🚧 Introduction

Extra-Low Voltage (ELV) systems are critical to modern building infrastructure. But mistakes during planning, installation, or maintenance can lead to massive cost overruns, delays, and system failures. Here are the most common ELV mistakes that businesses should avoid—and how to prevent them.

❌ 1. Poor System Design Without End-User Consultation

Skipping end-user input often results in:

• Unnecessary features
• Lack of practical functionality
• User frustration

✅ Solution: Include stakeholders early. Ask: What are the daily pain points? What must the system do?

📉 2. Underestimating Bandwidth & Capacity Requirements

A common oversight in data networks and CCTV setups:

• Using low-speed switches or limited NVR storage
• Poor Wi-Fi coverage

✅ Solution: Design for current and future demand. Factor in 5–10 years of growth.

🧱 3. Not Considering Infrastructure Limitations

Examples:

• Using copper cable runs >90m
• Improper grounding
• No dedicated IT rooms or cable trays

✅ Solution: Perform a site assessment and align ELV design with MEP and civil plans.

📦 4. Mixing Brands and Incompatible Components

Using different brands without verifying compatibility can:

• Break integrations (e.g., ACS + CCTV)
• Void warranties
• Lead to unstable systems

✅ Solution: Stick to a brand ecosystem or confirm cross-compatibility.

🔄 5. No Provision for System Scalability or Upgrades

Businesses grow, but many ELV systems don’t. Mistakes:

• Fixed switch port counts
• Inflexible server/NVR space
• Limited access control zones

✅ Solution: Always design for scalability. Use modular hardware and cloud-ready platforms.

⚠️ 6. Ignoring Fire Stopping and Cable Path Approvals

This leads to:

• Delays in consultant approvals
• Handover rejections
• Fire regulation violations

✅ Solution: Work closely with fire consultants. Document and submit your cable management plans.

🛠️ 7. Using Untrained Technicians or No Commissioning Plan

Improper terminations, poor programming, and undocumented systems can be disastrous.

✅ Solution: Ensure technicians are trained and certified. Use commissioning checklists and log test results.

🕵️ 8. Skipping System Testing & User Training

You may install a great system—but if no one knows how to use it, it’s a failure.

✅ Solution: Schedule:

• Site acceptance tests (SAT)
• Client training sessions
• Maintenance documentation handover

📜 9. Incomplete Documentation

Biggest mistake during project closure:

• No as-built drawings
• No IP address tables
• Missing warranty papers

✅ Solution: Build a handover checklist and complete documentation pack before final invoicing.

💼 10. Focusing Only on Cost, Not on Value

Going with the lowest bidder may mean:

• Cheap materials
• Inexperienced team
• No after-sales support

✅ Solution: Balance cost with quality, support, and experience. A good ELV partner saves money long-term.
