General Information
Product Overview
The S.M.A.R.T. Modules are a collection of function-specific modules that perform various fault
detection chores in extended range communication systems. It is an alarm and an alarm supervision
system that is transparently incorporated within a public address/paging system, such as the Nova 2001
Public Address System. The modules are designed with a common serial interface to a GAI-Tronics
central processing unit. The CPU forwards the system indications to an operator paging console typically
located in a control room or office.
The S.M.A.R.T Modules are capable of monitoring many components of any type of wired audio paging
system for health status and report faults both locally through logic closure outputs, and remotely via
serial data link.
•
The low-level audio paths through a system are monitored by the use of sub-audible tones mixed into
inputs and detected on outputs.
•
The high-level power audio connections are monitored for integrity by measuring loop resistance and
ground fault leakage.
•
Individual loudspeaker integrity can be checked using the remote speaker modules that sample
speaker audio current. When commanded, these modules report their health-status to a central
location via RF data modem over the audio distribution lines of a central-amplifier system.
•
The remote speaker modules are also capable of changing individual loudspeaker power levels on
command from a central location. This can be done on a system-wide or individual-speaker basis.
The range of adjustment is in steps from off-mute to full power.
System Requirements and Limitations
The Nova 2001 S.M.A.R.T. Modules are either housed in a central cabinet or installed in field locations,
and each typically requires an uninterruptible 24 V dc power source.
A complete system can support up to 120 zones, each containing as many speakers as the power amplifier
can support.

Description of the Nova 2001 S.M.A.R.T Components
The Nova 2001 System can combine some or all of the modules described below with a common serial
interface to the GAI-Tronics Nova 2001 Central Processor Unit. The Line Integrity Module (LIM) and
the Automatic Level Control (ALC) master modules are able to perform on a stand-alone basis and
interface alarm statuses via solid-state relay closure outputs.
The following is a list of the S.M.A.R.T. modules. Some or all the modules may be purchased depending
on specific customer requirements.
•
Line Integrity Module (12389-001) consists of the LIM Speaker Line Termination Board
(69389-010) and LIM Controller Board (69389-020) connected by a ribbon cable. It monitors the
line resistance as a means of detecting and reporting line faults. The module injects a selectable (10,
20, 30, 40, or 60 mA) current on each speaker line. During initial set-up, a baseline resistance is
established and the LIM report changes of more than 20%, which would indicate an open, short, or
leakage to ground has occurred. The LIM can also be used in other systems where line resistance
may be measured as a means of health-check.
•
Test Tone Generator Module (12393-001) provides low frequency test tones used to health-check
the low-level audio paths and power amplifiers. This module is used in conjunction with the Test
Tone Monitor and the Speaker Master Control Module as a power source for remote speaker
modules.
•
Test Tone Monitor Module (12399-001) detects the low frequency tone that is injected into the low
level audio pathways for use in health-checking cabinet wiring.
•
ALC Master and Remote Modules (12395-001) sample and analyze the ambient noise within a
paging zone and adjusts low level audio to the associated power amplifier.
•
Speaker Master Control Module (12403-001) controls power to the remote and transmits the power
level tap commands to the speaker remote modules and receives the speaker coil health check status
from the Speaker Remote Modules.
•
Speaker Control Remote Module (12402-001) receives power level tap commands to control
speaker volume and health checks the speaker coil.
Each module, and its function, set-up, and adjustment is described in detail in this manual. Refer to the
block diagram on page 3.
The Model 12604-014 Replacement Fuse Kit is available for all of the S.M.A.R.T. Modules. It contains
10 of each of the required sizes.

