Voice Recordable
Annunciator Module
ELK-124
PRINTEDINUSA L332 0101
Four (4) Channels, 30 Seconds Each
APPLICATION:
The ELK-124 is a 4 channel custom recordable
voice annunciation module. Recordable chan-
nels provide 30 seconds of message each, or
they may be combined into a maximum of 120
seconds on a single channel. The channels can
be configured to play once or to repeat endlessly.

InstallationandOperation
OVERVIEW
The four (4) voice message channels on the ELK-124 are
stored in non-volatile memory and may be re-recorded as
needed. Each channel may be activated by a Positive (+)
11 to 14 Vdc input supplied from a control panel or other
switched source. Channel 1 features a Neg. (-) trigger
via the -C1 input as explained in these instructions.
CAUTION: Use of the ELK-124 as the primary
annunciator for emergency applications is not
recommended. Supplimentary or secondary
annunciator use is subject to the approval of
the local Authority Having Jurisdiction.
INPUTCONNECTIONS
[+12V] Connect to positive (+) side of a 12Vdc power
source. This input is required ONLY if the trigger
sources for channels 1 thru 4 are current limited to
30 mA or less, OR if the -C1 input trigger is being
used. Nominal operating range is 11 to 14Vdc.
[-NEG] Connect to negative (-) of a 12 Vdc power source.
[+C1] Channel 1 positive (+) 11 to 14 Vdc input trigger.
[+C2] Channel 2 positive (+) 11 to 14 Vdc input trigger.
[+C3] Channel 3 positive (+) 11 to 14 Vdc input trigger.
[+C4] Channel 4 positive (+) 11 to 14 Vdc input trigger.
[-C1] Channel 1 negative (-) input trigger. For control
panels (such as DSC) that have a switched
negative alarm output. Negative input triggering is
only available for channel 1.
NOTE: To sequentially playback multiple channels,
apply and maintain voltage triggers to multiple inputs.
[Speaker] Connect to 8 Ohm speakers. (Max. 4 Ohm load)
JumperOptions
JP1) MIC, for recording with the on board microphone.
PRG, for recording with ELK-129 computer interface.
JP2) 1SHOT, limits playback to one time per trigger.The
trigger for the channel must then be removed and
re-applied before the message will be played again.
REPEAT, message continously plays back for as
long as the input trigger is applied.
JP3) DIS SW, disables the record pushbutton switch and
prevents accidental recording.
EN SW, enables the record pushbutton switch.
JP4) GT30, enables record and playback of messages
greater than 30 seconds with message recording
overflowing** into the next channel.
30SEC, messages cannot overflow into the next
channel and are limited to 30 seconds.
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. See Figure 2.
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).
** Voice Record Time
If jumper JP4 is in the 30SEC position, maximum record
time is 30 seconds per channel. In the GT30 position,
messages longer than 30 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.
WARNING: When a message exceeds 30 seconds and
overflows into the next channel (Jumper JP4 in the GT30
position), any attempt to record a message into that next
channel will automatically overwrite and destroy the
overflow part of the previous channel's message.
RecordingVoiceMessages
Place jumper JP1 in the MIC and jumper JP3 in the ENSW
position to enable the on-board microphone and record
switch. Place jumper JP2 in the REPEAT position to allow
continuous loop playback. If the message is longer than
30 seconds, place jumper JP4 in the GT30 position.
Activate the desired channel by applying a positive (+) 11
to 14 Volts DC to the input (+C1,+C2, +C3, or +C4). The
ELK-124 will playback the message (if any) that was
previously recorded. While the message is playing, press
and hold the record switch SW1. When the Red REC/
EOM LED comes on, speak clearly into the on-board
microphone. Silently release the record switch at the end
of the message. The new message will then playback.
Remove the trigger input to stop the playback. To change
the message or to correct a mistake repeat the above
procedure. To record another channel apply the trigger
voltage to that channel and repeat the above procedure.
Messages longer than 30 seconds will overflow record
into the next channel (provided JP4 is set to the GT30
position) but must be played back from the channel
where the recording began.
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. If this happens, the trigger
input must be removed and re-applied to start playback.
Volume and Current Adjust
Turning the Volume Increase knob clockwise in-
creases the speaker 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 supply. Maximum Current is approximately 1.2
amps with a 8 ohm speaker, 1.8 amps with a 4 ohm
speaker load.
ComputerSound Card Interface(ELK-129)
The ELK-124 may also be programmed using a personal
computer equipped with a stereo sound card and the
ELK-129 Sound Card Interface. Plug the ELK-129 into
connector J1 (CH 1+2 PRG) for channels 1 and 2, or
connector J2 (CH3+4 PRG) for channels 3 and 4. Place
jumper JP1 in the PRG position to disable the on-board
microphone. Then follow the ELK-129 Instructions.
