Manual

APPLICATION:
The DG-25III “Duress Guard” audio alarm Base Station is an upgraded
version of the DG-25 Special. It is a 25 zone audio surveillance system,
which provides audio and visual alarms when sound levels exceed the
preset threshold, time duration and frequency band in a given zone.
It is designed for life and property protection by monitoring areas of possible
crime or violence. When coupled to the DG-MA Monitor/Talkback Amplifier,
the operator may speak and listen to any or all surveillance zones, as
selected on the front panel. An audio mixer such as Louroe's MLA-6 may
be used to expand the area of coverage per zone. Up to 6 microphones
per zone may be used.
Provisions for audio output to a recorder and alarm relay closures for other
equipment are available at the DG-25III rear panel. A tester for alarm
delay and audio is built in to the DG-25III. The DG-25III will work with all
Louroe microphones and speakers. Two-way talk/listen is accomplished
with the addition of a DG-MA Monitor/Talkback Amplifier.
