Installation instructions for the 2GIG-GB1-345 Glass Break Detector, a fully supervised, tamper-protected sensor with dual-stage glass break detection for 2GIG Control Panels.
Installation instructions for the 2GIG-GB1-345 Glass Break Detector — a fully supervised, tamper-protected ceiling or wall-mounted glass break sensor with dual-stage detection, for use with 2GIG Control Panels.
The Glass Break Detector offers 15 feet maximum detection range, 360° maximum horizontal sensing angle, and dual-stage glass break detection (thud + crash acknowledgment).
Scroll between options with the left/right arrows; move to the previous/next prompt with up/down arrows.
Tip: For wall mounting, orient the test button down, nearest the floor. When wall-mounted, the detector is designed to provide coverage on the opposite or adjacent windows — not on windows on the same wall as the detector.
Important: When attaching the detector to the base, match the alignment marks and twist clockwise. If batteries are not present, the red tabs must be held away from the detector.
Push and hold the test button for 5 seconds and release — the red LED appears while pressed, and the green LED blinks twice indicating RF test mode for 90 seconds.
Note: Perform a full system test (per the User Guide) at least once a year.
Minimum glass size for all types is 11" x 11" (28cm x 28cm) square; glass must be framed in the wall of the room or mounted in a barrier of 36" (0.9m).
| Glass Type | Min to Max Thickness |
|---|---|
| Plate | 1/8 in. to 1/4 in. (3.2 mm to 6.4 mm) |
| Tempered | 1/8 in. to 1/4 in. (3.2 mm to 6.4 mm) |
| Sealed Insulating† | 1/8 in. to 1/4 in. (3.2 mm to 6.4 mm) |
† Sealed insulating glass types are protected only if both plates of glass are broken.
If a supervised detector's battery is low, a low battery notification appears on the Control Panel's touch screen — replace the battery immediately, using only the recommended replacement type.
Remove the cover by twisting counterclockwise, then replace the battery.
Warning: Improper handling of lithium batteries may cause heat, explosion, or fire. Replace only with the same or equivalent battery type. Do not recharge, disassemble, or dispose of in fire. Dispose per local waste/recycling regulations. Keep away from small children; seek medical attention if swallowed.
California only: Perchlorate warning applies to Manganese Dioxide Lithium cells sold/distributed in California — special handling may apply. See dtsc.ca.gov/hazardouswaste/perchlorate.
