How to Create a Wiring Diagram for Your Access control system design

Creating an effective wiring diagram is a critical step in access control system design and installation. A well-designed wiring diagram provides a clear visual representation of how all the components of your access control system connect and communicate with each other. It serves as the blueprint that guides the physical installation and ensures the system functions as intended.

In today's security-conscious world, a properly designed and installed access control system is essential for protecting people, property, and assets. Whether you're securing a small office or a large corporate campus, a robust access control system helps manage who can enter your facility, when they can enter, and which specific areas they are authorized to access.

However, designing an access control system can be complex, with numerous components, wiring connections, and configuration settings to consider. This is where a detailed wiring diagram becomes invaluable. It helps translate the system design into a physical implementation that installers, technicians, and maintenance personnel can understand and follow.

In this comprehensive guide, we'll walk through the key steps and best practices for creating a professional wiring diagram for your access control system design and installation. We'll cover everything from the basic components and symbols to use, to more advanced topics like AV system integration and compliance considerations. By the end, you'll have the knowledge and tools to create effective wiring diagrams that streamline your access control deployments.

But first, let's discuss why having a quality wiring diagram is so important for the success of your access control system design and installation.

The Importance of a Well-Designed Wiring Diagram

A wiring diagram is not just a simple drawing - it's a critical component of your overall access control system design and deployment strategy. Here are some key reasons why investing time to create a professional wiring diagram is well worth the effort:

1. It Provides a Clear System Overview

An access control system often consists of multiple components spread across different parts of a building or campus. This can include card readers, door controllers, electric locks, request-to-exit sensors, door position switches, power supplies, and more. A wiring diagram brings all these pieces together into a unified visual overview.

By showing how each device connects to the others, and how they all tie back to the central control panel, a wiring diagram provides a bird's-eye view of the complete system. This makes it easier to understand the system architecture, identify potential bottlenecks or points of failure, and communicate the design to stakeholders.

2. It Guides the Physical Installation

A wiring diagram is the roadmap that installers and technicians follow to physically deploy the access control system. It shows them exactly which wires need to be run, how they should be labeled, and where they terminate at each end.

Without a clear diagram to follow, installers may make incorrect connections, use the wrong cable types, or route wires inefficiently. This can lead to system malfunctions, performance issues, and costly rework. A quality wiring diagram helps ensure the installation is done right the first time.

3. It Simplifies Troubleshooting and Maintenance

Even the best access control systems can experience issues over time. Devices may fail, wires may come loose, or configurations may need updating. When problems arise, a wiring diagram is an invaluable troubleshooting tool.

By tracing wires and connections on the diagram, technicians can quickly isolate where a fault may lie, without having to physically trace wires through walls and ceilings. The diagram also provides a reference for proper wire colors, labels, and terminations, ensuring repairs are done correctly.

For ongoing maintenance, the wiring diagram serves as the go-to documentation for the system. It can be used to plan system expansions, guide component replacements, and train new personnel on the system architecture.

4. It Supports Compliance and Documentation

Many facilities, especially in regulated industries like healthcare, finance, and government, must comply with strict security standards. These may include requirements for how access control systems are designed, installed, and documented.

A professional wiring diagram helps meet these compliance requirements by providing a detailed record of the system architecture. It can be used to validate proper wiring practices, demonstrate network segmentation, and show the locations of critical security devices.

Having an accurate, up-to-date wiring diagram also simplifies the documentation process for security audits and certifications. It provides a single source of truth that can be referenced by auditors, regulators, and other stakeholders.

5. It Enables Collaboration and Knowledge Sharing

Designing and deploying an access control system often involves multiple stakeholders, including security consultants, IT staff, facilities personnel, and third-party integrators. A wiring diagram serves as a common language that allows all these parties to collaborate effectively.

The diagram can be used in design reviews, installation planning meetings, and training sessions to ensure everyone has a shared understanding of the system. It also helps preserve institutional knowledge about the system, reducing dependence on any single individual.

Now that we understand the importance of a well-designed wiring diagram, let's dive into the specifics of how to create one. We'll start by looking at the key components and symbols you'll need to include.

Essential Components and Symbols

An access control system wiring diagram uses a set of standard components and symbols to represent the various devices and connections in the system. While the exact symbols may vary slightly based on the diagramming software or template you use, the core elements are generally the same.

Here are the key components and symbols to include in your access control system wiring diagram:

1. Access Control Panel

The access control panel is the brain of the system. It's the central device that manages all the other components, makes access decisions, and logs events. On a wiring diagram, the panel is typically shown as a large rectangle with its make and model number clearly labeled.

