detection are involved, false alarm rates are reduced when configured in the "AND"
condition (both microwave and PIR sense an intruder). Dual-technology sensors can
only be used in a SCIF, vault, or secure room if the technologies operate in an "OR"
configuration (either the microwave or PIR sense an intruder). Therefore dual
technology sensors are not recommended for this application.
5-3.9.1 Dual-technology sensors act as a detection means for stay-behind covert
intruders. Table 5-1 provides application notes for interior IDS sensors.
