Fail-safe or fail-secure mode
Magnetic strike door locks only operate in fail-safe mode because they depend on a permanent power supply. If there is a power outage, the magnetic force is released and the door can be opened from either side. A back-up power supply is therefore essential to protect secure areas.
How does a fail secure magnetic lock work?
Most fail secure locks use a technology known as electric latch retraction (EL), which basically means that power is required to retract the latch and unlock the door. The latch stays in a retracted position as long as power is applied, but as soon as power is cut off, the latch projects out again, locking the door.
Are electromagnetic locks secure?
Electromagnetic locks are commonly used in hotels, offices and residential blocks as they are secure, reliable and quick to install, as there are few components.
Why is my magnetic door not locking?
Possible Problems. Physical weariness. The latch may not be properly placed in the electric striker, the magnetic lock may not be properly aligned due to mechanical force or weariness, and the power supply to the striker can be insufficient.

How do you beat electromagnetic door locks?
Take a flat piece of steel about 2 feet long and 3/8″ wide and bend it with a curve on the end in a half-circle 4″ in diameter. Now, by simply slipping the curved part through the gap in the doors, I can touch the bar on the inside with this conductive metal and fool the lock into thinking I’m inside and unlocking.
How strong is a mag lock?
The average magnetic lock can withstand up to 1200 pounds of force. Ease of installation. Maglocks are relatively easy to install.
What is fail-safe and fail secure?
Understanding the basics: Fail safe products are unlocked when power is removed. Power is applied to lock the door. Fail secure products are locked when power is removed. Power is applied to unlock the door.
Can you open a lock with a magnet?
The magnet doesn’t make the lock move: Every lock will work differently, but it’s typically friction that causes this problem. If a piece of your lock is supposed to move, be sure it can move easily. If it’s attached too tightly, your magnet may not be able to move it.
How do you release a magnetic door?
The way to do this is relatively straightforward. You’ll have to connect the power, at which point you actually test the lock’s unlocking capabilities with whatever access system you have at hand. When the lock is powered, it should hold the door closed tightly, and when the power is cut, the lock should open.
How do you bypass a deadbolt without a key?
One of the best-known ways to unlock a deadbolt without a key is by using two bobby pins. Start by inserting the closed “looped” side of one bobby pin into the bottom portion of the lock. Use the second bobby pin, broken in half, toward the top of the lock and move it back and forth.
Can you use a paperclip to pick a lock?
Picking a lock with paper clips works pretty much the same way as picking a lock with a traditional tension wrench and rake. You just need to turn two paper clips into those two very same tools, and then pick the lock with them like you’d normally do.
How do you wire a fail-secure lock?
Fail-secure means the doors will lock when power is removed. Wire the positive leg directly to the lock. Connect the negative leg from the power supply, through the normally open relay on your controller, to the lock.
What happens to a fail-safe electrified mortise lock when the power is turned off or fails?
In fail-safe mode, power must be applied to lock the lock, whereas in the fail-secure mode power must be applied to unlock the lock. Thus when power to the lock is disengaged or “fails”, the lock will go to its fail-safe (unlocked) or fail-secure (locked) mode. Most electrified mortise locks are ordered as fail-safe.
How do you test a Maglock?
The maglock must be tested by using the armature that comes with the lock. When the maglock and armature are correctly mounted and the magnet is energized, the armature will seat completely flush to the face of the maglock.
How much power does magnetic door lock use?
The power for an electromagnet lock is DC (direct current), around 5–6 W. The current is around 0.5 A when the voltage supply is 12 VDC and 0.25 A when using 24 VDC (varies between manufacturers and if there are one or two coils in the block).
How can I open lock without key?
The non-locking side of the door should have a small hole on the face of the knob. Hidden inside the hole is a small button that must be pushed to unlock the door. You simply need a straight, stiff tool to unlock it. Try using a straightened paperclip or a tiny eyeglass-repair screwdriver.

Does an electric strike need a power supply?
Electric strikes require a power supply to function. Electric strikes have some type of keeper, or gate, for the latching mechanism on the lock. When a credential is presented and the strike is disengaged, the gate on the strike will allow the latch to be pulled through the gate.
What will happen to the access control when electricity fails?

What can block a magnet?
The simple answer is that it is not possible to totally ‘block’ a magnetic field. The essence of a magnet, as determined by nature, is that magnetic field lines must terminate on the opposite pole and, therefore, there is no way to stop them.
Do magnets wear out over time?
The magnetic field in a permanent magnet does tend to decay over time, but not with a predictable half-life as with radioactivity. “Permanent” or ferromagnetic materials have tiny regions, or domains, of 0.1 to 1 millimetre in length.
Do magnetic locks work without electricity?
If power goes out, the magnetic lock will not work. Without an electronic strike, entry to the building is as easy as simply opening the door. Add an electronic strike to the secure door, and even when the power goes out, the door is still secure.
Can a magnet unlock a deadbolt?
A magnet cannot entirely unlock a deadbolt.
