Slave Modules
There are different type of slave modules, however, the most common are "box" type and "rail" type. Box type is pretty self
explanitory, being a small box with cue terminals. See pictures below. The box is good for groups of mortars, or
a group of low level devices such as cakes. A rail type can be a hardwood or fiberglass rail, with cue terminals a measured
distance apart. Another "rail" type is a "slave cable". A standard rail has hardmounted cue terminals that might make it
difficult when spacing between different size mortars varies. A slave cable will have extreme flexibility when it comes to
placement of fireworks, and will potentially save a whole lot of "zip" wire used to extend electric match leads to a cue terminal.
A typical slave module will consist of these main parts:
Cue Terminals
Each slave module will have a number of cue terminals, the number depending on the firing system design. Each terminal is
typically a stereo speaker type of connector with a red and black terminal. There are a few other variations of cue terminals;
however, this also depends on the firing system design. The electric match attached to the firework plugs directly into these terminals.
Firing Cable Interface
The interface can consist of just a loose cable end hanging out of the firing control module, or more commonly, a connector
which sits flush on the slave module, very similar to the firing module. See picture below.
Ground Terminals
You will typically have a simple screw terminal which a ground wire will attach. Some firing systems are internally grounded
through the firing cables and do not require this extra ground line.
