Overview

Installation Applications

• When mounting the electromagnet, it may be necessary to use a “Z” and “L” bracket, an “L” bracket, a “U” bracket, and/or plate spacers, depending on the location and the type of door and frame.
• Use the diagram below to help decide whether or not an optional bracket will be necessary for installation.

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. Please see the diagram on page 3 to decide if a particular application requires any mounting accessories.
4. Do not run power wires and signal wires in the same conduit as this may cause interference.
5. Do not install a diode in parallel with the electromagnetic lock as this may cause a delay when releasing the door as well as cause residual magnetism.
6. The best location to install the electromagnetic lock is on the inside of the door that is being secured with the wiring concealed in the frame to prevent tampering with the unit.
7. The minimum permissible wire size to be used shall not be less than 22AWG.

Installation

1. Fold the mounting template along the dotted line to form a 90-degree angle.
2. Close the door. Find a mounting location on the door frame near the upper free-moving corner of the door, or as close as possible to the upper corner of the door frame opposite the hinges.
3. Use a hammer to lightly tap the two guide pins into the guide pin holes on the armature plate.
4. Place the template against the door and frame. Mark where the holes are to be drilled.
5. Drill holes in the frame and the door as shown on the template and in step #6 below. The smaller holes on the door should not go all the way through.
6. Depending on the type of door being protected, drill holes according to the diagrams below: Drill a 5/16″ hole (8mm) diameter hole through the armature-plate side of the door for the armature screw. Then drill a 5/8″ (16mm) diameter hole for the sexnut screw on the opposite side of the door. Drill a 1/4″ hole (6.8mm) diameter and 1″ (25mm) deep hole, tap for M8x1.25 thread. Drill a 5/16″ hole (8mm) diameter hole in the door for the armature screw and drill a 1/2″ (12.7mm) diameter and 1″ (25mm) deep hole from the opposite side for the sexnut screw
7. Put a rubber washer between the two metal washers and place them over the armature screw between the armature plate and the armature plate holder. This allows the plate to pivot around the screw to compensate for door misalignment.
8. Tighten the armature screw enough so that the armature plate can withstand a break-in attempt, but loose enough so that the armature plate can pivot slightly. Make sure the anti-spin guide pins are in the two guide pin holes.
9. Screw the two short self-tapping screws through the mounting plate’s slotted holes, but do not over-tighten them. Keeping them loose will allow for adjustment of the plate so that the long edge of the mounting plate and the armature plate are parallel. See the diagram below.
10. Once the mounting plate position is correct, use the four long self-tapping screws to permanently mount the mounting plate.
11. Drill the cable access hole. Run the wiring through the cable access hole in the mounting plate and through the hole in the door frame.
12. Remove the cover from the front of the electromagnet. Run the power leads through the large cable access hole.
13. Push the electromagnet against the mounting plate so the electromagnet ends are flush with the ends of the mounting plate. Use the Allen wrench to screw the hex-head mounting screws through the bottom of the electromagnet into the mounting bracket.
14. Cut the wires so they are long enough to connect with the terminal block. Set the voltage using the selection jumpers based on your input voltage. NOTES
    • Failure to correctly set the input voltage may cause damage to the lock.
    • connect switching devices like push-to-exit switches between the power source and the positive terminal on the lock. Connecting switching devices to the negative terminal may cause a delay in unlocking.
15. Connect the power and other wires according to the wiring diagram on page 7. Test the unit. Then replace the front cover and install the hex-head tamper caps (x2).
    NOTE: This should be the very last step after all steps are confirmed, since once the tamper caps are in place, they are very difficult to remove.

Wiring Diagram

*A fail-safe lock unlocks when power is lost so that, in case of an emergency such as a fire in the building, the fail-safe lock will automatically unlock allowing personnel to escape quickly.
NOTE: All field wiring must be within the protected area.

Troubleshooting

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.
• Make sure the rubber washer is installed and free from damage.

Delay in door releasing

• The electromagnet is fitted with a metal oxide varistor to prevent interference, so do not install a second diode.
• Ensure that the control device is connected between the power source and the positive terminal of the lock
