Bosch W-HNR W-HN Wall-mount Horns Wall horn 2-wire 12/24V red F.01U.143.891

The W-HNR Cooper Exceder Horn features 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 operations, the universal mounting base, and multiple mounting options results in a reduced cost of ownership. This horn provides 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. It can also be pre-wired to allow full testing of the circuit
