Chapter 1: Introduction
About this manual
This manual provides full details of how to operate and administer an i-on
alarm system as a user. The manual describes:
The user types.
The meaning of part-setting and partitioned modes.
Detailed information about how to perform functions such as setting
and unsetting the system.
How to manage alarms.
The options available from the user menu to carry out tasks such as
omitting zones, adding users and viewing the log.
Other publications
If you are new to i-on alarm systems, you should read one of the following
guides first:
i-on Compact User Guide.
i-on Series User Guide (for i-on30R+, i-on40H+, i-onG2SM and
i-onG3MM).
These provide an introduction to the key concepts and components of the
alarm system, and how to carry out the most common day-to-day tasks.
Additional user guides are also available for other items, such as the KEY-
RAS radio keypad. Your installer will be able to tell you which guides are
available for the equipment installed at your site.
Other publications are available to installers −these describe topics such
as system installation, maintenance and installer options.

Introduction

About Users
A user is a person who is able to enter an access code at a keypad to
perform an action such as to:
Set or unset the system.
Acknowledge and stop alarms.
Raise duress alarms.
Gain access to the user menu to carry out tasks such as to omit
zones, view the log, test the system and switch outputs on or off. For a
full list of available user options, please refer to the User Menu Map on
page 25.
When the system is new, there is only one user: the default master user,
who has full access to perform any action that a user is able to do and
access all user options. The master user can add new users, and while
doing so, specify the user's type, which determines the actions the user can
carry out. The user types are described in the next section.
User types
Note: Some user types are available only if the system is configured as a
partitioned (not part-setting) system. Please refer to page 5 for a
description of part-setting and partitioned modes.
The available user types are as follows:
Master user –This user is able to carry out all user actions. A master
user can, for example, set or unset the system and access all options
in the user menus, including the ability to add or delete other users.
A master user can edit any user's name, and for all but other master
users, edit a user's type and partitions (if applicable).
In a partitioned system, all master users always belong to all partitions.
There is always (at least) one master user (User 001), which cannot
be deleted by any user.
Admin (partitioned system only) –This user is similar to a master
user, but is limited to one or more partitions.
Admin users can set or unset the system and have access to most
options in the user menu (see User Menu Map on page 25). They can
add, delete or edit other users (including admin users) belonging to the
same partition(s), but cannot add, edit or delete master users. Admin

Introduction
Page 3
users can assign other users to any of the partitions that the admin
user belongs to.
Normal user –A normal user can set and unset the system, but has
access to a limited number of user options. A normal user can, for
example, omit zones, change their own access code, add their own
proximity tag, view the log and operate outputs, but cannot add or
delete users.
In a partitioned system, a normal user is assigned to one or more
partitions, which are the only parts of the system that they can set and
unset.
Partition user (partitioned system only) –A partition user is similar to
a normal user, but has the added restriction that they must set and
unset their allocated partitions from keypads that are also assigned to
those partitions.
Duress Code (not available for i-on Compact) –A duress code user
can set or unset the system, but whenever the access code is used,
the control unit can, for example, notify the Alarm Receiving Centre
(ARC).
A duress code has no access to the user menu and cannot have a
remote control or proximity reader tag.
Note: The Installer must program your system to provide this feature,
and you must agree with your alarm installer and the ARC what action
the ARC should take on receiving a duress message.
Guard (not available for i-on Compact) –A guard user can only unset
the system when it is in alarm and set it again. A guard user has no
access to the user menu.
In a partitioned system, a guard user can be allocated to one or more
partitions, which are the only parts of the system that they can set and
unset.
Set Only (not available for i-on Compact) –This type of user can set
the system, but not unset it. A set-only user has no access to the user
menu.
In a partitioned system, a set-only user can be allocated to one or
more partitions, which are the only parts of the system that the user
can set.
Shunt Code (not available for i-on Compact) –This type of user code
is used only for activating and deactivating shunt groups (see page

