[+12V] If using a constant 12 Volt DC power source, connect the positive
side here. Nominal operating range of the ELK-120 v.2 is 11 to 14 Volts
DC. This input is only required if: A. The -VS negative trigger terminal is
used. B. Momentary activation of the channels is desired. C. The
activating source equipment is current limited to 30 mA or less.
[NEG] Connect to the negative side of the 12 Volt DC power source. Also
connect the negative from external trigger inputs here if they are from
another power source.
[+V1] Positive trigger input for Voice channel 1
[+V2] Positive trigger input for Voice channel 2
[+S3] Positive trigger input for Yelp Siren or Voice channel 3
[+B4] Positive trigger input for Temporal Coded Horn or Voice channel 4
[-VS] Negative trigger input for controls with a switched negative output
[SPEAKER] Connect to 8 ohm speaker. (Max 4 Ohm load)
[Volume Control (R21)] Adjusts volume of the speaker output.
[Activate Channels] Selects channel to be recorded. Power must be
applied to the +12V and NEG terminals to use this switch.
[Record Switch (SW1)] To record a message, set JP1 to MIC, activate
desired channel, press SW1, then speak your message into the on-board
microphone.

Siren with Voice Mode (JP4 = Siren)(for Alarm Applications)
+V1 = 0 to 8 Minute Recordable Message, see note
+V2 = 0 to 4 Minute Recordable Message
+S3 = Yelp Siren
+B4 = Temporal Coded Horn
+S3 and +B4 together = Industrial Horn
-VS = Alternately plays Yelp Siren and Voice 1 message
Pulsing the +V1 input will play Voice 2 message
Pulsing the +S3 input will play the Temporal Coded Horn
Pulsing the -VS input will alternately play the Horn and Voice 2 message
Note: If Voice 1 (+V1) message recording exceeds 4 minutes, it will
overwrite Voice 2 (+V2) message space, thus +V2 becomes unusable
