How many e-match/MJG initiators/Talons/Clip-on Igniters can I fire in series or in parallel?

When designing your display it is important to take into account the firing maximums of your COBRA module. The maximum of igniters your module can fire depends on the type of igniters, the power source used, and the length of shoot wire or slat cables used.

The following chart outlines the max fire of the COBRA 18M firing module when the igniters are connected directly to the module itself.

For additional information on the number of igniters that can be fired at length please reach out to for support.

Maximum # of Igniters by Power Source

*COBRA only recommends the Energizer 9V battery brand
