The transmitter is a miniature, hand-held radio transmitter used to transmit either a distress
or a test signal. The receivers are located throughout the protected area and detect the radio
transmissions from transmitters. Alert units are siren/strobe units activated in the event of an
alarm. Transponders are devices that control groups of receivers and alert units, connected to
them by wire. Each transponder relays alarm and test signals from its receivers to the Central
Console. In addition, the transponder tests for device and wiring faults, and transmits problem
conditions to the Central Console. The Central Console consists of a computer (plus an
optional backup and up to 8 optional workstations) which receives alarm and trouble signals
from the transponders, analyzes the signals, activates strobes and sirens on the alert units,
and produces a display for the Security dispatcher. Each of these system elements is
described more fully in the sections that follow.

The SE3 subscriber transmitter contains a unique code which is associated with the
subscriber at the time the transmitter is assigned. When the subscriber generates an alarm,
this code is sent to the Central Console. The Central Console graphically displays the
subscriber’s location on a map along with the subscriber’s picture, his or her name, and
address.
Transmitting an alarm
In the event of an emergency, the user simply presses and holds the alarm buttons to produce
an alarm. Depending on the installed options, when an alarm is generated within
approximately two seconds, the sounders in any nearby receivers will be activated as well as
the strobes and sirens connected to nearby alert units. The alarm signal is transmitted to the
receivers which in turn relay the alarm signal to the transponder and along to the Central
Console. The Central Console then graphically displays the subscriber’s location along with
the subscriber’s name, vital information (such as a medical condition or disability) and a
picture of the subscriber. Also, once an alarm is initiated, the transmitter commences its autotracking feature.
Auto-tracking
During an alarm, the transmitter automatically resends the alarm signal every few seconds,
constantly updating the Central Console of the subscriber’s location.
Testing
The test mode allows a subscriber to test their transmitter anywhere in the protected area.
When the user is indoors in sight of an indoor receiver, or outdoors in sight of a strobe,
pressing the buttons in sequence performs a test. If the test is successful, a small green light
will flash on the indoor receiver, or the strobe will flash briefly. There will be no response at
all if the test fails. If the test fails, the user should contact the Security office as soon as
possible.
Every successful test is recorded in the Subscriber Database in the Central Console software
and optionally printed on the hardcopy printer. The Subscriber Database contains all of the
information relating to each subscriber, including the date and time of the most recent test
transmission. It is possible to search the Subscriber Database for individuals who have not
performed tests for a specified period of time.
Low battery reporting
When the transmitter is tested, a special “low battery” message is included in the
transmission to the Central Console if the transmitter’s battery is in need of replacing. Also,
the system will not give a visual or audible response during a test, indicating that the
transmitter requires service. Low battery alerts are logged at the Central Console.
Available models
There are two SE3 models available:
–User transmitter: This is the standard transmitter used by all system subscribers.
–Security transmitter: This is the same as the standard transmitter except the transmitter
does not emit an audible tone when activated. This transmitter is normally distributed to
Security personnel.

with the user’s picture, and his or her name, and any other necessary information.
Transmitting an alarm
There are three ways in which an alarm may be generated, depending on the features enabled
on the transmitter. The types of alarms are as follows:
–Manual duress alarm: An alarm can be initiated by pressing the large button on the
transmitter.
–Man-down alarm: The transmitter will transmit an alarm to the Central Console if it is
tipped 60° from upright.
–Lanyard pull: A cord connected to the pin inserted in the base of the transmitter can be
looped around a utility belt and if the pin is removed from the transmitter (such as when
the transmitter is pulled away from the belt), the transmitter will immediately go into
alarm.
Auto-tracking feature
During an alarm, the transmitter automatically resends the alarm signal every few seconds
constantly updating the Central Console of the user’s location.
Supervision tracking
With supervision tracking enabled, the transmitter will send a tracking signal to the Central
Console constantly updating the user’s location.
Testing
The test mode allows a user to test their transmitter anywhere in the protected area. When
the user is indoors, in sight of an indoor receiver, or outdoors, in sight of a strobe, pressing
the manual test button performs a test. If the test is successful, a small green light will flash

Description
The SE3401 Point Tracking Transmitter contains a unique code which is associated with an
asset at the time the Transmitter is assigned. When an alarm is generated, this code is sent to
the Central Console, which graphically displays the asset’s location on a map along with a
picture of the asset and any other necessary information.
