System Sensor WBB Weatherproof Back Box-Red P/N: S000760K04

All System Sensor weatherproof wall-mount horns and horn/strobes can be surface mounted or flush mounted when used with the System Sensor WBB.

The weatherproof or outdoor notification appliance must be used with the System Sensor WBB back box when installed in applications requiring the appliance to be weatherproof or outdoor-listed. In such applications, using a back box other than the System Sensor WBB will void the UL designation.

• Complete field wiring.
• Remove paper liner on plate gasket
