Glass break sensor brown Features: Evaluates the frequency and amplitude of typical ultrasonic signals that occur when glass breaks or is damaged. Break energy is converted into electrical signals using a piezoceramic oscillator to activate the wired alarm signal. The alarm line opens for approx. 0.5 to 5 s in the event of an alarm, depending on the type of glass. Notes: When connecting to the wireless magnetic contact, the 200 k resistor included with the wireless magnetic contact must be used.
