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.