Installation
The SE3401 can be configured to monitor magnetic or dry external contacts. When mounted
with an external magnet, the SE3401 is mounted on the asset and the magnet is mounted on
an opposite surface (such as a wall). When mounted with external contacts, the SE3401 can
be mounted anywhere on the asset and connects to the contact by two wires connected to
the terminals inside the Transmitter and an end-of-line resistor.
Transmitting an Alarm
Depending on the installed options, when an alarm is generated within approximately two
seconds, the sounders in any nearby Receivers could be activated as well as the Strobes and
Sirens connected to nearby Alert Units. The alarm signal is transmitted to the Receivers which
in turn relay the alarm signal to the Transponder and along to the Central Console. The Central
Console graphically displays the Transmitter’s location along with the asset’s description and
a picture of the asset. Also, once an alarm is initiated, the Transmitter commences its AutoTracking feature.
Auto Tracking Feature
Once an alarm has been initiated (such as when the Transmitter has been moved away from
the magnet) the Auto-Tracking feature will begin. The Transmitter will send a signal back to
the Central Console every few seconds updating its location for several minutes. To reset the
Transmitter after an alarm has been initiated, all device conditions (e.g., tamper, loop,
magnet) must be reset to normal.

2.7SEFD1 transmitter
Calls for Help Even When You CannotCalls for Help Even When You Cannot
The SEFD1 Fall Detector and Personal Help Button provides assistance that no other personal
Help Button can offer. The device alerts your emergency monitoring service automatically when
it detects a fall, even if you are unable to push the Help Button on the device.
The SEFD1 is designed to work in and immediately around your home or facility. The device
must be close enough to a receiver for a help signal to be received. The coverage area of the
device will vary from one location to another. It is important for you to know the effective
range of your device.
The SEFD1 is designed to detect falls that meet certain criteria. It may not detect every fall,
especially slight falls that are generally not disabling. The SEFD1 Fall Detector device may also
generate a fall alarm when you have not fallen. For example, if the device drops on the floor, it
may alert the monitoring center that you have fallen.
Operation
The SEFD1 device transmits three conditions:
–Push Button (Help Button)
–Fall
–Low Battery
2.8EA102 receiver
Features
–Receives Transmitter alarms and tests, and relays the information to the Transponder.
–Built-in self testing through Buddy Check feature.
–Indoor and outdoor security enclosures available.
–Indoor enclosure provides confirmation of successful Transmitter test. (Outdoor
enclosures use other type of signaling device, such as a Horn/Strobe.)
–Indoor Receivers provide local sounders in alarm events.
Description
The Receivers are located throughout the protected area, including building interiors.
Each Receiver contains a radio receiver to detect the transmissions from Transmitters, and a
microcomputer to decode and interpret the received test and alarm messages. In addition, the
microcomputer monitors tampering and other problems, and reports such conditions to the
Transponder.
Each Receiver contains an internal self-contained sounder. These sounders are optionally
activated if the Receiver has detected an alarm transmission.
Indoor Receivers are typically mounted on inside walls and are housed in small beige,
rectangular units. Indoor Receivers have one red and one green light. The green light is used
to indicate a successful test of a Transmitter; the red light is only illuminated during certain
system tests and during alarms.
Outdoor Receivers are contained in small weatherproof enclosures typically mounted on the
sides of buildings and on light posts. Outdoor Receivers do not have the visible red and green
LED’s. Outdoors, the strobe lights connected to the Alert Units flash to acknowledge a
successful test.
Function During an Alarm
In the event of an alarm, the Receivers detect an alarm signal from a Transmitter and send this
information to the Transponder. The Transponder forwards this information the Central
Console where, using the reported information from all the Receivers that detected the signal,
the location of the transmission is graphically displayed on the Alarm Map.
Buddy Check
In addition to its radio receiver, each Receiver also contains a transmitter functionally similar
to the hand held Transmitters. This transmitter can be commanded by the Central Console to
transmit a test message to other nearby Receivers. This Buddy Checking is performed
periodically to verify that the Receivers are functioning satisfactorily. Results of the Buddy
Check are compared with the results of earlier Buddy Checks, and any changes in a Receiver’s
sensitivity are reported to the Central Console where this information is stored in a system
database.
