Check Continuity

Checking continuity ensures that the connection between the igniter and the cue on the module is strong and the pyrotechnic product will fire. You can check continuity directly on the module or by using the 18R.

Check Continuity Using the 18R 

Using the CH+ or CH- button on the 18R will toggle between modules allowing testing for continuity on each individual module for the selected channel.

1. Select the CH+ or CH- button to reflect the desired module to be tested.
2. The 18R displays a green LED indicator light for all cues with good continuity that are wired to the module assigned to the channel selected on the controller.

Check Continuity across Multiple Modules on the Same Channel 

The COBRA firing system allows multiple modules to be set to the same channel. This is beneficial for manually fired shows with modules firing at the same time from multiple positions.

1. Pressing the CH+ or CH- buttons will switch between channels, showing the continuity for the module or modules assigned to that channel. 
2. If there are two modules with different cues wired, the 18R will show a solid green LED indicator light for each cue. If there are multiple modules on the same channel with mixed continuity, the 18R will display a flashing green cue LED to indicate that one of the multiple modules on that channel does not have continuity.
3. To differentiate between multiple modules on the same channel, the controller assigns a unique address to each module during the sync process. To see the address, press and release the TEST button on the module and the address will display. Each module will display a unique address. On the 18R, repeatedly pressing the TEST button will cause it to cycle back and forth between the modules, showing the address and the continuity for each.
