1 About This Manual
1.1 Introduction
This manual contains all the information required to operate the LoopSense Fire Alarm Control
Panel (FACP). The first step in becoming a proficient operator is to be familiar with and understand
the “Menu Structure” and the keys used to navigate through it. Once this concept along with the
screen prompts that are displayed during the navigation process are understood the user will find the
operation of the LoopSense Fire Alarm Control Panel (FACP) a simple task.
2 Introduction
2.1 System Overview
The purpose of the LoopSense Fire Alarm Control Panel (FACP) is to monitor changes in inputs,
report those changes and update selected outputs as programmed.
The FACP processes changes in inputs such as fire, fault, pre-alarm, emergency, security, user,
transparent and system and has a built-in menu structure to view its status, perform operational
tests, and modify the panel’s configuration and programming.
The LoopSense FACP is compliant with EN54-2 and EN54-4.
In addition to the mandatory requirements of EN54-2 the LoopSense meets the following optional
features with requirements:
7.8 Output to fire alarm devices
7.9 Control of fire alarm routing equipment
7.9.1 Output to fire alarm routing equipment
7.9.2 Alarm Confirmation input from fire alarm routing equipment
7.11 Delays to outputs
7.12 Dependencies on more than one alarm signal Type A, B and C
8.3 Fault signals from points
8.9 Output to fault warning routing equipment
9.5 Disablement of each addressable points
10 Test condition

3.1 Levels of Access
The FACP supports three levels of access.
Access Level 1 (Untrained User):
The FACP is in Access Level 1 by default.
Only the OVERRIDE, PREVIOUS, NEXT, SILENCE BUZZER and LAMP TEST controls are active.
Access Level 2 (Authorised User):
To enter Access Level 2 the user has to enter a password using the alpha numeric keys. The
password entry screen will be presented if any higher access level key is pressed. Alternatively
turning the Keyswitch to the ON position will force the panel into access level 2. The user is able to
navigate through the menu system in access level 2 however the ENTER PASSWORD menu item
will be displayed in place of the PROGRAMMING and SETUP menus.
Note: PROGRAMMING and SETUP menus are not accessible during a Fire condition
If ENTER PASSWORD is selected, the password entry screen will be presented allowing the user to
enter the access level 3 password. The user is able to enter the password when the password
screen is presented.
The access level 1 controls are active as well as SILENCE RESOUND, RESET, EVACUATE and
MENU ENTER controls. All menu items are active apart from the programming menu.
Access Level 3 (Authorised Service Technician/Engineer):
All access level 1 and 2 controls, PROGRAMMING, SETUP menus and individual sounder output
disable options are active.
If ENTER PASSWORD is selected, the password entry screen will be presented allowing the user to
enter the access level 3 passwords.

Page 3
LOOPSENSE EN54 USER MANUAL
3.1.1 Passwords
The FACP will support 99 user programmable passwords. Each password includes an access level
which can be either 2 or 3 corresponding to the access levels and a unique ID which ranges from 1
to 99. There is also a facility in the access level 3 SETUP menu to add, edit or delete passwords.
Note: Onsite programming only allows for the editing of ID1 and ID2 all other ID’s need to be
set using the LoopMaster configuration tool
All passwords are a 4 digit numeric entry and the system default passwords are as follows:
ID
Password
Access Level
1
3333
3
2
User
Defined
User Defined
Password Conditions
1. All password IDs that have not been assigned a password are set to access level 1 to
prevent false entries.
2. The entering of a password will be logged using the ID.
3. If no key is pressed for 5 minutes the access level will timeout to the default access level
being 2 or 1 depending on the key-switch position.
4. The access level timeout and key-switch operations will also be logged.
5. The intervals between key presses when entering the password must not exceed 30
seconds otherwise the password entry screen will timeout returning the panel to the default
access level.
6. The FACP can also be forced to the default access level by pressing the CANCEL key 4
times while default screen is displayed.
3.1.2 Misplaced Password
In the situation, where access to the panel is required, and the passwords are not available, there is
a facility for the appropriate service personnel to gain access to the panel.
The procedure is as follows:
1. The password “
#
, , , , ,
#
” is entered.
2. The panel responds by displaying a unique 10 digit key
3. Contact the local Ampac Service Centre and they will issue a temporary password
4. The temporary password is entered, and access is gained to the panel. The operator can
now access the password menu and set the passwords up as appropriate for the installation
The temporary password will be deleted, the next time a password is successfully entered into the

