Overview

SECO-LARM E-941DA-600Q Double Door Electromagnetic Locks -
1Installation Applications

  • 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.
  • 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 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.
  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 locks as this may cause a delay when releasing the door as well as cause residual magnetism.
  6. The best location to install the electromagnetic locks is on the inside of the doors that are 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 doors. Find a mounting location on the center of the door frame, directly above where both doors meet when closed.

  3. Place the template against the door and frame. Mark where the holes are to be drilled.

  4. Drill four holes in the frame and six holes in the door as shown on the template.

  5. Use a hammer to lightly tap the guide pins into the guide pin holes on the armature plates.

  6. epending on the type of door being protected, drill holes according to the diagrams below:

    Drill two /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 M8x1.25 thread on each door.| Drill two 5 /16″ (8mm) dia. holes on the doors for the armature screws, and drill two 1 /2″ (12.7mm) dia. and 1″ (25mm) deep hole for the sexnut screws.

  7. Put a rubber washer between the two metal washers and place them over the armature screw between the armature plates and the doors. This allows the plates to pivot around the screw to compensate for door misalignment.

  8. Tighten the armature screws enough so that the armature plates can withstand a break-in attempt, but loose enough so that the armature plates can pivot slightly. Make sure the antispin guide pins are in the two guide pin holes.SECO-LARM E-941DA-600Q Double Door Electromagnetic Locks - 10 TIP: Use a thread-locking compound on the armature screws to ensure a long lasting installation.

  9. Screw the four short self-tapping screws through the mounting plate’s slotted holes, but do not overtighten them. Keeping them loose will allow for adjustment of the plate  left or right so that the mounting plate and the armature plates form a 90-degree angle. See the diagram below.

  10. Once the position of the mounting plate is correct, use the eight long self-tapping screws to permanently mount the mounting plate.SECO-LARM E-941DA-600Q Double Door Electromagnetic Locks - 12

  11. Drill the cable access holes. Run the power leads through the cable access holes in the mounting plate and through the holes in the door frame.SECO-LARM E-941DA-600Q Double Door Electromagnetic Locks - 13

  12. Remove the cover from the front of the electromagnets. Run the power leads through the large cable access holes.SECO-LARM E-941DA-600Q Double Door Electromagnetic Locks - 14

  13. Push the electromagnet against the mounting plate so the ends are flush with each other. Use the Allen wrench to screw the hex-head mounting screws through the bottom of the electromagnets into the mounting plate.

  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.
    CAUTION: The two electromagnets each have their own voltage selection jumpers.SECO-LARM E-941DA-600Q Double Door Electromagnetic Locks -
16 NOTE: Failure to correctly set the input voltage may cause damage to the lock.

  15. Connect the power wires according to the wiring diagram on page 7. Test the unit. Then replace the front cover and install the hex-head tamper caps (x4).

NOTES

  • Connect switching devices like push-to-exit switches between the power source and the positive terminal of the lock. Connecting them to the negative terminal may cause a delay in unlocking.

 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
