g. Sensor Devices (Exterior) (See Figure 1-11).

(1) Exterior Microwave Motion Sensor (EMMS). The Exterior Microwave Motion Sensor (EMMS) is an exterior

microwave perimeter intrusion detection sensor. It is usually located near or between fence lines. The sensor protects a

minimum of 100 meters of fence line and detects intruders crossing the detection zone.

(2) Radio Frequency Motion Sensor (RFMS). The Radio Frequency Motion Sensor (RFMS) covers a large area

with microwave energy. Any change in energy will be detected by the receiving antenna.
