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 override 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 pur-
poses. 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 the
door will remain locked.
Two Background Music Inputs
In a system with multiple zones, it is not
uncommon to find applications 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 fea-
ture, 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
determined not by voice paging needs,
but by the need to play tones in differ-
ent 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.
ZX3
3-Zone Plug-In
Expansion Module
(one included
with UTI312)
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
(page 31). Two background music (BGM) inputs, with volume controls, provide 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 appli-
cations. 2-, 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 programmable
AUX relay contact, in addition to the zone relay contact, provides flexibility for controlling
external equipment based on the UTI312’s activity.
