Fail-safe = unlock when no power (for safety) Fail-secure = stay locked when no power (for security) A fail-safe lock will unlock when power is lost. This is commonly used for safety reasons, especially on emergency exits, so people can leave the building easily during situations like a fire or power outage. EM locks are typically fail-safe. A fail-secure lock, on the other hand, will remain locked when power is lost. This is used where security is more important, such as restricted areas, because the door stays locked even during a power failure. Electric strikes are often fail-secure.

👉 It depends on your door type and installation direction. Simple Guide: 1. Check Door Type Wooden / Metal door (inward opening) 👉 Usually no bracket needed (direct install) Glass door (frameless) 👉 Use U bracket + glass bracket Glass door (with frame) 👉 Use L bracket or U bracket 2. Check Opening Direction: Inward opening door 👉 Standard mounting Outward opening door 👉 Use ZL bracket 3. Check Door Frame Space: Narrow frame / no space 👉 Use L bracket Common Brackets: L Bracket → when frame is narrow ZL Bracket → for outward opening doors U Bracket → for glass doors (hold armature)

A key switch is important because it provides a secure, manual way to control a system using a physical key — especially when other access methods are unavailable or unsuitable. 🔐 Key Reasons Why It’s Important 1️⃣ Backup Access (Very Critical) 👉 If your system fails: Card not working Fingerprint error Controller issue ✅ Key switch allows manual override to unlock the door 2️⃣ Emergency Control 👉 In urgent situations: System malfunction Need immediate access ✅ Authorized person can quickly unlock using key 3️⃣ Higher Security Control 👉 Unlike exit buttons: Anyone can press a button BUT key switch requires a physical key ✅ Only authorized personnel can: Unlock door Enable/disable system 4️⃣ Prevent Unauthorized Operation Used in: Server rooms Control panels Restricted areas 👉 Ensures: Only key holders can operate 5️⃣ Industrial & Machinery Safety 👉 Common in machines: Start/stop machines Prevent accidental activation ✅ Adds a layer of: Safety Control Accountability ⚠️ What Happens Without It? ❌ No backup if system fails ❌ Hard to override during emergency ❌ Lower security control ❌ Higher risk in restricted areas 🧠 Simple Summary: 👉 Key switch = secure manual backup + control

Key Difference (Most Important): EM Lock → uses magnetic force to hold the door Electric Strike → uses a mechanical latch to lock/unlock Choose EM Lock if: Glass door or frameless door High traffic area Need fail-safe (fire safety) Want easier installation 👉 EM locks are strong and ideal for glass or high-traffic doors Choose Electric Strike if: Wooden or metal door Want to keep existing lock Need fail-secure (stay locked during power cut) Budget is lower 👉 Electric strikes are more cost-effective and work with existing locks EM lock is better for glass doors and safety (fail-safe), while electric strike is better for traditional doors and higher security during power loss (fail-secure).

Yes, ELOCK provides brackets like the EL-BK-G100, which are suitable for glass doors with thicknesses ranging from 9mm to 12mm. These brackets are designed to work with specific lock models, such as the ELOCK-B100 bolt action lock.

Choosing the right door contact mainly depends on door type, environment, and installation method. 1. Check Door Type Wooden / metal door → standard door contact Glass door → use glass door contact (with adhesive or special mount) Roller shutter → use heavy-duty shutter sensor 2. Indoor or Outdoor Indoor → standard type Outdoor / exposed area → choose weatherproof (IP-rated) 👉 Important if exposed to rain or dust 3. Contact Type (NO / NC) NC (Normally Closed) → most common for security systems NO (Normally Open) → used for specific setups 👉 If unsure, choose NC 4. Gap Distance (Important) 👉 This is the distance between magnet & sensor Small gap → standard doors Larger gap → uneven or heavy doors 5. Installation Type Surface mount → easy to install Flush mount → cleaner look but requires drilling Choose a door contact based on door type, environment (indoor/outdoor), contact type (usually NC), and installation method, making sure the sensor and magnet align properly.

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) • Exit button • Power supply • Emergency release These components work together to ensure both security and safe access.

Common causes include: • Insufficient power supply • Misalignment of armature plate • Incorrect installation • Weak holding force • Wiring issues Elock locks are designed with stable current and strong magnetic force to minimize these issues.

