When power is applied to the electromagnetic lock, it creates an extremely strong magnetic field.
SECO-LARM ELECTROMAGNETIC LOCK Overview: Short selftapping screws Armature screw Mounting plate Rubber washer Long selftapping screws Guide pins Electromagnet Steel washers Armature plate Door spacer Hex-head mounting screws Sexnut bolt Tamper caps Installation Applications: NOTE: When mounting the electromagnet, it may be necessary to use a “Z”-bracket, 1 or 2 “L”-brackets, and/or plate spacers, depending on the location and the type of door and frame.
SECO-LARM ELECTROMAGNETIC LOCK Installation Notes: 1. Read this installation manual thoroughly. A clear understanding of the product and this manual will make installation much easier. 2. The electromagnetic lock is designed for indoor use ONLY. 3. The most suitable mounting location for the electromagnetic lock may require the use of additional SECO-LARM accessories such as Z-brackets, L-brackets, and/or spacer plates.
SECO-LARM ELECTROMAGNETIC LOCK 6. Depending on the type of door being protected, drill holes according to the diagrams below: 5/8” (16mm) Solid Core Door Reinforced Door Hollow Metal Door 5/16” (8mm) 1/4” (6.8mm) for M8x1.25 thread Drill a 5/16” (8mm) dia. hole through the armature-plate side of the door for the armature screw. Then drill a 5/8” (16mm) dia. hole for sexnut screw on the opposite side of the door. Drill a 1/4” (6.8mm) dia. and 1” (25mm) deep hole, tap for M8x1.25 thread. 7.
SECO-LARM ELECTROMAGNETIC LOCK 10. Once the position of the mounting plate is correct, use the four long self-tapping screws to permanently mount the mounting plate. 11. Drill the cable access hole. Run the power leads through the cable access hole in the mounting plate and through the hole in the door frame. Long self-tapping screws 13. Push the electromagnet against the mounting plate 12. Remove the cover from the front of the so the electromagnet ends are flush with the ends of the mounting plate.
SECO-LARM ELECTROMAGNETIC LOCK Wiring Diagram: Bond Status Sensor: The Bond Status Sensor checks to make sure the door is closed, and the electromagnet is locked. (600PQ and 1K2P models ONLY) LED Indicators: Green Door is closed and locked Red Door not closed and/or locked Door in use / No power Off 600PQ and 1K2P models ONLY *NOTE: Connect switching devices like push-to-exit switches between the power source and the positive terminal on the lock.
SECO-LARM ELECTROMAGNETIC LOCK Troubleshooting: Door does not lock Bond status LED does not Illuminate Door locks, but can easily be forced open 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. Check the power leads with a meter, and make sure 12VDC or 24VDC is present. Use a meter to check the resistance of coils inside the lock. See below.