Locating S.M.A.R.T Modules in the Central Cabinet
The S.M.A.R.T. modules must be housed in a cabinet or enclosure located in an environmentallycontrolled area. In larger installations, an auxiliary panel devoted to some of the modules is desirable.
The optimum configuration is to have the installed modules horizontally in “snap-track” style mountings
that directly face the technician. When mounted in this manner, all board-mounted controls and
connectors are easily accessible.
Central Processor Unit
The Nova 2001 Central Processor Unit controls larger, more complex systems, and is usually housed in
the central cabinet along with other system equipment.
The CPU polls the various S.M.A.R.T modules via a common RS485 serial bus and sends commands, as
needed, to monitor the system health and supervise the ALC modules. The system CPU is responsible for
setting up both manual and automatically-initiated voice paging and the monitoring of various alarm
inputs.

Line Integrity Module (LIM)
Description
The LIM Module (GTC 12389-001) consists of two PCBAs, the LIM Speaker Line Termination Board
(GTC 69389-01x) and the LIM Controller Board (GTC 69389-02x), connected by a ribbon cable. The
LIM can monitor the speaker wire line integrity by measuring the resistance of up to 8 zones or speaker
loops and reports faults on the line. When attached to a remote loudspeaker or ac power line, the LIM
breaks the dc loop continuity and isolates the gap with a large capacitance. The LIM monitors the dc
continuity of the loop by applying a selectable calibrated dc current across the isolating capacitors and
monitoring the dc portion of the loop for changes of more than 20% in loop resistance.
Furthermore, a test for leakage to earth is conducted by applying a dc voltage between the line loop and
earth ground and monitoring the current drain on the applied potential to determine acceptable limits of
leakage to earth. The application of excitation current and the measurement of the result is under the
control of a microcontroller and is multiplexed over 8 lines per module.
In a complex alarm management system, the LIM communicates the alarm status with the system CPU
via RS485. Under RS485 (advanced) control the test interval is under the supervision of a system central
processor unit. This control can include modification and subsequent overwrite of an individual line
mean value in the form of positive or negative “tweaks.”
The LIM is also able to stand alone in a simple system and output alarm status on 8 line-unique, opticallyisolated alarm closures. The supervised or stand-alone mode selection is via the address jumper field,
JU2 through JU5 on the LIM controller PCBA.
Controls
The LIM module contains two push buttons, ANALYZE/STORE and TEST/STEP, and a rotary lineselect switch. The button functions for the normal mode are ANALYZE and TEST, and are STORE and
STEP in the program mode.
In the normal mode, pressing the ANALYZE button causes any fault condition on the line currently
selected by the rotary switch to be displayed on the fault-descriptive LEDs:
•
Line SHORT
•
Line OPEN
•
LEAK

NOVA 2001 PUBLIC ADDRESS SYSTEMS - S.M.A.R.T. MODULES
Set-Up
Install the LIM modules in the central cabinet using the standard “snap-track” style mounting. Ensure the
push button controls and the LED indicators are easily accessible to the operator or technician for
diagnostic tools. Refer to the system block diagram on page 3.
WARNING
Never separate or rejoin the PCBAs at J2 and J3 with the ribbon cable while
the power is applied!
1. Install the ribbon connector between J2 on the speaker line termination board and J3 on the LIM
controller PCBA.
2. Connect the audio power lines from the amplifiers and speakers to the appropriate terminal blocks on
the speaker line termination board.
3. Make the 24 V dc power connections to TB20 on the LIM controller PCBA.
4. Install jumper JU1 on the LIM controller PCBA and perform the speaker line selection programming.
Refer to the Program Mode section below for instructions. Remove the jumper when the
programming is complete.
5. Set the LIM for either internal or external control. Internal or external control mode is determined by
the setting of the address jumpers JU2, JU3, JU4, and JU5. These are connected in binary fashion
and determine the serial network address of each individual LIM.
Note: These settings cannot be duplicated when external control is used for multiple LIMs.

connectors J4 and J1 on the LIM controller PCBA.
Operation
The LIM has two operational modes: the normal (measurement) mode and the program mode. The
program mode is selected by inserting a shorting jumper, JU1. Removing the jumper returns the LIM to
the normal mode.

