What must an installer consider when installing a glass break detector?

When installing a glass break detector, it is crucial to consider that heavy drapes may affect the performance of the detector. Glass break detectors work by sensing the specific sound frequency generated when glass shatters; however, heavy drapes can dampen or muffle these sounds, potentially leading to false negatives where actual glass breaking occurs but is not detected. Proper placement of the detector is essential to ensure it can effectively pick up the sounds of breaking glass; being aware of physical obstructions like heavy drapes helps optimize the detector's functioning.

Other factors, while relevant to the overall installation process, are less critical than understanding how environmental elements, like heavy drapes, impact the sensitivity and operation of the glass break detector. For instance, weather conditions are more pertinent to outdoor sensors, while the size and number of windows influence coverage and system design but do not directly affect the specific functionality of a glass break detector in the way that obstructive materials do.
