System Sensor WTPW Weatherproof Plate for Flush Mounting White

System Sensor WTPW Weatherproof Flush Mounting Plate White

Overview

The System Sensor WTPW is a white NEMA 3R-rated weatherproof flush mounting plate for outdoor SpectrAlert Advance horns, strobes, horn strobes, speakers, and speaker strobes. This accessory solves the installation challenge of mounting audible-visible notification appliances directly to hard surfaces (brick, ceramic tile, concrete, masonry) while maintaining weatherproof integrity. The flush-mount design keeps devices recessed and aesthetically integrated into the building envelope, critical for facilities where surface-mounted brackets would be visually unacceptable or structurally problematic.

Compatibility

The WTPW is designed for all two-wire SpectrAlert Advance outdoor devices. It works with System Sensor horns, strobes, horn strobes, chimes, and speaker strobes in the SpectrAlert Advance family. The plate mounts easily to the universal SpectrAlert Advance mounting base, enabling both wall and ceiling installation. Confirm your specific notification device is a SpectrAlert Advance model before ordering.

Installation Notes

Rated NEMA 3R for outdoor use across −35°F to 151°F operating temperature, meaning rain and wind are handled, but full submersion or continuous spray is not in scope. The plate is designed for flush mounting to solid surfaces including brick, ceramic tile, concrete, and masonry brick. Installers should verify sufficient backbox depth on the wall to accommodate the recessed mounting profile. No ground faults are introduced by the flush-mount design, simplifying wiring verification in supervised systems.
