Using the laser trip wires
This is my first time using the fancy switches etc in the DLC. Thanks to some ideas from another thread, I placed the big powered roll up door from the factory across the roadway at Sanctuary. I set a laser tripwire to cut power to it whan triggered by enemies only. That closes the door. Anything that is not hostile will not trigger the tripwire. Carla can come and go with no problem. But, after an enemy triggers the tripwire, it does not reset. You must cycle power to the tripwire to reset it and open the door again. I am looking to see if a non-mod way can cycle the power after some time.

is there a resonable way to do a reset with just vanilla items? I saw one guy trying to explain how to use a pressure plate to do the reset. I do not understand what he did. Does a pressure plate automatically reset after a time?

Also, I want to use the tripwire to trigger a siren a long way away. The siren will lure the settlers to go to the siren instead of running to the attackers. Is conduit the only way to get the power/signal there? How do y'all run conduit a long way in your settlements? Use place anywhere to bury it with some vertical pieces to access?

Conduit or wires, it is the circuit that matters.

I think he used the trip wire to switch something on, then the pressure plate to switch it off. I never really got into the logic circuits.

Check youtube to find out how to set up powered doors. They're not that hard, but can be confusing.

As for the siren triggering from a long distance away, there is a simple mod that enables unlimited length for power lines. It's called .........Puma's Longer Power Lines. I have overhead lines 3 stories high up that span my settlements.

If I may try, what are you attempting to do?

You could place two Laser Tripwires, one on each side; so that the one fires and opens the door, then on the other side, to close it - but if you are using a Powered Door, they only have one control.... Hmmm

Too tired sorry I'll try give ideas another time lol

Yea, I guess I will have to break doen and install that mod. It will make things a lot easier.

I Edited the post to add some more info.

See how on the switches there are multiple wires leaving to different places? Using regular power conduits cause every connected wire to backfeed to other wires. But for some wierd reason bethesda made the power switches prevent backfeeds. So if you use the power switch in place of the conduits you can make some very complex circuitry without having to account for backfeeding.

For example in my pic, Turning on the .308 switch puts power to 3 out of the 6 item hoppers feeds above, But you will notice the 3 conduits above also connect to many other switches and conduits. Basically there is a path to all 6 above in some fashion or another. If you make the connections to normal power conduits turning on the .308 switch would power all 6 hoppers, But since the powered switch conduits prevent backfeeding, The .308 switch only turns on the 3 hoppers required to make .308 ammo.

Probably seems very confusing, But it would make you able to have two seperate circuits controlling your door that only has one input. Probably usefull for resetting the tripwire as well.

Think I know what you are telling me. The wire that will go from the tripwire output to the door and to the siren must not touch any other wire. There cannot be some other power source also going to the siren. But without a mod, conduit is the only way to make a very long wire. Wire alone can only go a short distance. So, even with a wire extending mod the wire (or the conduit) must not connect to any other wires. Unless you use some fancy switching scheme.

Basically yes.

I use the longer powerline mod mentioned above, It has a few different versions for lengths, The longest one will literally stretch across the entire sanctuary settlement, So if you go that route you shouldn't have issues with length.

Here is a screen of what i am trying to do. I need something that is timed for about 30-60 seconds. The wiki is no help to say what can be timed. I can use the logic gates if I get something with a timed delay.

A little hard to see but there is a tripwire 1/2 way into the picket fences path.

If I may, there is an Interval Switch that you can set to Delay before switch to the opposite pole (On or Off, ie. switch ON then wait....then switch OFF then wait....then, etc). It will always be ON or OFF, from 1s up to 10s. .

There is also a Delayed Switch that you can connect a Terminal to (after hooking it up to what you want to affect) and set it for 1/8s up to 10s. Since you want something that 'fires' after about 60secs, then you will have to set up six of these in series, so that each one 'waits 10s then fires, passing on the current to the next' - six times. At the end, set the Gate to toggle (along with the Laser Tripwire), then it will also 'reset itself'.

This is just an idea, of course. I hope it was clear, heh. If it wasn't, let me know and I can set it up and Demo it when I can. GL

Thanks. I found a checkers video on Youtube. Looks like the Delayed Switch will work. The manual button on it made me think that it would not do what I want. But I stink I get it now.

Update: Crud! - I got all the logic gates and delays worked out but I should have done more testing before I started. The vanilla tripwire does not work as expected. Its behavior changes every time you cycle power to it. When you first power it and arm it, it does not pass ouput power untill it is tripped. If you cut power to it then power it again, it does the opposite. It passes output power until it is tripped again, then it stops passing power. Its output logic toggles every time the input power is cycled. :steamsad:
I had to break down and use this mod
Automatic Laser Tripwire

The laser tripwires in F4 are horrible, the only type that resets itself without manual input is for conveyor belts and is really hard to work with in other builds. I've done a few builds with them as detectors for guard posts so the signal changes when a guard is standing on watch or not, it's unreliable in many cases but having the settlement automagically go into lockdown the moment a guard steps off a post to engage a hostile is actually pretty cool. Would be even more cool without broken pathing, random teleporting NPCs, tripwires not working unless the player is really close, random unexplained crashes with no way to find out what happened and so on. Still, it's something.

Thanks. Thats another good idea.

When you're done playing around with trip wires, make some kind of animated sign for your settlement using light boxes. I guarantee it will be much more rewarding than the trip wires and will always work properly. Might take some time to figure out, but I found them to be much more enjoyable than anything I set up using trip wires. Every time I went to that settlement, I'd see the animated sign doing its thing.

With the trip wires they don't always work right, and settlers won't use them to open doors to get into buildings. In fact, if you make a building and put beds in it with only one entryway, and use a tripwire to open the door, the game won't even register those beds until you put in a regular doorway.
