Screamer Electronic Sirens

Screamer sirenThe SCREAMER is available in two different versions, small and large horn. The small horn has an acoustic directivity pattern close to the circle shape with lower acoustic pressure, while the large horn has an elliptical acoustic directivity pattern and higher acoustic pressure.


SCREAMER can broadcast:

  • voice messages and signals from the internal memory (SD card)
  • live voice messages from the external microphone
  • audio signals from various external sources (radio, cell phones, etc.)

The messages are activated by:

  • signals fed to one of the four binary inputs,
  • RS232/RS485 interface by other systems
  • interface through aBUS and other devices from the aSCADA system,
  • wireless technology XBee (requires additional module XBee)
  • line interface via Ethernet (requires TCP/IP module)
  • WiFi interface (requires TCP/IP module)
  • GPRS interface (requires TCP/IP + GPRS module)
