The Honeywell FG1625 is a glass break detector that can be added to any hardwired security system. The FG1625 is part of Honeywell’s IntelliSense family of detection devices. The FG1625 listens for the frequency of broken glass, allow an additional layer of protection for your windows. A maximum range of 25’ allows one glass break detector to protect multiple windows, or even an entire room. With the FG1625, you can detect intruders before they enter your property, as soon as the glass has been breached.

The Honeywell FG1625 can be mounted on the ceiling, wall opposite the glass, wall adjoining the glass, or even the same wall as the glass, as long as it is within 25’ of the protected surface. The FG1625 is equipped with a FlexCore signal processor, which allows for faster, and more accurate detection. Honeywell’s patented technology allows the FG1625 to accurately evaluate each sound signal and only trigger on true broken glass events, minimizing false alarms. The FG1625 is compatible with all types of glass including but not limited to plate glass, tempered glass, wired glass, laminated glass, film-coated glass, and sealed insulating glass. Easily adjust the sensitivity using the dip switches located on the circuit board as per the chart below.

Honeywell FG1625 Sensitivity Configuration

Sensitivity Approximate Range SENS1 SENS2
MAX 25’ (7.6m) OFF OFF
MEDIUM 15’ (4.6m) ON OFF
LOW 10’ (3m) OFF ON
LOWEST 5’ (1.5m) ON ON

Remember, sensitivity can be affected by the acoustics of the room, and how much sound dampening material is present, such as carpet, wallpaper, or heavy drapes covering the protected windows. The other two dip switches configure the LED indicator behavior.

The Honeywell FG1625 uses a four wire connection to the security system control panel. Two wires carry voltage from the alarm panel’s 12V auxiliary power circuit, while the other two act as the data wires and are connected to the zone loop assigned to the FG1625. The FG1625 glass break requires 12mA in standby and up to 22mA maximum when in alarm with the LED active. The FG1625 is intended to detect the shattering of a framed piece of glass in an impact event. If the glass is only cracked, is broken without impact, or shattered by high velocity projectiles such as a bullet, the FG1625’s false alarm protection features may not allow it to pick up those sounds as an alarm.

The FG1625 can be tested easily using the Honeywell FG701 glass break simulator. The Honeywell FG1625 is a first line of defense for your property, allowing instant notification when windows are breached. Glass break sensors are an important part of your security system, allowing additional protection while the system is in stay mode, when motions are not active. Sleep soundly knowing that all of the potential access points to your home are protected. The FG1625 can protect your windows without the need for cumbersome or unsightly security tape or screens.

thank you. i will consider it.
Any 22 or 18 gauge 4-conductor wire should do. Are you planning to have the system monitored? We have low-cost, no-contract plans online at
good. do i need an special cable? it´s my first home alarm system.
Do you mean can you run a wire 60 feet long between a wired VISTA-20P and this wired glass break? If so, yes you can. There shouldn't be any issues with a wire run that long. The glass break's maximum detection range is 25 feet though so depending on where the windows are in the room, you may need more than one detector for a room of that size.
can i connect this sensor with a vista 20p panel at 20 meters? is it posible? it is for a 50 meters square room with big windows.
The FG1625SN is only supported by polling loop alarm panels. Unfortunately, your glass break will not work with the VISTA-20P.
I have a 1625 sim two wire ,how do i hook it up to a vista 20p panel?
