Logic gates, Sirens and Delayed power switch

[MadGax]

So I am trying to set up a siren, switched on at the siren, that will run for 30 seconds and then shut off.
Here is the setup I assumed would work.


However when i power on the siren, the delay switch is never activated.
If I disconnect the delay switch from the XOR gate the delay switch will work.
If I attach it to the Stationary gun it work work as expected.

I attached power starting at the generator and worked my way around back to the logic gate. Also tried it in reverse order and still the same outcome.
If I put a power pylon between the delay switch and the XOR gate, the delay switch does appear to operate but the gate never reads the power from the second line.
Lights, terminals, and the stationary gun seems to know power is there, but the logic gate does not.

As you can see, my current workaround uses a stationary gun to destroy the generator to shut off the power, less than ideal.

Anyone got any tips?

If this is to alert Settlers of danger/raiders you will need something triggered at the various spawn points (laser tripwire, automated preferred, could be from a mod). Once tripped would sent power to your siren once for 30 seconds then shut down, though you would need something to reset that action. The Schooledzone has some good "no mods shop class" tips videos on YouTube, so check there as Paul has done a lot with the contraptions DLC and goes over how a lot of that works.