2.9EA500 transponder
Features
–Relays alarm and test signals from the Receiver to the Central Console.
–Can support a combined total of 64 Receivers and Alert Units.
–AC powered with battery backup for all Receivers.
–Can provide power to SE485 Interface and/or Spread Spectrum Radio.
Robert Bosch (SEA) Pte LtdTraining Manual2017.08 | V2.18.1.0 | DOC
20en | System components/specificationsSecurity Escort
–Available in a large or small indoor enclosure.
–Monitors Receivers and Alert Units 10 times per second for alarms, tests, tamper
notification, and power loss.
Description
The Transponder is a device controller for up to 64 devices -- any combination of Receivers
and Alert Units. Its primary function is to monitor the Receivers and Alert Units and report
conditions and events to the Central Console via either wire or ProxLink radios. It also
provides power output to certain devices.
Installation
The Transponder can be mounted in one of two different sized enclosures. It is always
mounted indoors. The devices are connected to the Transponder by means of eight four-wire
Multiplex Busses, two wires for power and two wires for data. Each bus is capable of
supporting up to eight devices. A Security Escort System supports up to 255 Transponders.
Configuration
Each Receiver and Alert Unit is identified to its Transponder by a Multiplex Address which is
set during system installation using a multi-position switch on the Receiver or Alert Unit circuit
board. Transponders communicate on the data bus with individual Multiplex devices by
issuing commands, which contain the Receiver or Alert Unit’s Multiplex Address.
Setup and Testing
Each Transponder and the devices connected to it are set up and can be tested remotely from
the Central Console. Also, each Transponder reports any problems, such as low battery,
immediately upon detecting them.
Function During an Alarm
When a Receiver or Alert Unit detects an alarm, it goes into an “Off Normal” state. To quickly
locate any devices which might be in the “Off Normal” state, the Transponder issues global
commands (which are interpreted simultaneously by all of its devices) approximately 10 times
per second. These global commands are followed by commands to specific devices to
determine the nature of the “Off Normal” condition and, in the case of an alarm (or test), to
obtain the Transmitter Identification Number, Transmitter battery condition, and received
signal strength. This information is then sent to the Central Console, by either wire or through
ProxLink radios, where it is used to graphically display the identity of the subscriber
transmitting the alarm and to determine the subscriber’s location.
2.10EA120 alert unit
Features
–Provides output for alarm annunciation through the Siren/Strobe or other third party
switched device.
–Provides output to Siren/Strobe to indicate a successful Transmitter test.
–Indoor and Outdoor enclosures available.
–AC powered with battery backup.
–Activated on command from the Central Station through the Transponder.
–Reports tampering, AC power loss, backup battery power to the Transponder, and output
status.
Description
An Alert Unit is a control module that communicates with the Transponder on the MUX Bus. In
most installations, it is used to activate Siren/Strobe units or other switched devices in the
event of an alarm. The Alert Unit also reports tampering, AC power loss, and backup battery
level to the Transponder.
Installation
The Alert Unit may be housed in either a metal indoor enclosure or an outdoor enclosure
(similar to the Outdoor Receiver enclosure), depending on the application. The Strobe/Siren
units are always mounted in outdoor locations.
Function
The Alert Unit has backup battery power in addition to AC power. The Alert Unit Driver
contains a microprocessor that communicates with the Transponder for Strobe and Siren
commands, status reports, and trouble indications. The troubles monitored are “Tamper”,
“Loss of AC Power”, and “Low Battery”.
Test Acknowledgment
In addition to the function of attracting attention in the event of an emergency, the Strobe unit
is used to acknowledge a successful test of a Transmitter. The Alert Unit can be configured to
cause a Siren to emit a short tone and the strobe to flash for a successful Transmitter test.
Function During an Alarm
In the event of an alarm, the Alert Unit receives a signal from the Transponder and begins
powering the Siren/Strobe (or other switched device). The Siren/Strobe will be active until
the alarm is restored at the Central Console.

22en | Equipment estimation, location accuracy and receiver locationSecurity Escort
3Equipment estimation, location accuracy and receiver
location
A Security Escort system installation consists of three major steps:
1.the pre-bid equipment estimation,
2.the pre-construction coverage verification survey, and
3.the post construction setup.
