Description

The Esser 807205R is a loop-powered, addressable acoustic signaling device specifically for use on the esserbus-PLus. Unlike conventional sounders, this “So” (Sounder-only) model is fully integrated into the system’s digital protocol, allowing for individual control, soft-addressing, and remote volume adjustment. It features an integrated short-circuit isolator to protect the loop and supports up to 20 different programmable tones. The device is designed for synchronized operation, meaning all sounders on the same loop will pulse in unison to provide a clear, unambiguous evacuation signal. Its low power consumption allows for a maximum number of devices to be installed directly on the loop without the need for additional power supplies.

Features

  • Loop-Powered Efficiency: Draws all necessary power directly from the fire alarm loop, eliminating the costs associated with external power supplies and additional cabling.
  • Programmable Tone Selection: Offers 20 distinct tones, including the standard DIN tone for Germany and various international emergency signals, selectable via software.
  • Adjustable Sound Pressure: Volume levels can be adjusted in multiple steps via the tools8000 software, allowing for quiet signaling in hospitals or high-output alarms in industrial halls.
  • Full Acoustic Synchronization: Ensures that all devices across the building sound at the exact same frequency, improving the audibility and clarity of the evacuation message.
  • Integrated Isolator: Built-in loop isolator protects the system; if a short circuit occurs on the cable, the device disconnects the fault to keep the rest of the loop active.
  • Decentralized Intelligence: The sounder stores its own configuration and can continue to function in “emergency mode” even if communication with the central panel is lost.
  • Robust Red Housing: The UV-stable, impact-resistant red plastic (RAL 3020) provides high visibility and matches standard fire safety aesthetics.
  • Easy Installation: Fits on the standard IQ8Alarm base system, supporting both surface and flush-mount wiring entries.