Normal Mode
In the normal mode, at a pre-programmed time interval, the microprocessor selects one of the 8 monitored
lines at a time, applying a specific dc current through the line dc loop, and measures the loop voltage. If
the measured voltage falls within predetermined limits (as defined in the program mode), the line loop
resistance is determined to be within tolerance.
If not, an alarm is initiated as a line-unique logic closure. An LED indication is physically linked to the
alarm closure. If the loop voltage is too high, (above tolerance) the line is assumed to be wholly or in
part, “open.” If the loop voltage is too low the line is assumed to be wholly or in part, “shorted.”
In either case, the out-of-tolerance condition is retained in RAM for further processing as described
below. The leakage test is then applied to the line. An out-of-tolerance failure is indicated by a logic
output from a leakage comparator. The fault determination is a hardware function.
A leakage fault also generates an alarm and this condition is also stored in RAM. Fault testing continues
on all lines regardless of previously existing alarm conditions. This is in order to determine a return-tonormal status. A return-to-normal condition causes an existing alarm to be rescinded (removal of alarm
closure). Long-term fault history and trend information is the responsibility of the system CPU and is not
stored within this module.
There are two functions available in the normal mode: a lamp test, and a display of the fault condition
that caused test failure for any of the eight speaker lines.
Lamp Test
Press and hold both the TEST and ANALYZE push buttons for 3 seconds. All 11 LEDs (3 faultdescriptive LEDs and 8 line alarm LEDs) illuminate and remain so as long as the buttons are depressed.
Note: Be aware that the 8-line alarm relay outputs are activated during the LED test.
Fault Condition Display
Use this feature to learn what specific measurement (line open, line shorted, or line leakage) failed for a
given line during testing so that appropriate repair action may be taken.
1. Select a speaker line with the rotary line-select switch.
2. Press and hold the ANALYZE push button.
3. Wait 3 seconds for the fault indication to be displayed on the summary LEDs. All LEDs are off if the
line passed the most recent testing. The fault indication continues to be displayed as long as the
ANALYZE button is pressed.
Program Mode
The program mode is used to add or delete speaker lines, to set a mean voltage value and corresponding
limits to be used for line testing for each installed speaker line, and to set the time interval for free-run
mode line testing.
The two push-button switches, STORE and STEP, and the rotary line select switch are active in the
program mode. While in the program mode, the microprocessor connects the current generator to the line
selected by the rotary switch.

Set up
1. Enter the program mode by inserting a shorting clip across the program mode jumper (JU1).
2. Select Active Speaker or Zone Lines: Select one of the lines on the rotary line-select switch, S1
using a small flat-bladed screwdriver. Positions 0 through 7 refer to lines or channels 1 through 8,
respectively.
3. Press the STEP button momentarily, causing the current generator to step to the next value (in
circular fashion) and to display the current value on one of the following fault-descriptive LED
settings:
• No LED = 0 mA
(The selected speaker line is considered inactive. Set all unconnected lines to 0 to prevent the
reporting of erroneous fault conditions. No tests will be performed on these lines.)
• SHORT LED = 10 mA
• OPEN LED = 20 mA
• LEAK LED = 30 mA
Note: When JU6, a current-doubling jumper is installed, the current values are approximately doubled
to 20 mA, 40 mA, and 60 mA for the 3 active index values.
4. Select a current value that will result in a displayed voltage value near mid-range. A stored value too
high or too low may result in the calculated limits exceeding the design limits.
5. Press the STORE button momentarily to begin the measurement cycle. During this time, the three
fault LEDs flash sequentially, and then count down in binary. The resultant 8-bit voltage value is
displayed in binary format on the 8-line unique-alarm LEDs (and corresponding output closures).
Note: Line 1 Alarm is LSB and line 8 Alarm is MSB.
6. Set Mean Voltage and Line Testing Limits: Press the STORE button continuously for more than 3
seconds to store the selected current value and the measured result in NVRAM for the line that is
currently selected using the rotary switch. The measured result is used as the mean value and faults
are calculated as deviations greater than +\-20% of the stored value. The three fault-descriptive LEDs
will flash 3 times to indicate that the value has been stored.
7. Set Line Test Interval: When all the lines have been programmed, and the results have been stored,
select the interval for the stand-alone self-commanded test. To do this, move the rotary line-select
switch to the time value according to the table below.

