Prerequisites
- A FireCAD project must be open
Overview
The Project Circuits Editor is a comprehensive window for managing all circuit properties in your project. It provides a two-grid layout: the top grid displays circuit settings and the bottom grid shows circuit type limits for the selected circuit. This is the primary tool for configuring circuit electrical parameters, reporting flags, and display options.
Layout
The editor contains two main areas:
- Top grid — Circuit properties (one row per circuit)
- Bottom grid — Circuit limits for the selected circuit (one row per limit type)
Circuit Properties Grid (Top)
The circuit grid includes a search panel for finding specific circuits. Each row represents one circuit with the following columns:
Read-Only Columns
| Column | Description |
|---|---|
| Panel | Panel name (computed from cache) |
| Card | Card/node name (computed from cache) |
| Origin Part Number | Part number of the circuit's origin device |
| Device Properties | Description of entity properties |
| Circuit Types | Associated circuit types |
Editable Columns
| Column | Type | Description |
|---|---|---|
| Circuit Name | Text | Circuit identifier |
| Locked | Checkbox | Lock circuit to prevent modifications |
| Hidden | Checkbox | Hide circuit from normal views |
| Default Color | Color picker | Circuit display color in AutoCAD |
| Wirepath Label | Text | Custom wirepath label format |
| Show EOL | Checkbox | Display end-of-line indicators |
| EOL Value String | Text | Custom EOL display value |
| Voltage Drop Report | Checkbox | Include in voltage drop (PTP) reports |
| Address Schedule | Checkbox | Include in device schedule reports |
| Speaker Schedule | Checkbox | Include in speaker/decibel reports |
| T-Tap Wirefill | Checkbox | Enable T-tap wirefill calculation |
| Standby Current Max (A) | Decimal | Maximum standby current limit |
| Alarm Current Max (A) | Decimal | Maximum alarm current limit |
| Use Current Limits On Battery Calc | Checkbox | Apply limits to battery calculations |
| Watt Limit | Decimal | Maximum circuit wattage |
| Starting Calculation Voltage | Decimal | Initial voltage for calculations (default 20.4V) |
| Min Voltage | Decimal | Minimum acceptable voltage |
| Max Circuit Length (ft) | Decimal | Maximum wire run length |
| Current Max Threshold % | Percentage | Warning threshold for current (default 80%) |
| Watt Max Threshold % | Percentage | Warning threshold for wattage |
| Report Order | Integer | Display order in reports |
Circuit Limits Grid (Bottom)
When you select a circuit in the top grid, the bottom grid shows its limit types:
| Column | Type | Description |
|---|---|---|
| Circuit Type | Dropdown | Limit type (SLC, NAC, etc.) |
| Address Start Override | Text | Starting address for this type |
| Quantity Limit | Integer | Maximum device count for this type |
| Quantity Threshold % | Percentage | Warning threshold (default 80%) |
Buttons
| Button | Action |
|---|---|
| Bulk Edit Selected... | Open the Bulk Edit Circuits dialog for selected circuits |
| Apply | Validate and save all changes |
| Cancel | Discard changes and close |
Validation
When you click Apply, the editor validates that:
- All circuits have cables assigned
- Default voltage values are set (20.4V if missing)
If validation fails, the grid scrolls to the first problematic row.
Tips
- Use the search panel at the top of the circuit grid to find specific circuits by name, panel, or part number
- Click the Default Color cell to open the AutoCAD color picker
- Select multiple circuits (Ctrl+Click or Shift+Click) and use Bulk Edit Selected... to modify common properties across all of them
- Circuit limits auto-filter to show only the selected circuit's limits
