The LE-175 Monitor/Talkback Amplifier is a companion to model DG-12II and DG-25III alarming base stations. It provides two-way listen/talkback communications between the base station and the remote speaker/microphones in the audio system. "All Call" feature allows security personnel to address all zones simultaneously. One LE-175 will support up to 10 DG-25III base stations for a total of 250 zones. For audio systems larger than 25 zones, an external amplifier is recommended. This will boost "All Call" capabilities. A hand-held microphone for talkback and "All Call" is provided. The LE-175 is standard EIA 19" rack mountable.