Test Tone Generator Module
Description
The Test Tone Generator Module (GTC 12393-001) is a key component of an S.M.A.R.T. Module
system. It provides the tone signal generation and a method to mix the tone signal into the required audio
pathways. It provides a test signal that is injected into the audio pathways and is monitored at various
points throughout the system. This module is alternately used as a generator for an inaudible source of
power to the speaker remote boards, where used.
The tone generator’s output is programmable and adjusted by the microcontroller. There are 64 possible
levels of output with an approximate 0.3936 dB change per resolution of adjustment. These adjustments
are made by using a 6-bit binary switch settings SWA-3 through SWA-8 to manually set the levels of
tones.
It is designed to allow for enabling and disabling each channel’s tones and for controlling each channel’s
by-pass relays. In a Nova 2001 System, the module is controlled via an RS485 serial link. It can
alternately be controlled via a digital input closure control.
Controls
The Test Tone Generator module contains the following controls and indicators:
Power Indicator LED – This LED lights when the module is energized to indicate that the microprocessor
is working.
S1 – This is a rotary switch used to select the unique unit address for the RS485 connection. Address 0 to
E is used to establish the unique address for each of the tone generator modules in the system. Address F
is used to establish the logic control mode where operation of the module is via external logic closure
inputs.
SWA – This switch allows you to select options in some versions of the firmware, and to initially set
manual tone levels.
SWB – This is a configuration switch that is used to enable external logic controls and to enable external
channel outputs in a system that does not use RS485 control.
JU1 through JU4 – This set of jumpers is used to individually enable POT1 through POT4, respectively.
POT1 through POT4 – The individual potentiometers are used to set the individual tone output levels.
Set-Up
Refer to the board layout diagram.
1. Make the low level audio input and output connections for up to four channels at TBCH1, TBCH2,
TBCH3, and TBCH4 as follows:

3. Complete either the logic input mode setup, or the serial control mode setup, both of which are
described below.
Logic Input Mode Setup
4. Set the rotary switch S1 to address F with a small flat-blade screwdriver.
5. Set switch SWA for the desired tone level by selecting a combination of switch settings as shown
below. When the tone generator module is started in or changed via the rotary switch S1 to the logic
control mode, the tone level is varied via the positions of SWA-3 through SWA-8:
SWA-1: option select – (not used in V1.00 firmware release).
SWA-2: option select – (not used in V1.00 firmware release).
SWA-3: manual tone level selection (switch open = logic 1; switch closed = logic 0) Binary LSB
SWA-4: manual tone level selection (switch open = logic 1; switch closed = logic 0)
SWA-5: manual tone level selection (switch open = logic 1; switch closed = logic 0)
SWA-6: manual tone level selection (switch open = logic 1; switch closed = logic 0)
SWA-7: manual tone level selection (switch open = logic 1; switch closed = logic 0)
SWA-8: manual tone level selection (switch open = logic 1; switch closed = logic 0) Binary MSB
Note:. The same tone level as set on SWA is presented to the mixer inputs of all four lines.
6. Select the desired settings for switch SWB:
SWB-1: Mixer input control source selection (open = inputs always on; closed = external control)
Note: SWB-1 should be closed if mixer input external control signals are being applied to TB1.
Conversely SWB-1 should be open if external control signals are not being applied via pull-up
resistors The mixer inputs will be continuously enabled.
SWB-2: Mixer output control source selection (open = outputs always on; closed = external control)
Note: SWB-2 should be closed if mixer output external control signals are being applied to TB1.
Conversely, SWB-2 should be open if external control signals are not being applied via pull-up
resistors and processor I/O port outputs. The mixer outputs will be continuously enabled.
SWB-3: Not used.
SWB-4: Not used.
SWB-5: Line 1 mixer output control enable (closed = control enabled)
SWB-6: Line 2 mixer output control enable (closed = control enabled)
SWB-7: Line 3 mixer output control enable (closed = control enabled)
SWB-8: Line 4 mixer output control enable (closed = control enabled)

