Overview of the Hydrosense Water Detection System
The Hydrosense water detection system is designed to detect the intrusion of water in
concealed areas or any place where water penetration must be identified so that corrective
action can be taken immediately.
It will continuously monitor the potential hazards 24 hours a day and has the facility for 24
hours battery standby in the event of power failures.
Any water penetration detected will be signalled to a control panel that can give audible and
visual alarms.
The detection system comprises of three basic components, water detection cable, localised
probes and a control panel.
Water leak detection systems can be divided into two basic categories:
(a) Linear Detection
(b) Point Detection
The Hydrosense supports both types on the system

Detection Components
Linear Detection- Hydrowire Cable
Where floor areas, ducts and
suspended ceilings need to be
protected this is usually best achieved
by installing lengths of Hydrowire.
Hydrowire is a highly conductive cable
extremely sensitive to moisture. It is
available in 5 metre lengths (HYDW-05)
or 10 metre lengths (HYDW-10).
Each length of Hydrowire is terminated with a male and female 4 way plug to enable them
to be plugged together up to maximum zone length of 50 metres and terminated with an
EOL. It is connected to the panel through the Connection Interface. As soon as the cable
detects moisture this will trigger an alarm. For the cable to measure water on the surface
then it is recommended that the cable is fixed down with Hydrosense fixing clips (HY-
FXSA)
Linear Detection EOL
Each Hydrowire is terminated by an End of
Line Device (HS-HWCI-EOL), which
enables it to be continuously monitored for
defects.
Linear Detection Connection Interface
Each Zone of linear detection cable is
plugged-in to the Connection Interface
module (HS-HWCI) that allows
connection to the control panel using
standard 1.5mm2 2-core cable HYLCB.
Floor Probe Junction Box
Each floor probe is simply plugged-
in to the Junction Box (HS-WLJB)
that allows connection to the control
panel using standard 1.5mm2 2-
core cable HYLCB

Point Detection Floor Probe
Where a requirement exists for more localised
detection, such as HVAC plant, drip trays, elevator
shafts and storage areas a floor probe (HS-WLDP) can
be installed.
As with the cable the detection of moisture triggers an
alarm and is also monitored by the line fault circuit of
the control panel. Additionally the probe has an LED
indicator on top to identify exactly which probe has
been activated. Up to 20 detectors can be used in each
zone. The probe is simply plugged into the system
using the Junction Box.
Probe is fitted with a 1m cable.
If the distance from the junction box to where the probe needs to be mounted is more than 1m
then additional Extension leads are available in 1m (HY-ZB01), 3m (HY-ZB03) and 10m (HY-
ZB10) lengths.
Control and Indicating Equipment of a Hydrosense System
Control Panel (2 to 8 Zones)
HSCP Series – This panel is available in 2, 4 and 8 zone
configurations. These are fully programmable and allow the
addition of Ancillary PCBs, repeater panels and a Mimic
Display.
Ancillary PCBs provide a means to extend Alarm, Fault,
coincidence and Zonal alarm volt free contacts to locations
remote from the control panel via a 2-core data bus
(RS485).
Hydrosense Mimic Panels
The Hydrosense Mimic Display uses flexible fibre optic guides to illuminate areas on a floor
plan. This provides a clear, geographical indication of the alarm activation enabling a speedy
identification of the source and location of the alarm.
This unique system dispenses completely with wiring and
enables indicators to be moved, removed or added without the
need for any wiring.
It can only be used with the HSCP range of panels.

Design & Planning
Design Notes
!Water finds its own level so careful consideration must be given to slopes and dips in the
area to be protected.
!Can the cable be installed to avoid doorways and traffic.
!Floor probes can be used to protect wells, cavities or hollows.
!Is the site occupied? If so, will the site require just visible alarms or will there be a need
for conventional or voice enhanced sounders?
!Is a remote signalling device required?
!How is the cable to be fixed to the floor? Are other services going to interfere with it?
!Check with the building owner or manager for future plans or designs that may alter the
requirements or siting of the equipment.
!Will the system require expansion? Give consideration to the possible addition of extra
zones.

