EM Lock
What is an EM Lock?
An electromagnetic lock (EM lock) consists of an electromagnet and an armature plate. When an electric current passes through the electromagnet, it creates a powerful magnetic field that tightly bonds the armature plate to the frame, keeping the door locked. Since they have no moving parts, they are virtually immune to mechanical wear and tear, unlike traditional deadbolts.
Why Choose EM Locks?
Fail-Safe Security: If the power fails, the lock releases immediately. Consequently, these locks are ideal for emergency fire exits.
Instant Operation: The system locks and unlocks the moment it receives a signal.
Durability: These locks resist physical wear, making them perfect for high-traffic offices in Kathmandu.

EM Locks vs. Other Electronic Locks: Which is Best for You?
When shopping for security in Nepal, you will likely encounter three main primary types of electronic locks. Each serves a unique purpose, and choosing the wrong one can lead to security gaps or security code violations. To help you decide, here is how EM lock compares to its common alternatives:
1. EM Lock vs. Electric Strike
While both provide electronic access, they secure doors using fundamentally different methods. Consequently, your choice depends on whether you prioritize fire safety or constant property protection.
Electric Strike: This device replaces your frame’s standard strike plate with an electromechanical "keeper." Specifically, it uses a motorized latch to hold your door’s existing bolt. Since it can be "Fail-Secure," the door remains locked even during a power outage, though you can still exit manually from the inside.
EM Lock: In contrast, an EM lock uses a powerful electromagnet to bond with a metal plate on the door. It is strictly "Fail-Safe," meaning it automatically unlocks if the power fails. Therefore, it is the superior choice for glass doors and emergency fire exits where immediate egress is mandatory.
2. EM Lock vs. Electric Drop Bolt
While both systems offer high-end security for modern offices, they differ significantly in their mechanical design. Consequently, your choice depends on the type of door you have and how much maintenance you are willing to perform.
Electric Drop Bolt: This lock uses a solenoid to shoot a heavy metal pin into a hole in the door or floor. Specifically, it is the best option for "double-swing" doors that open both inward and outward. Because it is mortised into the frame, it remains hidden, offering a sleek, "invisible" look for modern glass partitions.
EM Lock: In contrast, an EM lock uses a powerful magnet to bond with a surface-mounted plate. It has no moving parts and is strictly "Fail-Safe," meaning it releases instantly during a power cut. Therefore, it is the most reliable choice for high-traffic main entrances where durability and fire safety are the top priorities.
Specialized Solutions for Different Entry Points
1. Magnetic Lock for Wooden Door
Wooden doors are the standard for most homes and private cabins. However, a Magnetic Lock for Wooden doors requires a specific ZL bracket to mount correctly. The ZL bracket allows the armature plate to sit flush against the magnet, ensuring a secure grip even if the door frame is uneven.
2. Electromagnetic Lock for Gate
Securing an outdoor entry requires a specific Electromagnetic Lock for Gate. Unlike indoor locks, these must be waterproof (IP66 or IP67 rated) to withstand Nepal’s heavy monsoon rains. They are commonly used in residential colonies and apartment complexes in Lalitpur and Kathmandu. These gate locks often feature a higher holding force (up to 500 kg) to secure heavy metal gates against high winds and physical pressure.
3. Electromagnetic Lock with Sensor
For sensitive areas like server rooms, you should install an Electromagnetic Lock with a sensor In fact, these sensors monitor the “lock status” in real-time. If someone leaves the door, the sensor triggers an alarm, preventing unauthorized entry.
Installation Essential Components
Buying the lock is only the first step. To make it functional in your Nepali home or office, you will need the following components:
Access Controller: Use a fingerprint, card, or face-recognition reader to trigger the lock.
Power Supply with Battery: Since EM locks unlock when the power goes out, a battery backup is mandatory for constant security.
Push-to-Exit Button: Install this inside the room so people can exit easily.
Mounting Brackets:
U-Bracket: For frameless glass doors.
L/ZL Brackets: For wooden or metal doors.
Why Buy Locally in Nepal?
While international sites might offer lower base prices, buying your EM lock from a local vendor in Kathmandu or via platforms like Nepal Best Deals offers several advantages:
On-site Support: Access control systems require precise alignment; local technicians can handle the installation.
Warranty: Most local distributors offer a 1-year replacement warranty on brands like ZKTeco or Dahua.
Customization: Local experts can assess whether you need a 180 kg or 280 kg lock based on your specific door weight.
Conclusion
Whether you are looking for a simple Magnetic Lock for Wooden door or a heavy-duty Electromagnetic Lock for Gate, the investment is well worth the peace of mind. By focusing on the best EM locks in Nepal and ensuring you have a proper backup power system, you can create a seamless and secure environment for your assets.
