1.3 Terms and Definitions
The following terms will be used throughout this hardware installation guide, to refer to system
components and modes of operation.
Bridging Clip – A small metal clip used in a punch-down block to short the left-hand columns to
the right hand columns of punch-down terminals.
Collector – This device gathers the tracking data from as many as 24 sensors, processes it as
required, and sends it via the 2-pair collecting network to the concentrator. Each system must
contain at least one collector, and many systems will contain more than one.
Concentrator – This device provides an interface between the 2-pair network that connects
collectors together (the “Collector Network”) and the computer system. It assembles the data from
the various collectors and bundles it for delivery to the host computer. Each system must contain
at least one concentrator, and many systems will contain only one.
Impedance – A measure of a characteristic of wire that is very important when digital data signals
are to be sent over the wires at high speeds. All wires have impedance determined by their makeup
and twisting called the “characteristic impedance” of the wire. Most solid twisted pair wire is
about 100 ohms impedance, and the coaxial cables used are 50, 75, or 93 ohms.
Sensor – A device that gathers infrared light energy and converts it to an electrical signal, which is
then sent over a single pair of wires to a collector.
Sensor Connection – A single pair cable that connects a sensor to a collector port. All of the sensor
connections in a system may be referred to as the “Sensory Network.”
Plenum – Any area that serves as a duct or passage for breathable air. Many office buildings use
the space above the suspended ceiling as a return air “plenum” for the heating and air conditioning
systems. Most laws require any cables that run in an air plenum to be made of materials which will
not burn, or which will not release toxic gases when burned.
Punch-down Block – This device is used to connect sensor wires to the collector in an organized
fashion. A special tool is used to “punch” the wire onto the punch-down block terminals, which
causes the terminals to penetrate the wire insulation and cut off excess wire in one easy step.
Punch-down Blocks are the preferred method of connection for solid wire in telephone systems.
RJ – Acronym for Registered Jack. VIS uses some modular-style connectors identified by their
‘RJ’ designations. RJ-11 is a generic term, often used to refer to a six-position jack, though it
specifically refers to a single-pair connection in a six-position shell. RJ-12 refers to a two-pair
connection in a six-pair shell, and RJ-25 refers to a three-pair connection in a six-pair shell.
