Inserting a Device in Circuit

Command

Prerequisites

• A FireCAD project must be open
• An active circuit must be selected in the Circuits palette
• The active drawing must be part of the project

Overview

The ATINSERT_IN_CIRCUIT command adds a device to the active circuit at a specific position — before an existing device. Unlike ATCONNECT which adds devices at the end of the sequence, this command lets you control exactly where in the circuit order the new device appears.

Steps

1. Select the target circuit in the Circuits palette
2. Type ATINSERT_IN_CIRCUIT in the AutoCAD command line
3. Connected devices on the circuit are highlighted
4. You are prompted: "Select a device on circuit '[Circuit Name]' to insert before:"
5. Select the device that the new device should be placed before
6. You are prompted to select the device(s) to insert
7. Select one or more compatible devices
8. Press Enter to confirm
9. The device is inserted and sequence numbers for downstream devices are adjusted

How It Works

• The new device is inserted before the selected reference device
• All devices after the insertion point have their sequence numbers (MasterSequence) incremented
• Wire labels and addresses update to reflect the new order

Tips

• Use this when device addressing depends on circuit order (e.g., SLC addressing)
• For adding devices to the end of a circuit, ATCONNECT is simpler
• After insertion, you may want to run ATAUTO_DRAW_ACTIVE_WIREPATH to update the wirepath routing
