The SA-CLA adds Class A NAC wiring capability to control panels that ship Class B only, giving the notification circuit a return path so a single wire fault doesn't take down the whole zone.

Built for the commercial fire installer

It plugs directly onto the main circuit board using integrated plastic standoffs — no ribbon cable or separate enclosure — and its terminal block handles the NAC return wiring. On panels like the FX-64, Class A wiring is only available with this card installed, so it's the difference between a Class B-only job and one that meets a Class A NAC spec.

  • Adds Class A return-path wiring to NAC circuits on supported panels
  • Plugs directly onto the main board with plastic standoffs — no ribbon cable
