RISCO Group is proud to present a new family of products, External Sounders. RISCO Group's External Sounders are the first in the market to include a Surface Light Technology Strobe (SLT™) that has an extremely long lifetime and low power requirements, compared to xenon or halogen lamps used in most strobes. RISCO Group's External Sounders can be connected to any control panel or installed on the bus of ProSYS Integrated Security Systems. When installed with ProSYS, the External sounders can be remotely diagnosed and controlled via the upload/download software or the keypad.
