WIRING REQUIREMENTS
2 conductor shielded, 22 gauge, with a 24 gauge drain wire.
West Penn 452 or equivalent
MICROPHONE INSTALLATION - MECHANICAL
Verifact A Microphone is designed for surface mounting to a ceiling or wall. Microphone will pick up
®
sounds 15’ away from all directions. For best results, install microphone as close to desired area of
coverage as possible. Avoid mounting microphone to ceiling heights in excess of 10’, or near air
vents, refrigeration units, or other audio interferences.
NOTE: Make wiring connection on back side of microphone before installing microphone to ceiling or
flat surface.
MICROPHONE INSTALLATION - ELECTRICAL
Located on back side of microphone is a terminal block marked A, B and C.
A is 12 Vdc
B is Audio
C is Ground (common)
Using recommended wiring, connect as follows:
RED wire to terminal A (12Vdc)
BLACK wire to terminal B (Audio)
BARE wire to terminal C (Ground)
NOTE: If using wiring from other manufacturers,
color code may vary.
MS-1 MECHANICAL INSTALLATION
The MS-1 (Mute Switch) fits in a single gang electrical box for flush or surface mounting to a wall.
Electrical connection is thru a 3 Pin Terminal block.

INSTALLATION AND OPERATING INSTRUCTIONS
MECHANICAL INSTALLATION - MODEL IF-1 INTERFACE ADAPTER
The IF-1 Interface Adapter serves as an interface device between the microphone and the audio receiver
(DVR/VCR, PC sound card, etc.). The IF-1 can be installed several ways:
1) Wall mounted close to DVR/VCR or IP Network Camera, etc.
2) Attached to side of the receiving device using two-way ¼” adhesive tape
(not provided)
MICROPHONE CONNECTION TO IF-1 INTERFACE ADAPTER VIA THE MS-1 (See
interconnection diagram on the next page)
Connect 2 cond shielded cable to the microphone terminal block as follows:
a. Using recommended cable, connect black wire to terminal B of microphone.
b. Connect bare (ground) wire to terminal C.
c. Connect red wire directly to terminal A of the MS-1 using a wire nut from a second 2 cond cable.
d. Connect the other end of this cable to IF-1 (red to terminal A; black to terminal B; and bare to
terminal C)
Using the second 2 cond shielded cable;
a. Connect red wire to terminal A of the MS-1 (the other end of this wire is connected to the first 2
cond cable mentioned above on “c”)
b. Connect black wire between terminal B of MS-1 and terminal A of microphone.
c. Connect both ends of bare wire to terminals C of microphone and MS-1
To apply power to the system, Model AD-1 12Vdc power supply is included. First connect small end (female
90° plug) into 12Vdc jack on IF-1, then connect 2-prong power block to a standard 110Vac outlet
or power strip.
NOTE: Model IF-1 contains two types of audio outputs. A connection cable is provided for each type.
1) RCA
2) 3.5mm stereo
3) RCA to 3.5mm mono with adaptor
These two audio outputs are in parallel ... only one can be used
CONNECTION BETWEEN IF-1 INTERFACE ADAPTER AND DVR/VCR WITH RCA TYPE AUDIO
CONNECTIONS
To make connection to DVR/VCR, plug the RCA cable (supplied) into the RCA type audio output jack located
on the output side of Model IF-1. Connect other end of RCA cable to the DVR/VCR’s “AUDIO IN” jack.
CONNECTION BETWEEN IF-1 AND AN IP NETWORK CAMERA, DVR, VIDEO SERVER WITH
3.5mm MONO TYPE AUDIO CONNECTIONS
To make connection to IP Network Camera, plug the RCA to 3.5mm mono cable with adaptor (supplied) into
the RCA audio out jack located on the output side of IF-1, connect other end of cable (3.5mm) to the camera’s
audio in jack.
CONNECTION BETWEEN IF-1 AND A DVR, IP NETWORK CAMERA OR PC SOUNDCARD WITH
3.5mm STEREO TYPE CONNECTION.
To make connection, plug the 3.5mm stereo cable (supplied) into the “audio out” jack located on the output
side of IF-1. Plug the other end of the cable to “AUDIO IN” of DVR, IP Network Camera or “ LINE IN” of PC
soundcard.

INSTALLATION AND OPERATING INSTRUCTIONS
OPERATION
With the addition of the MS-1 (Mute Switch), the microphone audio can be muted if not needed. Turn On the
rocker switch on the MS-1 to activated the audio of the microphone. The built-in red light on the switch will light
indicating that the microphone is live and audio is present at the IF-1. If the output of the IF-1 is connected to a
receiver such as a DVR, Video Encoder or IP Camera, audio is present on the input of these receivers.
Turning OFF the MS-1, will turn OFF the audio from the microphone and the built-in light on the switch is not
lighted.
SENSITIVITY SWITCH OF MICROPHONE
For special installations that require less microphone sensitivity, a sensitivity switch has been added
to the microphone pre-amp (PC board) and has two positions - N and L:
N represents normal sensitivity (0dB output into 600W)
L represents low sensitivity (-6dB output into 600W)
NOTE: Louroe™ Verifact microphones are always shipped with the sensitivity switch in
normal (N) position. Do not change unless required.
To make an adjustment, use a small screwdriver and move slide switch from N to L. Sensitivity
switch is located on the backside of Verifact™ A Microphone.