The Security Escort receivers work effectively in a wide variety of installations and can be
placed with confidence provided these installation requirements are met. Therefore, at the
pre-bid stage, it is acceptable to estimate the required equipment. To ensure proper coverage
after proposal acceptance, potential receiver locations can be verified using a standard
receiver in test mode or the portable test receiver before construction begins.
3.1Location accuracy
The Security Escort system provides quick response to a duress call. Its intent is to dispatch a
responding individual to an area without additional delay to their response to that duress call.
Figure3.1: System Block Diagram
The Security Escort system uses radio frequency (RF) for alarm transmissions. This is
significant because it prevents normal construction from blocking the signal and helps to
eliminate dead spots where the alarm could not be heard. The fact that RF energy passes
through normal construction prevents Security Escort from locating an alarm with 100%
certainty to a specific side of a wall. Alarms originating at or near building walls will typically
be indicated within 7.5 m (25 ft) of the actual location. However, there may be times when the
computed location may appear to be on the other side of the wall.
The Security Escort system was designed to provide a computed alarm location typically
within 7.5 m (25 ft) of the actual location when indoors, and a computed alarm location
typically within 15 m (50 ft) of the actual location outdoors. Any deviation from the following
installation guidelines will degrade the computed location accuracy. Therefore, to achieve
accuracy, the following installation guidelines must be adhered to.
Security EscortEquipment estimation, location accuracy and receiver location | en23
3.2Pre-bid equipment estimation
The pre-bid equipment estimation is performed prior to bidding the installation. At this point,
it must be determined what type of coverage is desired, and where the coverage will be
required. For example, the amount of equipment required for a full-coverage (indoor and
outdoor) system in a multi-building application is greater than an installation that requires
outdoor only coverage. The customer should be consulted, and the areas of most concern
should be given special consideration.
3.2.1Initial equipment estimate
Number of indoor receivers
To estimate the number of indoor receivers, first read Indoor receiver installation. Assume the
receivers are placed on a grid with a maximum spacing of 25 m (80 ft) between receivers for
standard construction. In multi-floor applications the receivers on each floor must be placed
directly above the receivers on the floor below (this is required for proper floor-to-floor
location).
For example, to determine the number of receivers required to protect a building of standard
construction of 60 m x 30 m (200 ft x 100 ft) and four floors:
1.To determine the number of receivers in each direction, divide each dimension of the
building by 25 m (80 ft), drop the remainder, and add 1. For example:
–60 m/25 m = 2.4, becomes 2, add 1 = 3
(200 ft/80 ft = 2.5, becomes 2, add 1 = 3)
–30 m/25 m =1.2, becomes 1, add 1 = 2
(100 ft/80 ft =1.25, becomes 1, add 1 = 2)
2.To determine the number of receivers required per floor, multiply the number of receivers
in one direction by the number of receivers in the other direction.
(3 x 2 = 6) 6 receivers per floor.
3.To determine the total number of receivers, multiply the number of receivers per floor by
the number of floors.
(6 x 4 = 24) 24 receivers for the building.

1 Receivers (6)
Robert Bosch (SEA) Pte LtdTraining Manual2017.08 | V2.18.1.0 | DOC
24en | Equipment estimation, location accuracy and receiver locationSecurity Escort
Each floor would require 6 receivers, resulting in a total of 24 receivers to protect this
building.
For the best location accuracy, consistent receiver spacing is important. Do not place
receivers significantly closer in one section of a building than another section.
Number of outdoor receivers
To estimate the number of receivers, first read Outdoor receiver installation. Assume a
maximum receiver spacing of 90 m (300 ft) between receivers, in both directions, for receivers
that are not within 30 m (100 ft) of a building with inside coverage. Receivers within 30 m
(100 ft) of a building should be spaced the same as receivers in the building (spacing the
outside receivers at a somewhat larger spacing is acceptable in most cases).
An outside area directly between two buildings with inside protection will need no additional
receivers if the buildings are 90 m (300 ft) or less apart. If the buildings are more than 90 m
(300 ft) apart the outside receivers should be evenly spaced between the buildings. Make sure
the standard 90 m (300 ft) spacing is not exceeded. For spacing outside adjacent to a covered
building, start the 90 m (300 ft) spacing at the building wall.
Allowance for special coverage requirements
For purposes of the bid, the number of receivers estimated above should be raised by 5% to
allow for special coverage considerations and RF problem areas.
