Recordable Voice Module

ELK-124 v3

The ELK-124 is a recordable voice module with 8 record/playback channels and up to 8 minutes of total record time. Voice or music may be recorded making this product ideal for applications such as: telephone on-hold announcements, security or access control warnings, museum narrations, and more. There are two ways to record: 1) With the built-in microphone and push to record button, or 2) With an optional ELK-129 PC Sound Card Interface to transfer .wav files from a PC. Each channel may be triggered via a positive or negative voltage input, or a trigger switch. Sound is delivered through a 24 watt Speaker output as well as a line-level “RCA” jack for use with external amplifiers, audio equipment, or paging systems

Instructions

All 8 channels of the ELK-124 are 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 recordings 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 v3

Connections

Power Connections [+12V] Connect a 12VDC power source to the +12V and NEG terminals. [NEG] Operating voltage range is 11 to 14VDC, and the max. operating

current may reach 1.8 Amps depending on the speaker load and the volume level selected. By connecting the ELK-124 to a full time power source the individual channels may be tripped with either a Pos or Neg input, and the trigger source may be low curren and low voltage.

Channel Trigger Inputs ( 8 total ) [C1] These inputs are used for activating each of the respective thru recorded channels. Each input may be jumper selected so that [C8] the trip input is either a positive or negative. Refer to the

Channel Polarity Jumpers located above each terminal.

To trip with a positve voltage set the Channel Polarity jumper to "+" and apply + 12 Volts DC. Make certain that the NEG power connection is connected to the power source.

To trip with a negative voltage set the Channel Polarity jumper to “-” and apply - 12 Volts DC. Make certain that the +12v power connection is connected to the power source.

Speaker Connection

Connect to 1 or more 8 Ohm speakers. WARNING: The Max. combined total load on this output must not exceed 4 Ohms.

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, REC led flashes when 60 secs is reached. This helps

prevent messages from accidentally overflowing into the next channel. >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.

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. To 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.

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).

Installation & Hookup Examples

Basic Hookup

Only a +12 Volt D.C. power source is needed to play any of the 8 channels. In this configuration, the playback will stop as soon as power is removed from channel C1 since the ELK-124's power terminal (+12V) is not connected to +12V. Set the Channel Polarity jumpers to "+" for each channel that will be activated with positive voltage.
