Safety Technology Int'l STI-3353 Wireless Chime Receiver

Product Description

The Safety Technology Int'l STI-3353 is a wireless chime receiver designed to provide audible alerts in commercial and residential alarm, access control, and notification systems. The unit receives wireless signals from compatible transmitters and converts them into chime tones, giving building occupants and staff a clear, non-intrusive audio notification. The STI-3353 is intended for installation by licensed security, electrical, or low-voltage contractors as part of a broader wireless notification or alert system.
