WIRING CONNECTIONS BETWEEN MODEL TLM-W SPEAKER/MICROPHONE AND AP-1TB AUDIO BASE
STATION

1) Connect one end of recommended cable to remote speaker/microphone (TLM-W) as shown in Fig. 4. Connect wires
wrapped with overall shield to terminals “A”, “B”, and “C” of TLM-W’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 (twisted pair) green and white to green and white wires of TLM-W’s 70V transformer.
Using wire nut connect green wire to green wire of TLM-W’s 70V Transformer. Again, using wire nut connect white
wire to white wire of TLM-W’s 70V Transformer.

3) Connect the other end of the cable to AP-1TB Mic 6-Pin Terminal Block [14]. Make sure that wire connected to
terminal “A” of remote TLM-W connects to terminal “A” of AP-1TB’s Mic 6-Pin Terminal Block [14]; wire connected
to terminal “B” of TLM-W connects to terminal “B” of AP-1TB; “C” to “C”. Observe cable color coding. Terminal “P” of
AP-1TB is not used with this application. Used only when paralleling to a second AP-1TB.

4) For speaker connection connect green speaker wire (positive) to Mic 6-Pin Terminal Block [14] terminal “SP”,
connect white speaker wire (ground) to “G”.

5) When a recording device is used (DVR,VCR,etc.) connect Audio-OUT Jack [16] to recorder’s Audio-IN Jack with the
dual RCA cable (supplied).

6) Connect Audio-IN Jack [15] to recorder’s Audio-OUT Jack with the remaining RCA plug.

d. Drill an opening at a convenient location on backbox for passing wire or for conduit connection.

OPERATION AND TEST

1) Applying Power To The System

With all wiring connections complete, power up the system using the 24Vdc, 1A or 24 Vdc, 1.5A power supply included

with the kit. First connect the small end of power supply to the 24V DC IN jack [18] located on rear panel of AP-1TB
Base Station. Connect the large end with the 2-prong plug to a standard 120Vac wall outlet or power strip.

Have someone create sound by talking (or use a radio) at the remote Model TLM-W Speaker/Microphone. Audio
should be present via the AP-1TB’s Monitor Speaker [13]. Adjust speaker volume by rapidly pressing and releasing
the Monitor Volume Up Control Switch [5] to increase volume, or monitor Volume Down Control Switch [4] to
decrease volume.

4) Talkback Mode

To speak out to the remote TLM-W, press and hold down Talkback Switch [3] of the AP-1TB. Another person is

needed to listen at the TLM-W location. If talkback volume needs adjusting, rapidly press and release the Talkback

Volume Up Control Switch [7] to increase volume. Rapidly press and release Talkback Volume Down Control
Switch [6] to decrease volume.

a color coded dual RCA connector cable. RCA plugs are usually red and gray.

For recording take one end of dual RCA cable (red) and connect to Audio Out Jack [16] of AP-1TB. Connect other
end (same color) to Audio In of the recording device (DVR, VCR, etc.). For listening to recorded playback through the

AP-1TB, connect RCA plug into Audio Out of the recording device and the other end of RCA plug to Audio-In Jack [15]

of AP-1TB. Press DVR/VCR Playback Switch [2] to activate playback mode (Playback Indicator LED [10] will
illuminate) AP-1TB’s speaker will produce recorded audio playback.

As an option, recorded audio may also be played back through a CCTV monitor with built-in amplifier or through the
DVR’s built-in audio system.
