➢Password entry
➢Flush or surface mountable enclosure. A surround is required for the metal cabinet
➢Controls have tactile and audible feedback of operation
➢All terminals cater for 2.5mm cables
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.

4.1 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.
4.1.1 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.

MAN2997-2

4.1.2 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.

4.1.3 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.

4.1.4 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.

5.1 Primary Power Supply
The LoopSense Power Supply PCB combines the functions of;
A Mains to DC. switch 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.
5.1.1 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.
5.1.2 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.

MAN2997-2
15
5.1.3 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) 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

5.2.1 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.
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.
5.2.2 Battery Cable Test
Battery cable fault detection is only available when using the PSU 2397 3 Ampere power supply.
A “BATTERY CABLE FAULT” is registered when the combined internal resistance of the battery and the
resistance of the battery leads exceed approximately 1.2Ω. This test is conducted every 8 seconds in
conjunction with the check for battery missing.
5.2.3 Battery Capacity Test
This test is conducted every 36 hours for duration of 36 minutes provided the system is not in the Fire
condition.
During the test, the charger is turned off and the PSU dummy load is engaged; if the battery voltage drops
below 24.4V during this time, the load shall be disengaged and a “BATT CAPACITY FAULT” shall be reported
and latched for the remaining duration of the test.
If the system enters the Fire condition during the test, the test shall be aborted and if the system is in Fire
prior to the test commencing, the test shall suspended until the Fire condition is reset.
Note: While the Battery Capacity test is in progress, the Battery Cable Fault and Charger Fault tests are
suspended as they cannot be conducted concurrently.

MAN2997-2

5.2.4 Charger Voltage Test
A charger low condition is recognized when the charger voltage drops less than 0.8V below the optimal
charger voltage for a given temperature. A charger high condition is recognized when the charger voltage is
more than 0.8V above the optimal charger voltage for a given temperature.

5.2.5 Charger Fault Test
A Charger fault test is performed every 14 minutes for duration of approximately 10.5 seconds. It effectively
confirms if the charger is able to recharge the battery by discharging the battery slightly using the PSU
dummy load then attempting to recharge the battery. If the charger has successfully recharged the battery
(Delta V > 100mV) then no fault is reported, otherwise a charger fault is reported.
5.3 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:
