Edwards EST3 3-ZA20A-E Zone Amplifier, Class A 20 V
Product Code: 3-ZA20A-E
EST3 Class A amplifier serving an announcement zone on the voice evacuation side. When a break occurs in the Class A speaker line, broadcast continues from the other end of the line; this prevents a single cable fault from leaving an entire floor silent. The number of zones and speaker load determine the number of amplifiers required.
