On top of that, firing order.
Simple.
If you press the Agent 1 button then Bottle 1's squib will fire.
If you press the Agent 2 button then Bottle 2's squib will fire.
There is no link to stop you firing No 2 first but SOP is to fire No 1 Agent then wait 30 secs and if you still have the fire warning fire No 2 Agent.
Hope this helps