The panel will have several wiring terminals or connection points for power, network, and peripheral devices. These should be clearly labeled on the diagram, often using the manufacturer's terminal naming conventions (e.g. "DC+", "DC-", "D0", "D1", etc.).

2. Card Readers

Card readers are the devices that capture credential information from users, such as by reading an RFID card or key fob. On a diagram, card readers are typically shown as small rectangles, with lines indicating their wiring connections back to the control panel.

Be sure to label each reader with a unique identifier (e.g. "Reader 1", "Front Door Reader", etc.) and indicate its location on the diagram relative to the door it controls. If the reader has additional features like a keypad or biometric sensor, these should also be noted.

3. Electric Locks

Electric locks are used to physically secure doors and gates. They are controlled by the access control system, which can lock or unlock them based on valid credentials and schedules. On a diagram, electric locks are often shown as rectangles with a key symbol inside.

There are several types of electric locks, including magnetic locks, strike locks, and bolt locks. Be sure to specify the lock type for each door on the diagram, along with its power requirements and fail-safe/fail-secure configuration.

4. Door Contacts

Door contacts, also known as door position switches, are used to detect whether a door is open or closed. They provide valuable input to the access control system for monitoring and alarm purposes. On a diagram, door contacts are typically shown as two small rectangles side-by-side, representing the two parts of the switch.

Indicate on the diagram where the door contact is located on each door (e.g. top, edge, hinge side, etc.) and how it is wired back to the control panel. Some door contacts also include a REX (request-to-exit) button, which should also be noted.

5. Request-to-Exit (REX) Devices

REX devices allow people to exit through a controlled door without needing to use their credential. The most common type is a motion sensor that detects when someone is approaching the door from the inside. Other types include push buttons, bars, and emergency break glass.

On a diagram, REX devices are typically shown as a rectangle with a motion or button symbol inside. They should be clearly labeled and their location and orientation relative to the door should be shown.

6. Power Supplies

All the devices in an access control system need power to function. Typically, there will be one or more centralized power supplies that provide low-voltage DC power to the control panel, as well as to peripheral devices like locks and REXs.

On the diagram, power supplies should be shown as rectangles with their voltage and amperage ratings clearly labeled. The wiring connections from the power supply to each device should be shown, using the appropriate wire gauge and color coding.

7. Network Connections

Modern access control systems are often IP-based, meaning they communicate over a network using Ethernet or Wi-Fi. The network architecture should be clearly shown on the diagram, including all switches, routers, and cabling.

Use standard network symbols like a cloud for the overall network, rectangles for switches and patch panels, and lines with RJ45 connectors for Ethernet cables. Be sure to label all network devices and indicate network addresses and VLAN configurations where applicable.

8. Wiring and Cabling

The wiring and cabling are what tie the whole system together. On the diagram, each wire should be represented by a line, with different colors or patterns used to distinguish different wire types (e.g. solid red for power, dashed green for data, etc.).

Label each wire with its gauge, conductor count, and function. For example, "18/4 shielded, reader to panel" would indicate an 18-gauge, 4-conductor shielded cable running from a card reader to the control panel.

Use arrows and other annotations to clearly show the direction of data flow and the termination points for each wire. Wherever possible, use standard wiring color codes (e.g. red/black for DC power, green/white/black for Wiegand data, etc.).

By including these core components and symbols, and using clear labeling and annotations, your access control system wiring diagram will provide a complete and unambiguous representation of the physical system architecture.

In the next section, we'll look at some best practices for laying out the diagram and making it easy to follow.

Diagram Layout and Organization

With the key components and symbols defined, the next step is to lay out the wiring diagram in a way that is clear, organized, and easy to follow. Here are some best practices to keep in mind:

1. Use a Logical Flow

The diagram should flow in a logical manner, typically from left to right and top to bottom. Start with the main components like the control panel and power supplies on the left side of the page, and then show the peripheral devices branching out to the right.

Group related components together, such as all the devices associated with a particular door (reader, lock, REX, door contact). Use spacing and alignment to make the groupings clear.

2. Provide a Legend

Include a legend or key that explains all the symbols, colors, and annotations used in the diagram. This should be positioned at the bottom or on a separate page, where it can be easily referenced.

The legend should include items like:

Component symbols and their meanings

Wire colors and types

Connector and termination symbols

Any custom or project-specific annotations

3. Use a Grid and Rulers

Most diagramming software includes tools for creating a grid and rulers on the page. Use these to ensure proper alignment and spacing of components.

