The DG-12II is a twelve 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 levelbased 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 lightedLED 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.
