Honeywell Intellisense FG-1625 Acoustic Glassbreak Sensor 25 Ft.

Hammering steel next to these sensors will damage them. I had one that gave me false alarms, after I had repeatedly set off the sensor with extremely loud noise. If you must make extremely loud noise around these units, consider an ear muff or something to cover the sensor. The replacement is now working without any problems. Highly recommended, these are excellent glass break sensors!

This is the sensor that ADT recommends for replacing wired sensors in their systems.Installation is straight forward. There are four wires to connect:V+ Red power wireV- Black wire, was G for Ground on old sensorC Yellow wire (Common)NC Blue wireBe careful not to touch the two power leads as you remove them from the old sensor and install them on the new one or you’ll blow a fuse in the alarm system control cabinet. Glad I had a spare.

i've had the older version of these for well over a decade and they started to false. this is my 2nd purchase and like the first one, it made a difference. just hope it works when and if we ever need it.

Easy to instal and works as designed

I have tried a few routers and this router with 2 satellite is the best. I have 1g coming into my large house and test at 700+ at even the most remote areas, 900+ within 30 feet.

Too difficult to installNo customer support

If you are looking for a hardwired glassbreak this unit works great. We test them in the field with a glass break simulator and it works from the 25' as stated.

I purchased this unit to replace a defective one in my alarm system. The alarm company wanted $150 for the sensor plus installation. The installation took about 15 minutes and the unit is configurable for most alarm systems. Noise detection sensitivity is also programmable via two switches inside the unit.
