Spec Sheet

DESCRIPTION
Model DG-12II is a 12 zone alarming sound activated audio
monitoring base station. When combined with companion
unit DG-MA (Listen/Talkback Amplifier) and interfaced with
remote speaker/microphones, it provides a sound activated
duress audio system with two-way communications. Each
zone has a variable threshold level control, based on
frequency and sound pressure level, and a variable alarm
delay (from 0.1 to 3.2 seconds) that can be set by using the
built-in tester(included) for alarm audio and time delay.
The time delay feature is effective in reducing false alarms.
The DG-12II is supplied with 12 zone cards. When a
sound or disturbance occurs that is below the preset
threshold level, the nearest microphone detects the sound
and identifies the zone with a lighted LED that blinks
GREEN. If the sound increases, the LED intensifies to a
solid GREEN. If it exceeds the preset threshold, the zone
goes into alarm, with the zone LED changing to RED, along
with a 3 second beep. A relay contact closes to activate a
camera or other annunciation. The person at the remote
station can communicate hands-free with personnel at the
base station. The person at the DG-12II can talk/listen with
the remote station by pressing the zone switch. Talkback to
the remote station is with a hand-held microphone
(provided) that is connected to the companion DG-MA
Listen/Talkback Amplifier. Zone alarm can be cancelled by
automatic or manual reset feature. Automatic re-set can run
between 3 sec and 3 minutes. All LOUROE Microphones
(A, B, C, D, D-V, E, K and L-DT) and all
Speaker/Microphones (Models TLI, TLM, TLMC, TLO,
TLSP and TLSP-PB) are compatible with the DG-12II.