Number of transponders
Assume one transponder per building for indoor installations. If wiring can be run from other
buildings or from outdoor receivers, they may be connected to one transponder. Never exceed
the total number of 64 devices (receivers and alert units) per transponder. All outside wiring
must be under ground, or in metal conduit.
Number of receivers and alert units per bus
For transponders, each bus can handle 8 receivers and alert units. However, it is a good idea
to leave some addresses available on each bus to allow for future expansion. For systems with
a high number of supervised transmitters, see Transponder wiring notes.

Bus wire
The multiplex bus for transponder should be wired with 4 conductor 18 gauge (1.2 mm) wire.
The wire should not be paired or shielded. In the United States this is the same as fire system
wire, except it should not be red.
Number of alert units
The number of alert units will be determined by each system’s requirements. In general,
enough alert units should be installed to be heard and seen from all outdoor locations of
protection. Remember that even in a silent system, alert units can be used outside to provide
test feedback. Horn/strobe units should be mounted in predictable locations to make them
easy to identify by subscribers. Alert units are not required indoors because the indoor
receiver provides alarm and test feedback. Each transponder will drive one siren and one
strobe if they are less than 15 m (50 ft) from the transponder.
It is a good idea for each protected parking lot to have a siren/strobe near it.
3.3Pre-construction coverage verification survey
The pre-construction coverage verification survey is performed after the bid is accepted and
before construction begins. It is done to determine the location of each receiver. Each receiver
location should be checked using a standard receiver in the test mode.
3.3.1Verify each potential receiver location
Using a receiver in “receiver spacing” mode
”Receiver spacing” mode is enabled with jumper P5 in place (jumper P4 removed) on a
receiver (see the EA102 Receiver Installation Instructions).
This mode is exactly the same as the “test” mode, except that only transmissions with an
adequate receive margin are sounded. This indicates the maximum acceptable spacing of
receivers. Use the following procedure to test the spacing of receivers:
1.Mount the first receiver.
2.Put jumpers P1, P2, P3, and P5 in place, and remove all other jumpers. Power the
receiver from a or 12 VDC source.
3.Take the second receiver and a transmitter a distance away from the first receiver.
4.Activate the transmitter.
5.If receiver 1 sounds the test beep, receiver 2 is within range. Repeat this test until
receiver 1 no longer sounds the test beeps. Move back to the last location where receiver
1 received the test beeps. This location marks the maximum spacing between receivers.
The distance between receivers should not exceed 25 m (80 ft) indoors and 90 m (300 ft)
outdoors. Mount receiver 2 at this location or closer to receiver 1.
Notice!
Do not use the “test” mode (jumper P4) to determine receiver spacing.

Using a transponder, receivers, and laptop computer to determine receiver location
Notice!
System software and an area map must be installed on a laptop computer to use this method.
A transponder with long multiplex wires connected to receivers can be used to see actual
alarm location before the receivers are placed. Place the receivers in the proposed locations
wired back to the transponder. Program the receivers with their locations in the TransponderDatabase. Using the maintenance transmitter and the maintenance alarm database, activate
alarm transmissions within the area surrounded by the temporarily placed receivers. Verify
that the location accuracy is acceptable at all points of concern. If not acceptable move the
receivers, update the receiver location in the Transponder Database, and retest. Do not test
outside of the last receiver in any direction, as this gives incorrect locations. Repeat this test
in all areas of different construction and concern at the site.
3.3.2Indoor receiver installation
–Indoor receivers must be mounted in a evenly spaced grid no more than 25 m (80 ft)
apart.
–Indoor receivers must be mounted 1.5 to 1.8 m (5 ft to 6 ft) above the floor. This is true
even if this is a single story building. Do not mount receivers above the ceiling or in roof
rafters.
–In multistory buildings, the receivers must be mounted directly above the receivers on the
floor below. The same number of receivers must be used on each floor level. If you meet
all of the indoor installation guidelines, you can expect the computed location to indicate
the correct floor about 95% of the time.
–Receivers must not be mounted within 30 cm (1 ft) of any metal object, including wire
mesh, metal foil, metal pipe and HVAC ducting in walls.
Security EscortEquipment estimation, location accuracy and receiver location | en27
–Take care that large metal objects do not shield a receiver from a protected area. For
example metal staircases, metal food serving lines, metal walls, lead lined walls, metal
roofs, wire mesh in walls, walk-in freezers and refrigerators.
