SDC 1510 Magnetic Lock Instruction Manual

SDC 1510 Magnetic Lock

Product Information

The 1500 Series Emlock is a security door control system designed to be mounted on the underside of the header, on the stop side of the door. It can also be mounted on the hinge side of the door using the optional TJ mounting kit. The system consists of an electromagnet (mounted to the header) and an armature (mounted to the door). The armature is provided with a hardware kit to compensate for misalignment and wear of the door, allowing it to pivot on its center point.

Installation Instructions

1. Inspect the frame header to determine if an angle bracket or filler plate is required. Refer to Figure 1A, 1B, 1C forguidance.

2. If necessary, fold the template along the dotted line and position it against the door and header on the lock jamb side of the frame.

3. Mark and drill holes as indicated by the template. For armature plate hole preparation, refer to Figure 2A, 2B, 2C.

4. Mount the armature to the door using the provided hardware.
   Refer to Figure 2A, 2B, 2C for guidance on selecting the appropriate hardware.

5. Install the mounting plate to the header with the interlock detail facing away from the door side of the stop, using the provided #10 Flt Hd. Screws.

6. Hold the magnet housing at each end and engage the entire length of the interlock detail by pushing towards the door. If necessary, tap with a soft hammer to ensure proper alignment and engagement.

7. Secure the lock body with the mounting screws provided inside the housing. Tighten the screws and check alignment.

8. Test the operation of the system. Once everything is operating properly, tighten all screws. Install anti-tamper plugs over socket head screws using a soft hammer to avoid damage to the housing.

Surface Plating Maintenance

If the surface plating of the lock is damaged, follow these steps:

1. Do not touch the lock face with your hands.
2. Using a soft, clean, dry cloth or abrasive cloth (e.g.,Scotch-Brite), clean the lock face. Do not use sandpaper.

Armature Maintenance

The electromagnet and armature should be handled carefully to avoid damage to their surfaces. Any damage such as paint, burrs, dirt, and rust may hinder bonding and reduce holding power. To maintain the armature:

1. Apply a rust inhibitor (e.g., M1 by Starret or LPS3 by LPS Laboratories) to prevent rust formation. These inhibitors are available at most hardware stores.
2. Apply a coat of inhibitor to the armature face as well.

FAQ

Q: How do I determine if I need an angle bracket or filler plate for the frame header?
A: Inspect the frame header and refer to Figure 1A, 1B, 1C in the installation instructions to determine the requirement for an angle bracket or filler plate.

Q: What should I do if the surface plating of the lock is damaged?
A: Do not touch the lock face with your hands. Use a soft, clean, dry cloth or abrasive cloth (e.g., Scotch-Brite) to clean the lock face. Avoid using sandpaper.

Q: How should I handle the electromagnet and armature to avoid damage?
A: Handle the electromagnet and armature carefully to prevent any damage to their surfaces. Any damage such as paint, burrs, dirt, and rust may reduce the holding power. Apply a rust inhibitor (e.g., M1 or LPS3) to prevent rust formation and apply it to the armature face as well.

INSTALLATION INSTRUCTIONS

1510, 1570, 1580 SERIES EMLOCK®

The 1500 Series Emlock is mounted to the underside of the header, on the stop side of the door. A TJ mounting kit (optional) can be used when mounting on the hinge side of the door. (Fig. 1D)
The armature is mounted to the door. A hardware kit is provided to compensate for misalignment and wear of the door, by allowing the armature to pivot on it’s center point.

1. Inspect the frame header to determine if an angle bracket or filler plate is required. See Figure 1A. 1B. 1C.

2. Fold template as indicated by dotted line. For single doors, locate template against the door and header on the lock jamb side of the frame.

3. Mark and drill holes as indicated bt template. For armature plate hole preparation, see Figure 2A, 2B, 2C.

4. Mount armature to door. To determine proper hardware (provided), see Figure 2A, 2B, 2C.

5. Install mounting plate to header with the interlock detail away from the door side of the stop, with #10 Flt Hd. Screws provided.
   FIG. 2A HOLLOW METAL DOOR
   From Sexnut side of door, drill exactly 1/2″ hole thru one metal thickness only. From Armature side of door, drill 5/8″ hole to insert reinforcement tube. Press in sexnut and reinforcement tube all the way and mount armature to door using hardware provided per Figure 2B.

