Jumper Selections*
Tone Selection
The TNG1S provides a menu of 8 tones; of which 4 can be selected to be triggered from the
terminal strip. Place up to 4 jumper shunts at the lettered position that corresponds to the
desired tones (use Tone Selection Table above).The tones will be assigned to the trigger terminals
in the order they fall into from A to H where the first tone selected on the way from A to H is
assigned to T1, the next tone selected is assigned to T2, and so on. If more than 4 tones are
selected, only the first 4 (from A to H) are assigned to the terminal strip. If less than 4 tones are
selected, then only the terminals needed to correspond to the number of tones will be opera-
tional.
Priority Level**
This module can respond to 4 different levels of priority. Priority 1is the highest priority. It
mutes modules with lower priorities and is never muted. Priority 2 can be muted by Priority 1
modules and mutes modules set for 3 or 4. Priority 3 is muted by either Priority 1or 2 mod-
ules and mutes Priority 4 modules. Priority 4 modules are muted by all higher priority modules.
If the TNG1S is muted by a higher priority while it is playing a tone, it will abort that tone play-
back. If the trigger is still active when the TNG1S is unmuted, the tone will begin playing from
the beginning. If the trigger is not active, the TNG1S will resume scanning the terminal triggers
for activity.
Bus Assignment
Certain Bogen products that accept input modules contain two mix buses. In these products, the
Bus Assignment jumpers can be arranged so that the tones are fed to either or both buses. On
single bus products, both bus outputs are tied together. In this case assigning the output to either
or both buses provides the same operation. Using the “Both” jumper arrangement is recom-
mended for these systems.
* Markings on circuit board may differ; use diagram above as reference for jumper settings.
** The number of priority levels available is determined by the amplifier the modules are used in.
Module Installation
1. Turn off all power to the unit.
2. Make all necessary jumper selections.
3. Position module in front of any desired module bay opening, making sure that the module
is right-side up.
4. Slide module on to card guide rails. Make sure that both the top and bottom guides are
engaged.
5. Push the module in to the bay until the faceplate contacts the unit’s chassis.
6. Use the two screws included to secure the module to the unit.
WARNING:
Turn off power to unit and make all jumper
selections before installing module in unit.
Connections
Connect a contact closure between any of the “T” labeled terminals and the COM terminal to
trigger a tone playback.An open collector type output can also trigger operation.A ground
from the open collector triggering device must be connected to the COM terminal to com-
plete the conduction path.
Playback modes
One Time
When a trigger is applied and removed before the tone’s playback cycle finishes, the tone will
play only that one time and stop. A momentary trigger must be present for at least 10 ms to
ensure that the TNG1S will recognize it and no other tone can be playing when the trigger
pulse is applied since the module ignores other triggers applied during tone playback.
Continuous
To cause continuous play of a tone, the trigger must be applied for the entire time during
which the tone is to play. Continuous play of a tone is actually a retriggering of the one time
tone cycle again and again.At the end of a tone’s playback cycle, the TNG1S will recheck the
status of this tone’s trigger. If it detects a trigger, it immediately retriggers the tone and causes
it to play again.This process continues until the trigger is removed. Once the trigger is
removed, the tone will finish its current tone cycle and stop. Some of the tones contain short
pauses between tone playbacks to make them sound proper when played as a continuous
train. A very short break in playback will occur during continuous operation of the mechanical
bell and 512 Hz steady tones.
Trigger operation
There is no priority structure assigned to the different trigger inputs.Triggering is on a first-
come, first-serve basis.The internal microprocessor constantly scans the 4 trigger inputs for
activity and responds to the first trigger it detects as active. Once a tone is triggered, it takes
control of the module operation.All other triggers applied during the tone playback cycle will
be ignored. Once a tone has stopped, the microprocessor continues scanning through the trig-
ger inputs until it detects another trigger and begins playback of that tone.
