1. Introduction
The Hydrosense ID is an addressable water leak detection and alarm control panel with 16 zonal LED indicators
and is available in models with either 1 or 2 detection loops. Each loop can support up to 127 loop-powered I/O
modules.
Any number of devices can be allocated to any zone ensuring that any system configuration can be easily
accommodated.
To ensure that the system is installed and commissioned with the minimum of trouble, it should be carefully
planned before the installation is begun.
This involves allocating an address to each device and allocating a message of up to 40 characters (including
spaces) to each address to assist in the location of the devices. Each sub-address can also be allocated a text
message so the actual location of the sensing element can bet determined, the panel supports up to 800 sub-
addresses.
Devices should then be grouped into zones in accordance with the equipment to be monitored / protected and
building plans.
The control panel can be configured using the switches on the front as described in the menu descriptions within
this manual or more comprehensively, using the Loop Explorer PC (LE2) configuration utility and download lead
(IDAP-LEAD) which is available as a separate item.
The Hydrosense ID control panel offers an extensive list of features and options for the control and monitoring
of plant, equipment and sounders, which can be configured via the Loop Explorer PC (LE2) configuration program
or the front panel controls. The Cause & Effect configuration enables comprehensive systems to be implemented.
A Water Leak Detection module for example, may have a main address of 123, input 1 sub-address 123.1 and
input 2 sub-address 123.2. (Three addresses from 800 available).
The sub-addresses can be treated as if they were individual addresses i.e. each can be allocated to any zone,
given an individual address message and be operated by different cause and effect tables.
Although unlikely to be exceeded, the maximum number of sub-addresses available should be taken into
consideration when designing systems that contain large numbers of I/O units.
Important: This control panel should be used only with compatible Hydrosense ID system components.

4.1 Installation
The installation of the panel should be carried out by qualified personnel only. The electronic components within
the panel are vulnerable to physical damage and damage by electrostatic discharges.
It is advisable to wear a wrist strap designed to prevent the build-up of static charges within the
body, before handling any electronic circuit boards.
Never insert or remove boards or components with the power on. To avoid this hazard a Mains
Isolator Switch should be installed.
Mounting the Cabinet
The site chosen for the location of the panel should be clean and dry and not subject to shock or vibration. The
temperature should be in the range -5° to +35° C, the humidity should not exceed 95%.
Open the outer cover using the key provided.
Unplug the power terminal block from the left
hand side of the circuit board, remove the two
screws holding the plate in position and then
remove the complete circuit board and plate.
Hold the assembly by gripping the metal plate
only and try to avoid touching the circuit
board.
Place the plate/circuit board assembly and
fixing screws in a safe location to prevent
accidental damage.
The outer cover can be removed to make
fitting more manageable by removing the two
pins holding it in position on the left hand side.
Remove knockouts from the top and or back of
the box in the positions at which cables will
enter.
When surface mounting use the box as a
template, mark the position of the top-fixing
hole, ensuring that the wall is flat at the chosen
location. The top fixing is a keyhole slot and
fitting a screw here and hanging the box first
will assist in marking the remaining fixing
points.
Screws or bolts of a minimum of 5 mm
diameter and 40 mm long must be used to
mount the enclosure in all three mounting
positions.
After the box is firmly fixed, remove any
knockout blanks and dust or swarf caused by
drilling and fixing the box.
See bezel installation instructions if Semi or
Deep recess mounting.

