## What is Candela FD?

Candela FD is a professional NAC (Notification Appliance Circuit) voltage drop calculator built for fire alarm
  technicians, engineers, and inspectors.

  Quickly determine if your circuit design will deliver adequate voltage to every notification appliance on the run.
  Candela FD uses conservative UL max current ratings — not typical manufacturer values — so your calculations meet code
  compliance standards.

  CALCULATOR
  - Select wire gauge (12, 14, 16, or 18 AWG)
  - Enter wire run length, panel voltage, and minimum operating voltage
  - Add devices from a built-in database of real notification appliances
  - Adjust quantities and override mA values per device on the fly
  - Instantly see voltage drop, end-of-line voltage, and pass/fail status

  DEVICE DATABASE
  - 89+ notification appliances from major manufacturers
  - System Sensor, Wheelock, Edwards/EST, Gentex, Bosch, Potter, Siemens, and Hochiki
  - Horns, strobes, horn/strobes, and speakers
  - Browse by manufacturer or search by model number
  - UL max current ratings for code-compliant calculations

  BUILT FOR THE FIELD
  - Works completely offline — no internet required
  - Dark interface designed for readability on job sites
  - Fast, focused, no account required

  Built by Prossess.