Introduction
Page 4
29). When the user's access code or proximity tag is used, all zones in
the shunt group assigned to this user are shunted.
Easy Set (not available for i-on Compact) –This type of user unsets or
sets the whole system (for a part-setting system) or all partitions
allocated to the user (in a partitioned system). When the user's access
code, proximity tag or remote control is used:
In a partitioned system, if any partition assigned to the user is
currently set, all are unset. In a part-setting system, if the system
is part set, the whole system is unset.
In a partitioned system, if all partitions assigned to the user are
currently unset, all are set (even if there are alerts present). No
partitions are set if any has an active zone. In a part-setting
system, if the whole system unset, the whole system is set.
BMS –This is designed to give third-party systems permission to
perform actions that would normally be performed by a normal user,
such as setting and unsetting. A remote password is automatically
generated and displayed when you create this user, which the third-
party system requires.
Level-4 –This type of user can be created only by the installer, and is
able to update the firmware and language files at the control unit using
the web interface. There can be only one level-4 user.
The level-4 user cannot set or unset the system, and is able to use the
user menu only to change their own name and access code (to access
the web interface).
User access codes
To set or unset the system or access the user menu, a user must identify
themselves either by entering a valid access code at the keypad or by
presenting a proximity tag. Access codes and proximity tags are unique to
each user and can be used interchangeably at any time. Each access code
is either 4 or 6 digits, depending on how the system is configured.
Users can also use a remote control to set or unset the system, or to
operate outputs (depending on how the system is configured).
The access code of the first master user is defined by the installer during
installation. It is recommended that you change this user code as soon
as possible after system installation (see page 33).

Introduction
Page 5
Code lockouts
If a user has problems remembering their code, or has acquired an
unrecognised proximity tag, they may try keying in their code or presenting
the tag several times. If this happens four times in a row, the control unit
locks all keypads for 90 seconds and starts an "Excess Keys" tamper
alarm. If configured, the control unit also sends the event to the Alarms
Receiving Centre (ARC).
Once 90 seconds has elapsed, the keypads allow users to try again. If an
incorrect code or tag is used again, the keypad locks them out for a further
90 seconds, and so on.
Installer access
The installer has their own access code to access the installer menu
options for system configuration. There is only one installer access code. It
cannot be used to set or unset the system or to access the user options.
Note: The installer may be able to call into your control unit and program it
remotely (e.g. using the web interface). Depending on how your installer
has programmed the system, you may receive a phone call from the
installer to request access.
About part-setting and partitioned modes
Depending on your requirements, your system may have been configured
by the installer as a part-setting system or a partitioned system. These two
modes are explained next.
Part-setting mode
In part-setting mode, the control unit can set in one of four ways: either full
set or one of three part sets (part set B, C or D). Each zone can belong to
one or more part sets.
When the system is full set, the control unit sets all zones, irrespective of
the part set they belong to.
When the system is part set, the control unit sets only those zones that
belong to the part set you have chosen to set. The installer defines which
zones are in each part set. A part set may, for example, set all areas of the
building except the delivery area, which would allow people to occupy the
delivery area while the main part of the building is protected.
In a part-setting system, the system responds to just one keypad at a time.

Introduction
Page 6
Partitioned mode
Partitioned mode is useful if the system is installed at a site where it is
necessary for different groups of users to have independent control to set
and unset different areas of the building, such as certain offices in a
building used by several companies. The maximum number of partitions is
dependent on the type of control unit you are using.
The installer can allocate one or more zones to each partition, and users
can set and unset each partition completely independently of all the others.
Individual users can be given access to one or more partitions. If a user
has no access to a partition, he or she cannot set or unset that partition. In
effect, partitions allow the system to be split into separate alarm systems.
A zone is armed only when ALL of the partitions that it belongs to are set. If
you unset any of the partitions that a zone belongs to, the control unit will
unset that zone. This allows, for example, the system to include areas such
as lobbies that are shared by users belonging to different companies.
In addition, each partition can have a full-set level and up to three part-set
levels. Users can choose whether to set a partition to which they have
access at full or a part-set level. When the user chooses a part-set level, all
zones that the installer has assigned the appropriate "Part Set" attribute are
set, and the others remain unset.
For partitioned systems, you can use more than one keypad at the same
time, provided that they are in separate partitions. Within each partition, the
control unit responds to just one keypad at a time.
The installer can allocate keypads, sirens, sounders or outputs to any of
the partitions.