5. Cabling
It is advisable to fit cable glands and cables before re-fitting the outer cover and plate/circuit board assembly.
Cables should be brought into the cabinet using the knockouts provided and where necessary, using couplers to
maximise the space within the enclosure. Use the knockouts closest to the terminating position for each cable, to
ensure cable length within the enclosure is kept to a minimum.
Ensure that only the numbers of knockouts are removed to meet the cable termination requirements, as any
additional apertures in the enclosure will compromise the IP30 ingress protection requirements.
Brass inlet bushings or cable glands should be used to maintain insulation and to ensure EMC compliance.
The screen or drain wires should be bonded to earth via metal cable glands.
The maximum size of cable, which can be terminated, is 2.52mm.
The communications protocols are highly immune to noise but sensible segregation from known noise generating
sources such as mains cables is recommended.
Detection loop circuit cable size and type is dependent on the number and type of devices used and should be
calculated for each installation.
Cabling for sounder circuits should be sized according to sounder load and cable length but 1.5mm2should suffice
in the majority of cases.
The control panel requires a 230 VAC supply, which should be derived from a separate fused mains isolator
switch, labelled “Water Leak Alarm - Isolator”.
The mains supply must include an earth conductor connected to the fixed installation earthing system of the
building.
This equipment relies on the building installation for protection and requires a 5 Amp protection device. The
mains supply should use cable with a minimum cross section of 1.5 mm2.
5.1. Cable Termination
Drain wires need to be terminated at the brass cable gland to ensure EMC compliance.
To ensure good earth bonding at entry to the panel enclosure, it is recommended that the cable drain wires are
terminated using Pirelli AXT brass cable glands. These glands have a slotted fixing thread, which allows the drain
wire to be clamped between the gland fixing nut and panel enclosure. To ensure that a good earth bonding
between the drain wire and panel case, a 20 mm shakeproof washer should be used, as shown in the termination
diagram below.

6. Connecting to the Panel
All panel terminal block connections support cable with a maximum cross section capacity of 2.5 mm2capacity.
Care should be taken to use the correct sized terminal screwdriver and not to over tighten the screws.
If stranded cables are used then care should be taken to ensure that all strands are contained in the terminal
block and that there are not any loose strands that may cause short circuits to other terminals or cables.
The mains connection should enter the enclosure via a knockout as near to the mains terminal block as possible
and should be segregated from all other wiring. Mains connection cables should be kept short and be secured
together with a cable tie near the mains terminal block to minimise the danger of them shorting to other parts of
the equipment if they become disconnected.
The mains terminal block contains a F1.6A L250V fuse and must be replaced only with a fuse of the same type.
The diagram below shows the recommended cable routing for connections to the panel. The diagram shows the
rear cable entry points used. If top cable entry points are used then a similar arrangement should be employed.
To avoid the possibility of a confusing array of fault conditions, it is best to connect the system gradually so that
faults can be cleared on one circuit before connecting another.
Polarity must be observed carefully on any terminals with + or - markings and end of line devices must be fitted
to all circuits which connect to terminals that have had the supplied, end of line devices removed.
All wiring should be checked carefully before applying power to the control panel.
Do not connect or disconnect wiring with the power on.

7. Front Panel Controls
The front panel contains controls for operating and programming the panel.
The “Lamp Test” and “Silence Buzzer” buttons can be operated at any time. (Access Level 1)
The “More Leak Events” and “More Events” buttons can be operated at any time when there are more events
than can be displayed on the screen. (Access Level 1).
The menu navigation buttons (1, 2, 3 and 4) can be used to enter the password to Access Level 2 (2222), which
then enables the “Silence Alarm (Acknowledge)”, “Re-sound Alarm”, “Reset”, ”Sound Alarms” and “Function”
button. This also gives the user access to the Access Level 2 menu facilities such as “Disabling” and testing parts
of the system.
Access Level 2 can also be entered by operation of the “Enable Control” keyswitch.
The internal panel buzzer will “beep” whenever a button is pressed.
The help “?” button offers additional information relating to the current status of the control panel. For example,
if the panel is in an Alarm or Fault condition then advice on the recommended action will be displayed when the
”?” button is pressed or if a menu function is being accessed then help relating to that function will be displayed
when the “?” button is pressed.
With the lid of the control panel open, Access Level 3 controls are revealed. These controls are strictly for service
personnel and should not be operated by the user under any circumstances. Opening the front cover also gives
access to the “PC” Connection Port for programming.
If the processor stops running or re-boots for any reason, the watchdog indicator “W/Dog Operated” will
illuminate as a record of this event, this indicator can only be reset by operating the “W/dog Reset” switch.
It is necessary under some circumstances (after a firmware upgrade for instance) to re-start the processors in
the panel. A reset switch is provided for this purpose labelled “Reset”.
A display “Contrast” adjust control is provided which can be adjusted to suit the lighting conditions or position of
the installed panel. This is a rotary control and can be adjusted with a small terminal screwdriver.
In order to change the configuration of the control panel, the configuration memory must be enabled. This is
done by switching the “Write Enable” slide switch from its normal, right hand position, to the left as indicated by
the arrow beneath it.
A warning is displayed on the LCD when the “Write Enable” switch is in the enabled position to prevent it from
being inadvertently being left in this position. This warning can be reset after the switch has been returned to its
normal position by pressing the front panel “Reset” button. If not reset, the warning will time out a short while
after the “Write Enable” switch is returned to the right hand position.
All of the Access Level 3 controls are recessed to avoid accidental operation but all can be accessed using a small,
terminal screwdriver or similar tool.