LOOPSENSE EN54 USER MANUAL
4.2 Fire Condition
If an input or device is activated and it is configured to generate a fire condition the FACP responds
to the fire as follows:
Common FIRE LED will turn on steady
Assigned zone fire LED will illuminate
Panel buzzer will sound continuously
Fire condition to be reported to the LCD (time ordered buffer 100 entries deep)
The fire event will be logged and printed, where a printer is fitted.
The panel fire output will activate
All outputs configured to operate under a fire condition will operate
The fire condition will be displayed on the LCD in the following format:
Zone with active Fire condition
The LCD displays the fire status screen and indicates the most recent zone in Fire by way of the

are viewable via the Display menu when fires are present.
“CONTROL*” Indicates that the control menu hotkey is available; pressing the “*” key on the numeric
keypad will allow direct entry into the control menu for the current point being displayed. This
requires level 2 access.
The user can perform the following actions in response to a fire:
The SILENCE/RESOUND key is used to silence any silence-able outputs that have been
activated in response to the fire condition. The ALARMS LED will be illuminate to indicate
that the sounders have been silenced and resound is available. The operation of the
SILENCE key will be logged. (This operation is only available at access level 2)
The OVERRIDE key can be used to override any delays to outputs (EN54-2:1997, clause
7.11). (This operation is available at access level 1)
The EVACUATE key can be pressed to turn all alarm devices.
The RESET key can be used to reset the fire condition. All outputs activated in response to
the fire will deactivate and the panel will revert to the normal condition providing there are no
other abnormal conditions present. (This operation is only available at access level 2)
The FACP also displays fires in Device mode. Pressing the “DEVICE►” forward button allows the
panel to display all the devices or inputs on the system that are in fire.

Use the ▲(up) (down) arrows to cycle through the inputs and devices that are in fire.
Device Alarm LED activation
Due to the limited current available from the analogue loop, the number of alarm LED’s allowed to be
illuminated simultaneously is limited to the first 10 devices in fire on each loop; after this limit is
reached any new devices in fire will not have its alarm LED illuminated until the original fires have
been cleared on that loop.

FAULT XXX OF XXX ◄DEVICE
Faults originating from sounders, outputs and un-zoned modules on loops, add-ons or the panel
main termination board shall be displayed individually as shown here.
Pressing the “DEVICE►” forward button will allow the panel to display all the individual inputs,
outputs and modules in fault.
Selecting “CONTROL*” will allow direct entry into the control menu for the current point or zone
being displayed (This operation is only available at access level 2).
4.3.1 System Fault Condition
(EN54.2:1997: 8.5, 13.4, 13.6, 13.7a)
The System Fault condition is activated if the FACP fails to provide mandatory functions. When a
system fault condition occurs, the panel buzzer, System Fault and General Fault indicators shall be
activated.
Mandatory functions failures include:
Critical hardware failure on Main Termination Board (MTB) – The system fault condition is
driven by hardware for this failure and can be cleared by hardware reset or power cycle of
the MTB if the hardware is not damaged.
Reset of the CPU on the MTB while the MTB maintains power – The panel shall re-initialise
if possible and the system fault condition shall be driven by software. In this case the fault
buzzer is silence-able at access level 1 or higher by using the SILENCE BUZZER control
and the system fault can be cleared by activating the RESET control at access level 2 or
higher. If the RESET control is activated at access level 1, the user shall be prompted to
enter a password; successful entry of an access level 2 or 3 password shall complete the
action.
Loss of communications with the Front Panel (FP) – The system fault condition shall be
hardware driven on the FP via the software in MTB and can be cleared by hardware reset or
power cycle of the FP if it is not damaged. The system fault condition is not resettable or
silence-able whilst the condition is driven by hardware. Upon successful reset of the FP, the
system fault condition shall remain latched and shall be driven by software. In this case the
condition is silence-able at Access level 1 by using the SILENCE BUZZER control and reset-
able at access level 2 or higher by using the RESET control.
Memory corruption (checked hourly) – The system fault condition shall be driven by
software. The panel shall be forced to diagnostics mode and all outputs shall be switched
off. The system fault buzzer may be silenced in this instance by using the SILENCE
BUZZER control access level 1 or higher and cleared by activating the RESET control at
access level 2 or higher.

Exception due to software failure in MTB – The system fault condition
shall be hardware driven via software when panel reboots and can be
silenced and cleared by pressing the STAR ‘*’ key on the FP provided the key-switch is in
the access level 2 position. The exception codes shall be presented on the LCD for service
support and the system shall remain in boot mode until resolved.
The following screen shall be presented if the system fault condition is driven by software for
mandatory functions failures 2, 3 and 4 above:
SYSTEM FAULT: <fault status>
PRESS <RESET> TO CLEAR
Fault statuses include:
“REBOOT DETECTED”
“MEMORY CORRUPTION”
“FRONT PANEL FAIL”
If the system is forced into diagnostics mode upon a memory corruption (mandatory functions failure
4 above) and the access level 2 keyswitch is active, the above screen shall be displayed as shown.
If the access level 2 keyswitch is off when this occurs, the bottom line screen shall read “ACTIVATE
KEY-SWITCH TO ALLOW RESET” in place of “PRESS <RESET> TO CLEAR”.
If the panel is forced into boot mode upon a software exception (mandatory functions failure 5
above), a screen such as the following shall be presented
!EXCEPTION! – PRESS * TO SILENCE
SR = 0x200000DF PC = 0x00437283 # = 0x00
BOOT VER: 1.01.0
Note: The silence feature is only available if the access level 2 keyswitch is active
In the event of a software exception these numbers should be recorded and reported to a customer
support representative.
Note: Sections 5.4 to 5.8 contain examples of device mode screens. Zone mode screens will
display the Zone mode descriptor. See section 5.3 for example.

