SMART TERMINAL LOOPSENSE EN54 INSTALLATION &COMMISSIONING
1 Introduction
SmartTerminal has been designed for use with the LoopSense series of FACP’s.
4 line by 40 character LCD with backlight and navigation keys keys allow the
SmartTerminal to be used for FACP operation and interrogation. Note the backlight is only
energised when alarms are present, a key has been pressed or controls enable key switch is
enabled
Buzzer and system Reset.
System expansion capabilities / options:
A wide range of secure user functions. This includes the ability to disable / re-enable a large
number of system functions.
Flush or surface mountable enclosure.
Controls have tactile and audible feedback of operation.
All terminals cater for 2.5mm cables.
SmartTerminal connects to the LoopSense Fire Alarm Control Panel (FACP) via the RS485
multidrop communication port. Generally it is designed to be used anywhere where the status of the
FACP is required to be monitored by local personnel and limited control is required.
Front panel controls that allow the resetting of alarms and activation/silencing of alarm
devices. Enabling operational access to the controls is via a key-switch;
Reports events from devices that are accessible to the host FACP. For example if the host
FACP is configured with global access then the connected SmartTerminal reports events
from all devices. If the host FACP is configured as local then the connected SmartTerminal
reports events from devices that are directly connected to the host FACP.
SmartTerminal essentially consists of two PCBs;
1. SmartTerminal Termination Board. A Termination Board is mounted in each SmartTerminal
to protect and interface the RS485 communications and 27VDC supply to the LCD Board
2. BRD82ICC –Control, LCD Communications and LCD Driver Board
SmartTerminal can be supplied in two styles;
1. BX05: Slim line SmartTerminal
2. BX1: Standard SmartTerminal
Note:A maximum of 30 SmartTerminal’s may be connected to the communications bus over a
distance of approximately 1.2Kms

2.1 Mounting the Enclosure
The panel MUST be mounted in an area that is NOT subject to conditions likely to affect its
performance, e.g. damp, salt-air, water ingress, extremes of temperature, abuse etc. is at an easily
accessible height and such that the indicators are at eye level.
Typical locations for the panel are the first and most obvious point of contact for emergency services
or a security office that is likely to be permanently staffed.
2.1.1 Enclosure Details
The LCDA can be surface or semi-flush mounted, is supplied with a detachable front door,
mountable back box and a minimum of two separate PCBs.
2.1.2 Fixing the Chassis to the Wall
Taking into account the weight of the panel securely mount it by using the three keyhole mounting
holes in the backpan, two in the top and one in the bottom. Use suitably sized screws and plugs for
the type of mounting surface.
Caution: Any dust or swarf created during the fixing process must be kept out of the cabinet and
great care should be taken not to damage any wiring or components.

2.1.3 Board Removal / Replacement
If a PCB has to be removed the following precautions should be observed;
Removing the door will provide better access to the boards and will ensure the hinges are
not accidentally stressed.
Personal anti- static procedures must be followed.
When disconnecting the RJ45 style connecting cable from the PCB, make sure that the
cable remains connected to at least one board to prevent it being misplaced.

Note: Care should be taken when detaching this connector as it is necessary to depress the
small locking tab to unlock the connector from its base. To reconnect the cable the connector must
first be correctly aligned then pushed into the socket so it locks into position.
Carefully remove the retaining screws at each corner of the board taking care not to damage
any of the components.
Place each board into anti- static storage once removed.

Figure 5: LCD Printed Circuit Board Layout
Open the front door; locate the “CONFIG” button situated on the left hand side of the PCB and press
for 3 seconds. The buzzer and “Config” LED will double beep and flash respectively to indicate that
the Configuration mode has been entered. The LCD will now display the Configuration screen. This
screen consists of the code version number, current address and four adjustment markers. These
markers A-, A+, C-, and C+ are used to indicate the keys that adjust the address and LCD contrast.
Use the “PREVIOUS (A-) and NEXT” (A+) keys to select the desired address. The default value for
this address is 255 which is not a valid SmartTerminal address. The user must then select an
address value from 1 to 30, i.e. the same address as that set in the FACP. The keys corresponding
to C- (ACK) and C+ (RESET) are used in a similar manner to decrease and increase the LCD
contrast level. There is audible feedback for all key presses.
Once the address has been set press the “CONFIG” button again for 3 seconds and the screen will
return to its default and the “DIANOSTIC” LED will return to a slow flash. This slow flash indicates
SmartTerminal and the FACP are communicating normally i.e. the LED flashes if communications
data is being received from the FACP.
Note: If the address is not set within the time out period of approximately 75 seconds
SmartTerminal will return to its normal state.

