WIRING CONNECTIONS

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.

2 Conductor shielded cable, 22

gauge with a 24 gauge drain wire

WIRING REQUIREMENTS

West Penn 452 or equivalent

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.
