INSTALLATION AND OPERATING INSTRUCTIONS OPERATION: The DG-25III Audio Alarm Base Station is normally paired with the DG-MA Monitor/Talkback Amplifier for utilizing the monitor and talk back capabilities of the unit. The operation below includes the DG-MA unit. The Keyswitch[16] has three functions. At position 1, it turns “OFF” the power to the DG-25III. At position 2, it turns “ON” power as indicated by the Power Indicator LED[3].
INSTALLATION AND OPERATING INSTRUCTIONS OPERATION (cont.): 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 heard at the zone is set by the Talkback Level Control [31] on the front of the DG-MA.
INSTALLATION AND OPERATING INSTRUCTIONS INSTALLATION-Electrical: All electrical installations are made at the rear of the unit. MICROPHONE CONNECTIONS: Connect WEST PENN 356 (sample cable used) to remote station such as a Louroe TLI as shown in Fig. 3 below. Connect the 3 wires wrapped with a shield to microphone terminals marked “A”, “B”, and “C”. Red to “A”, black to “B” and bare or drain wire to “C”. Connect the other two unshielded cables to speaker 70V transformer .

INSTALLATION AND OPERATING INSTRUCTIONS CONNECTIONS TO PLUG-IN CONNECTOR (AUDIO): Prior to connecting the microphone cables to the DG-25III plug-in connectors, each microphones should be checked for proper operation. This can be done quickly by connecting the Louroe PTA (portable test amplifier) to each microphone cable. The battery powered PTA powers the microphone under test and monitors its output though the installed cabling. This eliminates any faulty microphone circuits before final testing.

Both control blocks of the DG25III and DG-MA are marked “1,2,3,4,5”. Connect terminal “1” of DG-25III to terminal “1” of DG-MA.
INSTALLATION AND OPERATING INSTRUCTIONS CONNECTION TO A DVR, VCR OR OTHER RECORDING DEVICE: Remove the jumper (fig 9A) that connects the Audio Input Jack[38] to the Audio Output Jack [39] located at the rear of the DG-MA. Using a dual RCA cable, connect the Audio Input Jack[38] of the DG-MA to the Audio Output Jack of the recorder. Connect the Audio Output Jack[39] of the DG-MA to the Audio Input Jack of the recorder. See Fig. 9 below.
INSTALLATION AND OPERATING INSTRUCTIONS CONNECTION TO AN AUDIO MIXER/COMBINER: Up to six microphones or four speakers can be installed in one zone by using Louroe MLA-6 audio mixer;/combiner unit. See Fig. 10 for connecting speaker/microphone combination units and Fig. 11 for microphone only unit. Fig. 10 shows connection for only one speaker/microphone unit. Additionally, up to 6 microphones and 4 speakers can be installed to this unit by connecting the microphone cables to inputs “MIC 2” through “MIC 6”.
