Dual Technology Units

Some manufacturers have combined vibration and sound detectors into one unit that will not activate unless both are detected. These units may be used where the normal conditions would cause a single technology detector to generate false alarms. When using these units remember that any window coverings will also affect their performance, so make sure that the final testing is performed with them closed.
