INSTALLATION AND OPERATING INSTRUCTIONS
DESCRIPTION
®
ASK-4 #304 is a four zone audio monitoring system
designed for direct connection to a DVR, PC soundcard or
IP Network Camera. Model IF-4 Interface Adapter (usually
mounted near the recording device) receives the wiring from
the Verifact™ A Microphone, supplies power and drives the
audio signals into the DVR, IP Network Camera, Video
Server or PC Soundcard.
Distance between the Verifact A Microphone and Model IF-
®
4 Interface Adapter may be up to 1,000 ft.(305m) using
recommended wiring. Each output of the IF-4 has an audio
level control to increase or decrease the level of audio output
going to the receiving device.
AD-1 POWER SUPPLY
KIT CONTENTS
4 VERIFACT Model A Microphones
Model IF-4 Audio Interface Adapter
Model AD-1 12Vdc power supply
Patch cables for connection to the audio inputs of
DVR’s, IP Network Cameras, Soundcards, etc. as listed
above (RCA to RCA and RCA to 3.5mm Mono adaptors)

WIRING CONNECTIONS
MICROPHONE CONNECTIONS
Located at the bottom of the Verifact A microphone is a 3-pin terminal block marked A, B, and C.
A = 12Vdc power
B = Audio output of microphone
C = Ground
If using the recommended wiring (West Penn 452), connect as follows;
Red wire goes to terminal A of microphone
Black wire goes to terminal B of microphone
Bare wire goes to terminal C of microphone
After all microphones have been connected, bring the other end of the cable to the IF-4 location and connect each
microphone to the corresponding terminal block of the unit matching A to A, B to B, and C to C. Be sure to properly match
wire colors. If using cable from other manufacturers, color code may vary.
CONNECTIONS BETWEEN IF-4 AND DVR (OR OTHER AUDIO RECEIVING DEVICE)
Connect the RCA outputs of the IF-4 to the corresponding audio inputs of the receiving device. RCA and RCA to 3.5mm
mono cables are included in the kit.

APPLYING POWER TO THE IF-4
Included with the IF-4 is a power supply (120V/12Vdc). Connect the small end of the 90° female plug
into the 12Vdc jack, located on the input side. Then connect the two-prong large end into a standard
110/120V electrical outlet.
Turn ON/OFF power switch, located behind green power LED to ON position. The green LED will
illuminate, indicating power to the system. The system will now provide audio to the DVR, Soundcard
Module, IP Network Camera, etc.
AUDIO LEVEL ADJUSTMENT
Located on the input side are potentiometers (round, with adjustment arrow) for each microphone.
This is for adjusting the audio gain and to prevent overdriving or underdriving the audio signal.
The adjustment arrows are shipped in the straight-up position. Turn slowly counterclockwise to lower
the gain, and clockwise to increase. This will provide the desired level of audio signal into the Audio
Receiving Device (DVR, Soundcard Module, etc.). A full turn clockwise increases the gain to 10dB. A
full turn counterclockwise will decrease the gain -30dB.
AUDIO TEST SWITCH
The purpose of this switch is to indicate the presence of audio and to assure the user that the IF-4 is
driving the audio signals into the audio input of receiving device (DVR, IP Network Camera, Video
Server, Soundcard module, etc.)
INSTALLATION AND OPERATING INSTRUCTIONS
Located on the audio output side of IF-4 is a DIP switch labeled Audio Test Switch. To the left of the
switch is a red LED marked Audio Indicator.
For testing:
1) Select a zone that has a microphone connected to the microphone terminal block.
IF-4 utilizes pins 1-4.
2) Push pin to the ON position. The red LED will illuminate, indicating audio is present.
With short bursts of audio, the LED will flicker and with continuous flow of audio LED
illumination is constant. Only one microphone can be tested at a time
NOTE: When testing is complete, all pins of the DIP switch must be in
the OFF (down) position.
