(7) Primary Monitor Console (PMC) Audio Module (Item No. 7). The Primary Monitor Console (PMC) audio

module provides the intercom base station and amplifier. It has a volume control knob and a push-to-talk button.

Power is provided through the 120 vac power supply. Interface with other audio devices is through terminal strips.

q. Sensor Devices (Exterior) (See Figure 1-21).

(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.

(3) Exterior Infrared Perimeter Sensor (EIPS). The Exterior Infrared Perimeter Sensor (EIPS) is a pedestal

mounted, active infrared sensor consisting of a transmitter and receiver in two outdoor Environment post type

housings. The sensor alarms when an infrared beam between the transmitter and receiver unit is interrupted or

beam modulation is disturbed.

(4) Taut-Wire Fence Sensor (TWFS). The Taut-Wire Fence Sensor (TWFS) is a tensioned barbed wire

displacement sensing sensor that detects attempts by a fence climbing intruder. Multiple strands of wire and

tensioning devices are attached to either "vertical" or "Y" (angled) outriggers on the fence. The sensor alarms when

60 pounds or more is applied to any strand of the barbed wire or when any strand is deflected by 6 inches or more.

(5) Fence Mounted Vibration Sensor (FMVS). The Fence Mounted Vibration Sensor (FMVS) is a chainlink fence

mounted sensor that assures continuous detection coverage across the full span of the fence panels, including the

fence post. It consists of vibration-detecting transducers that detect mechanical vibrations caused by intruders

climbing, pulling, tugging, or cutting any part of 200 meters of fence paneling.

(6) Ported Coaxial Cable Sensor (PCCS). The Ported Coaxial Cable Sensor (PCCS) detects intruders crossing a

detection zone by transmit and receive cables that are buried in parallel along a perimeter. A disturbance in the

electromagnetic field between the cables causes the sensor to alarm.

(a) With line amplifiers, the sensor can protect 1600 meters of perimeter.

(b) Without amplifiers, the sensor can protect 800 meters of perimeter.

(7) Strain Sensitive Cable Fence Sensor (SSCFS). The Strain Sensitive Cable Fence Sensor (SSCFS) is an

intrusion detection sensor for outdoor perimeter and interior security. It is a passive detector that is mounted on

chainlink or weldmesh fences, on interior surfaces. It is designed as a primary sensor for medium security

applications of a secondary sensor for high security applications.
