STI STI-3353 Wireless Chime Receiver
Overview
The STI-3353 is a wireless chime receiver designed to integrate audible and visual notification into distributed access control deployments. Operating at 9VDC, it receives wireless signals from compatible STI transmitting devices and delivers alert functionality across multi-door entry points without hardwiring signal lines between transmitter and receiver locations. This architecture reduces installation labor in retrofit scenarios and environments where running dedicated alert wiring is impractical.
Compatibility
The STI-3353 pairs with STI wireless door control and strike systems within the same product family. Verify transmitter model compatibility before deployment — the receiver must be provisioned to recognize its paired transmitter frequency and address codes. Integration with third-party access control panels depends on the panel's ability to trigger or control the STI wireless ecosystem; confirm this during design phase, not at commissioning. Works in conjunction with access control platforms that support wireless auxiliary devices.
Installation Notes
The STI-3353 requires a dedicated 9VDC power supply — do not rely on PoE or borrowed auxiliary power from other building systems. Position the receiver where it has clear line-of-sight or radio path to transmitters; obstructions (metal frames, concrete walls) degrade signal range. Mount the unit away from high-noise RF environments (large switching power supplies, industrial machinery, radio transmitters) to avoid false triggers or missed alerts. Wire the power supply with appropriate gauge and strain relief; follow local electrical code for auxiliary 9VDC circuits.
