Bosch W-HNR Wall-mount Horn (Two-wire, 12/24 V, red)

The Cooper Wheelock Exceder Series Horns feature a sleek modern design that incorporates high reliability to minimize current draw. The reduced current draw allows for a greater number of devices on the two‑wire notification appliance circuit. This, in combination with no tools needed for changing settings, voltage test points, 12 V or 24 V DC operation, the universal mounting base, and multiple mounting options results in a reduced cost of ownership.

These horns provide three sound settings on each appliance. All the switches to change these settings can be set without a tool and are located behind the appliance to prevent tampering. The separate universal mounting base can be easily mounted to five industry‑standard back box types.

They can also be pre‑wired to allow full testing of the circuit wiring before the appliance is installed and the surface finished. These wall‑mounting horns also feature voltage test points for taking readings with a volt meter for troubleshooting or AHJ inspection.

Key Features:

  • Rectangular white two‑wire horn field‑selectable for three volume options.
  • Sleek modern aesthetics
  • Multiple voltages (12 VDC or 24 VDC)
  • Voltage test points
  • Three horn volume options
  • Universal mounting base
