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.
