Installation Instructions for SDC 1000R and 1000V Electric Latch Retraction Kit

Quick Installation Guide

The SDC LR100DHK kit is designed to retrofit exit devices for electric latch retraction. Key requirements include verifying space for the assembly, especially on 42" or 48" devices modified to fit smaller openings. Ensure you have a drill with a .107" bit and a 6-32 tap before beginning. The unit operates on 24VDC.

Installation Preparation

Before starting the installation, verify the distance from the end of the touchpad to the end rail. If the device has been modified to fit a 36" or smaller opening, there may not be sufficient space for the standard E.L.R. assembly. Consult the factory if you are unsure about compatibility.

Mounting the Adapter

Steps:

1. Remove and discard the existing dogging from the exit device.
2. Place the adapter over the device to use as a template.
3. Drill a .107" diameter thru-hole.
4. Tap the hole to accept a 6-32 thread.
5. Attach the adapter using the supplied 6-32 x 3/8" Truss Head Machine Screw.
6. Cut the existing base to the dimension shown in the diagram (2.450").

Installing the E.L.R. Assembly

Steps:

1. Place the E.L.R. linkage inside the adapter.
2. Secure it in place using the supplied retaining link and 4-40 x 1/4" Pan Head Screw.
3. Power the unit to cause the E.L.R. to pull towards the exit device.
4. Depress the push pad to position the E.L.R. into the working position.
5. Pull back on the E.L.R. assembly to remove any slack.
6. Fasten the set screws on the assembly to secure the kit into the device.
7. Release the push pad and verify operation by de-energizing and re-energizing the kit to ensure proper latch retraction.

Electrical Data

The unit requires 24VDC power. The wiring polarity is as follows:

• Red: (+)
• Black: (-)
• Current Draw: 700/200mA

Retro-Fitting Vertical Rod Devices

To ensure proper alignment when installing into a vertical rod device:

1. Disconnect the vertical rods from the device.
2. Install the electric latch assembly as described above.
3. Energize the unit so the push pad is dogged down; this allows for proper alignment of the vertical rods.
4. Reconnect the vertical rods to the device and make necessary adjustments.