lift the fascia gently away from the box towards you. With the fascia removed there is much
more room inside the panel for making off and dressing cables. When cabling work is
complete the fascia can be re-fitted with the two countersunk screws and the red,
green/yellow and black wires re-connected to the three way terminal block
NOTE: It is most important that the polarity of the red and black wires are observed as
wrong connection of these will damage the control panel.
Connecting to the circuit board
All connections for field wiring are to a single row of terminals along the top of the circuit
board. The connections for the power cables are to a pluggable terminal block, which may
be pulled off of the board to remove the plate/PCB assembly. Remove this pluggable
terminal only with mains power off. For Zone connections twin PVC cable with conductors of
.75mm to be used and plastic or metal cable glands can be used for all connections to the
panel.
The resistance of any core of any cable must not exceed 25 ohms.
Wiring should enter the enclosure at the top of the panel using the knockouts provided and
be formed tidily to the appropriate terminals leaving enough wire to ensure that there is no
strain on the PCB. Terminals are capable of accepting wires of up to 2.5mm
Figure 2
Terminal designations
Wiring must not go across the front of the circuit board plate or between the plate and the
circuit board. If cable entries need to be in positions other than at the knockouts provided,
wiring must be fed behind and well away from the surface of the circuit board. The space at
the bottom of the enclosure is occupied by the standby batteries so this must be borne in
mind when considering cable entries.
Remote Inputs
Some functions of the control panel can be controlled externally from the panel if required.
Operation of these inputs should be restricted to access level 2 control. These are
abbreviated at the terminals block as follows:
a) Remote 0V supply - ROV d) Fault – FLT
b) Silence Alarm – SIL e) Reset – RST
c) Sound Alarm – AL
To activate these inputs, the remote 0 Volt (R0V) supply must be connected to the input via
a normally open switch or contact and via a resistance of no greater than 100 ohms.
All of the remote control inputs are non-latching.

All repeaters are now configured and the control panel will report a fault if any repeaters that
have been accepted become faulty or go off line.
Ancillary Boards
Connect the RS485 bus and power to each Ancillary board. Up to 7 Ancillary boards may be
connected and each board has terminals for the incoming cables and outgoing cables. All
except the last RS485 device must have the jumper links J2 removed.
Set the ancillary board address using the DIP switch (SW2); ensure no two ancillary boards
share the same address.
Apply power to main panel and all ancillary boards then turn on the enable key-switch and
set the write enable slide switch to on, briefly press the PROCESSOR RESET button on the
main panel, wait for a few seconds and the main panel will show the addresses of the
ancillary boards that were found on the display for instance o1 indicates that an ancillary
board at address 1 has been found.
Press the ENTER button to accept each ancillary board that has been found.
The control panel will report a fault if any ancillary boards that have been accepted become
faulty or go off line.
Sounder circuit wiring
All sounders must be of the polarised type. If non-polarised sounders are used the control
panel will permanently show a fault condition.
Sounder circuits are monitored for open and short circuit faults by placing a 10K end of line
monitoring resistor across the last device on the circuit.
Sounder circuits must be wired as a single, radial circuit with no spurs or T junctions to
enable the monitoring circuit to work correctly.
A maximum of 1.6 Amps is available for powering sounders with a maximum load of 0.41
Amps on any one circuit.

Detection zone wiring
The detection zones provide a nominal 24V DC to power the Hydrosense devices.
The wiring is monitored for open and short circuit fault conditions by removing the 6K8 end
of line monitoring resistors that are supplied fitted to the control panels’ terminals and
placing it in the last Hydrosense Probe junction box or discarded if Hydrowire Connection
Interface is wired to the zone circuit. Detection zone circuits must be wired as a single, radial
circuit with no spurs or T junctions to enable the monitoring circuit to work correctly.
Control relays
Volt free changeover relay contacts are provided for local control and signalling if required.
These contacts are rated for switching signalling circuits only and the maximum 30VDC
1Amp should not be exceeded under any circumstances.
Typically, the Aux 24V output of the control panel is switched through these relays and used
to control other systems.
Fault relay
The fault relay is normally energised and will de-energise upon any fault condition including
total loss of power.
Local Alarm relay
The local fire relay will energise upon activation of a alarm condition on any of the zones or
pressing of the sound alarm button on the front panel. The relay will remain activated until
the alarm is silenced or the panel is reset. This relay will not operate upon activation of the
remote AL input or when an alarm condition is triggered on a zone that is in test mode. This
makes the Local fire relay suitable for inter panel signalling without the panels latching each
other.
Alarm relay
The alarm relay will energise upon activation of an alarm condition on any of the zones. The
relay will remain activated until the control panel is reset. This relay will also operate upon
activation of the remote AL input and the sound alarm button.

DO NOT set option codes that are not listed in the above table, setting of unlisted options
may have unintended and serious consequences.
Once the required configuration options have been set, the Access level 3 switch must be
returned to its normal position. The General fault indicator will remain lit if the Access level 3
switch is not turned off.
Internal Switches
Watchdog Reset switch (W/Dog Reset)
If for any reason the microprocessor in the control panel fails to carry out its operation
correctly it will attempt to restart itself. This process is called a “watchdog” and the control
panel must record and indicate these events.
If a watchdog event occurs, the control panel will show the FAULT and SYSTEM FAULT
LEDs on the front panel, the CPU fault LED inside the panel and the buzzer will sound. This
fault can only be cleared by pressing the Watchdog Reset button on the PCB inside the
control panel. This is a serious failure and the control panel buzzer will continue to sound
until the watchdog activation is reset.
Processor Reset
Once started, the microprocessor controlling the panel should continue to run the panel
continuously without interruption. If the microprocessor fails to run, it can be reset by
operating the Processor Reset button on the PCB.
This should not normally be necessary but should be done as a matter of course if the
system is behaving abnormally. The system should resume normal operation within a couple
of seconds of pressing the Processor Reset button.
Write Enable
Changes to the configuration as listed in table above require that the changes be stored in
the control panel memory. To enable the memory to be written to it is necessary to operate
the Write Enable slide switch.

