HOW THEY WORK  
When power is applied to the magnetic lock, it turns on the unit's powerful built-  
in electromagnet. This electromagnet is attracted to the steel armature plate  
which is mounted on a door, holding the door fast against unauthorized entry.  
When power to the magnetic lock is turned off, the electromagnet releases the  
armature plate, allowing the door to open.

ELECTROMAGNETIC LOCK Installation Manual  
TROUBLESHOOTING  
Problem:  
Possible cause: Solutions:  
Door does not lock  
No power  
• Check to make sure the wires are  
securely tightened to the terminal block  
• Check that the power supply is connected  
and operating  
• Make sure the lock switch is wired  
correctly  
Door locks, but can be  
easily forced open  
Poor contact between  
electromagnet and  
armature plate  
• 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 rust  
Incorrect voltage  
setting  
• Check the power leads with a meter, and  
make sure 12VDC or 24VDC is present  
Delay in door releasing  
A secondary diode was • The electromagnet is fitted with a metal  
installed across the  
electromagnet  
oxide varistor to prevent interference, so  
do not install a secondary diode  
REGULAR MAINTENANCE  
• Clean the contact surfaces of the electromagnet or armature plate with a soft cloth and non-  
abrasive, non-corrosive cleaner.  
• Apply a light coat of a silicon lubricant to prevent rust. Wipe away the excess.  
• Check that the armature plate is securely attached to the door, yet can pivot slightly around the  
armature screw.  
• Check that the electromagnet is securely attached to the door frame.  
UL CERTIFICATION  
E-941SA-600 and E-941SA-1200 electromagnetic locks conform to UL/10B “Fire Tests of Door  
Assemblies” and UL/10C “Positive Pressure Fire Tests of Door Assemblies” for swinging door  
assemblies. They are also classified in accordance with the Uniform Building Code standard 7-2.