Note: SWB-5 through SWB-8 should be closed to allow either the external control signals or the
continuous-on signal selected via SWB-1 to be routed to the 4 line-mixer outputs. These switches
should always be closed except during hardware testing of the board.
7. Apply the external control inputs to TB1 as shown below. All inputs adhere to the same control logic
scheme:
Logic 0 (input grounded to TB1-9) = mixer input/output disabled
Logic 1 (input floating and pulled high via on-board pull-up resistor) = mixer input/output enabled.
Thus, if SWB is set for external control and no external control inputs are connected, all four mixer
inputs and outputs will be enabled due to the on-board pull-up resistors, and the fact that the
processor drives the mixer output lines on port C to a “logic 1” state at all times.

Serial Control Mode Setup
4. Set the rotary switch S1 to serial control address 0 through E with a small flat-blade screwdriver.
Note: The serial control address must be unique to all tone generator modules or serial
communications will not function properly.
5. Set switch SWA for the desired tone level by selecting a combination of switch settings as shown
below. When the tone generator module is started in or changed via the rotary switch S1 to the serial
control mode, the tone level is initially sent to the digital potentiometer U5 as an initial value, but
after that, all tone levels are sent from the CPU.
SWA-1: option select – (not used in V1.00 firmware release).
SWA-2: option select – (not used in V1.00 firmware release).
SWA-3: manual tone level selection (switch open = logic 1; switch closed = logic 0) Binary LSB
SWA-4: manual tone level selection (switch open = logic 1; switch closed = logic 0)
SWA-5: manual tone level selection (switch open = logic 1; switch closed = logic 0)
SWA-6: manual tone level selection (switch open = logic 1; switch closed = logic 0)
SWA-7: manual tone level selection (switch open = logic 1; switch closed = logic 0)
SWA-8: manual tone level selection (switch open = logic 1; switch closed = logic 0) Binary MSB
Note:. The same tone level as set received from the system CPU is presented to the mixer inputs of
all four lines.
6. Ensure that SWB-1 and SWB-2 are OFF (open).

Test Tone Monitor Module
Description
The Test Tone Monitor Module (GTC 12399-001) is the counterpart of the Test Tone Generator Module,
which injects a sub-audible test tone on a selected audio path(s) in order to verify its point-to-point line
integrity. The tone monitor has 16 input channels that can be dedicated to any audio endpoint whether
low-level (0 dB) or high level (100 VRMS).
The tone monitor uses frequency-programmable filters for the detection of the test tone. The 16
monitoring channels are multiplexed down to 8 detection channels. These are further divided into 2
groups of frequency-programmable channel sets (channels 1 through 8 and channels 9 through 16). A
detection on any given monitoring channel results in a relay closure with an integral LED indicator that is
dedicated to that channel. The closure stays active as long as the tone is present within a latency of 1
second.
During normal operation, only one set of 8 inputs are monitored at any instant in time. The processor
selects the opposite set every 300 ms. One set is 1, 2, 5, 6, 9, 10, 13, 14 (A), and the other is 3, 4, 7, 8, 11,
12, 15, 16 (B).
This module also includes an RS485 data connection that allows a system CPU to query the on/off status
of any or all the tone detects.
Set-Up
Install the tone monitoring module(s) in the system cabinet using the standard “snap-trak” style mounting.

