A sensor made of conductive ceramic enamel is applied to the glass surface using a screen-printing process and connected to the alarm system’s electrical circuit.
When the glass is struck or broken, cracking causes the circuit to be interrupted, instantly activating the alarm.
The sensor does not affect visibility and remains completely invisible to users. At the same time, it is resistant to false triggers and does not respond to movement inside the protected area.
This solution is designed for facilities with high security requirements, such as: banks and currency exchange offices, jewelry stores, archives, military and police facilities, industrial plants, residential buildings.
Alarm-loop glass can be installed in windows, display cases, entrance doors, and internal partitions—combining the function of standard glazing with an active alarm system.
We supply alarm-loop glass in various structural configurations, including:
Products are available in thicknesses from 4 to 15 mm (tempered float glass and body-tinted glass) and comply with the relevant standards: PN-EN 12150, PN-EN 12543, PN-EN 14449, and PN-EN 1279.
