Safety Technology Int'l Inc STI-3350 Wireless Doorbell

Product Description

The SAFETY TECHNOLOGY INT'L INC STI-3350 is a wireless doorbell unit with a bundled receiver, designed for residential and light commercial entry-point notification. The system transmits a wireless signal from the push-button transmitter to the receiver unit, eliminating the need for low-voltage doorbell wiring between the door and the chime location. This makes it a practical solution for retrofit installations where running new wire is not feasible. Licensed electricians and general contractors typically handle installation in new construction, while experienced technicians handle retrofits in existing structures.

The STI-3350 is suited for residential entryways, commercial storefronts, and light-duty access notification applications. It is particularly useful in retrofit scenarios where existing wired doorbell infrastructure is absent or where wire routing through finished walls is impractical. The included receiver means the kit arrives ready for a complete installation without sourcing additional components separately.