8. Powering the Panel
Never connect batteries before applying mains power first.
Ensure that the panel is free from swarf, wire ends, knockout blanks and any other debris.
Ensure that all cable connections to loops, sounder circuits and other inputs or outputs being used are correct
and that the wiring is formed tidily away from the surface of the circuit board before applying power.
The panel requires two 12 V 7 Ah sealed lead acid batteries. The batteries should be placed in the bottom of the
box with the terminals facing up and facing each other.
Batteries can be dangerous. Do not short the battery terminals to the enclosure or mounting plate. The polarity
of the battery connection should be checked carefully before proceeding.
Connect the batteries together first by fitting the battery link to the battery terminals nearest the back of the
enclosure.
Connect the red battery lead to the terminal of the left hand battery nearest the front of the enclosure and the
black battery lead to the terminal of the right hand battery nearest the front of the enclosure.
The supply from the battery is protected by a 3.15 Amp, 20mm glass fuse that will rupture if excessive current is
demanded from the battery by the control panel. This fuse is labelled F4 and is located on the underside of the
circuit board.
To replace the battery fuse, the power should be removed from the panel and the plate removed as described in
section 4. The fuse must be replaced with one of the same type.
Never connect batteries before applying mains power first.

Once all power connections are correctly made and power is applied, the panel is ready to start.
8.1. Configuration Data - Write Enable Switch
Panels have a memory “Write Enable” switch fitted. This switch is used to physically prevent the configuration
memory contents from being changed.
Before making any changes to the panel configuration, it is necessary to ensure that this switch is in the “Write
Enable” position. The “Write Enable” position is with the switch actuator set to the left in the direction of the
arrow under the switch.
When left in the “Write Enable” position, a notification message will be given on the Hydrosense ID display. This
warning message will disappear 1 minute after the switch has been turned off or can be cancelled immediately by
operating the front panel “Reset” button.

It will not be possible to perform the Autolearn sequence or transfer a configuration into the panel
from the PC (as described below) unless the configuration memory is “Write Enabled”.
It is also necessary to operate the “Write Enable” switch whenever any changes are made to the configuration
memory using the Access Level 3 “Edit Configuration” or “Set Times” menu options via the front panel controls.
8.2. Configuring the Panel (Autolearn – Initial Startup)
When supplied, the panel will contain no configuration and when power is first applied the display will show:
CAREFULLY slide the “Write Enable” slide switch (located behind the aperture in the bottom right corner of the

