INTERIOR SENSORS
**************************************************************************
NOTE: Show sensor patterns and installation details
on drawings. Add requirement for additional site
specific conditions such as furniture/equipment
layout within protected areas, hazard location area,
type of hazard, class, and group. Remote test
capability should be used only when required by
governing regulations or when sensors are installed
in hard to reach areas. Within the U.S., the FCC
regulates the operating frequencies of all microwave
sensors. Other countries have their own
frequencies. The designer must determine what
