4. Repeat the test if necessary.
Important:
Room acoustics can artificially extend the range of a glass-break sensor. The specified
range of the PGP922 has been established for worst-case conditions. While the sensor is
likely to function at an additional range, it may miss a minimum output break, or room
acoustics may be changed at some future time, restoring sensor coverage back to the
normal range of 6 m (20 ft).
Do not exceed the rated range of the sensor, regardless of what the tester shows.