On a system, which has been Auto learned; inputs, outputs and field devices will be configured to the default
settings. Some of these defaults may be altered at Access Level 3 on the control panel. All can be altered via the
Loop Explorer PC (LE2) configuration utility.
It is quite common for mistakes to occur when addressing large numbers of devices and it is possible that some
devices may have been set to the same address. The control panel can detect devices that have been set to the
same address and will announce a “double address” fault if it finds any.
It is not possible for the control panel to tell which devices have been double addressed but to help find them,
enter Access Level 2 by entering the code 2222 or operating the key switch, go to the view devices option in the
menu, select view devices by loop and make sure that all of the devices that are expected are listed.
If there is one double address fault and one device missing from the list of expected devices then it is fairly
certain that the missing one is the one that has been addressed incorrectly.
It becomes a bit trickier when there are more than 2 devices with the same address or more than 1 double
address but using the principle above it will be possible to find the errors by a process of elimination.
It is always much quicker and easier to commission a system which has been addressed correctly and extra care
taken to fit devices with the correct address as per the installation plan will pay great dividends at the
commissioning stage.
If a fairly heavily populated loop is disconnected from the panel, the panel will report all of the devices
disconnected. Upon re-connection of the loop, the panel will find all of the devices again but it also has to run as
a Leak Detection control panel, service other parts of the system and re-initialise the devices that have been
detected. In the case of a large number of faults under these circumstances it is often quicker to get the system
back to normal by re-starting the panel by pressing the “Reset” switch (located with the door open and to the
right of the “Fuse Fail” LED.
8.3. Configuring the Panel (from PC)
To allow configuration from a PC it is necessary to have the Loop Explorer PC (LE2) configuration utility installed
on the computer and for the download lead (Part Number: IDAP-LEAD) to be plugged into the serial port of the
computer. The other end of the download lead should be connected to the “PC” connector which is exposed when
the outer door is opened and is located to the left of the Fuse Fail LED Indicator.
When configuring the panel from a PC, it is very important to ensure that the actual configuration of devices
installed matches the PC configuration. If this is not the case then there can be a bewildering array of missing
and/or unexpected devices, which can be quite confusing and difficult to diagnose.
If the exact site configuration is not known in advance, it is possible to upload an Auto-Learned configuration to
the PC, add text messages and any other changes required and then download this back to the control panel.
This method ensures that the configurations match, is likely to proceed without errors and provides a quick and
easy method of entering text and zone number information.
Panels that are configured from a PC can have default settings for devices changed so the system should be
thoroughly tested after a download to ensure that all devices respond as expected.
To retrieve a configuration from the panel and save it onto a PC, connect the IDAP-LEAD download lead to the PC
port of the panel and to the serial port of the PC. Open the Loop Explorer PC (LE2) configuration utility on the PC
and select “Connect to Hydrosense ID panel” from the four options that are offered by the opening screen. Click
OK and you will be given an option to save the file you are about to create.
Give the file a name that is easily identifiable with the site and the panel location/name. Once the configuration
file is created and the program is open, there is an option in the panel settings to enable the panel name to be
set and displayed on the panel.
Always keep a backup of configuration files with a different name to the original such as filename 01, filename 02
etc.

Once the file has been saved an option to use a dial up connection will be offered. If this facility is going to be
used, select yes and enter the telephone number that will need to be dialled to connect to the panel. If this is not
required select no.
Loop Explorer PC (LE2) configuration utility will now open with a blank configuration. Click on the
Connect icon, which is the third from the right in the row of icons along the top of the screen.
This will open the PC CONNECT screen. Click on the tick box in the column on the left labelled Sync then click the
button labelled Synchronise in the second row of icons on the PC CONNECT screen.
A dialog box will be displayed showing the file transfer process from the panel to the PC. After a few minutes the
file transfer will be complete. Close the PC connect box, click on the + sign next to the panel icon on the left then
click on the + sign next to the loop icon. This will now show all of the devices that are connected to the panel and
they can be viewed and edited as required by double clicking them. The file should be saved with an appropriate
file name once edited as required.
To transfer the modified file back to the panel, first switch on the “Write Enable” switch at the panel by moving it
to the left, click the connect icon at the top of the screen, put a tick in the box in the column labelled Sync and
click Synchronise. The file will now be sent back to the panel with any changes that were made on the PC. The
panel will display RECEIVING NEW CONFIGURATION, PLEASE WAIT… during the file transfer process and will then
display the start up screens as per the Auto learn sequence above.
When the file transfer has finished, switch off the “Write Enable” switch on the panel, enter Access Level 2 and
press the front panel reset button to clear the system fault message. The panel will now contain the modified
configuration from the PC.
9. Facilities Menu
A number of facilities are provided which can only be reached at Access Level 2 or 3.
Access Level 2 can be reached by entering the correct password (a 4 digit number) and pressing the enter button
or the “Enable Controls” key switch.
Access Level 3 can only be reached from Access Level 2 and only by entering the correct, 4-digit password then
pressing the enter button.
Panels that have not been configured, or have been configured using the Auto Learn option, have 2222 as the
default password for Access Level 2 and 3333 as the default password for Access Level 3.
Passwords can only be changed using the Loop Explorer PC (LE2) configuration utility.
The Access Level 2 password is required by the end user, to “Silence/Acknowledge”, “Resound Alarms”, “Sound
Alarms”, operate the “Function button” and to “Reset” the system.
Any persons responsible for safety and who have been trained and authorised to use the Leak Detection control
system should be made aware of the Access Level 2 password or given the enable controls key where applicable.
Without the Access Level 2 password or the enable controls key where applicable, it is not be possible
to control the Hydrosense ID Water Leak detection panel so it is most important that the responsible
person knows the password or is in possession of the enable key.
Main menu items available at access levels 2 and 3 are as follows:
ACCESS LEVEL 2
(2222)
ACCESS LEVEL 3 (3333)
Disablements
Edit configuration
View devices
Set times

