Introduction
Floodline leak detection systems are designed to detect water/liquid leaks within buildings. The alarms
generated by the Floodline systems allow early action to be taken to prevent damage, reduce disruption and
limit loss caused by unnoticed leaks. Floodline systems are installed in sensitive and critical areas to give early
warning of leakage from any source and typical installations include modern offices, call centres, historic
buildings, communication rooms, dealing rooms, etc. Floodline systems operate on a zoned principle and an
alarm in one zone has no effect on the function and normal monitoring of other zones within the same system.
The Floodline 128 control panels operate a network of leak detection zones and each zone may be a short
length or a single point - or - many metres in length or multiple points. The whole system is continuously
monitored for leaks and continuity.
The zoned principle of the Floodline systems has several distinct advantages:
1. Each zone is separate and an alarm in one zone has no effect on the normal
function of the rest of the system.
2. Each zone is continuously monitored for either leak or system fault.
3. Different types of sensors can be “mixed and matched” from zone to zone to
meet installation requirements.
4. True multi-zoning means the system can handle, display, and report any number
of simultaneous alarms.
5. No minimum or maximum zone length or size.
6. Separate volt-free (relay) outputs can be provided for each zone allowing
comprehensive information to be transmitted onwards and which can allow
zone prioritisation, i.e. “double-knock” facility.
7. Cost of installation can be better controlled through choice of zone size.
8. Systems are easy to install, service, repair and operate.
9. Systems are easy to customise to individuals current and future needs.
Floodline 128 Multi-Zone System
The system will be controlled by one or more FLOODLINE 128’s, which are available with zones sizes of 32, 64,
96 and 128. The control system consists of a base unit and a control unit. The base unit houses the system
power supply, detection modules and main control circuitry. The control unit displays full text descriptions of
any current alarms and provides further visual and audible indication that an alarm is active. The user/engineer
controls and sets up the system from the control unit. The 32, 64, 96 and 128 zone base units are all the same
physical size and are wall mounted and can be fixed locally to the detection areas or remotely in a convenient
plant or equipment room. The control unit can be mounted locally to the base unit or remotely in an office or
reception area along with other alarm systems. Each system is an isolated, stand-alone unit, requiring a
220/240Volt 50Hz mains power supply and is complete with integral sealed lead-acid battery for back-up.

FL 128 Multizone System 15.01.2021 7
When a zone or certain system alarms are detected a full text message of the nature of the alarm is displayed
on the control unit’s LCD, a red LED indicator flashes and buzzer sounds. Any person pressing the MUTE button
can silence the buzzer, but this does not cancel the alarm or clear any of the visual alarms.
A zone can be in one of 4 states:
•Normal (no alarms).
•Short Circuit.
•Open Circuit.
•Leak Detected.
In addition to the above alarms further system self-test alarms can be generate as listed below
•Drop Dead (complete power failure)
•Mains Fail
•Low Battery
•Remote Disconnected
•Display Disconnected
•Display Communication Failure
•Module communication Failure
A range of volt-free contact, changeover output relays are included for: -
Drop Dead (complete power failure) rate at 5Amps @ 28Vdc.
Mains Fail rate at 5Amps @ 28Vdc.
Common Leak Detected (in any zone) rate at 5Amps @ 28Vdc.
Common System Fault (open and short circuit faults any zone) rate at 5Amps @ 28Vdc.
Self-test (For low battery, communications failure alarms, remote/display disconnect alarms) rate at 5Amps @
28Vdc.
The Location of the relays on the motherboard housed in the base unit is shown in Appendix A.
Individual volt free changeover relays can be provided as an optional extra to give an output for LEAK detection
per zone. These can, in turn, be wired together to provide a single additional output for a group, or groups, of
zones. This can be a useful technique in prioritising, or ranking the importance of individual areas, ie. “double
knock”.