The grid doesn't need to be visible on the final printed diagram, but it helps keep things tidy and professional-looking during the creation process. Aim for a consistent spacing between components, such as 0.5" or 1" increments.

4. Label Everything Clearly

Each component, wire, and connection point should be labeled clearly and unambiguously. Use a consistent labeling scheme throughout the diagram.

For example, you might label card readers as "CR-1", "CR-2", etc., and door locks as "DL-1", "DL-2", etc. Wires can be labeled with their function and endpoint, such as "CR-1 PWR" for the power wire to card reader 1.

Avoid using generic labels like "Reader" or "Lock", as these can be ambiguous in larger systems. Always use unique identifiers.

5. Show Door and Room Numbers

Include the actual door numbers and room names/numbers on the diagram. This helps cross-reference the diagram with the physical building layout.

For each door, show its number (e.g. "Door 101", "Door A-35") and the room or area it leads to (e.g. "Main Lobby", "Server Room"). If the door has a specific function or security level, note that as well (e.g. "Emergency Exit", "High Security Area").

6. Use Notes and Call-Outs

Include notes and call-outs on the diagram to provide additional context or explanation where needed. These can be used to:

Specify part numbers or model numbers for components

Provide installation notes or special instructions

Call out specific configuration settings

Highlight any deviations from standard wiring practices

Use a consistent format for notes, such as a box with a dashed outline. Position the notes close to the relevant component or area of the diagram.

7. Provide an Overview and Detail Views

For larger or more complex systems, it can be helpful to provide both an overview diagram and detailed views of specific subsystems.

The overview diagram shows the high-level system architecture, major components, and interconnections. Detailed views then dive into the specifics of each subsystem, such as a single door or floor.

Use clear page numbers and cross-references to link the overview and detail views. For example, the overview diagram might have a note saying "See Page 2 for Door 101 details", and the detail view on Page 2 would be titled "Door 101 Wiring Detail".

8. Use a Template

Consider creating a standard template for your access control wiring diagrams. This can include pre-defined symbols, page layouts, title blocks, and legends.

Using a consistent template across projects helps streamline the diagramming process and ensures a professional, standardized look and feel. It also makes the diagrams easier for others to interpret, as they will be familiar with the layout and conventions.

Many diagramming software packages include pre-built templates for various types of wiring diagrams. These can be a good starting point, which you can then customize to your specific needs.

By following these layout and organization best practices, your access control system wiring diagrams will be clear, comprehensive, and easy for installers and maintainers to follow.

In the next section, we'll look at some specific considerations and best practices for IP-based access control systems.

Diagramming IP-Based Access Control Systems

IP-based access control systems, which use Ethernet networks for communication, are becoming increasingly common. They offer several advantages over traditional hardwired systems, including easier scalability, remote management, and integration with other IP-based security systems like video surveillance.

However, IP-based systems also introduce some additional complexity when it comes to wiring and diagramming. Here are some key considerations and best practices to keep in mind:

1. Show the Network Topology

In addition to showing the access control devices and their wiring, the diagram should also clearly depict the network topology. This includes:

The overall network architecture (e.g. star, mesh, etc.)

The location and interconnection of switches, routers, and other network devices

The IP address scheme and VLAN configuration

Any network security devices or features (e.g. firewalls, VPNs)

Use standard network diagramming conventions, such as cloud symbols for the Internet and WAN links, and rectangles for switches and routers. Show the wired connections between devices using solid lines, and any wireless links using dashed lines.

2. Specify Cable Types and Lengths

For IP-based systems, the type and length of Ethernet cabling is critical. The diagram should specify the cable type (e.g. Cat5e, Cat6), the maximum cable length for each run, and any special considerations like plenum-rated or outdoor-rated cable.

Use cable length calculations and the manufacturer's guidelines to ensure the cable runs do not exceed the maximum supported distances for the chosen cable type and network speed. For example, Cat6 cable has a maximum length of 100 meters for Gigabit Ethernet.

3. Show Power over Ethernet (PoE)

Many IP-based access control devices, such as IP readers and electric strikes, can be powered using Power over Ethernet (PoE). This eliminates the need for separate power supplies and wiring.

On the diagram, clearly indicate which devices are PoE-powered, and the type of PoE being used (e.g. IEEE 802.3af, IEEE 802.3at). Show the PoE connections using the appropriate cable type and pinout (e.g. Cat5e with 4-pair PoE).

