Speech Processor Module

1111. INTRODUCTION

. INTRODUCTION

. INTRODUCTION. INTRODUCTION

The SP-2 speech processor is an advanced electronic
record/playback module for short voice messages, up to 20
seconds long. It is designed for manual recording and
electronically triggered playback. When the SP-2 is used in
conjunction with alarm control panels and digital communicators,
calls for help due to fire or burglary may be prerecorded, for
automatic transmission by telephone or by radio (or both),
depending on system configuration. The SP-2 may also be used
as an inexpensive, easy-to-install announcer device, triggered by
motion detectors or by any type of momentary switch.
A miniature microphone and an easily accessible RECORD
pushbutton are included in the SP-2 (as in a common answering
machine). Two audio outputs are provided: 600-ohm line
terminals and an 8-ohm loudspeaker output.
When triggered by a short pulse, the SP-2 plays the recorded
message once and then stops. With continuous triggering, the
message is repeated over and over again, until the trigger voltage
is removed from the START input. An audio input header permits
the installer to choose between recording a message with the
internal microphone (INT) and recording a message from an
external audio source (EXT).
Since the SP-2 complements existing alarm and public
addressing systems, it can be installed within the alarm system's
control panel or inside the loudspeaker housing. Operating power

. INSTALLATION. INSTALLATION

The holes at the 4 corners of the SP-2 printed circuit board serve
for mechanical installation. Remember to leave adequate
clearance between the foil side of the PCB and any metal
surface. For electrical connections, refer to the drawings and
proceed as follows:

1. Apply a continuous 12VDC supply to the 12V+ and the GND-
terminals, observing correct polarity.

2. Connect the playback trigger terminal of the communicator or
control panel to any one of the SP-2 start (ST) inputs. This
connection must be made in accordance with the type of
playback trigger provided by the communicator or the control
panel:

• If the playback trigger is positive, apply it to the voice
processor ST+ terminal.

• If the playback trigger is ground potential, apply it to the
speech processor ST- terminal.

• If the playback trigger is obtained by closure of normally
open "floating" relay contacts, connect these contacts
across the two ST pins located near the REC button.
Alternatively, these floating relay contacts may be used

• If you wish to trigger the SP-2 with a normally closed
switch of a PIR motion detector, connect the N.C. switch
contacts across the speech processor's ST+ and 12V(-)
terminals. Then use the jumper provided with the unit to
short the two ST pins permanently together (these pins
are located near the REC button).

3. Connect the SP-2 SIG terminal to the AUDIO INPUT terminal
of the control panel or digital communicator.

4. To check the recorded message, connect an 8-ohm
loudspeaker across the SIG and SP- terminals of the speech
processor.

IMPORTANT NOTICE: Instructions for connecting the SP-2

communicators, control panels and long-range radio
transmitters are provided in the SP-2 Application Notes
(Publication D-6102-9). The application notes also include
useful information on triggering methods with N.C. and N.O.

applications.

Note: Make sure that a jumper is mounted across the two INT
pins of the audio input header. If you intend to record from an
external audio source, remove the INT jumper and connect the
external audio source across the EXT (+) and (-) pins.

1. Complete all connections as explained in Section 3 and
power up the system.

2. Depress and hold down the REC button, while speaking at
normal voice level about 50 cm (20 in) from the microphone.
When through, release the pushbutton. Remember that
message duration is limited to 20 seconds.

Note: It is advisable to make the recording in a quiet
environment. Turn off nearby radio receivers and noisy
machines, and ask people in your immediate vicinity to keep
silent while you record. If the background noise is too high,
speak closer to the microphone.

WARRANTY

WARRANTY

WARRANTYWARRANTY

Visonic Ltd. and/or its subsidiaries and its affiliates ("the Manufacturer") warrants its
products hereinafter referred to as "the Product" or "Products" to be in conformance with
its own plans and specifications and to be free of defects in materials and workmanship
under normal use and service for a period of twelve months from the date of shipment by
the Manufacturer. The Manufacturer's obligations shall be limited within the warranty
period, at its option, to repair or replace the product or any part thereof. The Manufacturer
shall not be responsible for dismantling and/or reinstallation charges. To exercise the
warranty the product must be returned to the Manufacturer freight prepaid and insured.

This warranty does not apply in the following cases: improper installation, misuse,
failure to follow installation and operating instructions, alteration, abuse, accident or
tampering, and repair by anyone other than the Manufacturer.

This warranty is exclusive and expressly in lieu of all other warranties, obligations or
liabilities, whether written, oral, express or implied, including any warranty of
merchantability or fitness for a particular purpose, or otherwise. In no case shall the
Manufacturer be liable to anyone for any consequential or incidental damages for breach
of this warranty or any other warranties whatsoever, as aforesaid.

This warranty shall not be modified, varied or extended, and the Manufacturer does not
authorize any person to act on its behalf in the modification, variation or extension of this
warranty. This warranty shall apply to the Product only. All products, accessories or
attachments of others used in conjunction with the Product, including batteries, shall be
covered solely by their own warranty, if any. The Manufacturer shall not be liable for any
damage or loss whatsoever, whether directly, indirectly, incidentally, consequentially or
otherwise, caused by the malfunction of the Product due to products, accessories, or
attachments of others, including batteries, used in conjunction with the Products.

3. If you exceed the 20 second limit, the last part of the message
will overwrite its first part, making the message incoherent.
Initiate playback (see 4 below) and verify that this has not
occurred. If the message proves too long, rephrase it to
reduce its duration and record again.

4. To initiate playback for testing purposes, momentarily short
the two ST pins on the PCB together. The message will be
played back once. Repetitive playback will result if the pins
are kept shorted together.

5. Having checked the recorded message, you may now
disconnect the loudspeaker from the speech processor, to
prevent the message from being heard at the installation site
each time the unit is triggered into playback.

The Manufacturer does not represent that its Product may not be compromised and/or
circumvented, or that the Product will prevent any death, personal and/or bodily injury
and/or damage to property resulting from burglary, robbery, fire or otherwise, or that the
Product will in all cases provide adequate warning or protection. User understands that a
properly installed and maintained alarm may only reduce the risk of events such as
burglary, robbery, and fire without warning, but it is not insurance or a guarantee that such
will not occur or that there will be no death, personal damage and/or damage to property
as a result.

The Manufacturer shall have no liability for any death, personal and/or bodily injury
and/or damage to property or other loss whether direct, indirect, incidental,
consequential or otherwise, based on a claim that the Product failed to function.

However, if the Manufacturer is held liable, whether directly or indirectly, for any loss or
damage arising under this limited warranty or otherwise, regardless of cause or origin, the
Manufacturer's maximum liability shall not in any case exceed the purchase price of the
Product, which shall be fixed as liquidated damages and not as a penalty, and shall be the
complete and exclusive remedy against the Manufacturer.

Warning: The user should follow the installation and operation instructions and among
other things test the Product and the whole system at least once a week. For various
reasons, including, but not limited to, changes in environmental conditions, electric or
electronic disruptions and tampering, the Product may not perform as expected. The user
is advised to take all necessary precautions for his /her safety and the protection of
his/her property.
