SE3 Subscriber Transmitter

Features

• Alerts Central Console of user’s name and location immediately on alarm.

• Post-alarm tracking, alarm map recall, and more.

• Allows user to test from anywhere within the protected area.

• Internal antenna.

• Four-year battery life, field replaceable.

• Key-chain attachment.

• Low battery indication at Central Console.

• Optional silent alarm.

Description

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 Auto-Tracking 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.

graphically displays the user’s location on a map along 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 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. When
the Transmitter is tested, a special “low battery” message is included in the transmission to Central Console if the
Transmitter’s battery is in need of replacing. 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.

• Internal antenna.

• Two-year battery life.

• Can be mounted virtually anywhere on virtually anything.

• Low battery indication at Central Console.

• Includes mounting plate.

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 Auto-Tracking
feature.

Auto Tracking Feature

Once an alarm has been initiated (such as when the Transmitter has been moved away from the magnet) the Auto­Tracking 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.

Supervision Feature

The SE3401 Point Tracking Transmitter can also be configured to transmit periodically when there is no other activity
to report its status and location to the Central Console.

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. These low battery alerts are logged at the Central
Console.

EA102 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.

Security Escort Training

Page 15 of 142

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.

Component Descriptions – EA500 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.

• 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.

Security Escort Training

Page 16 of 142

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.

Component Descriptions – EA120 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.

Equipment Estimation, Location Accuracy and Receiver
Location

General

A Security Escort system installation consists of three major steps. The pre-bid equipment estimation, the pre­construction coverage verification survey, and 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.

Location Accuracy

The Security Escort system is intended to provide quick response to a duress call. Its intent is to dispatch a
responding individual to an area that will not add additional delay to their response to that duress call.

The Security Escort system uses radio frequency (RF) for alarm transmissions. This is a significant positive
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 also 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 25 ft. (7.5 m) of the actual location, however there may be times
when the computed location may appear to be on the other side of the wall.

Security Escort system was designed to provide a computed alarm location typically within 25 ft. (7.5 m) of the
actual location when indoors and a computed alarm location typically within 50 ft. (15 m) 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:

Pre-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 will be

Figure 1a: System Block Diagram

Security Escort Training

Page 18 of 142

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.

Initial Equipment Estimate
Number of Indoor Receivers

To estimate the number of indoor Receivers, assume the receivers will be placed on a grid with a maximum
spacing of 80 ft. (25 m) 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 (200 ft.) by 30 m (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.) and drop the remainder and add 1.

(60 m/25 m = 2.4 becomes 2 add 1 = 3 and 30 m/25 m =1.2 becomes 1 add 1 = 2) or
(200 ft./80 ft. = 2.5 becomes 2 add 1 = 3 and 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.

60 m

(200 ft.)

25 m

(80 ft.)

25 m

(80 ft.)

30 m

(100 ft.)

Receivers (6)

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.

Security Escort Training

Page 19 of 142

Number of Outdoor Receivers

To estimate the number of Receivers, 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 at the spacing of 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 placed 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 but 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 Receiver and Alert Units Per Multiplex Bus

Although each bus can handle 8 Receivers and Alert Units it is a good idea to leave some addresses available
on each bus to allow for future expansion.

Multiplex Bus Wire

The multiplex bus 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.

Security Escort Training

Page 20 of 142

Pre-Construction Coverage Verification Survey

The pre-construction coverage verification survey is performed after the bid has been 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.

Verify Each Potential Receiver Location
Using a Standard Receiver in Receiver Spacing Mode

Receiver Spacing Mode is enabled with Jumper P5 in place (Jumper P4 removed) on a standard Receiver (see
the EA102 Receiver Installation Instructions). This mode is exactly the same as the Test Mode above, 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. Put jumpers P1, P2, P3, and P5 in place, remove all other jumpers. Power the

Receiver from a 9 or 12 VDC source.

2) Take the second Receiver and a Transmitter a distance away from the first Receiver.

3) Activate the Transmitter.

4) 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 24 m (80
ft.) indoors and 91 m (300 ft.) outdoors. Mount Receiver 2 at this location or closer to Receiver 1.

NOTE: Do not use the Test Mode (Jumper P4) to determine Receiver spacing.

NOTE: System Software and Area Map must be installed on Laptop Computer to use this method.

A standard Transponder with long multiplex wires connected to standard 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 Transponder database. 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 will give incorrect locations. Repeat this test in all areas
of different construction and concern at the site.

Indoor Receiver Installation

• Indoor receivers must be mounted in a evenly spaced grid no more than 80 ft. apart.

• Indoor receivers must be mounted 1.5 to 1.8 m (5 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.

• 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 at 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 of the outside corners of a building.

How to handle 2 protected buildings that share a common wall and have floor levels
that don’t match

• Ask the customer which building has areas of greater concern and favor the recommended mounting heights
in that building.

• The recommended 80 ft. (25 m) maximum indoor spacing grid should be maintained throughout both buildings
as if that 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.

Outdoor 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.

Security Escort Training

Page 22 of 142

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.

• Indoor receivers should be no more than 25 m (80 ft.) apart and outdoor receivers should be no more 90 m
(300 ft.) apart. Both of these recommendations work well in their respective areas. However this means that
where a building is adjacent to an outdoor area, that the building will have a greater density of receivers and
therefore will have 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.