Chapter 2: Setting and Unsetting
Introduction
Readying the system to start an alarm when someone moves into a
protected area is called “setting” the system. Disarming the system so that
people can move freely is called “unsetting” the system.
You can set and unset your system using a variety of different methods,
depending on how the installer has configured your system. This chapter
explains typical methods used.
Note: The control unit can monitor some detectors continuously,
irrespective of whether the system is set or unset. For example:
Fire and smoke detectors, flood sensors, Hold Up Alarm buttons or
emergency exits.
Monitors for machinery (for example freezers) or other type of
“technical alarm”.
Using a keypad to set or unset the system
This section explains how to set and unset your system from any keypad
that has a display (including the keypad built into an i-on Compact control
unit). If you are using a radio keypad that has no display, please refer to
page 16 (i-RK01) or to page 17 (KEY-RAS).
Note: Please refer to the User Guide if you need an overview of the
purpose of the keypad keys.
Setting the system
1. Make sure the display shows the standby screen; for example:


2. Enter your access code or present your proximity tag to the keypad. If
you enter your access code, the display shows a “*” for each digit:

Note: Please refer to page 5 for details of part sets.
Full Set All (partitioned system only)
To set all partitions fully. This is available only if all
partitions are currently unset.
Partitions (partitioned system only)
To choose the partition(s) to set, and whether to full set or
part set those partitions.
Note: Please refer to page 5 for details of partitions.
4. If you selected Partitions:
a) The bottom line shows the name of the first partition to which
you have access and its current state (U = unset, S = full set,
PB/C/D = part set B/C/D is set):
↕

“U>S” = change unset to full set
“S>U” = change set to unset
“PB/C/D>U” = change part set B/C/D to unset
Note: If a partition is full set, you cannot change it to part set or
vice versa; you must unset the partition first.

Note: A zone is armed only when ALL of the partitions that it
belongs to are set.
d) Repeat steps b) and c) as required.
e) Press .
5. If you see a fault warning such as:


a) Press to override the warning and continue setting (if your
installer has allowed this).
b) Contact your installer for assistance.
You may see a setting fault (such as an active zone) that prevents you
from setting the system. Normally, the system can set only when
zones (other than those in the entry/exit route) are inactive.
6. You will hear a continuous exit tone (unless the system is configured
for silent or instant setting).
If you have the final exit door open, or you trigger one of the detectors
on your entry/exit route, the keypad gives an interrupted setting tone
(this is normal).
The system sets when one of the following occurs, depending on how
the system is configured:
Immediately (instant set).
After a specified period of time. You need to make sure you exit
the premises before the exit timer expires. The bottom line of the
display shows the remaining time:


When you have exited the premises and either pressed an exit-
terminate button, closed the final door or operated a lock. The
bottom line of the display shows which of these methods is being
used. (Exit terminate and lock set are not available for i-on
Compact.)
Note: You can press either the or key to stop the system setting before
it has set. (The key is not available for i-on Compact.)

How do I know that the system is set?
When the system sets the keypad briefly shows:


After a short period, the standby screen is displayed. For example:


In a part-setting system, one of the four ABCD keys (or one of the set/unset
LEDs on a i-KP01) may glow to show which part of the system is set
(Figure 1), unless disabled by the installer to meet appropriate standards.
Figure 1. Keypad LED positions to indicate set/unset status
In addition, the installer may have configured the system to flash the strobe
light briefly on the external siren/strobe unit when the system sets.
If the system does not set
If the system does not set, check the display to see if any zone is active.
Normally, the system can set only when zones (other than those in the
entry/exit route) are inactive. If there is more than one zone active, the
display changes every three seconds to show each zone in turn.
Quick-setting the system
Your installer may have enabled quick-setting, which removes the need to
use an access code or proximity tag to start setting.
Note: To make the system comply with certain regulations, the installer
may not be allowed to provide this facility.

D –To set part set D (part-setting system) or to set partition 4.
2. You will hear a continuous exit tone (unless the system is configured
for silent or instant setting). The system sets as described in step 6 on
page 9.
Unsetting the system
1. Enter through the entry route designated by the installer (this is
usually the same as you used to leave the premises). Do not stray
from this route –you may cause an alarm.
2. Depending on how the system is configured, you may hear an entry
tone. If you hear the tone, go directly to the keypad, since you will
have limited time to unset the system before it generates an alarm.
3. Enter your access code or present your proximity tag to the keypad. If
you enter your access code, the display shows a “*” for each digit:

a) Press to acknowledge the warning.
b) Contact your installer for assistance.
Using a two-way keyfob-style remote control
The two-way remote control (Figure 2) can be used to set and unset the
system, query the current set/unset status of the system or operate a User-
Defined output. Each remote control has a unique electronic identity and is
assigned (page 31) to a specific user.
The remote control is designed to provide feedback about the current
status of the system (if enabled by the installer). When you operate the
buttons, the control unit sends back signals that light up one or more LEDs
on the fob. These show whether your system has set, or if there has been
an alarm while you have been away.
Figure 2. Two-way remote control buttons
In a partitioned system, the remote control can be used for only one
partition.

