ELK-120 4-Channel Recordable Voice and Siren Driver

The ELK-120 v.2 is a versatile 4-channel audio driver designed for professional alarm and notification systems. Configure channels as 2 voice + 2 siren, or dedicate all 4 to voice messaging. Record up to 8 minutes of custom voice announcements in non-volatile memory that persists through power cycles. Choose from three siren options: Classic Yelp Sound, Temporal Coded Horn, or Pulsing Industrial Horn. Trigger siren and voice channels in sequence, with each set to play once or repeat continuously. The ComboTrigger feature intelligently handles single alarm outputs with pulsing options—automatically sounding the Temporal Coded Horn fire signal when triggered. Built-in microphone simplifies recording. The 24W audio amplifier delivers clear output with adjustable volume control. Dual outputs support both line-level and speaker connections. Trigger channels via momentary or maintained positive voltage inputs. Ideal for fire alarm systems, burglar alarms, and emergency notification applications requiring flexible, reliable audio control.
