2.7.3.2
Remote Test, Strain Sensitive
A remote test capability shall be provided. The remote test hardware may
be integral to the sensor or a separate piece of equipment. The remote
test shall be initiated when commanded by the alarm annunciation system.
The remote test shall excite the sensing element and associated electronics
causing an alarm signal to be transmitted to the alarm annunciation system.
The sensor stimulation generated by the remote test hardware shall
simulate a standard intruder moving within the sensor's detection pattern.
2.7.4
Pulsed Microphonic Coaxial Cable Sensor
The microphonic cable sensor shall detect induced mechanical vibrations in
fence structure and fabric resulting from climbing, cutting, and lifting
caused by a standard intruder, while rejecting other vibration frequencies.
Upon detecting intruder-based frequencies, the processor module shall
transmit an alarm signal to the alarm annunci The sensor shall consist of
a processor module (PM) using Digital Time Domain Reflectometry (DTDR),
which sends a pulse down the sensor cable; monitoring and processing
reflected pulses indicating the location of an intruder event to within 3
meters 10 feet. Multiple processor modules may be networked together to
provide detection and tamper information to the ESS. The processor module
shall have the capability of monitoring two 200-meter 656 ft lengths of
cable. The system shall accommodate up to eight PMs and provide display
for up to 50 display segments or up to 70 zones. The exterior jacket of
the cable shall be ultraviolet radiation resistant, and provide two
additional sense wires in the dielectric keyway in addition to the normal
center conductor. The cable shall be supervised by the signal processor to
protect against tampering. Ultraviolet radiation resistant carbon
impregnated plastic tie wraps shall be provided for installation of the
sensor cable to the fence. A PC shall be used to configure the initial
free format zoning and sensitivity leveling using software.
2.7.4.1
Microphonic Coaxial Cable Sensor Graphic Display
The Microphonic system shall have the capability of providing a computer
graphic map to identify and display specific event locations to within 3
meters 10 feet. The PC shall have the capability of calibrating the cable
and defining/redefining alarm zones throughout the life of the system.
2.7.4.2
Test Indicator, Microphonic Coaxial Cable Sensor
The sensor shall be equipped with a test indicator if it is an integral
function of the sensor signal processor.
2.7.4.3
Remote Test, Microphonic Coaxial Cable Sensor
A remote test capability shall be provided. The remote test hardware may
be integral to the sensor or separate piece of equipment. The remote test
shall be initiated when commanded by the alarm annunciation system. The
remote test shall excite the sensing element and associated electronics
causing an alarm signal to be transmitted to the alarm annunciation system.
The sensor stimulation generated by the remote test hardware shall
simulate a standard intruder moving within the sensor's detection pattern.
2.7.5
Fiber Optic Cable Sensor
a. The fiber optic cable fence sensor system shall function as an
electronic perimeter intrusion detector. The system shall detect a
