General Information

The Model 12576-115 Access Panel is a component of the SmartSeries system that may be used for
public address, intercommunication, and emergency notification.

How to Us e the Assembly

Application

The Model 12576-115 Access Panel is a standard EIA 19-incsh 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 that 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 12576-115 Access Panel are as follows:

• Vacuum fluorescent display

• 17 push buttons

• Handset

• Piezo alarm

The function of each of the 1 7 pus h buttons is software configu rable. Conta c t GAI-Tr onics 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 c onnec tion to the system co ntrol unit is provide d by a fou r-position terminal bl ock lo c ated
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.

OTE: Ensur e t hat onl y 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

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 the access panel with the appropriate screws. When installed correctly, the handset
will be on the left side of the access panel.

Data Connec tion

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 p olarity-sensiti v e and may be wired in eit her or ientat ion. A chassis ground (lab el e d E-GND) is also
provided on this terminal block to connect to a cable shield if shielded cable is used.

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 Ov erlay

To install or replace the push butto n overlay, pr oceed as foll o ws :

1. Loosen the eight mounting screws located along the edge of the existing push button overlay using a

1/1 6-inch Allen wrench or equiva lent. Save these mou nti ng s crews .

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. Rep lace and ti ghte n the e ight mountin g scre ws using a 1/16-inch Allen wrench or equiva lent.

Operation

Operation of the access panel is highly dependent on the attached system’s software configuration. The
software is factory-created and is subsequently 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 options including a
handset for p age and p arty functions, a vacuum fluores cent display (VFD) that s hows th e system st atu s in
a text format, and a piezo alarm that may be activated to alert the operator 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.

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 pus h button c an b e conf igur e d to flash
when a n e w mes s age is availa b le. Use t h e 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
ava ilabl e on the VFD. I f configur e d as described above, press the NEXT push button t o display each n e w
message. When the last available new message has been displayed, the piezo alarm turns off. The exact
deta ils of the operation of th e p iezo alarm ar e c onfi gurab le.
