1.1 Description and Capabilities

The SP-5A is an advanced 4-channel record/playback device for
short voice messages. A different message can be recorded on
each of the 4 "channels", and each channel can be played back
separately by triggering the corresponding input. A unique design
feature allows the number of messages at one site to be
increased virtually without limit by cascading any number of SP-
5A units (Para. 1.6).
The total available recording time for all 4 messages is 90
seconds. For maximum efficiency, each outgoing message can
be composed of a short "individual" message (alarm, fire, etc.)
and a longer "common" message (location, address or alert
signal). The common message can be joined to the beginning or
the end of each individual message, as desired. Upon triggering
one of the 4 channel inputs, the relevant individual message and
the common message are played back in succession, in the
order chosen (Para. 1.3B), and in accordance with the selected
playback mode (Para. 1.3C).
The SP-5A provides 1-Watt audio output that can be applied to a
loudspeaker, or to the Visonic Ltd. 10 W power amplifier AMP-10,
or to a dialer that has special speech processor input. The unit may
be used for verbal reporting of burglar or fire alarms and for making
access control systems and vending machines "speak out". It may
also provide automatic playback of warnings, announcements,
guidance and advertisements in elevators, stairwells, corridors,
exhibitions, museums, etc.
Playback from each channel can be triggered by motion detectors
or any type of momentary or on/off switch. The channel inputs
can function with normally open or normally closed switches
(Para. 1.4A).
A microphone, RECORD pushbutton, volume control potentio-
meter and LED status indicator are included on board (Fig. 1). An
audio source selector permits the installer to choose between
recording speech directly with the internal microphone or using a
pre-recorded message from an external audio source such as a
tape recorder. The SP-5A recognizes priority levels and will
therefore interrupt a lower priority message in favor of a higher
priority message (Para. 1.4B).
The SP-5A is suitable for mounting within a host system cabinet
or inside a loudspeaker housing. Two units may be mounted in
an optional plastic cabinet - model UPB-3. Operating power is
drawn from the host system or from an external 12VDC supply.

1.2 Message Structure

The SP-5A can store four separate individual voice messages
plus a common message linked to all 4 channels. The overall
recording time must not exceed 20 seconds (or 90 seconds as an
option). The common message may be used to indicate the
location of the particular SP-5A or to identify its user or to play an
alert signal. The 4 individual messages provide information
associated with the specific channel inputs.
Suppose the SP-5A is installed in an imaginary warehouse
known as Acme Storage and wired to report verbally via an
automatic dialer. Four distinct alarm messages could be recorded
for transmission and linked to a common message, as
demonstrated in the following example:
Chan. Combined Message (common + individual)
1 Acme Storage, fire alarm
2 Acme Storage, intrusion alarm
3 Acme Storage, flooding alarm
4 Acme Storage, power failure
In this example, the common message is "Acme Storage". The
individual messages relate to the type of alarm associated with
particular channel input.

Installation Instructions

Memory space (recording time) can be divided freely between the
four individual messages and the common message, provided
that the total accumulated recording time of all 5 messages will
not exceed the 20-second time limit. Omitting a certain channel
message or the common message will leave more memory space
for the rest of the messages.

1.3. Selectable Functions
Figure 2 presents the Function Control 4-lever DIP switch. The
tasks of all four switches are explained in the following sub-
paragraphs.
A. Play/Record (SW1)
The PLAY/REC switch (marked 1) enables
you to determine the standby state of the SP5.
ON: The unit will stand by for recording (see
Section 4 for recording procedure).
OFF: the unit will stand by for playback.
Playback will start if channel input is triggered,
or a channel DIP switch is set to ON.
B. Playback Order
The COM MSG switch (marked 2) determines
which part will be played back first: the indivi-
dual channel message or the common message.
ON: The common message will be played back first, and then the
individual channel message.
OFF: The individual channel message will be played back first,
and then the common message.
C. Playback Mode (SW3, SW4)
The PLAY MODE / MEMORY ERASE selectors (levers 3 and 4
of the Function Control switch) can be set to four different
combinations as follows:
3 4 Resultant Mode
ON ON Erase mode - all recordings are erased (if REC
button is pressed 3 times*).
OFF OFF Single playback (non repeating) in response to
momentary or continuous triggering of any input.
ON OFF Repeated playback with timeout after 3 minutes,
in response
triggering of any input.
OFF ON Repeated playback for as long as the channel
input is kept triggered, but subject to the 3-
minute timeout.
The button must be pressed for at least 1/2 second each time -
*
all within 4 seconds.
