(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 also a

chainlink fence mounted sensor. It consists of strain sensitive coaxial -transducer(s) that detect mechanical vibrations

caused by intruders climbing, pulling, tugging or cutting any part of 100 meters of fence line. The sensor can also

interface with and monitor two adjacent 100 meter segments of cable.

(8) Balanced Magnetic Switch (BMS) (standard and low profile). The Balanced Magnetic Switch (BMS)

detects the opening of doors, including roll up doors, and windows. The Balanced Magnetic Switch (BMS) will alarm

when the separation between the magnet and switch assembly changes by 0.80 0.40 inches on any plane or when the

local magnetic field has a positive or negative difference from the initial adjustment.

(9) Passive Ultrasonic Sensor (PUS). The Passive Ultrasonic Sensor (PUS) detects ultrasonic energy generated

by drills and other intrusion tools during attempts to penetrate through the perimeter (walls, doors, window, ceilings) of

the protected area.,

(10) Vibration Sensor (VS). The Vibration Sensor (VS) detects vibrations generated during attempts to penetrate

through the perimeter of the protected area.

(11) Microwave Motion Sensor (MMS). The Microwave Motion Sensor (MMS) detects intruder motion within a

protected area. It has a single antenna Doppler sensor operating at microwave frequencies.
