In Rust, there’s nothing worse than getting raided with your doors wide open. One missed click, one moment of distraction—and everything’s gone. But with this intelligent, expandable automatic door-closing system, that’s no longer a concern. This setup guarantees that when a raid starts, your base responds before you even get the chance to panic. It shuts every door in under a second using either a remote trigger or seismic sensor—and it’s built to handle over 45 doors from a single large battery. Welcome to the future of Rust base security.

What This System Does

The beauty of this design lies in automation and modularity. When the first rocket hits, a seismic sensor detects the impact and sends a pulse that closes every door in your base. Alternatively, you can activate the entire system remotely through your phone using Rust+. This setup uses a smart switch, supports dozens of doors, and consumes very little power. It’s designed to be efficient and highly expandable.

Even better, the system can be modified to include player detection with a heartbeat sensor, ensuring that if anyone tries to deep your base, the entire door network slams shut before they can touch your loot.

Idle State and Power Layout Overview

Let’s walk through how the circuit works in its idle state. Your power source feeds into a battery, and from there, it’s distributed to a set of daisy-chained branches. Each of these branches serves a unique function:

1. First branch powers the door controllers directly.
2. Second branch connects to an AND switch.
3. Third branch connects to the smart switch.
4. Fourth branch powers the timer.
5. Fifth branch feeds the blocker and seismic sensor.

The smart switch activates the system either via your phone or a sensor. When triggered, the smart switch powers the timer. The timer then activates a blocker, creating a short pulse of 0.25 seconds that flows through the AND switch, closing all connected door controllers. The blocker also shuts off the smart switch immediately, giving it the feel of a responsive button rather than a toggle.

Building the Circuit

Start with your power source and battery. Place all necessary electrical deployables like branches, switches, and sensors in the layout. Then:

• Connect your power source to the first branch.
• Daisy chain all other branches together in a row.

For the first two branches (which handle your door controllers), match the count to your number of doors. For instance, six doors mean a setting of six. Now:

• Connect the second branch to input A of the AND switch.
• Connect the third branch to the smart switch, which will act as the main trigger.

Set the branch connected to the smart switch to two power. Treat the top branch here as a splitter and set it to one. Then:

• Run one output to the AND switch’s input B.
• Run another to the timer’s toggle on.

From the timer, wire the output to the blocker’s block input. The blocker prevents the smart switch from remaining on after the pulse is sent. Then:

• From the blocker, wire to the smart switch’s turn off input.
• Finally, from the last branch’s output, connect to the seismic sensor and back to the smart switch’s turn on input.

Set the timer’s interval to 0.25 seconds—this is just enough to close the doors without wasting energy.

Hooking Up the Doors

To hook up doors:

1. Place a branch and door controller next to each door.
2. Set each branch to one.
3. Run power from the main power line to the first door branch, then daisy chain the rest.

If your doors start open, don’t worry—powering the door controllers will open them automatically. It’s normal. Now we set up the close circuit:

• Run power from the AND switch’s output to each door branch.
• Then wire from the branch output to the door controller’s close input.
• Daisy chain all remaining door controllers the same way.

Once everything is in place, verify that the first two branches match your door count. This ensures that power distribution is accurate and that every door closes on command.

Adding Heartbeat Sensor Protection (Anti-Deep Upgrade)

To expand your setup and defend against deepers, add a heartbeat sensor:

1. Place a new branch under the seismic sensor.
2. Connect the previous power into the new branch input.
3. Set the new branch to one.
4. Place an OR switch on top of the seismic sensor.
5. Wire the old sensor output into the OR switch’s output.
6. Connect the seismic sensor to input A and the new heartbeat sensor to input B.
7. Run the last branch output into the heartbeat sensor.

Place the heartbeat sensor in your loot room and configure it to detect unauthorized players only. Now, any time an outsider enters your loot room, the system activates and slams the doors shut. The intruder is left wondering what just happened.

Why This System Matters

This isn’t just about doors—it’s about taking back control. With a build like this, you no longer have to rely on memory or reaction time during a panic raid. Your base protects itself. You can close doors from your phone. You can secure loot automatically when someone tries to deep you. And you can expand this system easily just by adding more branches and controllers as your wipe progresses.

It’s secure, expandable, and efficient. And once you try it, you won’t want to live in a Rust base without it.
