Why Elevators Need Access Control Too
When we talk about access control, most people think about doors, swiping a card or unlocking a gate. But entry is only the first step. Once someone is inside the building, the real question becomes: Where can they go next?
Let’s imagine a scenario where someone enters the building with valid access, then uses the elevator to reach a floor they weren’t supposed to access.
That’s the gap.
In modern buildings, elevators are not just a convenience, they act as internal gateways. If they’re not secured, your access control is only doing half the job.
That’s why OptiSpaces by Spintly extends access control beyond doors into secure, controlled movement across the entire building.
Turning Elevators into Access Points
In OptiSpaces by Spintly, an elevator isn’t just treated as hardware, it’s treated exactly like a door, a fully controlled access point. But before any permissions or access rules come into play, there’s an important setup step behind the scenes.
Step 1: Setting It Up (Partner-Level Configuration)
Before admins can assign floor access, the elevator must be configured by a Partner:
This involves:
- Adding the elevator as an Access Point
- Setting the application type to Elevator
- Configuring it as Reader + Channel Extender
This setup connects:
- The elevator reader (where users tap their credential)
- The channel extender boards (which manage signals)
- The floors, mapped through channels
This makes the elevator a fully controllable part of the access control system.
How Floors are Actually Controlled (Board & Channel Mapping)
This is where the system gets a bit technical but also where the real control happens. Behind the scenes, the elevator doesn’t directly “understand” floors. Instead, it works through a mapping structure:
- Each elevator setup can have 1 to 4 boards
- Every board has 16 channels
- Each channel is mapped to one specific floor
So in simple terms: Boards → Channels → Floors
Key Rules You Should Know
- A floor can be mapped to only one board
- Boards are connected in sequence: Reader → Board1 → Board2 → Board3 → Board4
- Physical wiring must match system configuration
- DIP switch settings must align with board numbering
If any of this mapping is incorrect, the system won’t behave as expected.
How Users Actually Access Floors
Now let’s look at how this works in real life, what actually happens when someone steps into an elevator.
Step-by-Step Flow
- User enters the elevator
- Taps their credential on the elevator reader
- System verifies their identity and assigned permissions
- Only the allowed floors light up
- User selects a floor
- Elevator moves
What’s Important Here
- If no one taps → buttons remain inactive
- If no floor is selected → elevator doesn’t move
This ensures every movement is authenticated and controlled. No tap means no access.
Multi-Credential Access (Built for Today, Ready for Tomorrow)
Currently, elevator access is card-based, but the system is designed to go beyond that. It’s built to support multiple credential types as buildings evolve, including:
- Mobile credentials (BLE / NFC)
- QR-based access
- Unified digital identities
What this means is, a single user identity can work seamlessly across doors, elevators, and other systems.
What Happens When Multiple Users Enter the Elevator?
But here’s where it gets interesting: If User 2 taps before User 1 selects a floor
Then:
- User 2’s access overrides User 1
- Only User 2’s permitted floors remain active
What About User 1?
To regain access: User 1 simply needs to tap again after the system resets
Why This Behavior Exists
This follows a simple rule: First-Access-First-Select. The system ensures:
- No mixing of permissions between users
- No confusion on which floors should be active
- Clean, predictable behavior inside the elevator
In short, at any given moment, the elevator responds to one user’s access context.
Wireless + Real-Time Behavior
Even though elevators rely on physical hardware, the actual control sits on the platform which means everything is centrally managed and updated in real time.
So when a user taps their credential:
- The system instantly checks their permissions
- Any recent changes (like updated access or revoked permissions) are applied immediately
- Admins can manage access across multiple buildings from a single system
Changes reflect instantly without manual intervention.
What It Depends On
For the system to function correctly:
- The reader must be online
- The boards must be active
Currently If the devices go offline, the existing permitted users may still access the elevator and use it.
Audit, Logging, and Security
In a system like this, control alone isn’t enough, you also need complete visibility into what’s happening. That’s why every action in the system is recorded. Nothing is missed.
What Gets Tracked
- Access attempts (both granted and denied)
- Permission assignments or changes
- Configuration updates
And most importantly: Logs are immutable, they cannot be modified or deleted
Because of this, the system is:
- Audit-ready: you can trace exactly what happened, when, and by whom
- Compliance-friendly: a complete, reliable history is always available
In simple terms, you’re maintaining a clear record of every action.
What Happens When Elevators Are Not Controlled
Elevators are one of those things most people don’t think twice about when it comes to security but that’s exactly where the problem starts.
Without proper control:
- Users can move to unauthorized floors
- Internal security boundaries start to break down
With OptiSpaces, this gap is closed.
- Every movement is verified
- Every floor is intentionally controlled
- Every action is tracked and logged
Beyond Doors
Access control isn’t just about getting into a building anymore, it’s about how people move within it. What really matters is connecting everything together: who the user is, what they’re allowed to access, and how that translates into real-world movement.
That’s what OptiSpaces by Spintly does.
In a world where buildings are becoming smarter and more connected, access control needs to move beyond doors. It needs to follow the user throughout the entire space quietly, reliably, and without friction.
And that includes the elevator.
