Multi-Channel Recordable Voice and Siren Driver Module

ELK-120 v.3 (Version 3)

The ELK-120 v.3 features 4 channels that can be configured as 2 channels of siren and 2 channels of voice, or all 4 channels can be used for voice. Either way the voice channels are fully recordable and are stored in non-volatile re-programmable memory. Total time of recording is 8 minutes. The Siren channels offer a choice of: Classic Yelp Sound, Temporal Coded Horn, or Pulsing Industrial Horn. The siren sounds can be triggered in sequence with the voice channels. The channels can be configured to play once or to repeat endlessly. Two channels support our unique ComboTrigger™ feature, especially designed for controls that have a single alarm output with a pulsing option for fire or burglary. When pulsed, the Temporal Coded Horn fire signal is sounded. The optional ELK-129 Computer Interface may be used to download .WAV sounds from a PC to the ELK-120. Also available is the ELK-124 offering eight recordable voice channels of 1 minute each.
