BASE MODULE J3 WIRING
All Base Module audio inputs are balanced and there are two ways to
use them:
audio verification sensor inputs
audio from optional SmartAudio or ListenIn Modules
NOTE: When installing SmartAudio or ListenIn Modules in the
Advantage plus system we strongly recommend that you
not connect AudioSensors to the Base Module audio
inputs.
Audio from SmartAudio and ListenIn Modules is a balanced signal,
requiring
two wires for each audio input and output. If you install
either of the modules you must connect the Base Module AU+ and
AU- inputs to the corresponding outputs from the modules.
Audio Input Wiring
IMPORTANT!
YOU MUST USE SEPARATE TWISTED PAIR,
INDIVIDUALLY SHIELDED CABLES FOR THE
AUDIO AND RS-485 DATA BUSSES. RUNNING DATA
AND AUDIO IN THE SAME CABLE CAN RESULT IN
SERIOUS DATA NOISE IN THE AUDIO SIGNAL.
If not installing SmartAudio Modules or ListenIn modules, you can
connect up to four verification AudioSensors to Base Module jack J3.
Audio verification devices should only be Advantage AudioSensors.
NOTE: Advantage plus is NOT compatible with the older
Advantor PA-15 and GBD-III audio sensors.
General Advantage AudioSensor placement rules are:
1. Mount AudioSensors on solid,
non-vibrating surfaces.
2. The AudioSensor should always face toward the protected area
and away from ambient noise sources.
3. Mount the AudioSensor as close as possible to the area being
protected.
4. Mount AudioSensors high enough to avoid blockage, damage
and tampering, but give more thought to sound factors. The ideal
mounting height is 8 to 10 feet from the floor. Never exceed 13
feet unless special circumstances require such height.
5. Mount AudioSensors at least one foot away from corners.
Power, ground, and audio wiring is identical for all system audio
sensors. We recommend using an audio color code of Black
(ground), Green (audio), and Red (+12VDC). Figure 4 and the
installation diagram shows examples of proper wiring using the
standard (BLK, GRN, RED) color code.
NOTE: For best audio quality, the +AS and -AS terminals on
Base Module jack J3 should be the
only source for
AudioSensor power and ground.

Figure 4. Advantage plus Jack J3 Wiring
To save wire you may parallel power (Red) and ground (Black) to
several audio sensors.
Always home run and connect each audio
(Green) wire to the Base Module audio sensor input number desig-
nated on the Option Summary Sheet. For best audio quality, install
one AudioSensor at each audio input.
Do not connect a ground wire to a +AS terminal, which is +12VDC.
DAT1 & DAT2 (J4 Pins 1 through 4)
Base Module J4 pins 1 through 4 are the RS-485 communication port
connections. The RS-485 communications port gives Advantage
plus its flexibility and expandability.
The Base Module’s RS-485 communication port can interface and
control the following optional modules and devices:
any combination of up to 16 LCD plus and LED plus
keypads
eight alarm loop Expansion Modules
any combination of up to eight SmartAudio Modules and
ListenIn Modules
seven Access Modules
Use the following guidelines when running cables for an RS-485
communication link:
Never exceed 2,000 feet from the Base Module
Always use 22 AWG, individually twisted pair, individually
shielded cable. (See Note below)
Always observe the proper polarity when making connections
(e.g., DAT+ to DAT+ and DAT- to DAT-).
Always verify the proper RS-485 address jumper settings on
each module or device.
Always use the cable’s drain wire, one of the cable’s spare
wires, or a shield to bond the signal grounds (
NOT earth
grounds) of the interfacing modules.
NOTE: RS-485 cable runs of less than 30 feet should not require
twisted pair, individually shielded cable.
Although RS-485 uses a two-wire differential communication, it is
imperative that the signal grounds of the interfacing modules be
bonded together. This common signal ground provides an overall
reference level, eliminating most RS-485 communications problems.
When running RS-485 cables to several modules or devices you can
use both daisy chain and star configurations (see Figure 5).
UL WARNING:
LCD/LCD plus KEYPADS WITH A BLINKING YELLOW
LED, A BLINKING CURSOR AND BEEPING EVERY 10
SECONDS, INDICATE AN RS-485 COMMUNICATIONS
PROBLEM. THE SYSTEM MAY BE INCAPABLE OF
REPORTING FIRE OR BURGLARY ALARMS.
UL requires that at least one LCD/LCD plus keypad be powered
directly from the Base Module to permit display if other modules lose
power.