FL 128 Multizone System 15.01.2021 8
In the event of an alarm the appropriate relays activate providing a “clean contact” output for connection to a
remote monitoring system, BMS etc. Although the mute button being pressed can silence the buzzer the relay
outputs can only be cancelled by using the control unit’s menus.
The standard output relays can also be linked and the three options available are:
1. Individual Alarm Outputs.
2. Leak Detected and System Fault Linked, Mains Fail and Self-Test Linked.
3. Leak Detected, System Fault Linked, Mains Fail and Self-Test Linked.
This allows for a common output to a BMS etc. DIP switch SW1 on the mother board sets the above linking
option and the various setting are shown on the diagram in Appendix A.
Floodline Sensors
The Floodline range of dedicated water (and other liquid) detecting, or sensing devices can be used in any
length, number, or combination to satisfy the particular requirements of the installation.
•Single Zone Detection Tape.
•Multi -4- Zone Detection (Sensing) Cable.
•Multi -8 -Zone Detection (Sensing) Cable.
•Point Sensors.
•Flexi-Pad Sensors.
•Pipe-In-Pipe/Overflow Sensor.
•Oil Sensor.
Sensing devices are installed to monitor liquid leaking from wet services, pipes, tanks, drains, roofs, etc., and
can be applied in a wide variety of ways. For example:
Multi-Zone Detection (Sensing) Cable/Tape may be laid under raised floors, in drip trays, laid on top of
suspended ceilings or attached directly to pipes (not multi-8-zone cable). Point Sensors (or Oil Sensors) may
be used in bunded areas and floor trenches or fixed at floor level at strategic points around the room or site.
Flexi-Pad Sensors may be wrapped around pipe joints or valves or inserted into confined spaces. Pipe-in-Pipe
Sensors may be mounted directly into overflow pipes and double skin/double containment pipes. All sensors
(except Oil Sensors) react to water and other aqueous liquids. Oil Sensors will react to ANY liquid and are
designated “OIL” to differentiate them and to reflect their usual application.
In common with all types of leak detection system the liquid must physically contact the sensor for the
alarm to be activated.
ALL devices can be wetted and dried repeatedly unless contaminated with a liquid or substance, which
irrevocably changes the electrical characteristics of the device or leaves a coating or residue, which
prevents correct functioning.

FL 128 Multizone System 15.01.2021 9
Principle of Operation
The Floodline system works from the principle that water, or other conductive liquid must touch one or more
of the sensors for an alarm to be activated. (Any liquid will activate the OIL Sensor).
The system essentially detects differences in loop resistance on each of its zone inputs. The leak detection and
system fault alarms are activated when the loop resistance falls between, below or above set limits as detailed
below.
•0to 1kShort circuit causing SYSTEM FAULT alarm
•1kto 300k* Water detection casing LEAK alarm
•300k* to 4M:- SAFE - no alarm,
•above 4MOpen circuit causing SYSTEM FAULT alarm
*Or less according to sensitivity setting - see later.
The system will not be activated by humidity alone but condensation dripping on to the detection cable due to
the humidity may activate a leak alarm depending on type of sensor used and amount of condensation present.
If the system is wetted, for whatever reason, the alarm will be activated. If the system is likely to be
installed in an area, or in conditions where minor, occasional drips might occur and are to be ignored
then care should be given to the routing and position of the sensors to minimise any apparently
“spurious” or unwanted alarms.
Floodline 128 Control System
The standard Floodline 128-leak alarm system is available in 32, 64, 96 or 128 zone configurations. The control
system consists of a base unit and a control unit.
Base Unit
Introduction
The base unit houses the main control board (motherboard), the battery backed power supply, the 32-zone
leak detection modules (1 to 4), the individual zone output relays (if fitted) and the communication module (if
fitted). All wiring from the leak detection sensors and onward communications wiring is brought to the base
unit which can be houses at a suitable location i.e. riser.
The base unit is an isolated, stand-alone unit and requiring a 220/240VAC 50Hz mains power supply and is
complete with integral sealed lead-acid battery back-up. A range of warning and status indicators are mounted
on the front of the base unit to show Power On, “Display Disconnected” and “Display Comms Failed”.

FL 128 Multizone System 15.01.2021 10
Mounting Floodline 128 Base Unit
The base unit is mounted on the wall surface and raised mounting bosses in the rear of the case at each corner
allow for fixing with wood screws or bolts etc. A key slot is provided in the back /top of the case to enable the
control panel to be hung temporally on 1 fixing for leveling and marking the mounting bosses. The base unit
should be fixed at a convenient level for inspection and to ensure that the door release fastening is accessible.
20mm cable entry points are provided in the top and bottom of the case.
Connection of Mains Supply
The mains supply to the base unit is 220/240Vac 50Hz and should be via a dedicated fused spur fitted with a 5
Amp fuse. An IEC plug and socket are provided for connection of the mains supply.
A retaining clip is provided with the IEC plug to ensure it is not accidentally disconnected.
The Floodline 128 must be provided with an EARTH (Ground) to ensure correct operation and for safety
reasons. If the base unit is not correctly earthed Andel Limited cannot guarantee correct operation of
the system.
Connection To Control Unit
The base unit must be connected to a Floodline 128-control unit. The connection can be made using any 6-
core cable with a minimum rating of 15Volts at 1Amp. The table below lists the connections at the base unit
and which they are connected to in the control unit.

