Introduction
The Model 12576-125 Access Panel is a component of the SmartSeries system that can be used for public
address, intercommunication, and emergency notification.
How to Use the Assembly
Application
The Model 12576-125 Access Panel is a standard EIA 19-inch rack-mount 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 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.
The main components of the Model 12576-125 Access Panel are as follows:
• Vacuum fluorescent display
• 27 push buttons
• Handset
• Piezo alarm
The function of each of the 27 push buttons is software configurable. Contact GAI-Tronics for more
information on configuration of the access panel.
Of the 27 push buttons, 23 contain an LED lamp that can be configured to provide system status
information. The four remaining push buttons, including the lower push button to the right of the VFD
and the lower three push buttons in the rightmost column of five switches, contain non-functional LEDs.
These non-functional LEDs may be used as spares.

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 compati ble ac inpu t vo ltag es 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 pre ferred.
OTE: Ensure that only one end of the cable’s shield is grounded in order to avoid ground loops. The
N
remaining terminal point is not used.
A second four-position terminal block is provided for optional connections:
• Two terminals are available to connect a single 40-ohm (nominal) external speaker for page audio
monitoring.
• Two terminals are available to drive an external piezo alarm.
Contact GAI-Tronics Service Department for further information.
OTE: The piezo alarm is a polarity-sensitive device. Ensure that proper polarity is observed when
N
connecting it to the access panel.

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
NOTE: Mounting hardware is not included with this assembly and must be purchased separately.
Remove the access panel from its protective packing. Position the access panel in the 19-inch EIA
enclosure and secure it with the appropriate screws. When installed correctly, the handset will be on the
left side of the access panel.
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.
OTES:

Power
Connect the three-conductor ac power cord prov ide d with the access pane l as follo ws:
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 sub sequ ently downloaded to the system control unit via an external PC at
system start-up.
This access panel offers the following standard features in addition to the configurable features. The
standard features include a handset used for page and party functions, a vacuum fluorescent display
(VFD) used 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.
Va cuum 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 NE XT 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.
