INSTALLATION AND OPERATING INSTRUCTIONS
APPLICATION:
The DG-12II “Duress Guard” audio alarm Base Station is a sound activated
12 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-12II rear panel. A tester for alarm delay
and audio is built into the DG-12II. The DG-12II will work with all Louroe
microphones and speakers. Two-way talk/listen is accomplished with the
addition of a DG-MA Monitor/Talkback Amplifier.
QUICK REFERENCE:
Wiring Requirements:
If using microphones for one-way / listen-only:
2 Conductor shielded cable, 22-gauge with a 24-gauge drain wire.
West Penn 452 or equivalent
NOTE: Unshielded cable is not recommended for
microphone connections.
If using speaker/microphones for two-way listen/talkback:
4 Conductor (all within the same jacket):
Microphone Connection: 2 Conductor shielded, 20-gauge with a
22-gauge drain wire.
Speaker Connection: 2 Conductor unshielded, 18-gauge

PAGE 2 of 28
DESCRIPTION:
The DG-12 Audio Alarm Base Station is of panel construction and mounts in a standard 19”
equipment rack. All controls and indicators are mounted on the front panel and all electrical
connections are made at the rear of the unit. DC power is supplied to the DG-12II by an
external power supply unit (included), which connects to 120 VAC.

[1] Zone Selector Switch Selects monitor or talkback operation for that zone. Zone numbers
are located directly above the switches (zones 1-12).
[2] Alarm Indicator LED Lights red when the unit goes into alarm. Stays red until the reset
button is pressed. Lights green (flickers) when audio is detected.
[3] Power Indicator LED Lights when power is applied to the unit.
[4] Sonalert Buzzer Gives a 3 second pulsating audible sound whenever the unit goes
into alarm. Located on side of chassis. May be turned OFF using
the Keyswitch[16].
[5] Time Delay Switch Selects to increase or decrease the length of alarm delay.
Switch operations:
a). UP position- increases the length of alarm delay
b). DOWN position- decreases the length of alarm delay.
[6] Audio Alarm Input Jack Used for testing the level of audio coming into the unit as seen from
the Audio Level Indicator[17].
[7] Threshold Sensitivity Switch Selects to increase or decrease the audio threshold sensitivity
settings. Used in conjunction with the Day/Night Sensitivity
Switch[9],Night Sensitivity Setting Pushbutton[20] and Day
Sensitivity Setting Pushbutton[21] (see next page).
Switch operations:
a). UP position- increases the sensitivity of audio threshold settings
b). DOWN position- decreases the sensitivity of audio threshold

[9] Day/Night Sensitivity Switch Selects day or night sensitivity.
Switch operations:
a). UP position- selects night sensitivity. Used in conjunction with the
Night Sensitivity Setting Pushbutton[20].
b). DOWN position- selects day sensitivity setting. Used in
conjunction with the Day Sensitivity Setting Pushbutton[21].
[10] Tester Trigger Pushbutton Used to initiate a test alarm to set and determine the length of the
alarm time delay setting as shown by the Alarm Delay Indicator[18].
[11] Tester Reset Pushbutton Resets Alarm Delay Indicator[18].
[12] Reset Switch Resets all zone alarms simultaneously.
[13] Tester Power Switch Turns ON power to the tester section of the unit.
[14] Non-Alarm Monitor Switch Used to listen or monitor any or all the zones even when no alarm
has occurred. Audio from any or all zones that have been switched to
“monitor” (Zone Selector Swtches[1] in UP position) can be
monitored at the Monitor Speaker[36] located in the DG-MA unit.
[15] Auto-Reset Knob Cancels the alarm after a set period of time and returns the unit in
standby mode. Time can be set from 3 seconds to 3 minutes. Turn
knob clockwise to ON position. Continue rotating to desired time
setting.

[17] Audio Level Indicator Shows the level of the audio of the zone in test, It contains 10 level
segments (7 green and 3 red) that illuminate and move up and down
the scale, depending upon the amount of signal it receives. Settings
should be made so that the level of the ambient sound on test does
not reach the red segments. The unit will go into alarm when the
audio reaches the last red segment.
[18] Alarm Delay Indicator Indicates the length of the alarm delay setting.
[19] Alarm Delay Setting Pushbutton Used to set the length of alarm delay. The switch can be pushed to
a maximum of 32 times. It must be pushed and released quickly.
The switch will go to the next step or more if not released
immediately.
[20] Night Sensitivity Setting Pushbutton Used to set the audio threshold sensitivity for nighttime. The
Day/Night Sensitivity Switch [9] must be in the UP position. The
switch can be pushed to a maximum of 32 times. Additional pushes
have no effect on the switch.
[21] Day Sensitivity Setting Pushbutton Used to set the audio threshold sensitivity for daytime. The
Day/Night Sensitivity Switch [9] must be in the Down position.
The switch can be pushed to a maximum of 32 times.
[22] Audio Alarm Output Jack Provides DC output corresponding to the audio alarm level after the
filter network. Used to set and test the level of audio as seen at the
Audio Level Indicator [17]. A test cable is provided to connect
between this jack and Audio Input Jack[6].
[23] Alarm Delay Output Jack Provides output to the Alarm Delay Input Jack[8]. Used to set the
time delay feature and for checking the time delay setting, which is
variable between 0.1-3.2 seconds.
