  • What's Included
  • The Visonic GFD-30 Glass Break Sensor Audio Discriminator and Detector is a flush mounted, glass break audio discriminator sensitive to noises above a cutoff frequency of approximately 5 kHz. The unit is designed to fit into virtually any standard, single-gang electrical switch box. It can also be installed directly in to a prepared space in the wall without a box enclosure. The glass break sensor requires a hardwired 9V DC - 16V DC power connection. You can connect the Normally Closed Relay output to a normally closed detection zone of a home security system or integrate into a home automation system. A built-in potentiometer is located on the circuit board that allows you to set the optimum sensitivity to avoid false alarms triggered by things such as telephones an door chimes. The unit also features test and alarm LED indicator lights to help during the setup process.