FL 128 Multizone System 15.01.2021 11
32 –Zone Leak Detection Module
The 32-zone leak detection module are house in card slots within the base unit and connect to the
motherboard via a ribbon cable. A read indicator on each module shows that it is connected. The base unit can
handle up to four 32-zone leak detection modules giving a total of 128 zone if required. The wiring to the
module is via plug and socket terminal blocks with 8 zones per connector. The zone numbering of each module
is determined by which connector on the motherboard the unit is plugged into and is listed below:
1. Zones 1 to 32 JP1 on motherboard (connectors numbered left to right)
2. Zones 33 to 64 JP2 on motherboard
3. Zones 65 to 96 JP3 on motherboard
4. Zones 97 to 128 JP4 on motherboard
Connection Of the Leak Detection Sensors
Incoming wires from the detection devices are connected to the “Zone Input Connections“terminals on each
32 Zone. “Sleeper” resistors are factory fitted across the C and n terminals of each zone’s input terminals for
testing and transport purposes and should be removed as each zone is connected. The “sleeper” resistors are
left in place in any unused zones.
“Sleeper” resistors are 1Mand simulate the end-of-line resistor built into some devices e.g. Multi-Zone Cable
Junction Boxes, Oil Sensors and Pipe-in-Pipe Sensors - no additional end-of-line resistor is needed in those
devices. Point Sensors or Flexi-Pad Sensors DO require an end-of-line resistor fixing into the last device in line in
a zone (or the only device if there is just one in the zone). For convenience, the “sleeper” resistors can be used
for this purpose and can be taken from the zone input terminals and fixed into the output terminals of the last,
or only, device.
The specific installation and wiring details of each of the sensor is detailed in later sections.
Control Unit
Introduction
The control unit gives full text descriptions of any current alarms and also provides further visual and audible
indication that an alarm is active. The user/engineer can control and set up the system from the control unit
and the available controls are described in a later section. The various control keys etc on the control unit are,
menu key, up and down scroll keys, enter key, mute button, alarm active indicator, display window and menu

Control unit Communications Failure
A control unit communications failure alarm is generated when communications between the base unit and the
control unit has failed. When a control unit communications failure alarm is generated the audible alarm in the
base unit pulses along with the “Display Comms Failed” alarm indicator on the front of the base unit. The self-
test relay in the base unit will also activate if the relays are armed. The control unit will also generate an alarm
if only the communications has failed. The audible alarm within the control unit will activate, the alarm
indicator will flash, and the display will display “comms fail” as shown below:

To mute the audible alarm press the mute button on the front of the control unit. The audible alarm will
reactivate after 1 minute as communications failure to the control unit means the system in non-functioning
and should not be ignored.

FL 128 Multizone System 15.01.2021 15
Display Disconnected Alarm
A display-disconnected alarm is generated if the physical connection between the base unit and the control
unit is lost. When a display disconnected alarm is generated the audible alarm within the base unit pulses, the
self-test relay activates if relays are armed, and the “Display Disconnected” indicator on the front of the base
unit activates. It is not possible to mute the audible alarm in the base unit.
Mains Failed
A mains failed alarm is generated when the incoming mains supply to the unit is turned off and the battery
takes over supply to the unit. When a mains failed alarm is generated the “Mains Ok” indicator on the PSU
board turns off and the mains failed relay activates. No further visual or audible alarms are generated, as the
system will operate until the battery is drained and a further alarm is given when the battery’s charge begins to
fall below a set limit.
Drop Dead
The drop-dead alarm activates when all power to the system or the power supply circuitry within the system
has failed. When a drop dead alarm is activated the normally active “Drop Dead” relay deactivates. No further
indication is given.
Low Battery Alarm
This alarm is generated when the battery voltage drops below 10.2 volts and although the system will still
operate at this voltage the alarm relays will not activate. When a low battery alarm is generated the audible
alarm in the control unit is activated, the alarm indicator on the control unit flashes and the display window
indicates that a low battery alarm is active as shown below. The self-test relay in the base unit will also activate
if the relays are armed and the “Battery Ok” indicator on the PSU board will turn off.
