DG-25 III Sound Activated Alarming Audio Base StationSpecial OrderThe DG-25III is a twenty five zone alarming
base stations designed to provide sound activated audio monitoring. As a
system, it is interfaced with Louroe microphones or speaker/microphones
mounted in remote locations. Each zone has a variable threshold level
based on frequency and sound pressure, and a variable alarm delay (from
0.1 to 3.2 seconds) that can be set by the installer or owner. When a
sound or disturbance exceeds the pre-set threshold level and time
duration, the unit goes into alarm. A lighted LED and three second tone
identify the zone, along with a relay contact for activating a camera or
other annunciation. Requires companion DG-MA for two-way
listen/talkback or DG-Monitor for one-way listen. Can be cascaded up to
250 zones with total of 10 DG-25III base stations. Only one DG-MA or
DG-Monitor is required.