6. Holding the magnet housing at each end, engage the entire length of the interlock detail, by pushing towards the door.
   (If necessary, tap with a soft hammer to ensure proper alignment and engagement).
   Caution: The lock body must be held in place until secured with mounting screws. Screws provided inside the housing at each end. Tighten the screws and check alignment.

7. Test operation. When all is operating properly, tighten all screws. Install anti-tamper plugs over socket head screw using a soft hammer to avoid damage to the housing.
   Electromagnet and armature should be handled carefully.
   Any damage to the surface such as paint, burrs, dirt and rust may hinder bonding of surface and reduce holding power.
   SHOULD THE SURFACE PLATING BE DAMAGED:
   Do not touch the lock face with your hands.
   Using a soft, clean, dry cloth or abrasive cloth (i.e., Scotch-Brite), clean lock face. Do not use sand paper.
   A rust inhibitor such as M1, manufactured by Starret, or LPS3, manufactured by LPS Laboratories (available at most hardware stores) can then be applied.

Apply a coat of inhibitor to armature face also.

Drill 3/8” hole thru door. From sexnut side of door, drill exactly 1/2” hole,1-3/8” deep. Mount armature to door with hardware provided per Figure 2A.

FIG. 2C REINFORCED DOOR
Drill and tap for 5/16-18 machine screw. Mount armature to door with hardware provided per Figure 2C.

OPTIONAL: 1511-DF DRILL FIXTURE
Drill many doors and frames in a fraction of the time.

ELECTRICAL SPECIFICATIONS

Voltage kickback protection standard

(PER COIL)
HOLDING FORCE (LBS)| 1650| 1200| 650**

NOTE: For a proper coil resistance reading, turn off the DC voltage. Use an ohmmeter and measure the resistance between the pins of the plug connector positions E1-E2 and E3-E4

ELECTRICAL INSTALLATION

1. Use jacketed cable for all wire runs. Refer to the SDC wire gauge chart for proper lock power wire size (18 AWG gauge minimum).
2. Use only shielded cable for all signal wires. 22 AWG gauge (minimum) may be used for signal wires up to 1,000 feet.
3. All wires must be colored coded.
4. Use properly fused power source only. See Electrical Specifications.
5. Make all Emlock terminal connections according to Figure 3A or 3B.

IMPORTANT NOTES

INDOOR USE ONLY
Do not run power wires and signal wires in the same cable orconduit.
Do not install a diode in parallel with any magnetic lock. A diode will cause a delay when releasing the door and residual magnetism to occur.
Although SDC recommends the use of a DC power supply, a transformer with an adjacent mounted full wave bridge rectifier may be used. A significant voltage drop will occur when using a full wave bridge rectifier.
Any low voltage condition will cause erratic operation of the optional bond sensor.
When using a full wave bridge rectifier, all access controls and/or release contacts must be located between the Emlock and rectifier to ensure quick release.

AWG WIRE CHART

To determine the correct wire gauge to use on “one circuit” the following information is required:

1.  The quantity, voltage, and current draw of all lock(s) to be used.
2. The distance in feet from the power supply to the furthest lock.
   Add together the current draw (amps) of all locks on the same circuit. Cross reference the total amps with the distance between the power source and the furthest lock to determine the wire gauge required. All wiring must be installed in accordance with all state and local codes.

TROUBLESHOOTING

FILLER PLATES: For extension of the stop to provide a proper mounting surface on the underside of the header.
See Figure 1B.

ANGLE BRACKETS: Used as extension on shallow door frames to provide adequate mounting surface.
See Figure 1C.

• Multiple predrilled and tapped mounting holes to accommodate the use of several different locks on either 4″ or 4.5″ aluminum frames.
• Field adjustable for 1/2”, 5/8” and 3/4” all glass Herculite doors.
