Specifications

Operation Details (Continued)
Software Diagnostics. 5120 systems are equipped
with a built-in software diagnostic program that, upon
power up, determines if any troubles are present in the
system and informs the user. Should a trouble condition
occur during normal operation, LEDs on the CPU or
communication boards with the trouble condition advise
the operator.
Battery Backup. Since the 5120 operates on the
5120-9174, 6 A, 24VDC power supply, the system can
remain operable when commercial power fails by using
an optional uninterruptible power supply (UPS) consisting
of a 5120-9175 with 5120-9172 battery set. When this
option is ordered, (1) UPS is required per system power
supply. (Refer to data sheet S5120-0055 for additional
information.)
Built-In RS-232 and 10 BaseT LAN Ports. Each
5120 is equipped with EIA RS-232 and 10 BaseT LAN
ports that can be utilized for many functions. Both ports
allow full field programmability through a Windows
based programmer.
Optional Equipment
5130-9165 Master Clock. The 5130-9165 Master
Clock Assembly can be directly integrated into the system
for correcting clocks and automatically controlling the
eight (8) internal relays. Cycling of any one, or all relays
during user programmable time periods is available. This
option also provides a printer port for Station Message
Detail Recording (SMDR). By connecting a printer to this
port, a hard copy log of system call activity can be
generated showing the time, day, date and length of each
station’s calls
5120-9150 Graphic Board. The 5120-9150 Graphic
PC Board provides 72 open collector outputs for driving
custom graphic call annunciation panels. Each output can
drive up to 28 mA @ 24 VDC.
5120-9151 Graphic I/O Board. The 5120-9151
Graphic I/O PC Board provides 72 outputs for driving
custom graphic call annunciation panels. Each output can
drive a single LED. Each output may also monitor a
switch input for direct selection of intercom stations,
emergency tone activation, and time schedule control.
5130-9132 Paging Board. The 5130-9132 Paging
Board is used to provide 24 individual one-way page
ports. These outputs are intended to drive multiple
speaker zones using self-amplified speakers or to drive
25/70-volt amplifiers. These 1 VRMS outputs are
specifically designed to drive these devices directly
without the need of any type of impedance matching
modules. A dry contact closure is also provided for each
output for overriding, or interconnection with auxiliary
equipment.
Systems Integration
The 5120 is easily integrated with premise Key and PBX
telephone systems. When integrated with select PBX
systems, the following features are available:
Caller ID trunk integration*
Access to intercom and paging functions through
PBX phones
Universal night ring
Override paging
Emergency tone activation
Clock synchronization
* Caller ID information can be passed from the 5120 intercom
system through most PBX phone systems via their Caller ID
trunk ports and to an administrative phone equipped with a
display. This is especially useful during emergency call-in
situations, as the exact caller location will be displayed.
