The Silent Knight SKE-B450 is the 50-watt voice evacuation amplifier board used inside the SKE-450 Voice Evacuation Control Panel. This part ships as the bare board with the installation manual.
First, the board delivers 50 watts of audio output. Then it drives one speaker circuit at either 25 VRMS or 70.7 VRMS. In addition, the speaker circuit can be wired Class A or Class B.
What the Silent Knight SKE-B450 Does
