How to stop a particle system from spawning and remove when active particles are dead?

I have a particle system that was created with a SPAWNEMITTERATTACHED Node and it is attached to a socket that i created on the FPS Arms Mesh, on the right hand(Palm). I can’t get the emitter to stop after it spawns how can I deactivate the Emitter? The Emitter is a Beam Type emitter

P.S. I’m new to UE4(been using it for about a month now.)
