🔍 1. First Step: Door Condition Inspection (Mandatory Before Any Install)

Before installing any intercom or mechanical locking system, the door must be fully functional on its own. A system installed on a misaligned door will fail over time.

We always check:

  • Door closing properly without obstruction
  • No air pressure resistance affecting closure
  • Hinges not sagging or over-tight
  • Floor clearance issues (rubbing, lifting, scraping)
  • Debris, rocks, salt, or buildup blocking door swing
  • Door closer working correctly (no oil leaks, correct tension)
  • Frame alignment and latch engagement

👉 If the door does not close smoothly by itself, no system should be installed yet. Alignment always comes first.

⚙️ 2. Preparing for Intercom + Mechanical Lock Installation

Once the door is properly aligned and closing correctly, we proceed with installation planning.

Typical commercial setup includes:

  • Intercom system (access control or visitor call system)
  • Mechanical lock or latch system
  • Electric strike or reinforced strike plate (when applicable)
  • Exit device or lever handle system
  • Optional keypad or timed access system

🚪 3. Exit Hardware & Safety Rules (Very Important)

All commercial exit hardware must respect safety and fire exit regulations:

  • Push paddle or panic bar must NEVER be installed too high
  • Hardware must be accessible for all users (adults, children, emergency exit)
  • Exit must always allow:
    • Push
    • Pull
    • Down lever operation (depending on device type)

👉 The goal is always: fast, easy exit without confusion during emergency situations

🔓 4. Night Security Options (High-Risk Locations Only)

For locations experiencing theft or repeated break-ins, additional reinforcement can be discussed:

  • Mechanical night lock bolt (internal locking option)
  • Thumbturn required for fast emergency exit
  • Reinforced strike plate (6 7/8” cover plate for existing damage or wear areas)

⚠️ Important:
Any additional locking system must always respect local fire and building codes.

  • Single-tenant private areas may allow extra night security solutions
  • Multi-tenant commercial buildings must always remain code-compliant and free exit accessible at all times

We will always recommend safe and legal configurations depending on building type and occupancy.

🧱 5. Strike & Lock Alignment (Critical Step)

Before installing any strike or electric strike:

  • Door must be perfectly aligned
  • Latch must engage smoothly without force
  • No lifting or pushing required to lock
  • Frame must not be under stress or deformation

Installing a strike on a misaligned door will cause:

  • Premature lock failure
  • Door jamming
  • Customer access issues
  • Security weakness under pressure

🛠️ 6. Final Installation Outcome

A properly installed system provides:

  • Controlled access through intercom
  • Secure mechanical locking at all times
  • Smooth door operation with no resistance
  • Safe emergency exit compliance
  • Reduced break-in risk at latch/strike level

📌 Summary

A commercial intercom + lock system is only as strong as the door it is installed on.
80% of failures come from door alignment issues, not the lock itself.

That’s why we always fix the door first — then install the system.
