Introduction
The Model 12576-315 Access Panel is a component of the SmartSeries®system that may be used for
public address, intercommunication, and emergency notification.
How to Use the Assembly
Application
The Model 12576-315 Access Panel is a desktop-mounted assembly with a 120 V ac/240 V ac power
input. This power input allows the access panel to be used in almost all installations without requiring
additional line transformers. The access panel can be used to initiate alarms and to monitor system
activity via a vacuum fluorescent display (VFD). A piezo audible alarm is included which is typically
used to alert personnel of updated system status.
The access panel provides 17 configurable push buttons. Each push button contains an LED lamp that
can be configured to provide system status information. The panel provides a handset equipped with an
integral pressbar. The handset is used to make page announcements and to hold two-way party line
conversations. In addition, an internal speaker is provided to allow page audio monitoring. The access
panel also includes a dedicated speaker mute push button with LED lamp. The LED operation and
function of this push button are pre-defined by the access panel and can not be changed.
The Model 12576-315 Access Panel consists of the following main components:
•Vacuum fluorescent display
•17 configurable push buttons
•Speaker mute push button
•Handset
•Speaker
•Piezo alarm
The function of each of the other 17 push buttons is software configurable. Contact GAI-Tronics for
more information on configuration of the access panel.

Interfaces
A three-conductor ac power cord is included with the access panel. One end of the power cord is
connected to the three-prong connector located on the back of the access panel, while the other end is
plugged into a grounded ac electrical outlet. The compatible ac input voltages are 120 V ac/240 V ac
(auto-ranging), 50/60 Hz.
Data and audio connection to the system control unit is provided by a four-position terminal block located
at the rear of the panel. The physical connection is a single twisted-pair cable connection using two of the
four terminal points. One of the remaining two points is tied to chassis ground and may be used to
connect to a cable shield if shielded cable is preferred.
Note: Ensure that only one end of the cable’s shield is grounded in order to avoid ground loops. The
remaining terminal point is not used.

Installation
WARNING Please adhere to all warnings, safety, and operating instructions on the unit
and in the installation manual.
1. Disconnect power before servicing.
2. Avoid servicing the unit during electrical storms.
3. Do not touch uninsulated wires.
Mounting
Remove the access panel from its protective packing. Simply position the access panel on a sturdy
horizontal surface in a convenient location where the handset and push buttons are readily accessible.
Data Connection
Connect a twisted-pair cable from the access panel terminal block points labeled VOICE/DATA COM. to
the corresponding connector on the appropriate termination block of the control unit. This connection is
not polarity-sensitive and may be wired in either orientation. A chassis ground (labeled E-GND) is also
provided on this terminal block to connect to a cable shield if shielded cable is used.
Notes: 1. The data cable is not included with this assembly and must be purchased separately.
2. If shielded cable is used, only one end of the cable’s shield should be grounded in order to
avoid ground loops.
Power
Connect the three-conductor ac power cord provided with the access panel as follows:
1. Loosen the captive screw on the connector lock of the three-prong power connector at the rear of the
access panel.
2. Plug one end of the power cord into the three-prong power connector at the rear of the access panel.
3. Tighten the captive screw in order to clamp the connector lock around the power cord. Plug the other
end into a grounded ac electrical outlet.
4. The access panel does not contain an internal power switch. The access panel will power up
immediately.
Push-Button Overlay
To install or replace the push button overlay, proceed as follows:
1. Loosen the eight mounting screws located along the edge of the existing push-button overlay using a
1/16-inch Allen wrench or equivalent. Save these mounting screws.
2. Lift the existing push-button overlay away from the access panel.
3. Mount the new push-button overlay onto the access panel, aligning the screw holes on the overlay
with those on the access panel.
4. Replace and tighten the eight mounting screws using a 1/16-inch Allen wrench or equivalent.

Operation
Operation of this assembly is highly dependent on the attached system’s software configuration. The
software is factory-created and subsequently downloaded to the system control unit via an external PC at
system start-up.
This access panel offers the standard features described below in addition to other configurable features.
The standard features include a handset used for page and party functions, an internal speaker to monitor
page audio, an illuminated speaker mute push button used to mute the internal speaker and indicate the
current state of speaker muting, a vacuum fluorescent display (VFD) to provide system status in a text
format, and a piezo alarm that can be activated to alert a user of a change in system status.
Handset Communications
The handset is used for both page and party communications. Lifting the handset from the cradle creates
an off-hook condition. In a normal configuration, lifting the handset causes it to be connected to a party
line.
Speaker and Speaker Muting
The access panel’s internal speaker provides the capability of monitoring system page activity. The
speaker may be muted to block the page line broadcasts through the use of the speaker mute push button
located to the left of the speaker. When pressed, the push button illuminates indicating that the speaker is
muted. The speaker remains muted until the speaker mute push button is pressed and released a second
time. Then, the speaker resumes normal operation and the speaker mute push button extinguishes.
Vacuum Fluorescent Display (VFD) and Control
The VFD displays status messages from the system control unit in a text format. Typically, the push
buttons to the right of the VFD are configured for NEXT and PREVIOUS functions. Use the NEXT
push button to view each additional new message. The NEXT push button can be configured to flash
when a new message is available. Use the PREVIOUS to cycle backward in order to review old status
messages.
Piezo Alarm
The piezo alarm is an audible indicator. It is typically configured to sound when a new message is
available on the VFD. If configured as described above, press the NEXT push button to display each new
message. When the last available new message has been displayed, the piezo alarm turns off. The exact
details of the operation of the piezo alarm are configurable.