The installer can use a 2W Set Instant option to choose whether the remote
control should set instantly or follow the configured exit mode (such as a
timed set).
Operating the buttons
To ensure that the remote control does not accidentally operate while it is
in your pocket, the buttons are deliberately slow to respond to pressure.
You must hold down the button you intend to press for at least three
seconds to activate its function.
See page 52 for details of programming the * button.
Setting from a two-way remote control
1. Make sure the system is in standby.
2. Press and hold the Set or Part Set button, as required. The Set or Part
Set LED flashes red three times.
If there is a fault (for example a zone is active), all four LEDs glow red
for three seconds.
3. You will hear a continuous exit tone (unless the system is configured
for silent or instant setting). The system sets as described in step 6 on
page 9.
4. The Set or Part Set LED glows green for three seconds. This is your
confirmation that the control unit has set the system.
Unsetting from a two-way remote control
Note: The ability for remote controls to unset the system can be disabled
(see page 56).
To unset the system:
1. Enter through the entry route designated by the installer.
2. Depending on how the system is configured, you may hear an entry
tone. If you hear the tone, you will have limited time to unset the
system before it generates an alarm.
3. Press and hold the Unset button. The Unset LED flashes red three
times.
4. The Unset LED glows green for three seconds. This is your
confirmation that the control unit has unset the system.

Querying the set/unset status from a two-way remote
control
1. Press and hold the Query button. The Query LED flashes red three
times.
2. The Full Set, Part Set or Unset LED glows to show the current status
of the system.
Starting a Hold Up Alarm (HUA) from a two-way remote
control
A two-way remote control can be used to start a Hold Up Alarm if enabled
by an installer and in the user menu (see page 56).
Note: Enabling this feature means that the system no longer complies with
BS8243 or DD243.
To start a HUA from a two-way remote control:
1. Press and hold any two diagonally opposite buttons at the same time.
All four LEDs flash red three times.
2. The control unit starts a hold up alarm and, if applicable, sends the
alarms to the Alarms Receiving Centre (ARC).
3. All four LEDs glow green for three seconds. This is your confirmation
that the control unit has generated the alarm.
Using a one-way remote control
The one-way remote control has four buttons and a small LED that glows
when it transmits a signal (see Figure 3). The buttons can be programmed
as required (see page 52), but by default, buttons are used to set or unset
the system.
Note that to prevent accidental operation the user must hold a button down
for at least two seconds to ensure a transmission.

5. Transmit LED.
Figure 3. One-way remote control buttons
Each remote control has a unique electronic identity. You can assign (see
page 31) only one remote control to each user.
Setting from a one-way remote control
1. Make sure the system is in standby.
2. Press the required button on the remote control. For example, Full Set
(A).
In a partitioned system, the default action for key A is to full set all of
the user's partitions. Keys can be configured to part set specified
partitions, if required.
3. You will hear a continuous exit tone (unless the system is configured
for silent or instant setting). The system sets as described in step 6 on
page 9.
If the system will not set
If one of the zones is active when you try to set the system, you will not
hear the exit warning tone. Instead, you will hear a single beep.
Try pressing A again on your remote control. If set up by the installer, the
system will omit the active detector and set. If the system does not set, you
will need to go to a keypad and investigate why the system will not set.

Unsetting from a one-way remote control
Note: The ability for remote controls to unset the system can be disabled
(see page 56).
1. Enter through the entry route designated by the installer.
2. Depending on how the system is configured, you may hear an entry
tone. If you hear the tone, you will have limited time to unset the
system before it generates an alarm.
3. Press on your remote control.
Using a one-way i-RK01 radio keypad
A one-way keypad (Figure 4) does not have a display and can only transmit
to the control unit (it cannot receive information back from the control unit).
Figure 4. One-way radio keypad
The keypad cannot show the status of the system. The left-hand “Transmit”
LED glows only to show that the keypad is sending a command to the
control unit.
Setting from an i-RK01 radio keypad
1. Make sure the system is in standby.
2. Enter a valid access code or present your proximity tag to the keypad.
3. Press (these are the default actions):
A –To set the system fully (part-setting system) or to set partition 1.
B –To set part set B (part-setting system) or to set partition 2.
