CAUTION
Cautions indicate potentially hazardous conditions, which if not avoided or corrected, may cause minor or moderate injury. Cautions may also warn against unsafe practices

CAUTION
Remove any diode installed across the magnetic lock for spike suppression. The magnet is fitted with a metal oxide varistor to prevent back EMF

Use only Hardware provided with these products for mounting. Door thickness should be 13/4″ thick, otherwise different sex nut will be required. Door Header shall be minimum 23/4″ thick and flat surface is needed to securely mount screws for magnet, may need filler plates or angle bracket to  mount magnet correctly.

Introduction

The E-941Sx series of electromagnetic locks is the ideal way to secure a door against unauthorized entry. When power is applied to the electromagnetic lock, it creates an extremely strong magnetic field. The electromagnet is strongly attracted to the steel armature plate which is mounted on the secured door. Once the electromagnet is deactivated, the secured door will function normally without any residual magnetism.

Overview

Installation Applications

NOTE : When mounting the electromagnet, it may be necessary to use a “Z”-bracket, 1 or 2 “L”- brackets, 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, and L-brackets. 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.

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. Place the template against the door and frame. Mark where the holes are to be drilled
4. Drill two holes in the frame and three 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 plate.
6. Depending on the type of door being protected, drill holes according to the diagrams below:
7. Put a rubber washer between the two metal washers and place them over the armature screw between the armature plate and the door. 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 left or right so that the mounting plate and the armature plate form a 90-degree angle. See the diagram below.
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.
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 Hex 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.
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
    NOTE : This should be the very last step, as once the tamper caps are in place they are very difficult to remove

Wiring Diagram

POWER SUPPLY: The product must be powered from a UL-listed, regulated, power-limited, power supply. If power switch is not wired between DC source voltage (+) and magnet, it will take a longer time to de-energize the magnet simulating residual magnetism. The minimum permissible wire size to be used shall not be less than 22 AWG

NOTE: 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.

Troubleshooting

Maintenance
Wipe the surface of magnet lock with anti-rust oil regularly.

Door does not lock

• 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 rubber washer is installed and free from damage.

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