10. Detection circuits
Hydrosense ID control panels are configured to communicate using only Hydrosense ID loop components.
Power is driven from the “LOOP OUT” terminals and is returned to the “LOOP IN” terminals, where it is monitored
for detection loop continuity.
If the loop is open-circuit (a cable fault or short circuit isolator operated), the panel will drive power from both
the “LOOP OUT” and “LOOP IN” terminals. This ensures that despite a single break or short circuit in the wiring,
all of the devices will still remain connected to the control panel. In the case of a short circuit, the short circuit
isolators will isolate the faulty section of the wiring and the panel will report devices between the isolators as
missing.
Both the “LOOP OUT” and “LOOP IN” connections of the panel are fitted with short circuit isolation so that a short
on the cable between these terminals and the first isolator fitted to the detection circuit will be isolated, leaving
the remainder of the circuit operational.
Detection loops should be wired in a screened 2-core cable and terminated at the panel using brass cable glands.
Detection loops should have the drain wire terminated at the cable gland, as described in Section 4.1

10.1. Fitting additional Detection Circuit (Loop Card: IDAP-LEC)
On a single loop Hydrosense ID panel an additional detection circuit (loop card) can be fitted, it must be compatible with
the existing detection circuit. Note: The system can only support a maximum of two loops.
To fit the Loop Card, the control panel must have mains and battery power removed.
The metal chassis should then be removed by removing the two fixing screws that hold it in place.
The Loop Card is supplied in a static dissipative bag and should remain in this bag until it is to be fitted.
As with all electronic components, this circuit board is very sensitive and can be easily damaged by electrostatic discharge.
Where possible, a static protective wrist strap should be worn when handling circuit boards. Where this is not available; it
is advisable to touch a surface that is known to be connected to the earth of the fixed installation.
The additional Loop Card mounts on the left hand side of the main board and fits into two connectors labelled X7 and X8.
There are two mounting pillars on the main board to which the additional Loop Card should be fitted using the M3
screws and fibre washers supplied.
After checking that the Loop Card is firmly located and making good contact with its connectors, the metal
chassis can be screwed back into place in the enclosure.
Unused detection circuits must have the "LOOP + OUT" to "LOOP + IN" and "LOOP - OUT" to "LOOP - IN"
terminals wired together to prevent open circuit faults from being reported.
The devices on the new detection loop should be added to the original configuration file using the Loop Explorer
PC (LE2) configuration utility and downloaded to the panel as described in section 8.3. If this is not done the
panel will report unexpected devices on loop 2.
CAUTION – If an Autolearn is done to detect the devices on the additional loop, any previous configuration such
as location text that had been allocated to the existing devices on the original loop will be erased. For this reason,
it is preferable to update the control panel configuration via a PC.

