

To arm the 36M or 72M, place the key in the ARM position. Once the startup sequence is complete, the 36M or 72M channel will display the current bank and assigned channel. While only one channel is displayed, your module will fire the appropriate banks and channels regardless if that bank is selected on the module.
To arm the 18R or 18R2, press the ARM button in the lower-left corner of the controller. If you are using the 18R2, the ARM LED will blink and display solid along with the total number of armed devices. Once the 18R2 is armed, the ARM LED will show solid red on the module, meaning you are ready to fire.
For more information on how to fire using the 18R2, see 18R2 Controller User Guide: 18R2 Firing.
