SECO-LARM ELECTROMAGNETIC LOCK Table of Contents: Introduction Features Parts List Specifications Overview Installation Applications 2 2 2 2 3 3 Installation Notes Installation Wiring Diagram Maximum Wiring Distance Troubleshooting Warranty 4 4-6 7 7 8 8 Introduction: The E-941DA series of electromagnetic locks is the ideal way to secure double doors against unauthorized entry. When power is applied to the electromagnetic locks, it creates an extremely strong magnetic field.
SECO-LARM ELECTROMAGNETIC LOCK Overview: Long selftapping screws Armature screw Short selftapping screws Guide pins Mounting plate Rubber washer Electromagnet Hex-head mounting screws Steel washers Tamper caps Door spacer Sexnut bolt Armature plate Installation Applications: NOTE: When mounting the electromagnets, 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 doors 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 locks are designed for indoor use ONLY. 3. The most suitable mounting location for the electromagnetic locks 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 two 5/16” (8mm) dia. holes through the armature-plate side of the doors for the armature screws. Then drill two 5/8” (16mm) dia. holes for sexnut screws on the opposite side of the doors. Drill two 1/4” (6.8mm) dia. and 1” (25mm) deep hole, tap for M8x1.
SECO-LARM ELECTROMAGNETIC LOCK 10. Once the position of the mounting plate is 11. Drill the cable access holes. Run the power leads through correct, use the eight long self-tapping screws to permanently mount the mounting plate. the cable access holes in the mounting plate and through the holes in the door frame. Long self-tapping screws 12. Remove the cover from the front of the 13. Push the electromagnet against the mounting plate so the 14. Cut the wires so they are long enough to 15.
SECO-LARM ELECTROMAGNETIC LOCK Wiring Diagram: CAUTION: Each lock has its own circuit board, for a total of two circuit boards. Please wire each circuit board and program the voltage-jumper selections according to the diagram below. LED Bond Status Sensor: The Bond Status Sensor checks to make sure the door is closed, and the electromagnet is locked. Relay 1A@24VDC LED Indicators: Green Door is closed and locked Red Door not closed and/or locked Door in use / No power Off N.C. COM N.O.
SECO-LARM ELECTROMAGNETIC LOCK Troubleshooting: Doors do not lock Bond status LEDs do not Illuminate Doors lock, but can easily be forced open Make sure the electromagnet and armature plates are properly aligned. Make sure the contact surfaces of the electromagnet and armature plates 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 locks. See below.
