How to Use Electromagnetic Locks

Here are some suggestions and recommendations for the installation and functionality testing to Use Electromagnetic Locks:

electromagnetic-lock-feature-illustration

Use Electromagnetic Locks – The electromagnetic lock requires a face to face fitting as shown in the illustration. Otherwise, the holding force will decrease (direction of hydraulic press pull must be collinear).

electromagnetic-lock-and-armature-plate

Install the electromagnetic lock and armature plate in the special test clamp which is designed for a collinear pull-off test. (The lock and clamp assembly are shown in the illustration). The armature plate direction of hydraulic press pull must be “collinear”, and armature plate centers on core.

electromagnetic-locks-fail-safe

All electromagnetic locks are “fail safe”. Therefore they require a UPS (Uninterruptible Power Supply) to remain locked during the power failure.

emlock-lz-or-z-brackets

The electromagnetic locks are suitable for out-swing door and inswing door applications. For inswing door applications, the locks should be fitted with “LZ “or “Z” brackets.

rubber-washer-between-armature-and-door-leaf

Do not tighten the armature on the door leaf. Insert a rubber washer between the armature and the door leaf to allow for the face-to-face contact between the armature and the electromagnet. Thus the electromagnetic lock will work effectively.

electromagnet-and-armature-plate

Make sure the contact surfaces of the electromagnet and armature plate are clean and free from dust. It is important to make sure that the armature plate and the electromagnet properly align to ensure effective operation.

12-24v-dc

Voltage Selection Jumper: Check jumper settings before connecting lock to a 24V DC input power. Damage to the lock may result from incorrect jumper setting.

electromagnetic-lock-reed-switch

The animation shows the location of the reed switch. The switch will send out signal when the electromagnet and armature plate interact correctly.

Trouble Shootings：

Problems	Possible Causes	Solutions
Door is not locked	No power	Make sure the wires are securely tightened to the correct terminal block. Check that the power supply unit is connected and operating properly. Make sure the lock switch is wired correctly.
The door is locked, but can be easily forced open	Poor contact between the electromagnet and armature plate	Do not tighten the armature to the door leaf. Make sure the electromagnet and armature plate are properly aligned. Make sure the contact surfaces of the electromagnet and armature plate are clean and free from dust.
The door is locked, but can be easily forced open	Low voltage or incorrect voltage settings	Ensure the electromagnetic lock is set for the correct voltage. Check if the input voltage is correct. If it’s too low, replace with a correct gauge wire to prevent excessive voltage drop.
Sensor output is not functioning	A second diode was installed across the electromagnetic lock	Remove the second diode installed across the maglock for spike suppression. (The electromagnet has been fitted with a metal oxide varistor to prevent back EMF.)
Sensor output is not functioning	Misalignment between the reed switch and the armature plate	Check the installation of armature plate with the template.
