FGW-725 Glassbreak
The FGW-725 is a battery-powered, dual technology glassbreak detector designed to work with virtually any RF (Radio Frequency) transmitter on the market today.
The glassbreak sensor features separate microphones for detecting flex and audio frequencies. The flex microphone is also equipped with an advanced acoustic filter specially designed to prevent microphone overload caused by very loud sounds.
Each microphone is sensitive to different frequencies. The flex microphone is sensitive to ultra low frequencies, the kind generated by a blow to a glass window. The audio microphone detects the higher frequencies of breaking glass.
The sensor's audio technology remains inactive until the flex technology detects a blow to the glass. For an alarm condition to occur, the audio must detect the frequency of breaking glass within a defined time-window after the flex detects a blow to the glass.
Because both technologies must detect and verify glass breakage, false alarms are virtually eliminated.
The FGW-725 is a fully self-contained unit. The transmitter is mounted inside the housing, on the same surface as the sensor's printed circuit board.
For most installations, both the transmitter and the FGW-725 are powered by a common internal battery(ies).
The unit also features clear access to three sides of the installed transmitter, and clear access to the sensor's terminal strip. Wiring is easy, with little risk of wires folding over the transmitter when closing the case.
Included is an installation kit (725-KIT) that contains the fasteners, wires, connectors, etc. to install your transmitter inside the FGW-725 housing and mount the sensor/transmitter unit to a wall or ceiling.