5 Test Functions
The FACP provides a set of diagnostic test functions that can be run on various inputs & outputs
(like loops, loop devices, LED indicators, LCD display, Sounders etc) to verify whether they operate
as they are intended.
The diagnostic test functions are;
Loop test
Lamp test
Walk test
Device Locator
5.1 Loop Test
Access level 2
Loop Test is available via the Menu - - Control - - Panel - - Loop. - - Test.
Invoking the Loop Test will drive the loop firstly from side A followed by side B and count all detected
devices on each side of the loop. These counts will be displayed upon completion of the test
prompting the user to press CANCEL to end.
The loop test also monitors for
Over current and short circuit in single-ended mode
Over current, short circuit and open circuit conditions in redundant mode.
If there were any latching loop faults prior to commencement of the test these will be re-tested and
cleared if no longer present.
Once the Loop Test is complete the loop is re-initialised.
5.2 Lamp Test
Access level 1 or 2
The Lamp Test is initiated by pressing and holding the LAMP TEST key and will include any add-on
indicator cards.
Note: The test will not start if there is a genuine alarm condition is present.
The lamp test performs the following two tests while beeping the panel’s internal buzzer until the
completion of the test.
LED test – all front panel LED's shall be illuminated simultaneously. A Lamp test command
will be sent to the add-on modules to instigate their individually controlled lamp test
functionality.
LCD display –all the pixels of the LCD and backlight are activated simultaneously.
The following will also apply:
The lamp test is run while the LAMP TEST key is held.
The test will not start if there is a genuine alarm condition present.
A fire event is recognised during the test, in which case the test will be aborted and the fire
condition will be displayed.
If the results do not match those described above, the operator is required to note it and report it to
the Ampac Service Centre.

5.3 Walk Test
Access level 2
Walk Test and Silent Walk Test is available via the
Menu - Control - - Zone. - Select Zone - Silent Walk Test or - Walk Test
The purpose of the walk test is to verify the detectors, MCP's and optionally the alarm devices
(sounders) are functioning as required. Once a zone has been placed in walk test, the maintenance
personnel can manually activate each detector (or MCP) and check the local indicator is illuminated
and the alarm devices (sounders) operate if selected.
Details of walk test are as follows:
Individual or multiple zones can be placed under test
Zones placed under test can be removed from the test condition via the Zone Control menu
at access level 2 or 3
Selecting “SILENT WALK TEST” performs the test without sounding programmed sounders
Selecting “WALK TEST” performs the test activating associated sounders as programmed
If “WALK TEST” or “SILENT WALK TEST” is invoked the control will toggle to display the
“REMOVE TEST” control
The test indicator is illuminated if one or more zones are placed under test and will remain
illuminated for the duration of the test
When a zone is placed under test the LCD displays a zone status of “WALK TEST”,
“SILENT WALK TEST”, or “C&E WALK TEST” depending on the type of active test
If a fire is registered from within a zone under test the zone status will be displayed as
“WALK TEST FIRE” and sounders will sound if selected. The associated zone fire LED (if
fitted) will also be illuminated
The common fire indicator will not be illuminated if a fire is detected from a zone under test
The “WALK TEST FIRE” condition will not operate the designated Fire Output/s
The “WALK TEST FIRE” condition will be logged and printed
A fire detected from within a zone will be automatically reset every 5 seconds after it is
detected and associated sounders will be activated if selected for that duration. If the device
within the zone remains in fire the zone will re-enter the “WALK TEST FIRE” state, otherwise
the zone will be reverted to the active walk test status and the associated zone fire LED (if
fitted) is extinguish
The test condition can be cleared by selecting “REMOVE TEST” from within the Zone
Control menu for individual zones
Pressing the RESET key also removes all zones placed under test
The walk test may alternatively be initiated as a System Effect in Cause and Effects. The
test will be performed on the zone designated by the Cause and Effect and the programmed
Sounders activated by default. The test will end when this System Effect is de-activated in
the Cause and Effect
Note: The test is not available if a fire condition existed at the panel prior to the test being
invoked

5.4 Device Locator
Access level 2
The Device Locator test is available via
Menu - - Control - - Device - Select Device - Alarm led ON
Device locator allows maintenance personnel to locate a particular device by forcing the device
alarm LED ON. Only devices with physical alarm LED's support this test.
This is a low priority test and can only be performed on one device at a time. Once invoked the user
is prompted that the alarm LED has been forced on and to press CANCEL to end.
The Alarm LED of the device will remain on throughout the duration of the test.
