FAQs
Will the GEM-GB Glass Break Detector detect the break of laminated glass composites or multi-pane glass?
Below are the specs for the GEM-GB, including descriptions of the glass types and thickness the GEM-GB is capable of protecting. Please keep in mind that with any glass-break detector, if protecting multi-pane glass, both panes (inner and outer) must be broken in order for an alarm to be generated. Breaking the outer pane only may not generate an alarm.
