Frequently Asked Questions - E-942FC-1K3SQ Seco-Larm

What is the typical use of the Seco-Larm E-942FC-1K3SQ?

It is a magnetic contact switch used for detecting open or closed status of doors, windows, or gates in security systems.

How do I wire the E-942FC-1K3SQ?

The switch has three wires: common (C), normally open (NO), and normally closed (NC). Connect COM to the control panel, NO for alarm on opening, NC for alarm on closing.

What is the maximum gap between the magnet and the switch?

The maximum recommended gap is 0.75 inches (19 mm) for reliable operation.

Can this contact be used outdoors?

The housing is ABS plastic, but it is not waterproof. It should be installed in a dry location or protected from moisture.

What voltage and current can the switch handle?

It is rated for 30 VDC or 24 VAC max, and 0.5 A max. It is suitable for low-voltage security systems.

Does the Seco-Larm E-942FC-1K3SQ require a power supply?

No, it is a passive device that does not require external power. The control panel provides the sensing voltage.

How do I mount the E-942FC-1K3SQ?

Mount the reed switch on the door frame and the magnet on the door, aligning them within the gap distance. Use the included screws or double-sided tape.

Is the E-942FC-1K3SQ compatible with all alarm panels?

It works with any panel that supports normally open or normally closed loops. Check the panel's wiring specifications.

What is the warranty on this product?

Seco-Larm typically offers a limited lifetime warranty. Contact their support for specific terms.

Can I replace only the magnet if lost?

Yes, the magnet is a separate component. You can purchase a replacement magnet from Seco-Larm or use a compatible one.

TROUBLESHOOTING

Problem:	Possible cause:	Solutions:
Gate does not lock	No power	Check to make sure the wires are secureCheck that the power supply is connected and operatingMake sure the unit is wired correctly
Gate locks, but can be easily forced open	Poor contact between electromagnet and armature plate	Make sure the electromagnet and armature plate are properly alignedMake sure the contact surfaces of the electromagnet and armature plate are clean and free from rust
	Incorrect voltage setting	Check the power leads with a meter, and make sure the correct voltage is present
Delay in gate releasing	A secondary diode was installed across the electromagnet	The electromagnet is fitted with a metal oxide varistor to prevent interference, so do not install a secondary diode

REGULAR MAINTENANCE

• Clean the contact surfaces of the electromagnet or armature plate with a soft cloth and non-abrasive, non-corrosive cleaner.
• Apply a light coat of a silicon lubricant to both contact surfaces and wipe away the excess to prevent rust.
• Check that the armature plate is securely attached to the bracket, yet can pivot slightly around the armature screw.
• Check that the electromagnet is securely attached to the bracket.

UL CERTIFICATION

MOUNTING THE ELECTROMAGNETIC LOCK

A. Determine type of gate:
1. Single-swing gate — Gate swings on one end, and comes to rest on a fixed gate post when closed. In this case, a typical installation has the electromagnet fixed to the gate post, and the armature connected to the free end of the gate.
2. Double-swing gate — Two gates swing in the same direction when activated. The electromagnet is fixed to the free end of one gate, and the armature is fixed to the free end of the other.
3. Sliding gate — The gate slides instead of swings away from a fixed gate post. A typical installation has the electromagnet fixed to the gate post, and armature connected to the free end of the gate.
B. Mount the electromagnet — In most cases, the position of the electromagnet will determine the location of the armature plate. Make sure there is space to run the cable.
1. Tack weld bracket into place. (Tack weld only.)
2. Dismount the electromagnetic lock from the bracket. Warning: Failure to remove electromagnetic lock will result in severe damage to lock. Weld 3 or 4 beads about 1" apart. Make sure not to weld the junction box. (See diagram for "No Weld" areas.)
3. Remount the electromagnetic lock.

C. Mount the armature —

1. Once the electromagnet is mounted, determine the armature bracket location and tack weld into place. (Tack weld only.)
2. Dismount the armature plate from the bracket. Warning: Failure to remove the armature plate from the bracket will damage the armature and rubber washer. Weld the armature bracket with 3 or 4 beads about 1" apart. Make sure not to weld near the set screw hole. (See mounting diagram for "No Weld" areas.)
3. Remount the armature.

a. Put one rubber washer between two steel washers, and place them over the armature screw between the armature and the bracket. This will allow the armature to pivot slightly around the armature screw in order to compensate for gate misalignment.
b. Make sure the guide pins are inserted into guide holes to prevent the armature from spinning.
c. Do not overly tighten the armature against the bracket. The armature must be able to pivot around the armature screw.

D. Run the wires — The goal is to keep as little of the wires exposed as possible.

1. Run the wires into an out-of-sight location as close as possible to the electromagnet.
2. Use standard armored cable to prevent the wires from being cut between the electromagnet and the out-of-sight location.

E. Connect the wires: Note: Unit is prewired for 12V operation. See Wiring Diagram below for more information.

1. For 12V operation — Connect the red and white wires to +12VDC, and the black and green wires to ground.
2. For 24V operation — Connect the red wire to +24VDC, the green wire to ground, and then tie the white and black wires together and insulate.

IMPORTANT: Damage caused by improper connection will void warranty.

F. Test the unit.
G. Insert the tamper caps into the mounting screw access holes of the electromagnet. This should be the last step, as once the tamper caps are in place, they are difficult to remove.
