INSTALLATION AND OPERATING INSTRUCTIONS

MECHANICAL INSTALLATION OF TLM-W SPEAKER/MICROPHONE

The TLM-W can be mounted on its plastic backbox for surface mounting or to a standard 3 gang electrical box for flush
mounting to a wall.

When using the plastic backbox, drill the box with an opening the size of the desired conduit where the cable will pass
through. If surface mounting to a 3 gang electrical box is needed, install the box inside the wall and screw in the faceplate
after the wires are all installed.

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. 3. Connect wires
wrapped with overall shield to terminals “A”, “B”, and “C” of TLM-W’s terminal block. When using sample cable,
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 [12]. 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 [12]; 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 AP­1TB 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 [12] terminal “SP”,
connect white speaker wire (ground) to “G”.

5) When a recording device is used (DVR,VCR,etc.) connect Audio-OUT Jack [11] to recorder’s Audio-IN Jack with the
dual RCA cable (supplied).

6) Connect Audio-IN Jack [10] to recorder’s Audio-OUT Jack with the remaining RCA plug.

7) Plug AC Adapter power supply (included) to DC-IN Jack [18].

INSTALLATION AND OPERATING INSTRUCTIONS

OPERATION AND TEST

1) Applying Power To The System

With all wiring connections complete, power up the system using the 12Vdc, 500mA power supply included with the kit.

First connect the small end of power supply to the DC IN Jack [13] 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.

2) Rotate the Power-Volume Control[1] ON position as indicated by the Power LED[3] Power LED [3] will illuminate.

3) Testing For Listen And Talkback At The AP-1TB Base Station - Listen Mode

Push in Zone Switch [4] located on front panel of AP-1TB. Zone Switch[4] will illuminate (blue) and two-way

communication is now activated. Have someone create sound by talking at the remote Model TLM-W
Speaker/Microphone. Audio should be present via the AP-1TB’s Monitor Speaker [9]. Adjust loudness of sound heard
at the Monitor Speaker[9] by rotating the Power-Volume Control[1] clockwise to increase or counterclockwise to
decrease.

4) Talkback Mode

To speak out to the remote TLM-W, press and hold down Talkback Switch [8] of the AP-1TB. Another person is

needed to listen at the TLM-W location. If talkback volume needs adjusting, rotate Talkback Volume Control[7]
clockwise to increase or counterclockwise to decrease.

5) Audio Recording And Playback

Model AP-1TB contains an Audio Out Jack [11] and an Audio In Jack [10], located on rear panel. Included with kit is

a color coded dual RCA connector cable.

For recording, take one end of dual RCA cable (red) and connect to Audio Out Jack [11] 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 [10]

of AP-1TB. Push in Playback/MuteSwitch [6] to activate playback mode. Playback/Mute Switch[6] will illuminate
(orange).The unit is now ready to receive audio from the recorder. Press playback on the recorder. Recorded audio can
now be heard at the AP-1TB Monitor Speaker[9].This switch must be turn OFF if not being use for playback as the
same switch can be used for muting the audio heard at the Monitor Speaker[9] when monitoring audio.

This switch can be used either for muting the sound of the remote microphone heard on the unit’s speaker or listening

for playback audio from a recorder.