ALC Master Control Module
Description
The ALC Master Control Module Kit (GTC 12395-001) which includes one ALC Remote Module,
provides a means to automatically adjust the volume of voice pages and alarm tones in response to
varying levels of ambient noise in a specific area. In a typical system the ALC master is located in-line
between the low-level audio path switching equipment and the regional power amplifier. The master
module provides line power to the ALC remote module, which is connected to a dummy speaker or other
microphone device for sensing ambient noise.
The ALC Remote Module is located within the paging zone. The ambient noise sample is transmitted to
the Master Control Module to be measured and used to modify the level of the audio to the paging
amplifier.
The master module is equipped with control buttons and indicator lights used during initial set-up of the
system paging volume levels. The internal software allows set up of the paging levels without being
affected by the current ambient noise levels. As fail-safe measures, the audio path through the module is
bypassed with a mechanical relay if input power is lost.
If desired, a person using headphones or an external speaker can monitor sounds in a remote location
using the master module’s auxiliary amplifier output.
Installation
The ALC Remote Module must be installed and set up before the master can be programmed and made
operational. The ALC Master Module is physically located in the central cabinet using the standard
“snap-trak” style mounting.
1. Mount the unit in the rear of the cabinet.
2. Connect the sensing line pair from the ALC Remote Module to TB4-1 and TB4-2. TB4-3 is for a
shield, where used.
WARNING
Observe dc polarity.
3. Connect input from audio path switching to TB2-1 and TB2-2. A shield on TB1-3 should only be
connected on the ALC Module.
4. Connect the output line pair to the power amplifier at TB1-1 and TB1-2. A shield on TB2-3 should
only be connected on the ALC Module.
5. Connect the paging logic input (where applicable) to TB3-1 and TB3-2.
6. Connect the emergency logic input to the TB5-1 and TB5-2.
7. Connect RS485 serial bus where applicable. Two connectors, J1 and J2, are provided for a
daisy-chain connection.
8. Connect 24 V dc input power:
TB6-1: Positive
TB6-2: Negative (return)

Setup Procedure
As a prerequisite, matrix (audio steering chassis) output for this channel is set to 0 dBm (full system
output level).
1. Press the INITIALIZE button for 3 seconds. The microcontroller sets the attenuator to –21 dB and autoinitializes the LVL mode. The ACKNOWLEDGE LED flashes for 1 second, and the POWER LED
begins to flash.
2. Station a partner with a two-way radio at the zone to which this device is associated. Initiate paging,
and with guidance from your partner, adjust the volume level of the page to accommodate the current
ambient noise level by pressing the UP or DOWN buttons. (The microcontroller is in the LVL
mode.) The Bar Graph LEDs indicate the paging and noise levels coming back from the Remote
Module.
3. After the paging and adjusting process is finished, press the CALIBRATE button for 3 seconds.
ACKNOWLEDGE LED flashes for one second. This causes the microcontroller to begin a 10-second
measurement cycle of the ambient noise at the remote site. (Microcontroller measures and averages
noise until the 10-second timer counts down, causes the ACKNOWLEDGE LED to flash, saves the
result in RAM, and waits for Save command.) Note: If the ambient noise level changes significantly
during this calibration period, the noise level will no longer match the adjusted paging volume and the
adjusted paging volume and adjustment procedure must be repeated.
4. After 10 seconds, the ACKNOWLEDGE LED begins flashing signifying that it has completed analysis
of the ambient noise. The Bar Graph LEDs indicate the level of noise from the paging zone. This
visual result may be compared with that which was observed during the test paging.
5. Press SAVE to store the paging volume setting along with the companion noise level.
(Microprocessor stores attenuator reference level and the noise reference level in NVRAM). The
ACKNOWLEDGE LED and the POWER LED cease flashing (normal mode).
6. Test the system by introducing more noise into the controlled zone, and listening to additional paging
over the increased noise. If the paging volume level is not sufficient to overcome the increased noise,
refer to System Optimization below.
System Optimization
After the paging attenuator reference level and noise reference level have been stored in memory, they are
used as a starting point whenever a power-down/power-up has occurred. From this point the
microprocessor measures the “new” current noise level, sums it with the stored noise reference and uses
the difference to add to or subtract from the reference paging attenuator value. This result, always in
RAM is the “current attenuator value.” This process continues indefinitely with exception to the actual
paging period, which is detected by the logic closure input or command via RS485.
The relationship between noise level and attenuator setting is linear at normally 1:1 ratio. As ambient
noise increases in 3 dB steps, the paging audio level is raised by an equivalent amount in 3 dB steps.
However, the ratio between the change in the noise level and the change in the paging level can be
modified to a larger ratio by adding additional steps of paging volume for every step of increase in
ambient noise. The ratio then would be 1:1+N where N is the number of additional steps required.

