Quick Rocket Automation Question

[hypoeffort]

Finally got the lag playable enough in space to get a good set of rockets going.  I am running a simple not gate setup for the bunker doors for detection and a filter gate with 40 seconds on the activation launch for the rockets.

 

Under my rocket engines I have 2 blast doors that I have on an automation switch.   I want to put in 2 overrides where they will close on the launch and upon rocket retrieval so I do not forget.    Is there any way to send just 1 signal down the line from 3 different directions and each one has the power to override the other two?  I like having the manual access as well as some safety in there.

And gates Or gates/XOr gates dont seem to work for me at the moment.  Memory toggle somehow?

Just wires connected together act as an OR

Not really. Green signal overrides the red, which makes adding an OR gate unnecessary in simple cases, but plain connected wires will propagate the green signal back on the inputs, which is bad if you need to use the same input in multiple places.

What do you mean by don't seem to work? If you want to close the doors, you need a red signal. That can be overridden via an AND gate, that is, if any of the inputs receive a red signal, the output will be red. For two overrides, connect the first output to a second AND gate together with the second override.

Running them through AND gates first eliminates that.

This is actually called a "wired OR" in electronics. The whole wire is the output and the input(s) at the same time. If you need to prevent that, you need to use a gate to decouple this, for example and AND or OR with inputs wired together or two inverters in series.
