Amplifier Kit

The amplifier kit (P/N 10-2773-X) is the heart of Fike’s Emergency Communication System (ECS). It is designed to feed a single audio zone and provide an integral 24 Vdc visual notification appliance circuit. The amplifier is capable of providing up to 50 watts of audio output power to connected voice evacuation speakers. The amplifier provides four (Class B) audio output circuits that are compatible with 25 or 70 Vrms speakers. An optional Class A card (P/N 10-2746) can be installed where redundant speaker circuit wiring is required. Each speaker circuit is capable of distributing the entire 50 watts of available amplifier power or the 50 watts can be distributed amongst all four circuits in any combination, as long as the 50 watts maximum is not exceeded.