An electromagnetic lock (EM lock) is a security device that uses an electric current to create a magnetic force that holds a door closed. It consists of a magnet mounted on the door frame and a metal plate attached to the door. When power is supplied, the magnet keeps the door locked; when power is cut, the door unlocks. EM locks are commonly used in access control systems for offices, glass doors, and commercial buildings due to their reliability and ease of use.

An EM lock is normally powered ON to stay locked, so wiring is straightforward. Basic Connection 👉 Connect power supply directly to EM lock: Power Supply (+) → EM Lock (+) Power Supply (–) → EM Lock (–) 👉 When power is on → lock is engaged 👉 When power is cut → lock releases 🔧With Exit Button / Access Control To control unlocking, you add a switch in between: Connect exit button (NC contact) in series with the power line When pressed → it cuts power → EM lock unlocks 🔧 Typical Setup Includes: Power supply EM lock Exit button Access control device Emergency break glass Important Tips: Use correct voltage (12V or 24V) Ensure stable power supply Use backup battery for safety Connect the EM lock directly to the power supply (+ to +, – to –), and use an exit button or access control to cut the power when unlocking is needed.

A key switch allows authorized manual control of access systems. It is commonly used for: • Emergency override • Restricted access areas

Unstable voltage can cause: • System failure • Reduced lifespan • Malfunction A power supply converts electricity (AC from mains) into the correct DC voltage (e.g., 12V) to run devices like EM locks, access control systems, and sensors. 👉 Simple: it powers your system so everything can work properly.

Safety Reason (Very Important)! EM locks are designed this way mainly for life safety: In emergencies (fire, power failure) Doors must unlock automatically So people can exit quickly and safely This is required in many building safety standards. EM locks rely on electricity to lock, so when power is lost they automatically unlock — making them fail-safe for safety reasons.

A door contact sensor should be installed at the top of the door, where the door meets the frame. 👉 One part (sensor) is fixed on the door frame 👉 The other part (magnet) is fixed on the door leaf Important Tips: Place it close together when door is closed (usually within a few mm) Keep both parts aligned properly Avoid placing too low (can be damaged or misaligned) For EM Lock Setup: 👉 Usually installed near the EM lock area (top of the door) for easier wiring and accurate detection

1. Mount the EM Lock Fix the EM lock body on the door frame (top) Make sure it is secure and level 2. Install the Armature Plate Fix the armature plate on the door leaf It should align perfectly with the EM lock Leave a slight flexibility (using rubber washer) so it can sit flat when locked. 5. Test the System Power on → door should lock firmly Press exit button → door should unlock immediately Tips Use correct bracket (ZL, L, U) depending on door type Ensure stable power supply Avoid loose installation Install the EM lock on the door frame, fix the armature plate on the door, align both properly, connect to power and access control, and test to ensure it locks and unlocks correctly. 3. Check Alignment Close the door and ensure: EM lock and plate touch fully No gap or misalignment This is very important for strong holding force. 4. Wiring Connect the EM lock to: Power supply (12V/24V) Access control system / exit button / emergency release

A door contact is a sensor used to detect whether a door is open or closed. It consists of two parts:- A magnet A sensor (reed switch) 👉 When the door is closed, both parts are aligned and the system reads it as closed 👉 When the door opens, they separate and send a signal that the door is open Where it’s used? Access control systems Alarm systems Security monitoring A door contact is a sensor that monitors the open and closed status of a door for security purposes.

Transformers typically use enameled copper wire (also called magnet wire). What is Enameled Copper Wire? Copper wire coated with a thin insulation layer (enamel) Allows tight winding without short circuit Designed for high temperature and electrical use For Elock: Elock uses high-purity enameled copper wire for transformer windings. 👉 This ensures: Efficient power transmission Good insulation and safety Better heat resistance Long-lasting performance

An emergency door release (also called a break glass unit) is a safety device used to immediately unlock a door during emergencies. 👉 It is commonly installed together with: EM locks Access control systems 👉 Emergency door release ensures: Immediate exit during: Fire Power/system failure Panic situations

• 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.

A roller shutter sensor is a device used to detect whether a roller shutter door is open or closed. 👉 It works like a door contact but is designed for heavy-duty shutters (e.g., shops, warehouses). How it works (simple): One part is fixed on the shutter One part is fixed on the frame When the shutter closes → sensor detects it When opened → signal change