PAGE 19 of 29
Pub.: 42004-674L2D
For example, if N = 1 and noise goes up by 3 dB, the paging volume goes up 6 dB. This ratio is referred
to as the kick-up ratio and the N number as the kick-up value. This feature is most useful when the
predominant ambient noise in the zone is full-spectrum in nature and tends to mask paging audio more
quickly that single-tone (whine or hum) type noise. Examples of full spectrum noise would be the sound
of gravel running down a chute or the hiss of a large volume of air pressure being released.
If the paging level simply needs to be further adjusted (tweaked) without changing the kick-up ratio, then
perform the paging level update procedure described below.
The minimum paging attenuation may also be established in order to maintain a minimum area coverage
even under completely quiet ambient conditions. This is referred to as Page Min. and is expressed in 3
dB SPL steps.
Note: If at any time the system is in any of the programming modes and no button activity has been
detected for 15 minutes, the system automatically returns to the Normal operating mode using the
operating values that were previously in the memory.
Paging Level Update
1. Ensure that the system is in the Normal operating mode: POWER LED ON – steady.
2. Press the LEVEL button for 3 seconds. The ACKNOWLEDGE LED must flash for one second, and the
POWER LED begins to flash on and off. (The µC is in LVL mode.) Press the UP or DOWN buttons
to modify the paging level.
3. Press the LEVEL and SAVE buttons together for 3 seconds to save the new paging level. (The µC
stores only the new attenuator reference level in NVRAM.) The POWER LED ceases flashing
indicating the return to the Normal mode.
4. The Bar Graph LEDs continue to indicate the audio level coming from the Remote Module for
approximately 5 minutes after a level-save operation and then extinguish. If at any time after the
time-out period you wish to view the level indication, press the LEVEL button momentarily (less than
3 seconds). The Bar Graph LEDs again indicates the level for 5 minutes.
Setting the Kick-up Ratio
1. The system must be in the Normal operating mode: POWER LED on – Steady.
2. Press the UP and DOWN buttons together for 3 seconds. The ACKNOWLEDGE LED must flash for one
second and the Bar Graph LEDs 1, 2, 3, 6, and 7 light steadily and the last three (10, 11, 12) indicate
the kick-up value. This is indicated by:
LED 10 for N = 1
LED 11 for N = 2
LED 12 for N = 3
If none of these three are on, the kick-up value is 0 (ratio 1:1). The µC turns LEDs 1, 2, 3, 6 and 7
on; and turns LED 4, 5, 8, 9 off, and puts the kick-up value in LEDs 10 through 12.
3. To change the kick-up value, press the UP or DOWN buttons.
4. To save the new value in memory, press the SAVE button. The Bar Graph LEDs extinguish and the
system returns to the Normal operation mode.

5. To view the level indication of the noise audio coming back from the Remote Module, press the
LEVEL button momentarily (less than3 seconds). The Bar Graph LEDs indicate the level for 5
minutes.
Setting the Page Min.
1. The system must be in the Normal operating mode: POWER LED on – steady.
2. Press the LEVEL and DOWN buttons together for 3 seconds. The ACKNOWLEDGE LED flashes for
one second and the Bar Graph LEDs 1 and 12 flash. The default Page Min. level of –33 dB is
displayed on LED 10 (-21 dB) down to LED 3 (-42 dB).
3. To change the Page Min. level, press the UP or DOWN buttons. To turn off the minimum page level,
press the DOWN button until LEDs 3 through LED10 are all off.
4. To save the new value in memory, press the SAVE button. The Bar Graph LEDs extinguish and the
system returns to the Normal operation mode.

