    Product overview and specifications for the STI Wireless Alert Series with Voice Receiver, including the STI-V34400 Wireless Universal Alert — a wireless monitoring kit that alerts you by voice when a monitored site is triggered.

    Overview

    The STI Wireless Alert Series wirelessly monitors up to 4 different STI transmitter devices from a single, convenient location. When the included 4-Channel Voice Receiver detects a tripped site, it sounds a programmable voice message identifying which transmitter was activated. The receiver offers ten tones/tunes and 53 selectable words, available in English or Spanish. It is supervised for low battery and signal reception and operates up to 1000 feet (line of sight).

    Typical monitoring uses: open/closed garage door, mail delivery, car in the driveway, fence gate, medicine cabinet, and indoor or outdoor areas.

    How It Works — Wireless Alert Series Family

    • Wireless Driveway Monitor (STI-V34100 solar / STI-V34150 battery) — detects a vehicle entering or leaving a driveway via a metallic-object sensor.
    • Wireless Mailbox Alert (STI-V34200) — sounds a voice message when the mailbox door is opened.
    • Wireless Garage Sentry® Alert (STI-V34300) — announces garage door open/closed status.
    • Wireless Universal Alert / Wireless Door Chime (STI-V34400 / STI-V34450) — alerts when a monitored site (medicine cabinet, fence gate, window, shed, etc.) is tripped.
    • Wireless Doorbell Button Alert (STI-V34600) — button sends a wireless signal to the receiver when pressed; up to 500 ft range.
    • Wireless Motion Detector Alert (STI-V34700 indoor / STI-V34760 outdoor) — sends a signal when movement is detected; 3-minute lockout after each trip to conserve battery.
