OPERATION:
The DG-12 Audio Alarm Base Station is normally paired with the DG-MA
Monitor/Talkback Amplifier for utilizing the monitor and talkback capabilities of the unit.
The operation below includes the DG-MA unit.
The Keyswitch[14] has three functions. At position 1, it turns “OFF” the power to the
DG-12II. At Position 2, it turns “ON” power as indicated by the Power Indicator LED[3].
At Position 3, it turns “ON” the Sonalert Buzzer[4] while the power is still “ON”. The key
can be pulled out at any of these positions for security purposes.
When a microphone picks up sound within its vicinity, the bi-color zone Alarm Indicator
LED[2] will start to glow “green”. The brightness depends on the intensity and type of
audio the microphone is picking up. As long as there is noise present near the
microphone, the green light will continue to blink. This would signal the operator that
somebody is out there in that particular zone. When the audio exceeds the threshold
level setting. the unit will go into alarm. At this time, the Alarm Indicator LED[2] for that
zone will change color from “green” to “red” indication an alarm condition and produce a
3-second audio alert from the Sonalert Buzzer[4]. When the alarm has occurred the
audio from that zone can be monitored on the DG-MA Monitor Speaker[36] or
headphone by moving the alarmed Zone Selector Switch[1] to “monitor” (UP position).
Monitor level is adjusted with the Monitor Level Control Knob[34] on the DG-MA panel.
The alarm is canceled by pressing the Reset Switch[12].
Selecting the “monitor” position for one or more zones allows the audio to be monitored
without an alarm occurring when the Non-Alarm Monitor Switch[14] is in the “ON”
position. The level is controlled by the Monitor Level Control[34] on the DG-MA.
When a Zone Selector Switch[1] is in the “monitor” position (UP) and an alarm occurs,
audio is immediately present on the built-in Monitor Speaker[36] or optional
Headphones[34].
Alarm threshold settings can be adjusted by pushing the Night Sensitivity Setting
Pushbutton[20] or Day Sensitivity Setting Pushbutton[21]. The Day/Night
Sensitivity Switch[9] selects which sensitivity setting pushbuttons are active. When
the Day/Night Sensitivity Switch[9] is in the UP position, all the Night Threshold
Sensitivity Switches[20] are activated. The switches can now be adjusted to their
proper settings. When the Day/Night Sensitivity Switch[9] is in the DOWN position, all
the Day Threshold Sensitivity Switches[21] are activated. The sensitivity setting
pushbutton switches are factory preset to a certain threshold. This can be used as a
reference setting.
The Alarm Delay Setting Pushbutton[19] is factory set to 0.1 second (minimum or no
delay). It can be adjusted to the desired time (up to 3.2 seconds) by placing the Time
Delay Switch[5] UP and pushing the Alarm Delay Setting Pushbutton[19] one step at
a time to increment the increase. The DG-12II can be triggered using the Tester Trigger
Pushbutton[10] to determine the alarm delay as seen on the Alarm Delay
Indicator[18].
Talkback to a given zone is accomplished by plugging the provided handheld microphone
into the AUX MIC Jack[30] on the DG-MA front panel and holding down the respective
Zone Selector Switch[1]. To talk to all zones at once, press the All Call Pushbutton
Switch[33]. The volume of the talkback audio present at the zone is set to the Talkback
