STI STI-3301 Wireless Doorbell Chime Transmitter
Overview
The STI-3301 is a wired wireless doorbell chime transmitter operating at 9VDC, designed to extend door chime notification capability across distributed access control installations. This unit bridges wired power infrastructure and wireless signal delivery—solving the deployment problem of multi-door facilities where running individual chime notification wires to each entry point is impractical or cost-prohibitive. Install the STI-3301 at the door frame or control panel location to transmit chime signals wirelessly to paired receiver units throughout the building.
Compatibility
The STI-3301 integrates into access control systems requiring wireless chime notification across multiple entry points. It pairs with wireless chime receiver units in the same product family to create distributed notification networks. Verify receiver model compatibility before ordering—the transmitter and receiver must support the same wireless protocol and frequency band. Typical deployment includes one transmitter per door or access point, with one or more receivers in secure control rooms or entry monitoring stations.
Installation Notes
The STI-3301 requires a steady 9VDC power supply. Use a dedicated access control power supply or integrate into existing 9VDC distribution—confirm available amperage before wiring. Wireless range and signal reliability depend on building construction (concrete and metal reduce effective distance) and receiver placement. Install the transmitter at the door frame or in an enclosure near the access reader. Avoid mounting directly against metal surfaces or inside metal cabinets, which will degrade wireless signal. Test wireless connectivity at the intended receiver location before finalizing installation.
