The Acoustic Glass Break Sensor listens for the specific sound of breaking glass across several glass types and thicknesses. It uses dual-frequency detection to verify both the low thud of impact and the high-frequency shatter, reducing false alarms while ensuring genuine break-ins are detected instantly.
! | NOTE While the sensor minimizes false alarms when the system is armed in Away mode, unusually loud sounds like pots falling or very loud music may trigger it when you're home with the system in Home mode. You can reduce sensitivity to lower this risk — see Sensitivity Settings below. |
Parts overview
Part | What it does |
1. Green LED | Monitors low-frequency sounds |
2. Red LED | Monitors high-frequency sounds. Both must trigger for an alarm |
3. Microphone | Picks up glass break sounds up to 25 feet away |
4. DIP Switch | Adjusts sensitivity (factory-set to maximum range) |
5. Battery Compartment | Houses the CR123A 3V Lithium battery |
6. Pairing / Test Button | Press once to send pairing signal; use to test the sensor |
7. Tamper Switch | Activates if cover is opened or device is removed from mounting |
8. Breakaway Area | Knockout mounting holes. Detaches to activate tamper if sensor is forcibly removed |
Pairing your Acoustic Glass Break Sensor
1. Insert the battery to power on the device.
2. Open the Abode app and navigate to Add Device.
3. Select the Glass Break Sensor from the device list.
4. Press the Pairing/Test button once to transmit the pairing code to the Hub.
Installing your Acoustic Glass Break Sensor
Where to mount it
• Mount on the ceiling or wall within 25 feet of the glass you want to protect
• The sensor has a 360° horizontal detection angle. One device can cover an entire room
• There must be no obstacles between the sensor and the protected window. Curtains, drapes, tall furniture, and walls reduce detection range
• Mount away from sound sources such as speakers, air conditioners, or motors
• Keep as much distance from windows or exterior doors as possible to reduce interference from outside noise
Adhesive mounting
1. Clean the ceiling or wall surface thoroughly.
2. Apply the included double-sided tape to the back of the sensor.
3. Press firmly onto the surface for 30 seconds.
Screw mounting
1. Use the Breakaway Area knockouts on the back cover as a template to mark screw positions.
2. Drill holes and insert wall plugs if needed.
3. Screw the back cover to the wall, then attach the sensor main body to the cover.
Sensitivity settings
Two DIP switches on the sensor let you adjust detection range and sensitivity. The factory default is maximum range. Reducing sensitivity lowers the detection range but reduces the chance of false alarms in occupied spaces.
✓ | TIP Refer to the sensitivity chart included in the product packaging for DIP switch combinations and their corresponding detection ranges. |
Battery
The sensor uses a CR123A 3V Lithium battery. When the battery is low, a notification will appear in the Abode app.
When replacing: remove the old battery, press the Pairing/Test button a couple of times to discharge any remaining voltage, then insert the new battery.
