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.

• Rectangular white two-wire horn field-selectable for three volume options.
• Sleek modern aesthetics
• Multiple voltages (12 VDC or 24 VDC)
