1. GENERAL ACCESS CONTROL QUESTIONS

  1. What is an access control system?

    An access control system is a security setup that controls who can enter or exit a building or room.

    It typically includes:

    • Locking device (e.g. electromagnetic lock)
    • Access control panel (card, PIN, fingerprint)
    • Access control panel (card, PIN, fingerprint)
    • Power supply
    • Power supply

    These components work together to ensure both security and safe access.

  2. What components are needed for a complete door access system?

    A standard system includes:

    • Electromagnetic lock (EM lock) → Keeps the door secured
    • Electromagnetic lock (EM lock) → Keeps the door secured
    • Exit button → Allows users to exit safely
    • Power supply → Provides stable power
    • Emergency door release → For fire safety compliance

    Elock offers all these components, designed to integrate seamlessly.

  3. How do EM lock, exit button, and power supply work together?
    • The power supply provides electricity to the system
    • The EM lock stays locked when powered
    • The access control system grants entry
    • The exit button cuts power to unlock the door

    This creates a safe and efficient access control system.

  4. What is the best access control setup for an office?

    For most offices, the recommended setup is:

    • 600lbs/1200lbs EM lock
    • Card or PIN access control
    • Exit button
    • Backup power supply

    This ensures:

    • Strong security
    • Easy user access
    • Safety during emergencies

2. TROUBLESHOOTING & COMMON PROBLEMS

  1. Why is my electromagnetic lock not holding?

    Common causes include:

    • Insufficient power supply
    • Misalignment of armature plate
    • Weak holding force
    • Wiring issues

    Elock locks are designed with stable current and strong magnetic force to minimize these issues.

  2. Why is my access control system not working?

    Check the following:

    • Power supply output
    • Wiring connections
    • Controller settings
    • Lock compatibility

    Most issues are caused by wiring or power instability.

  3. Why does my EM lock make noise?

    Possible reasons:

    • Loose installation
    • Vibration from door movement
    • Uneven contact surface

    👉 Ensure proper alignment and firm mounting.

  4. Why does my power supply fail?
    • Overload (too many devices connected)
    • Voltage fluctuation
    • Poor quality components

    Elock power supplies include overload and short-circuit protection to prevent such failures.

3. ELECTROMAGNETIC LOCK (EM LOCK)

  1. What is an electromagnetic lock?

    An EM lock uses a magnet and armature plate to secure a door.

    • Power ON → Locked
    • Power OFF → Unlocked
  2. What holding force do I need?
    • 300lbs → Cabinets / light doors
    • 600lbs → Standard doors
    • 1200lbs → Commercial use
    • 1500lbs → High-security applications
  3. How do I know if my EM lock is good quality?

    Key indicators:

    • Stable resistance (~50 ohms)
    • Proper current consumption
    • Strong holding force