5 Setting the SmartTerminal in LoopMaster
This section assumes the engineer has experience in the use of LoopMaster and hence has an
understanding of it operation. To commence the programming go to the “Tree View” within
LoopMaster as shown below.
The Tree View
Figure 6
The above shows the expanded view of the SmartTerminal add on type. In the case above the panel
in question has 1 SmartTerminal assigned to it, entitled ‘Panel Add-on 1’.
Selecting one of these add ons will update the Details Pane with the respective module’s
information, while double-clicking on the add-on will open its editing dialog box.
The SmartTerminal Menu
Right-clicking on the SmartTerminal add on parent item from the Tree View opens the menu,
It contains an option to add a panel Add-on to the panel.
Right-clicking on an existing SmartTerminal add on from the Tree View opens the menu,
It contains an option to add another or remove the current Add-on or via
the ‘Edit Properties’ option to open the Add on editing dialog box.
Note: that it is possible to have a maximum of 30 SmartTerminal add ons per panel, however,
this value will reduce as other add-on types are added (the entire panel can have a maximum of 30
add-ons, of any type, at any one time).
The Details View
Figure 7
The above is displayed as part of the SmartTerminal Details Pane representation of the information
available to the configuration of the data. It is displayed at the top portion of the Details Pane and is
a non-editable, accurate representation of editable fields for a SmartTerminal.

10
SMART TERMINAL LOOPSENSE EN54 INSTALLATION &COMMISSIONING
The List View
Figure 8
The SmartTerminal add on List View appears immediately below the SmartTerminal add on Details
View and consists of a summary of all available SmartTerminal add ons assigned to the current
panel. In the above, there are 2 add on SmartTerminal’sassigned to this panel, entitled ‘Panel Add-
on 1’ and ‘Panel Add-on 5’ respectively.
Double-clicking on an entry in the list opens the editing dialog box for that particular SmartTerminal.
Editing
Figure 9
The SmartTerminal add on editing dialog box consists of two types of fields:
1. Non-editable (informational) fields:
Panel –The panel number this module belongs to,
Address –The hardware address of this particular module; addresses can be in the
range of 1 to 30,
Reference –The reference number of this module
2. Editable fields:
Multicast Type –The user can select one or more Multicast Types for this module to
process,
External –If this checkbox is checked then this add on is to be used on the external
bus,
Descriptor –Allows the user to enter a 40 character descriptor describing this add
on

SMART TERMINAL LOOPSENSE EN54 INSTALLATION &COMMISSIONING
6 Operation
The operation of SmartTerminal can be considered to be in one of three states, these are;
1. Power up - when the SmartTerminal is initialising
2. Normal - when the SmartTerminal address has been set and is communicating with the
FACP, reporting normal / abnormal conditions and controlling the FACP via the front panel
controls
3. Fault where the SmartTerminal is in fault and/or is unable to communicate with the FACP.
Power Up
The LCD displays a message telling the operator SmartTerminal is being powered up and that the
hardware is being initialised. Once the hardware has been successfully initialised set the address
and SmartTerminal should automatically transition to the normal state. Should a failure occur on
power up press the “RESET” button located on the LCD PCB (see Figure 5) and check the address
is correct.
Normal
The Normal state is entered from the “Power-up”or a return from the “Fault”state and is displayed
on the LCD if the SmartTerminal is communicating with the FACP and operating correctly. In this
state the front panel Power indicator is illuminated.
Fault
SmartTerminal enters the Fault state upon;
A hardware failure
LCD module failure or
A loss of communications with the FACP (indicated by the “DIAGNOSTIC” LED – not
flashing and the “no communications“ message being displayed)
In a Fault condition the front panel NORMAL indicator is extinguished and the details of the fault are
displayed on the LCD. The FACP will also indicate a fault in a similar manner.