For the best indoor and outdoor location or an indoor only system
–Mount the indoor receivers on the recommended 25 m (80 ft) grid, with the last row of
indoor receivers on the outside wall of the building. Do this even if the building is less
than 25 m (80 ft) wide or long.
–There should be a receiver at each outside corner of a building.
Handling two protected buildings sharing a common wall with floor levels that do not match
–Ask the customer which building has areas of greater concern and favor the
recommended mounting heights in that building.
–The recommended 25 m (80 ft) maximum indoor spacing grid should be maintained
throughout both buildings as if the wall in question was not there. Mounting heights only
for those receivers at or near (within 6 m [20 ft]) the wall in question should be affected.
Mounting heights for all other receivers in the buildings must follow the indoor
recommendation. Mark the recommended mounting height for receivers on the higher
floor level and also mark the recommended mounting height for receivers on the lower
floor level. Mount the receiver at its normal grid location midway between these two
heights, but not above the ceiling level of the lower floor.
3.3.3Outdoor receiver installation
–Outdoor receivers must be mounted in a evenly spaced grid no more than 90 m (300 ft)
apart.
–Outdoor receivers must be mounted 3 m (10 ft) above the ground.
–Receivers must not be mounted within 30 cm (1 ft) of any metal object, including fences,
metal walls and walls with wire mesh. If a receiver is mounted on a metal fence, that
fence should be grounded (not floating or insulated from ground) and the receiver should
be spaced 30 cm (1 ft) from the fence and 3 m (10 ft) above the ground.
–Take care that large metal objects do not shield a receiver from a protected area. For
example; metal fences, metal staircases, metal buildings, power transformers and metal
roofs.
–Receiver locations should be below building overhangs and eaves as these can shield the
areas below them.
–Receivers should have a clear line of sight of the protected area. Therefore, take care
where the ground is hilly or uneven, that there are no areas and low spots where several
receivers can’t hear the signal.
Transition areas between indoor and outdoor areas
–An outside area directly between two buildings with complete indoor protection will need
no additional receivers between the buildings, if they are 90 m (300 ft) or less apart.
–When protecting an outside area directly between two buildings with complete indoor
protection, and they are more than 90 m (300 ft) apart, place a row of outside receivers
evenly spaced between the buildings. Make sure the receiver row does not exceed the
standard 90 m (300 ft) spacing from the buildings. The spacing between receivers in that
row should be about the same as the spacing for the receivers in the buildings.
Robert Bosch (SEA) Pte LtdTraining Manual2017.08 | V2.18.1.0 | DOC
28en | Equipment estimation, location accuracy and receiver locationSecurity Escort
–Indoor receivers should be no more than 25 m (80 ft) apart and outdoor receivers should
be no more that 90 m (300 ft) apart. Both of these recommendations work well in their
respective areas. However, if a building is adjacent to an outdoor area, that building will
have a greater density of receivers and, therefore, has a tendency to pull the computed
location towards it. To counteract the building tendency to pull the location, consider the
following special cases:
–If the outdoor area adjacent to the building is wide open and the customer is not
concerned about reduced location accuracy in this area, then nothing special needs
to be done. Follow the normal indoor and outdoor recommendations.
–The building is near the boundary of the protected area, with or without a fence at
the boundary. The receivers in the building should be placed at the recommended 25
m (80 ft) spacing. The receivers at the boundary of the protected area near the
building should be spaced about the same as those in the building, approximating
the same grid as used in the building.
–The building is adjacent to a large protected outdoor area that extends for more than
90 m (300 ft) from the building. The receivers in the building should be placed at the
recommended 25 m (80 ft) spacing. The receivers in the large protected outdoor
area should be placed on the normal 90 m (300 ft) grid except for the first row of
receivers adjacent to the building. This first row of outdoor receivers in the transition
area should “split the difference” between the indoor and outdoor spacing at about
60 m (200 ft).
Boundary areas at the outer edge of the protected area
The system cannot locate an alarm past the last receiver at the boundary of the protected
area. Therefore, the last row of receivers must be at or past the end of the protected area.
After the site survey (and special pre-construction verifications) has been completed, the
wiring can be run between the proposed locations of the system components and the Central
Console. See specific installation instructions accompanying each component for wiring
details.
