Voice messages are stored in nonvolatile memory and may be re-recorded as needed. Each channel can be activated by a positive (+) 9-14 Vdc input supplied from a control panel or switched power source. [. . . ] The siren inputs are marked +S3 (Siren, Channel 3) and +B4 (Bell, Channel 4). These inputs may be activated separately or combined (activated at the same time) to achieve mixed playback of voice and siren sounds. NOTE: If a pulsing voltage is applied to Channel 3 (Yelp) +S3, the ELK-120 will automatically play the Channel 4 (Temporal Coded Bell) sound. Continuous Loop Playback or One Shot Negative (-) Trigger Input Channel The ELK-120 has one (1)negative (-) trigger input marked -VS, for control panels (such as DSC) that have a switched negative alarm output. This input internally activates Channels 3 and 1 together if a steady input is applied, and Channels 4 and 2 if a pulsing input is applied. For example: when a constant negative (-) is applied to this input, the voice message in channel 1 will be played followed by the channel 3 (Yelp) siren sound. If a pulsing negative (-) is applied, the voice message in channel 2 will be played followed by the channel 4 (Temporal Coded Bell) sound. Jumper option, JP2 ("Close For Single Play") can be used to lockout the voice messages after a single play. The trigger for the channel must then be removed and/or reapplied before the message will be played again. O (Open) C (Closed) Jumper is closed when shorting plug is installed on these bottom two 2 pins. Figure 2 - Jumper Selections Jumper is open when shorting plug is installed on these top two 2 pins. Siren Sounds A choice of three (3) sounds (Temporal Coded Bell, Yelp, and Industrial Buzzer) may be obtained from the siren channels. Applying a positive (+) 9 to 14 Vdc trigger voltage to the specified input(s) will activate the corresponding sound. Terminal +S3 activates the Yelp sound, and terminal +B4 activates the Bell sound. Applying the same trigger to terminals +S3 and +B4 at the same time will produce the Industrial Buzzer sound. Voice Record Time The maximum record time is 10 seconds per channel, or 20 seconds total. The ELK-120 allows one long 20 second message to be recorded into Channel 1 provided Channel 2 is not used. Care must be taken not to exceed the allowable time when recording. If a message recorded into Channel 1 exceeds 10 seconds then do not use Channel 2. If Channel 2 were triggered, only the end of Channel 1's message would be heard. WARNING: If more than 10 seconds is recorded into Channel 1, then any message recorded into Channel 2 will cause part of Channel 1's message to be lost. Mixing Siren Sounds and Voice Messages To combine a siren sound with a voice message simply apply a positive (+) 9 to 14 Vdc trigger voltage to any siren input and any voice input at the same time. EG: To obtain a burglary warning message on channel 1 followed by the Yelp siren sound, simply apply a trigger voltage to channel +V1 and +S3 at the same time. The two channels will alternately play until the trigger is removed. Exception: Voice channels 1& 2 can be set to play only once per activation cycle by placing jumper JP2 ("Close For Single Play") in the closed position. [. . . ] each.
