INSTRUCTIONS.
Description.
The TR-8 module has 5 inputs indicated as ABCDE and controlled by
binary signal from 3 up to 24 V dc. Thanks to the correspondent binary
combination, the 32 resulting messages can be recorded or played,
during a maximum time of 3,2 sec for each one. All inputs can be
inhibited thanks to an independent input.
The module also includes 4 supplementary inputs, numerated from 1
up to 4, which can be directly activated by a 24 Vdc positive signal and
with a priority play regarding any other previous selection or a selection
at the same time. The maximum capacity accepted by these
supplementary inputs is 4,4 sec.
The device incorporates a volume control, a push button as well as a
microphone for recording.
Installation.
The module's installation has to be preferably done into an enclosure or
a rack, correctly ventilated, avoiding any contact between the circuit
and metal objects.
Do not install the device in humid places, under high temperatures, or in
contact with liquids.
Do not supply the module before to finish its installation. Please
carefully read this instruction manual.
Control Signals. Composed by 11 connection inputs (5 x BCD, 4
priority, 1 inhibition and the negative), they are electrically insulated
from the rest of the circuit. For this reason, it is necessary to connect
the negative of the signal with the signal which had to excite inputs and
the common negative of control inputs.
It is recommended to minimize at the maximum, the cable length for
theses inputs, using if possible shielded cable.
Loudspeaker Output. The maximum power supplied by the module is
5 W. It is better to use a loudspeaker with a minimum of 10W. with an
impedance from 4 up to 8 Ohms. For this output, you can use a
standard shielded cable.
Suggestion. The device has 4 holes of 3.5 mm to be fixed. More over,
thanks to Cebek C-7587 guides, it can be install in a DIN-RAIL.

TECHNICAL CHARACTERISTICS.
Sintesis BCD Controller.
Power Supply.
The module's feed, independently of the feed used for control inputs,
has to be done through a 24 VDC voltage perfectly stabilized; for that,
we strongly recommend you to use a short-circuit power supply with a
low ripple level. Do never use standard a power supply, neither
rectifiers, who can damage the module operating mode.
Note: To be in accordance with the EEC regulations, a switch and a
200 mA fuse have to be installed on the positive of the feed input.
Both are necessary for the module's protection.
Recording.
To configure the device in recording mode, you have to put in ON
position the switch Nº3 of the battery for the functions control, and the
REC Led will light.
Then, you have to select the number of the message in which you
want to make the recording. See paragraph "To activate control
signals". Pressing the push button "push", and during its pressure, the
module will record through the microphone. If you stop to press the
push button, or if you exceed the maximum allowed time by the
message, the recording will automatically stop.
During the recording process, the RUN Led will intermittently light
from the beginning to the end.
AGC. The module has an Automatic Gain Control (AGC), which
allows to stabilize the signal level received by the microphone. To
activate the AGC function, the ON jumper has to be closed or joined.
At the opposite, to deactivate this function, the OFF jumper has to be
closed or joined.
Attention: Both jumpers can never be closed at the same time.
The device is supplied with the AGC function activated, mode that we
suggest to maintain.
Specifications to record. Before to start to record, it is better to
reduce at the maximum the volume control, to be close to the
microphone and to clearly speak.
