The Silent Knight SK-FFT is a fire-fighters telephone control panel that supervises, annunciates, and controls up to 24 remote telephone jacks right out of the box. One optional FFT-24 expander doubles capacity to 48 zones. Up to ten handsets can communicate simultaneously over the supervised circuit, and JumpStart auto-programming streamlines setup. Bright status LEDs show circuit, power, and trouble conditions at a glance. The SK-FFT mounts surface or flush (use trim ring VIP-TR for flush installs) and operates from any power-limited, filtered 24 V DC source.
