If DVR has only one audio input, connect the “Audio Out” jack on
back panel of AP-12TB/AP-16TB to “Audio In” of DVR using an RCA
cable.
If DVR has multiple audio inputs, connect the “Mic Out” jacks on
back panel of AP-12TB/AP-16TB to the audio inputs of DVR using RCA

WIRING CONNECTIONS
1). Connect one end of cable to remote speaker/microphone as shown in Fig. 3. Use 4 conductor
shielded audio cable such as West Penn 356. Connect wires wrapped with overall shield to
terminals “A”, “B”, and “C” of microphone’s terminal block. When using West Penn 356, connect red
wire to terminal “A”; black wire to terminal “B” and bare wire to terminal”C”.
2). Connect the two speaker wires (white and green) to speaker’s 70 volt transformer terminals.
Connect cable’s white wire to white wire connected to the 70 volt transformer using a wire nut.
Connect cable’s green wire to green wire of transformer with a wire nut.
3). Connect the other end of the cable to AP-12TB or AP-16TB Mic 5-Pin Terminal Block[14] for the
zone which the remote microphone is assigned. Make sure that wire connected to terminal “A” of
remote microphone connects to terminal “A” of unit’s Mic 5-Pin Terminal Block[14]; wire connected
to terminal “B’ of microphone connects to terminal “B” of unit’; “C” to “C”. If using wire from other
manufacturers, color code may vary.
4). Connect white speaker wire to Mic 5-Pin Terminal Block[14] terminal “G”. Connect green wire to
terminal marked “SP”.
5). Repeat steps 1 thru 3 for zones 2, 3, 4 .....16.
6). When a recorder is used (DVR, VCR etc.), connect Audio-OUT Jack[15] to recorder’s Audio-IN
Jack with an RCA cable (not supplied).
7). Connect Audio-IN Jack[17] to recorder’s Audio-Out Jack.
8). Plug AC Adapter (supplied) to DC-IN Jack[20].
NOTE: If AP-12TB or AP-16TB is to be used as a one-way listen only system (no talkback), any Louroe
Verifact Microphone can be used. Make microphone connections as described above (see step 1).
Disregard speaker connections. Use 2 conductor shielded cable, 22 gauge with a 24 gauge drain.
West Penn 452 or equivalent. Same color code as in West Penn 356 (red, black and bare).

OPERATION AND TEST
1). To apply power, first connect small end of 24 Vdc power supply to the 24 Vdc power jack located
on rear panel , then plug power block into a standard 120 Vac wall outlet or power strip.
2). Turn on power to the unit by rotating the Power-Volume Control Knob[9] clockwise to “ON”
position. Filter-OUT Indicator[2] should light green, indicating power is present at the unit. Rotate
Power-Volume Knob[9] further clockwise to increase the level of loudness of monitored audio.
3). Press Zone Selector Switches[1] marked zone 1. Audio from zone 1 should be present at the
Monitor Speaker[13]. If there is no audio, temporarily remove wires connected to Mic 5-Pin
Terminal Block[14] for zone 1 located at the rear of the unit. With a voltmeter, check that 12 Vdc is
present at terminals “A” and “C”. Place positive lead of voltmeter to terminal “A” and negative to
“C”. If voltage is not present, unit has defective voltage regulator. If voltage is present, check to
see if the wires are connected properly to the right terminals. Otherwise microphone is defective.
Call factory for assistance.
4). Press Talkback Switch[8] and speak into the Talkback Microphone[10]. Rotate Talkback Volume
Control[12] clockwise to increase the level of talkback audio. Another person is needed at the
remote location to listen to the volume and clarity of talkback audio.
5). Repeat steps 3 and 4 for the other zones.
6). When a 24 hour VCR is connected to the unit, press VCR Switch[7]. VCR-IN Indicator[4] will light
yellow. Start recording live audio. It is not necessary to use VCR switch if recording into a DVR.
The VCR Switch[7] must be in the “OUT” position when a recorder is not connected to the unit.
Otherwise live audio will be muted.
7). Recorded audio can be played back through the AP-12TB/AP-16TB’s built-in amplifier and
speaker. If audio playback is from a 24 hour time lapse recorder, press Filter Switch[6] to 12/24
hour mode. Filter In indicator[3] will illuminate red. If playback is from a DVR, filter switch is not
used and should be in the “OUT” position. If no recording device is used, then filter switch must be
in the “OUT” position. Otherwise live audio will be muted. The green LED will illuminate when filter
switch is in the “OUT” position.
