Recordable Voice & Siren Driver Module

ELK-124 v.2

The ELK-124 v.2 is an enhanced 8-channel user
recordable voice module with 8 minutes of recording
time for voice or music. It’s ideal for applications such
as telephone on-hold announcements, security and

more. Recording is quick and easy using the built-in
microphone and push to record button. A line-level
output jack allows connection to external amplifiers,
audio equipment, and paging systems. It features
convenient channel activation switches and the ability
to play each channel once or to repeat endlessly .

Instructions

All 8 channels of the ELK-124 v.2 are voice recordable and can hold up to 1 minute of message each. Two or more channels can be
combined into longer messages up to the combined maximum of 8 minutes. The voice messages are stored in non-volatile memory and may
be re-recorded as needed. Each channel may be activated by a Positive (+11 to 14 Volts DC) or by a Negative (pull to ground) trigger
supplied from a control panel or other switched source. Channels are individually jumper selectable for Positive or Negative trigger input
source. Voice messages are stored in non-volatile memory and may be re-recorded as needed.

ELK-124 v.2

[+12V] Connect to positive (+) side of a 12Vdc power source. This input

Connections

is required ONLY if the trigger sources for channels 1 thru 8 are
current limited to 30 mA or less, OR if Momentary or Negative
Triggering is being used. Nominal operating range is 11 to 14Vdc.
(also needed for "Manual Triggers")

[- NEG] Connect to negative (-) of a 12 Vdc power source.
[C1]~thru~[C8] Channel Trigger Inputs.(8)

Positive (+) Voltage Activation
To activate(play) a channel from a positve voltage source, set
it's "Channel Polarity" jumper to "+" and apply 12 Volts DC
between the NEG terminal and the channel input.
Negative (-) Activation
To activate(play) a channel from a Negative (pull to ground)
source, connect the +12V and NEG terminals to a constant
power source, set the "Channel Polarity" jumper to "-" and apply
a switch to ground source to the channel input. This is intended
for controls (such as DSC) that switch the negative of the alarm
output.

[Speaker] Connect to 8 Ohm speakers.(Max. 4 Ohm load)

Jumper Options

JP1) MIC, for recording with the on board microphone.

PRG, for recording with the ELK-129 computer interface.

JP2) REPEAT, permits the voice channel to repeatedly play for as long

as the channel input is activated.
1SHOT, restricts playback of a voice channel to only once per
activation cycle. The channel activation must be removed and
then re-applied before the message will be allowed to play again.

JP3) ENABLE, enables the record pushbutton switch.

DISABLE, disables the record pushbutton switch and prevents

accidental recording.

JP4) <60, messages cannot overflow into the next channel and are

limited to 60 seconds. REC led flashes when 60 secs is reached.
>60, enables recording of messages greater than 60 seconds
with message recording overflowing into the next channel.

Activating The Voice Channels (Playback)

Continuous (maintained) trigger: Apply a positive (+) 11 to 14 Vdc to
terminal C1 for Channel 1, terminal C2 for Channel 2, etc. The message
will playback for as long as the power is applied, provided Jumper JP2
("1SHOT - REPEAT") is in the REPEAT position.

Momentary trigger: Connecting terminals +12V and Neg to a constant
(+) 11 to 14 Vdc power source allows channels to playback with a
momentary trigger input voltage. Most current is drawn from the
constant power source. Current draw from the input triggers will be
approximately 30 mA. In the momentary trigger mode each message is
played through to the end (one cycle).

If jumper JP4 is in the <60 position, the maximum record time is 60

Voice Record Time

seconds per channel. In the >60 position, messages longer than 60
seconds may be recorded by overflowing the message into the
next available channel. When this occurs, the next "overflow"
channel cannot be used as a recordable channel. Any attempt to
record a message into that next channel will automatically
overwrite and destroy the overflow part of the previous channel's
message. Note: If the maximum record time is reached or
exceeded, the red REC/EOM LED will start blinking to indicate that
recording time has halted.

Volume and Current Adjust

Turning the Volume knob clockwise will increase the output
volume. The louder the volume, the higher the current draw. The
volume and current draw may be adjusted to match the current
capability of the power source.

Options for Playback of the Voice Channels

The switches marked "Manual Triggers" are provided for
programming and for user convenience where manual activation of
the channel(s) may be desired. A constant power source must be
connected to +12V and NEG terminals in order to use these
switches.

Recording Voice Messages

Messages may be recorded from the on-board microphone, or
from a PC with a sound card and an ELK-129 interface.

To record from the onboard microphone place Jumper JP1 in the
MIC position, JP2 in the REPEAT position, and JP3 in the RECORD
position. If the message will be longer than 60 seconds, place JP4
in the >60 position. Activate the desired channel either by using
the on-board DIP switches(requires power to be connected to
+12V and NEG terminals) or by applying +12 Volts DC to the
desired input (C1, thru C8). The current message (if any) will start
to play. While it is playing, press and hold the record switch SW1
and speak clearly into the on-board microphone. Note that the
RECORD/EOM LED should light before you begin speaking. T o
minimize any noise, gently release SW1 after speaking. The new
message will immediately be played. To stop the playback turn off
the channel switch or remove the trigger voltage. To re-record the
message, or to record another channel, repeat the above
procedure.

To record with the ELK-129 sound card interface place Jumper
JP1 in the PRG position, and JP2 in the REPEAT position. If the
message will be longer than 60 seconds, place JP4 in the >60
position. Plug the ELK-129 five pin ribbon cable into Programmer
Connector J1. Power the ELK-129 and move the SW1 slide switch to
CH1(this will provide power to the ELK-124). Select the channel to
record with the on-board DIP switch. Follow the instructions for
the ELK-129, Play a "scripted" WAV.
