Installing an access control system isn't a weekend DIY project—it's a multi-step process that typically takes 2–6 weeks from planning to full operation. Understanding the timeline and what happens at each stage helps you budget, prepare your team, and avoid costly delays.
Planning & Assessment Phase (1–2 Weeks)
Before any equipment arrives, you'll need a thorough site assessment. A qualified installer visits your property to map entry points, identify wiring routes, check electrical capacity, and understand your security goals. They'll ask critical questions: How many doors need control? Do you want card readers, biometric scanners, or mobile access? What's your budget?
During this phase, expect to provide floor plans and discuss integration with existing systems (alarms, cameras, intercoms). The installer will also check building codes and fire safety requirements—access control can't obstruct emergency egress. This assessment typically costs $300–$800 and is essential for an accurate quote.
Design & Proposal (1 Week)
Once the assessment is complete, the installer designs a system tailored to your layout and needs. A typical proposal includes:
- Controller units and server hardware
- Card readers, keypads, or biometric devices at each access point
- Wiring and conduit requirements
- Software licensing and user management tools
- Installation labor and timeline
Expect proposals to range from $5,000 for a small single-door system to $50,000+ for a multi-building enterprise setup. Don't compare quotes on price alone—verify the hardware quality, software features, and warranty terms. Mercoly lets you gather and compare multiple proposals from trusted Access Control Systems providers side-by-side, making it easier to spot differences in scope and value.
Hardware Procurement (1–3 Weeks)
After you approve the design, the installer orders components. Lead times depend on equipment availability and demand. Standard readers and controllers ship in 5–7 days, but custom or high-volume biometric systems can take 2–3 weeks. Some installers keep stock on-site to speed deployment.
Ask your installer about equipment sourcing upfront. If they use reputable manufacturers (like Salto, Axis, HID, or Genetec), replacements and support are easier down the line. Cheap off-brand readers often cause compatibility issues and leave you stranded when failures occur.
Pre-Installation Preparation (2–5 Days)
Before work begins, coordinate with your team. The installer will need:
- Access to all areas where readers and controllers will be installed
- Temporary power for tools and equipment
- A clean workspace to stage materials
- IT network access for server setup (if cloud-based)
If you're retrofitting an existing building, notify occupants of any disruptions. Running conduit through walls or ceilings may require drilling, cutting, and dust—schedule this outside peak business hours if possible. Ensure parking is available for the installation crew and their van.
Installation & Wiring (3–10 Days)
This is the most labor-intensive phase. Installers mount readers, run cabling, connect controllers, and wire power supplies. A simple 4-door retrofit might take 2–3 days; a 50-door office expansion typically needs a week.
Typical tasks include:
- Mounting card readers or biometric devices at entry points
- Running conduit and low-voltage cabling (often through existing cable trays or new conduit)
- Installing controllers in secure, temperature-controlled cabinets
- Connecting readers to controllers via Ethernet or proprietary cabling
- Testing each reader for proper function and communication
Work closely with the installer on cable routes—poor planning leads to pinched wires, interference, and callbacks. If your building has older infrastructure, the installer may discover issues (corroded conduit, missing neutral grounds) that require rework.
Configuration & Testing (3–5 Days)
Once hardware is installed, the real work begins. The installer configures the access control software, enrolls users, and sets access rules. They test every reader, verify door strike functions, and confirm emergency override mechanisms work.
You'll also receive staff training on the admin interface—how to add/remove users, generate reports, and troubleshoot common issues. This phase is critical; a poorly configured system frustrates users and creates security gaps.
Handover & Go-Live (1 Day)
The installer provides documentation, password credentials, and a final walkthrough. You sign off, and the system goes live. Many installers offer 30 days of free support post-launch to handle teething problems.
Frequently Asked Questions
Q: How much does an access control system typically cost? A: Basic single-door systems start around $2,000–$4,000; multi-door commercial setups range $10,000–$100,000+ depending on reader type, server infrastructure, and integration needs.
Q: Can I use my existing network cabling for access control? A: Often yes, especially for IP-based readers, but an installer must verify your network meets bandwidth and latency requirements to avoid connectivity dropouts.
Q: What happens if power fails? A: Quality systems include battery backup (4–8 hour runtime typical) and mag locks with fail-safe or fail-secure logic—your installer should test this during commissioning.