Be sure to calculate the total PoE power draw of the devices and ensure the PoE switch or injector can supply sufficient power. Use the manufacturer's guidelines and consider any voltage drop over the cable length.

4. Indicate Network Ports and Addresses

For each IP-based device, indicate the network port(s) being used and the assigned IP address and/or hostname. This is especially important for devices with multiple ports, like IP cameras with a dedicated port for access control integration.

Use a logical and consistent IP addressing scheme, and consider using DHCP reservations or static addresses for critical devices. Indicate the subnet mask, default gateway, and any other relevant network settings.

5. Show VLANs and Network Segmentation

If the access control system is sharing a network with other systems or traffic, it's a good idea to use VLANs to logically separate the access control traffic. This can improve security and performance.

On the diagram, show the VLAN configuration, including the VLAN numbers and names for each segment (e.g. "VLAN 10 - Access Control"). Use different colors or line types to distinguish the VLANs on the diagram.

If the access control system is using a dedicated network, indicate this on the diagram and show how it connects to the wider corporate network, if applicable. Use firewalls or other security devices at the boundary points.

6. Provide Network Details for Wireless Devices

For wireless devices like WiFi locks or mobile credential readers, provide additional details on the wireless network configuration, such as:

WiFi SSID and security type (e.g. WPA2-PSK)

Wireless channel and frequency band

Antenna type and placement

Expected wireless coverage area

Show the location of wireless access points on the diagram, and indicate which devices connect to each one. Use dashed lines to show the wireless connections, and provide the SSID and security key on the diagram or in an accompanying legend.

7. Indicate Remote Connections

IP-based access control systems often support remote connections for administration, monitoring, and integration with other systems. The diagram should show any remote connection points and the methods used to secure those connections.

For example, if the system can be managed via a web browser, indicate the HTTPS URL and any authentication requirements. If there are dedicated VPN connections for remote support or integration with a central security operations center, show those as well.

Use standard security icons like a padlock to indicate secure connections, and provide details on the encryption and authentication methods used.

8. Show Integration Points

One of the key benefits of IP-based access control is the ability to integrate with other systems like video surveillance, intrusion detection, and visitor management. The diagram should clearly show these integration points and the methods used to connect the systems.

For example, if the access control system is integrated with IP cameras for video verification of access events, show the connection between the access control panel and the video management system. Indicate whether it's a direct network connection, or if it goes through a middleware platform.

Use standard arrows and connector symbols to show the direction and type of data flow between systems. Provide details on the integration protocols and APIs used, such as ONVIF, RESTful, or proprietary interfaces.

By following these best practices for diagramming IP-based access control systems, you'll create wiring diagrams that are comprehensive, accurate, and easy to follow. They will serve as an essential reference for deploying, troubleshooting, and maintaining the system over its lifetime.

Compliance Considerations

When designing and diagramming an access control system, it's important to keep in mind any relevant compliance requirements or industry standards. These can vary depending on the type of facility, the sensitivity of the areas being secured, and the specific regulations that apply.

Provide door-by-door wiring details and label each component with its installed location

Include a legend that explains all the symbols, colors, and abbreviations

Use page numbers and cross-references to link overview and detail views

Export the diagram in a format that's easy to view on a mobile device or tablet

Consider creating a separate "installer view" of the diagram that focuses on the physical layout and wiring details, rather than the logical system architecture.

4. What are some common mistakes to avoid when creating access control diagrams?

Some of the most common mistakes to watch out for include:

Forgetting to include all the necessary components, such as door contacts or REX devices

Using inconsistent or unclear naming conventions for devices and wires

Omitting key details like wire gauge, device part numbers, or IP addresses

Failing to show the physical locations of devices relative to the doors and rooms

Not leaving enough space for technicians to make notes or mark up the diagram during installation

Neglecting to update the diagram as changes are made during installation or commissioning

By being aware of these pitfalls and using a methodical, detail-oriented approach, you can create diagrams that are accurate, complete, and easy to follow.

5. How can I keep my diagrams up-to-date over the life of the system?

An access control system diagram is not a static document, but a living representation of the system that should evolve as the system does. To keep your diagrams current:

Use a version control system or change log to track revisions over time

Establish a process for installers and technicians to submit as-built updates and corrections

Schedule regular audits to verify the accuracy of the diagram against the physical installation

Make updates whenever there are changes to the system configuration, devices, or wiring

Distribute updated diagrams to all stakeholders, including the end user, integrator, and service provider

X-DRAW's cloud-based platform and real-time collaboration features make it easy to keep diagrams up-to-date and ensure that everyone is working from the latest version.