11. Panel Sounder Circuits
Two conventional sounder circuits are provided in the panel, each fused at 1 Amp. A 10KΩend of line resistor
monitors the circuits for open and short circuit faults.
Both circuits are configured to activate upon any Leak Detection condition and to de-activate when the “Silence
Alarm/ Acknowledge” button is pressed on the front panel or a “Silence input” is operated. Each sounder circuit
can be configured independently via the Loop Explorer PC (LE2) configuration utility or the front panel
pushbuttons (at Access Level 3).
This allows sounder circuits to be operated by different methods such as Zonal Alarm or via Cause & Effects.
11.1. Stage one and stage two delays
The sounder circuits can have a single or two-stage delay if required. The first stage of delay allows up to 5
minutes for the alarm to be acknowledged.
If the alarm is not acknowledged before the first stage delay expires, then the sounders will operate.
If the alarm is acknowledged during the first stage delay, the second stage delay (again up to 5 minutes) will
start.
If the alarm is acknowledged during the first stage delay and the second stage delay is zero then the sounders
will not operate.
If the alarm is acknowledged during the second stage delay, the second stage delay (up to 5 minutes) will start
and the sounders will operate at the end of the delay unless the panel is reset.
Activation of two or more devices producing a Water Leak action, an input configured to override output delays,
will override the delays and operate the sounders immediately.
12. Relays
Volt free changeover relay contacts rated at 30 VDC at 1 Amp are provided for ancillary switching functions in all
panels.
Under no circumstances should voltage or current outside of this limit be used with these contacts.
The default actions of these contacts as supplied from the factory are as described below: -
NAME
ACTION
LEAK DETECTION
Activates on any Leak Detection condition and remains active until panel is reset
FAULT
Activates on any fault or on total loss of power and clears when faults are cleared
ALARM
Activates on any alarm, de-activates when alarm silenced / acknowledged
Each volt free changeover contact can be reconfigured independently for other actions via the PC configuration
program or the front panel pushbuttons (at Access Level 3).
13. Remote Control Inputs
Five inputs are provided in the panel, which have default actions as described in the table below:
INPUT
DEFAULT ACTION
FLT
Operates outputs configured to operate on fault condition.
RES
Resets the control panel
INT
Operates all sounder outputs intermittently
CNT
Operates all sounder outputs continuously
SIL
Acknowledges the alarm (silences all sounders)
NOTE: The RES / INT / CNT / SIL inputs should only be available at Access Level 2. Care must be taken to ensure
these inputs cannot be operated without some form of access control.

All inputs can be re-programmed to have a different action, delay, zone and location message using the Loop
Explorer PC (LE2) configuration utility or front panel controls (at Access Level 3)
To activate the inputs, the “0V” connection is connected to the input(s) as shown below.
All inputs are non-latching as default.
The line impedance should be less than 50 Ohms for reliable operation.
14. Remote I/O Serial Bus
The Hydrosense ID control panel has a serial communications bus to which additional I/O, relay, sounder and
conventional detection zone boards may be connected. The serial bus also supports up to 15 repeater panels.
Up to 32 I/O units can be connected to the serial bus and these can be a mix of any type.
Limited numbers of these units may be connected to the panel’s Auxiliary 24 VDC supply however the fuse rating
of the Auxiliary supply and the effect of the extra power required on battery standby must be taken into
consideration. Full details of power consumption for devices that connect to the serial I/O bus can be found in
the Installation manuals of the individual devices.
Connection of remote I/O boards to Hydrosense ID panel.
14.1. 16 Channel I/O Board (ID-SIO-16)
The 16 channel I/O boards can be individually configured using the Loop Explorer PC (LE2) configuration utility to
modify its operation in response to Alarms or Cause & Effects as required.
Each channel can be programmed as an Input or an Output. When added to a control panel, all channels default
to Inputs (default action when activated will be FAULT). Any or all channels may be changed to Outputs via the
Loop Explorer PC (LE2) configuration utility. When channels are changed to Outputs (default action - DEFAULT
RING MODE). This means that they will switch on when a Leak Detection condition is present on the control panel
as COMMON ALARM, ZONED ALARM or 2-STAGE ALARM (see section 19.3.2).
Inputs to these boards are via Opto-Isolators, which offer good protection against electrical noise and transient
voltages. Channels configured as Outputs are Open Collector, so must be used with care to avoid damage by
shorting or sourcing too much current. For full details of 16 channel I/O boards refer to manual 3500041.
14.2. 8 way Relay Board (ID-SIO-8R)
The 8 way Relay Boards have individual, volt free changeover relay contacts which can be configured using the
Loop Explorer PC (LE2) configuration utility to operate in response to Alarms or Cause & Effects as required.
Relay contacts are rated at 30 VDC, 1 Amp. For full details of 8 way Relay Boards refer to manual 3500042.

