Specifications

Bogen’s UTI312 is a multi-zone paging controller with universal telephone interface.
It is expandable from 3 to 12 zones in 3 zone increments using ZX3 expansion modules.
Each zone has its own buffered paging output (150 speaker drive capacity) with volume
control, a C-form relay contact and “zone active” indicator. Each module includes a
pluggable 24V DC power distribution terminal strip and pluggable terminal strips for
each zone for easy wiring. A built-in 24V DC, 1A power supply is provided for powering
amplified speakers. The UTI312’s universal telephone interface is identical to the UTI1.
Two background music (BGM) inputs, with volume controls, provides each zone with a
choice of BGM sources or no BGM. Two tone triggers are available as well as a 90V
night ringer input. Separate volume controls for the night ring and tone triggers,
along with an adjustable page level limiter, make it easy to set appropriate levels.
Powerful software features provide the UTI312 enormous flexibility for demanding
applications. Two, 3, 4, or 5 digit dialing plans allow the UTI312 to fit into any dialing
structure. Twenty-four zone groups, zone groups for each tone input and night ring as
well as a zone group for the override input provide plenty of installer flexibility. A pro-
grammable AUX relay contact, in addition to the zone relay contact, provides flexibility
for controlling external equipment based on the UTI312’s activity.

Override Zone Group
The override input on the UTI312
has the highest priority of all the
inputs but does not have to provide
an all-call function. Since the over-
ride has a zone group associated
with it, the installer can determine
which zones receive pages during
an override.
For example, assume that in a 12
zone system 11 zones are used to
provide audio to different parts of a
building, but one zone is not used for
audio purposes. The contact closure
for this zone is used to control a
door latch. When this zone is active,
the latch is open. If the override was
predefined to activate all zones, then
the door latch would open during
override operation which may not
be desirable. By programming the
override zone group with all zones
except the one connected to the
door latch, an override can be made
and still leave the door locked.
Two Background Music Inputs
In a system with multiple zones,
it is not uncommon to find applica-
tions that have different background
music (BGM) requirements in
different zones. To provide flexibility
in these situations, the UTI312 has
2 BGM inputs. Each zone, through
jumper assignments on the ZX3
module, can select one or the other
BGM source, or none at all.
Auto Select Paging
When using the auto select paging
feature, there is no need to dial a
zone or zone group. Whenever the
paging input becomes active, the auto
select paging zone group, with user-
assigned zones, will determine what
zones are active. This may seem to
be an unusual function for a multi-
zone paging application. However,
often the need for zoning is deter-
mined not by voice paging needs,
but by the need to play tones in
different zones.
In these instances, a shift change
tone may need to be produced in
the factory areas but not in the office
areas. So a tone trigger zone group
will be set up to channel the tone
just into the factory. In this case,
voice paging is done like an all-call,
but the tones are zoned.