Internal Indicators
Mains fail
Indicates that the 230V AC supply is not present and the system is running on standby
batteries. If there is not a power cut, check the panels mains fuse.
Batt Fail
Indicates that the standby battery has become disconnected or that the charging circuit of
the control panel has failed. Check that both batteries are connected and linked together.
Test battery. Disconnect battery and ensure that 28 Volts can be measured on battery
charger leads.
CPU Fault
Indicates that the central processor unit has failed to correctly execute code and has been
re-started by the system watchdog. The Watchdog Reset switch must be pressed to clear
the CPU fault condition.
Press Watchdog Reset. If system does not return to normal then the panel is probably
damaged and needs the circuit board replacing.
Aux 24V Fault
The Aux 24V and R0V terminals provide a 500 milliamp, 24V DC power supply for power fire
alarm ancillary equipment. This LED indicates that fuse protecting the R0V output has
operated and the rating of this output has been exceeded. The fuse is a self-resetting type
and the supply will resume when the fault condition is removed.
Batt Low
Illuminates when the system is running on batteries and the battery voltage is between 21.5
V and 20.5 V (the minimum battery voltage).
Comms Fault
Indicates that communication has been lost with a repeater panel or Ancillary board. Check
for comms fault at all repeaters and ancillary boards to identify the source of the problem.
Earth Fault
Indicates that part of the system wiring is connected to earth. Remove all system wiring and
re-connect cables one at a time until the earth fault returns. This will indicate which cable the
earth fault is present on.
Sys Fuse Fault
Indicates that the total power rating of the power supply has been exceeded and that the
system fuse has come into operation. Remove and review all loads and re-connect one at a
time until over rated circuit trips fuse to identify troublesome circuit.
S1 and S2 fault
Indicates a short or open circuit on sounder outputs. Remove wiring and refit end of line
resistors. Check sounder circuit wiring.

Hydrowire Installation and Commissioning
Hydrowire Installation HSHWI-100
Mount the Connection Interface to the area where the start of the Hydrowire is to be
mounted. Wire the Connection Interface back to the Hydrosense Control Panel as shown in
Hydrosense Wiring section.
1. Connect the lengths of Hydrowire to be used in the zone and terminate with an EOL
(HS-HWCI-EOL). Plug the Hydrowire into the Connection Box (HS-HWCI). Power up
Control panel and Check that no fault or alarm is reported on the connected zone.
2. Remove the end of line plug and check that a Fault is reported.
3. Remove power from the Control Panel. Disconnect the Hydrowire and store ready for
installation.
4. Ensure that the installation area is clean and free from water, dust and debris.
5. Plan detection route and mark floor and install clips (HY-FXSA) to the area to be
protected so that the distance between any two Hydrowires is no more than 2 metres.
(For localised protection of sources of potential water leakage, such as air conditioning
and water filled radiators, the distance between Hydrowires may be greater).
6. Plug the Hydrowire cable into the Connection Interface, then lay cable to the first clip
ensuring cable not taught, fit into clips and then push clips down to retain the cable. At
the end of the Hydrowire cable fit the EOL (HS-HWCI-EOL).
7. The Hydrowire cable should be installed so that it remains in contact with the floor for as
much of its length as is possible. Great care must be taken when using other fixing
clips. Although the cable is quite sturdy is can be damaged by crushing or excessive
bending. A bend radius of 150mm is recommended as a minimum.
8. The product label should be left such that it is clearly visible.
Note:Hydrowire should not come into contact with surface temperatures greater than 70oC.
Lengths of greater than 50 metres are not permissible from the Connection Interface, this
distance includes Hydrowire and any Zone Extenders fitted.

Hydrowire Wiring
The HS-HWCI Connection Interface allows the Hydrowire to be plugged in and provides the
installer the option of connecting a Remote Indicator.
The Zone In + and – terminals inside the Connection Interface must be connected via a
1.5mm2 2-core cable (HYLCB) to the Z+ and Z- terminals at the control panel.
Figure 8
The end of line (EOL) resistor at the control panel can be discarded.
It is advisable to leave the lid off the control panel until all testing is complete.
NOTE: The Connection Interfaces cannot be daisy chained together, only one Connection
Interface can be connected per zone.
Hydrowire Remote Lamp Connection
In some installations, particularly in floor voids, it is desirable to identify the area in which
water has been detected with a remote indicator unit (HY-WLRI-F) mounted above the void.
This can be achieved by wiring a HY-WLRI-F remote lamp unit to the –ve and +ve of the RIL
terminals in the HS-HWCI Connection Interface.
NOTE:Only one remote lamp unit can be connected to each Connection Interface.