14.3. 6 way Sounder Board (ID-SIO-6S)
The 6 way sounder board has 6 voltage reversing, monitored Sounder Outputs which can be programmed to
operate as required on response to Alarms or Cause & Effects.
The sounder board also have two programmable, volt free changeover relay contacts and two Opto-Isolated
Inputs all of which are also fully programmable via the Loop Explorer PC (LE2) configuration utility. For full details
of 6 way Sounder Board refer to manual 3500043.
14.4. 4 way Zone Board (ID-SIO-4Z)
The 4-way Zone Board has four conventional Detection Zones, two monitored Sounder Outputs and two
programmable volt free, Relay Contacts which default to Leak Detection and Fault actions.
The 4-way Zone Board is in effect a self contained 4 zone conventional control unit. For full details of 4 way zone
boards refer to manual 3500044.
14.5. Hydrosense ID Repeater Unit (IDAP-S-R-24 / IDAP-S-R-230)
The Hydrosense ID Repeater is a very cost effective, full function repeater panel that connects to the remote
serial I/O bus and provides full indication and control of all panels’ status and functions in a compact, slimline
enclosure.
Up to 15 Hydrosense ID Repeaters may be connected to the serial bus as well as any combination of the other
types of I/O boards up to a maximum of 32.
Hydrosense ID Repeaters have a low standby current consumption and can be powered by the Aux 24V output of
the Hydrosense ID control panel or 230 VAC (depending upon model purchased). For full details of Hydrosense ID
Repeater Units refer to manual 3500045.

15. Power Supply
The control panel is fitted with a 2.3 Amp power supply and battery charger capable of charging up to 9 Ah
batteries. A separate power supply should be used if larger batteries are required.
The power supply requires a 230 VAC mains connection to the fused, mains terminal block in the top left corner
of the back box.
The power is split between the charging circuit and power supply such that a maximum of 1 Amp is available to
charge the batteries if required, which leaves 2 Amps to run the control panel and peripherals. If the batteries are
fully charged and do not require any power, the full 3 Amps is available to run the control panel and sounder
load.
The power supply incorporates sophisticated monitoring of the condition of the power system. The battery
charging output is temperature compensated to maximise the service life of the batteries.
The following fault conditions are signalled at the control panel: -
•MAINS FAILED
•BATTERY DISCONNECTED
•BATTERY LOW VOLTAGE
•EARTH FAULT
The mains fuse fitted is a T1.6A 250V HRC 20mm type and must be replaced upon failure with a fuse of the same
type to maintain the safety rating of the power supply.
15.1. Aux. 24V Supply
A separately fused auxiliary 24 Volt output is provided for powering additional I/O boards or other equipment
connected to the Hydrosense ID system. When switching inductive loads such as relays, these should be
adequately suppressed using a reverse connected diode.
The “Aux. 24V” supply fuse is of the self-resetting type and is rated at 500 mA. Failure of the fuse is monitored
by the system and announced as "Aux. 24V” fuse failed.
The impact on battery standby duration must be carefully considered when using the “Aux 24V” Output. Constant
use of the full 500 mA capability of this output for instance would require an additional 15 Ah of battery capacity.
Ideally, use of the “Aux. 24V” Output should be restricted to powering a limited number of additional I/O boards
or switching equipment when an Alarm condition occurs.
15.2. 24V OUT Terminals
The terminals on the circuit board marked “24V OUT” should not be used for any part of the installation. These
terminals are reserved for powering additional equipment that is factory fitted only. Using these outputs to power
equipment outside of the panel enclosure will compromise the integrity of the system.
15.3. Remote PSU
The terminals marked “Remote PSU” are for the connection of a remote power supply. These terminals are used
on control panels that have an external power supply and larger batteries in cases where standby periods longer
than 24 hours are required.
There are two sets of terminals, which allow two transmission paths to be accommodated. A Power Fault Input is
also provided to signal faults from a remote power supply on the Hydrosense ID Panel.
15.4. Battery Capacity
To enable the system to continue to function in the event of a failure of the mains supply, batteries must be
fitted. These are not supplied with the control panel and must be purchased as a separate line item.
Batteries should be of the re-chargeable, sealed lead acid type. They should be new (less than six months old)
and sized according to the local codes of practice for the standby period required, preferably by measuring
quiescent and alarm loads for the particular hardware configuration installed or using the formula listed below to
calculate the required capacity.
The battery capacity required can be calculated using the following information.
This table shows the panel current consumption but does not take into account device loads, additional I/O
boards, or use of the “Aux. 24 Volt” output. Systems using these facilities should have their battery size
calculated according to the additional information below.
