NAPCO Veri-Phone User manual

INTRODUCTION
Veri-Phone is a programmable two-way voice module that allows on-line (live) communication between a central
station and the premises. To simplify installation, the Veri-Speaker consists of a siren, microphone and speaker in
one compact unit. With only 4 wires, hookup is easy and convenient. See WI783 for more information regarding
the operation and triggering methods for your control panel.
WIRING THE VERI-SPEAKER TO THE VERI-PHONE MODULE
Connect the Veri-Speaker wires as shown in the table below and diagram on the following page.

Red 12V (+) 1 +12 Volt power input. Requires 350mA for siren, and 20mA for micro-
phone and speaker.

Gain adjustment located at upper right of opened Veri-Speaker unit.
RECOMMENDED INITIAL SETTINGS
1. Please note there are two microphone gain potentiometers, one on the Veri-Phone, and one on the Veri-
Speaker. For initial setup, it is recommend to set the microphone gain potentiometer on the Veri-Phone to the
full counter-clockwise position. Set gain potentiometer as per the Veri-Speaker wiring scenarios (a) or (b) below:
(a) Under normal conditions with the Veri-Speaker yellow microphone wire connected to a single microphone
channel (terminals 6 or 7 or 8), the initial position for the Veri-Speaker microphone gain potentiometer
should be at the full clockwise position.
(b) In the example shown on the following page (with the yellow microphone wire connected to all three termi-
nals 6, 7 and 8), the initial setting for the Veri-Speaker microphone gain potentiometer should be set to the
"one-half" position (see comment 2 below).
2. When using only one microphone, it is advisable to connect microphone inputs 1,2, and 3 together. When doing
so, avoid VOX feedback by reducing the Veri-Speaker microphone gain potentiometer to the "one-half" position.
3. Set the speaker volume potentiometer on the Veri-Phone module to the full clockwise position.
