ATSET_OVERRIDE_ADDRESS |
Give one device a fixed address you choose |
Ribbon: FireCAD Tools > Circuits > Override Device Address
Prerequisites
- A FireCAD project must be open
- The device must be connected to the circuit you want to address it on
Overview
FireCAD addresses devices automatically, in wiring order. When one device needs a specific address, ATSET_OVERRIDE_ADDRESS fixes that device at the address you type. The other devices on the circuit keep being addressed automatically around it.
Steps
- Click Override Device Address on the Circuits panel, or type
ATSET_OVERRIDE_ADDRESS - At Select a device to override:, pick the device. A green marker shows which device you picked.
- If the device has more than one addressed connection, choose the one to override at Select device circuit address to override
- At Please type a new fixed device address
: , type the address (a whole number greater than 0) and press Enter - Press Escape to finish the command
The device's label shows the new address, and the devices after it on the circuit renumber to close the gap it left.
FireCAD will not give two devices on one circuit the same fixed address. If another device already holds the address you type, the command says That address is already locked by another device.
Overrides and locked addresses
An override and a locked address are the same thing: a fixed address stored for that device on that circuit.
| Override Device Address | Lock All Circuit Addresses | |
|---|---|---|
| What it fixes | One device, at the address you type | Every device on the circuit, at the address it has now |
| Removed by | Remove Override (ATREMOVE_OVERRIDE_ADDRESS) or Unlock All |
Unlock All |
Because they are stored the same way, Unlock All Circuit Addresses also removes every override on that circuit. Set the overrides again afterwards if you still need them.
Tips
- Remove the override before you disconnect the device; otherwise its address stays reserved on the circuit
- To return a device to automatic addressing, use Removing Address Overrides
- To fix a loop that is wired in a different order, change the wiring order with Resequence Circuit rather than overriding addresses one by one
