Yes, I'll dig out the info again...

Leaving them armed isn't safe at very low RPM.  They will fire after
1/10 second of being armed whether you tell them to fire or not.

As I recall, over 2.7V on the fire input arms them, then
grounding it fires them.  Ie you don't need much more than
an opto-isolator and a resistor to drive them.
