Operation
Individual Channel Volume/Mute
— The volume on each channel
may be set independently, allowing the operator to prioritize
listening based on volume. The LCD display shows volume
percentage, allowing accurate settings. Single button muting
instantly reduces the volume of a channel to a predetermined
level.
Call
— When channel activity is present, the channel’s “CALL”
indicator blinks, making it easy to locate the source of the call.
The call indication remains for a few seconds after the call stops
in the event the operator is busy with another activity.
Patch
— The simplex, VOX operated patch can patch together
channels-to-channels or channels-to-telephone lines. The
operator may monitor the patch and operate on other channels.
Transmit
— The operator may transmit over the selected
channel(s) by pressing the “Transmit” button or by pressing the
optional foot-operated transmit switch. With “Instant Transmit”,
the operator may transmit over a non-selected channel to reply
to a call without changing channel selection.
Monitor
— This allows the operator to disable coded squelch on
the selected channel so the channel may be monitored for traffic
prior to transmitting.
Alert
— Up to four different alert tones may be transmitted to
indicate the type or priority of the dispatch to follow.
Auxiliary Input/Output
— Operators may control various contact-
closure operated devices (such as lights, door locks, and voter
controls) from the console. External inputs (such as voter
displays and alarms) may be monitored at the console.
Instant Call Paging
— The operator may “tone out” an entire
sequence of pages with the press of a single Instant Call
button. Paging sequences are automatically routed to the
proper channel and frequency, eliminating potential human
errors. Paging sequences may contain self-initiating alert tones
for indicating specific types of events. The button’s indicators
provide a “check list” to verify that the proper pages were sent.
Multiformat capability eliminates the need to have a different
encoder for each type of pager/decoder.
Programming
One of the unique
features of the
Model 4010 system
is that it is FULLY
field programmable
with the Console
Programming
System (CPS) and
an IBM-compatible
personal computer.
CPS not only allows channels to be configured for various
types of base stations, but it also allows any button to be
assigned any available function. This eliminates costly upgrades
while allowing the buttons to be reconfigured at any time
to accommodate new operating procedures or radio system
changes. Key top labels are removable and do not require
engraving, allowing the keys to be relabeled as easily as they
are programmed. Standard key top legends are supplied by
Zetron while custom legends may be created in the field using
transparent key tops.
The console is shipped from the factory programmed and
labeled to customer specifications, with a CD containing
the Windows Console Programming System and the factory
programming files.
Changing the function of a key is simply a matter of using
the cursor to select a new function from a menu-style list on
the computer screen. When all selections are made, the new
configuration is saved on the diskette and printed out for a paper
copy. When ready, the stored configuration may be downloaded
to the console in a matter of seconds. Configurations can also be
uploaded from a console to a PC for storage or modification.
Installation and Maintenance
The Model 4010 is fully self-contained
requiring no external electronics.
It uses industry standard 25-pair
cables and punchdown blocks for
interfacing to radios and leased
lines. Standard or lightning-
protected connectorized punch-
down blocks are available.
External options, such as desk-
mic and headset jack are also
connectorized. All line adjustments,
status LEDs and configuration switch es are accessible through
the rear panel without any disassembly.
The Console operates from 12 Volts DC, which is available from
Zetron’s uni versal power-supply that accepts any voltage from 95
to 250 VAC at 47 to 440 Hz. The universal power-supply has UL,
CSA and VDE approvals.
The “clam-shell” design of the desktop Model 4010 and
the easily-removed back and top of the rackmount model
make access for maintenance and upgrades easy. All channel
electronics are contained on plug-in circuit cards for easy
replacement or expansion. Audio throughout the console
remains analog and is not digitized. In addition to providing
superior audio fidelity, this makes audio troubleshooting easier.
The service manual contains full schematics, parts IDs, parts lists
and theory of operation. Factory service, spare boards, and spare
parts kits are avail able.
