Voice Alerts When Garage Door Opens

Gain immediate and specific voice alerts when your garage door opens with the STI Wireless Garage Sentry Alert with Voice Receiver. This wireless alert kit saves you time when responding to alerts and emergencies within your home by delivering selectable word alerts to tell you exactly what is happening in your home.

  • Create custom voice alert phrases or choose tunes for specific alerts
  • Supports up to 4 STI wireless sensors, 4 LEDs indicate active zones
  • Transmission range up to 1,000 feet
  • Supervised for low battery and signal reception
  • Mounts with double-sided tape or screws

The STI Garage Sentry Sensor is an advanced wireless transmitter that can trigger an alert in three different ways: internal magnetic sensor, internal tilt sensor, or external switch.

  • Magnetic: Triggers when sensor and magnet are separated by at least 1-1/3 inches.
  • Tilt: Triggers when sensor is tilted more than 45° From the vertical position.
  • External Switch: Terminals must first have a closed circuit. An open circuit triggers an alert signal.

When the monitored garage door is opened, the Garage Sentry Sensor will signal your connected wireless Voice Receiver to alert you. Although the sensor is intended for indoor installation, it can be used outdoors by mounting with silicone sealant on the wire and screw hole knockouts. The contact also includes an 18-inch lead for irregular installations.

The selectable words can be programmed in sets of up to four to create a custom message (i.e. "Garage + Door" or "Emergency + Door + Alert", etc.). There are also four LED zone indicators (latching or momentary) to further help you identify which sensor was triggered. With its included power adapter, the receiver plugs into any standard electrical outlet in your home, up to 1,000 feet away from the connected sensors. It can be mounted on a wall, or simply placed on a tabletop. Programming is simple with voice prompts.

Installation Details

Place the Voice Receiver onto a flat surface within 1000 feet line of sight range of any connected sensors. Place the Garage Sentry Sensor components onto the garage door frame and door itself.