ALC Remote Module
Description
The ALC Remote Module, included in the Master Control ALC Kit (GTC 12395-001), is housed in a
separate enclosure in the logical subzone to be monitored.
The location of the mounting holes on the 4.0 × 4.0-inch board are shown in the diagram below.
Mounting Dimensions for the ALC Remote Module PCBA
The dummy speaker or dynamic mic must be positioned close by to accurately sample the ambient noise
in the area. The remote is line-powered by the master module, so an additional power source is
unnecessary. The wire line to the master must be of sufficient size to prevent significant resistance losses
to the phantom dc power. See the wire-size chart below.
Guideline: Total line resistance including both conductors must not exceed 20 ohms (10 ohm/wire)

Set-Up
Install the enclosure for ALC Remote Module as close to the remote sensing speaker or microphone as
possible. Ensure the conduit entrances are sealed for protection from dust and moisture.
1. Connect the 2 wires from the remote sensing speaker/mic to TB402-1 and TB402-2. TB402-3 is a
shield connection. If a shield is used, it must be connected only to TB402-3 and not to the conduit.
2. Connect the 2 lines from the ALC Master Module.
Observe polarity. These carry the phantom line dc power and must be connected properly.
TB401-1 is dc positive. TB401-2 is negative.
3. Adjust the amplifier gain settings. The remote sensing amplifier provides 10 gain levels for matching
various sensing devices. The gain levels are listed in the table below. There are two high frequency
filter caps that can be switched in to provide noise bandwidth limiting.

In normal operation the Speaker Master Control Module (GTC 69403-001) communicates with the CPU
via an RS485 connection. It transmits output speaker power level tap and page group control commands
via an RF modem to the remote speaker modules in order to control broadcast volume levels and
locations. It receives acknowledgment messages and speaker integrity messages from the remote
modules.
The module has 4 channels, and transmits and receives RF communication at 245 kHz. Each channel is
connected to the speaker line output of an associated paging zone power amplifier. The module also
controls an associated test tone generator module via a dedicated RS485 connection. This tone generator
provides 35 Hz power (through the zone power amp) to the speaker remote modules.
The PB1 and PB2 push buttons are used for unit configuration and test operation. Pressing and holding
either button for approximately 3 seconds causes the unit to return to Normal Operating mode from either
a Configuration or Test mode. LEDs 1 through 5 reflect the unit’s current mode. When only LED 6 is
illuminated, the unit is in its Normal Operating mode. Switch S1 is used to set the Speaker Master
Controller’s unique address. Switches S2 and S3 are used for parameter entry during Configuration and
Test modes.
Also included with the Speaker Master Board Kit (GTC 12403-001) is the Line Filter Board Assembly
(GTC 69416-001). This board is wired between the amplifier output and the Speaker Master Control
Module to isolate the 245 kHz RF from the amplifier output to reduce the loading effects on the RF
carrier due to the low impedance of amplifier outputs.

Speaker Remote Module
Description
A Speaker Remote Module (GTC 69402-001) is installed with each speaker that is to be remotely
adjusted and monitored. The speaker remote module receives speaker tap control commands from the
speaker master control module via an RF Modem.
Refer to the diagram below for overall dimensions and mounting details.
Speaker Remote Module
It is powered by a 35 Hz signal and monitors the current into the associated loudspeaker in order to
perform a health check on the speaker coil. The transmission of acknowledgments and data, as required,
back to the speaker master module is performed only on command from the master.
The speaker remote provides a selection of four available speaker tap settings. The lowest power setting
may be one of two choices selected by the JU1 jumper position. The firmware also provides the
assignment of four page groups out of a possible 255 for systems that utilize subzoning.
