3.1.1 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’s illuminated until the original fires have
been cleared on that loop.
3.1.2 Analogue Loops
Each FACP supports up to 2 loops. The standard configuration is one loop, enabling the second loop
involves obtaining and plugging in the “Loop Activation Key” into CN7 on the main termination board
and activating it within LoopMaster. The number of loops enabled and the protocol used is
selectable in the configuration software and is site configurable.

5.1 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.
5.1.1 Enclosure Details
LoopSense can be surface or semi-flush mounted, is supplied with a detachable door, a mountable
back box with backpan, power supply and a minimum of two separate PCBs.
5.1.2 Fixing the Chassis to the Wall
Taking into account the weight of the panel securely mount it by using, the three keyhole mounting
holes, suitably sized screws and plugs for the type of mounting surface.
Mounting is best achieved by positioning the box against the surface it is to be mounted to, marking
the holes, taking the box well away from the surface and then drilling the holes.
Caution: Any dust or swarf created during the fixing process must be kept out of the panel and great
care is taken not to damage any wiring or components.

5.1.3 PCB Removal / Replacement
If the PCB’s have to be removed the following precautions should be observed;
Removing the door will provide better access to the boards and ensure the hinges are not
accidentally stressed.
Personal anti- static procedures must be followed.
When disconnecting the 20 way 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.

5.1.4 Removing the Knockouts
Carefully decide how the wiring will be brought into the panel then remove the required knock-outs
for the bushes and cables.
The knock-outs should be removed with a sharp tap in the rim of the knock-out using a flat broad-
bladed screwdriver. Use of excessive force could damage the enclosure around the knock-out.
REMOVING
KNOCKOUTS
Always ensure if a knock-out is removed, the hole is filled with a good quality cable gland. Any
unused knock-outs must be securely blanked off.

6. Electrical
6.1 Primary Power Supply
The LoopSense Power Supply PCB combines the functions of;
A Mains to D.C. switched mode power supply unit that operates from a supply of; 204 - 264VAC @
47 –63Hz supplying the system while all zones are in alarm
A battery charging and monitoring unit
A mains fail is detected when the PSU voltage drops below 24V.
6.1.1 Mains wiring
The requirement for the mains supply to the FACP is fixed wiring, using three core cable (no less
than 0.75mmand no more than 2.5mm) or a suitable three conductor system, fed from an
isolating switch fuse spur, fused at 3A. This should be secured from unauthorised operation and be
marked 'FIRE ALARM: DO NOT SWITCH OFF. The Mains supply must be exclusive to the FACP.
6.1.2 Connecting the Panel
Connecting LoopSense internal connections and PCBs is best undertaken immediately prior to
commissioning. Before beginning ensure all devices on the circuits are correctly connected and that
cable integrity is verified throughout the installation.
Important: DO NOT use an insulation tester ('Megger') with any electronic devices
connected. Faults occurring in the wiring which are not picked up at this stage will almost certainly
result in spurious and intermittent faults when the equipment is energised.
Important: Under no circumstances should the LoopSense panel be operated without the
Power Supply PCB correctly mounted in the enclosure and the retaining screws securely tightened.
6.1.3 Connecting the Mains
The technician should NOT attempt to connect Mains to the Panel until fully conversant with
the layout and features of the Power Supply PCB.
The incoming Mains cable should be brought into the Panel at the top right hand side of the
enclosure, fed through the ferrite core and correctly terminated on the Chassis Earth Terminal and
then to the Power Supply connector block.
Note: Fuse F1 (2Amp (3A supply) or 1.25Amp (2A supply) / 250VAC M205) is field replaceable
Before switching on the Power Supply the Earth MUST be connected to the chassis earth terminal.
All earth cabling must be terminated to the Panel Chassis Earth Terminal in a Star
configuration.
The earth cable closest to the cabinet body must have an M4 SPW beneath the lug then an
M4 SPW and M4 nut.
Each additional earth cable must be terminated with an M4 SPW and M4 nut.
An additional M4 nut and M4SPW are fitted to the earth terminal for installers to connect the
mains earth

6.2.1 Connecting the Stand-By Batteries
The capacity of the batteries to be installed depends on the panel configuration and required stand-
by time. To calculate the required AH capacity of the batteries refer to the calculation guide located
in the rear of this manual.
Two new, good quality and fully charged 12V Sealed Lead Acid batteries are required as the
emergency stand-by power supply for the Panel. They are to be mounted in the bottom of the
cabinet. In the ABS version a protective tray is supplied in the packaging.

Page 10
LOOPSENSE EN54 INSTALLATION & COMMISSIONING
The batteries should be connected in series using the series link wire provided
and located within the panel enclosure. The red and black battery leads from the
Power Supply (TB2) should be run to the batteries in such a way that there is no risk of them being
damaged, and then connect the red wire to the positive terminal and the black wire to the negative
terminal.
The panel's sophisticated battery monitoring protects the batteries against deep discharge by
activating a cut off circuit when the stand-by supply voltage reaches approx 21 volts. If batteries are
not fitted, are discharged or in poor condition, the “FAULT" LED will be illuminated.
6.3 Cable Types and Limitations
All System wiring should be installed in accordance with the national wiring regulations where the
panel is being installed.
To comply with EMC (Electro Magnetic Compatibility) regulations and to reduce the risk of electrical
interference in the system wiring, we recommend the use of Fire-resistant screened cables
throughout the installation, examples of which include the following:
