1. Introduction

The EXP-PSU is a remote power supply
intended for use in wired/wirefree alarm
systems controlled by the i-onEX range of
control units.

The power supply comprises a steel case
containing a pcb (printed circuit board) and
space for backup batteries.

The pcb holds the power supply circuits and
provides two sets of terminals for a bus
connection.

The pcb also provides a range of connectors
for outputs, plug-by communicators, and up
to 10 FSL (Fully Supervised Loop) or five
CC (Closed Circuit) zones.

The EXP-PSU provides monitoring
messages to the control unit over the
system bus. These messages include
Remote PSU Fault, Remote AC Fail, Remote
Battery Fail, and Remote Low Output
Voltage.

The EXP-PSU is designed and approved to
be used as part of a Security Grade 2 or 3
system.

About this Guide

This guide shows the simple procedure
required to physically install the EXP-PSU,
connect it to the bus, zones and outputs for
an i-onEX alarm system.

When you have completed the physical
installation please consult the i-onEX
Engineering Guide for details of providing a
bus address for the unit.

2. Before You Begin

Preparation

Before installation you should carry out a
survey of the site. You need to know how
many and what kind of detectors will be
connected to the EXP-PSU.

Siting the EXP-PSU

WARNING Ensure that the fixings are

strong enough to support the weight of the
EXP-PSU, its lid and two 17Ah lead acid
batteries. The total weight of the EXP-PSU
plus batteries can be up to 18kg.

Do site the unit:

Close to the equipment it is powering.

Upright, batteries at the bottom.
Within a protected area.

Do NOT site the unit:

In the entry or exit zones, or outside

the area covered by the alarm system.

Next to electronic equipment,

particularly computers, photocopiers or
other radio equipment, CAT 5 data lines
or industrial mains equipment.

Guided Tour

CAUTION: The printed circuit board for the
EXP-PSU has been tested for
Electromagnetic Compatibility (EMC).
However, when handling the pcb you must
take the standard precautions for handling
static sensitive devices.

Power Availability

Before connecting any devices to the EXP-
PSU, you must make sure that the unit can
provide sufficient current to power the
portion of the system it is connected to
during a mains failure for the time required
to meet the appropriate standard.

EN50131-1 Grade 3 requires 30 hours
provided that the control unit is fitted with
an ATS4 communicator capable of
transmitting a mains fail signal.

Note: When calculating the average load
during the standby time period you must
allow for at least two periods in alarm. To
take the worst case these two periods of
alarm should each be 15 minutes long, the
maximum permitted in EN50131-1 section

8.6.

PD6662 Grade 3, under the same
conditions, reduces the standby time
requirement to 12 hours.

The amount of current available from the
EXP-PSU depends on the size of battery
fitted and its health. The current taken by
the power supply‟s pcb, is given in

Technical Specifications – EN50131-6
Ratings on page 11.

The following calculation shows a simplified
example: in an alarm system with an EXP-
PSU which is connected to five i-kp01
keypads, and 40 wired PIRs and a wired
siren, the portion of the system powered by
the EXP-PSU takes the following total
quiescent current:

Device

Current

EXP-PSU PCB

50mA

40 x PIRs at 15mA each

600mA

3 x (wired expanders)

60mA

5 x i-kp01 at 30mA each
(backlights off)

150mA

Siren (quiescent)

25mA

Total

885mA

During an alarm, these figures become:

Device

Current

EXP-PSU PCB

100mA

40 x PIRs at 15mA each

600mA

3 x (wired expander)

60mA

5 x i-kp01 at 60mA each
(backlights off)

300mA

Siren (in alarm)

400mA

Total

1460mA

The total amp hours required =
(0.885 A x 29.5h) + (1.46A x 0.5h) =

26.83Ah
Note that this example assumes that the

communicator has its own power supply.
Two new, fully charged, 17Ah batteries can

provide the charge required by the portion
of the system in the example and would
meet the EN50131-1 Grade 3
requirements.

A single new, fully charged, charged 17A
battery can provide the charge required by
the example system for PD6662 Grade 3
requirements.

Note: All current drawn from the 12V Aux
terminals must be included in the overall
calculation.

CAUTION: Ensure that the system does not
demand more than the maximum current
available from the EXP-PSU during an
alarm, see page 11.

EXP-PSU

Page 4

Bus Cabling Requirements

Cable Type

In general, the EXP-PSU requires standard
7/0.2 un-screened four core alarm cable for
wiring the bus.

For maximum performance in harsh
environments use twisted pair screened
cable with a characteristic impedance of
100-120ohms eg: Belden 8132 or other
cable designed for RS485.

Use one pair for data lines A and B. Use the
other pair for 12V and 0V. For optimum
performance the voltage at the keypads
and expanders should be greater than 12V.

Screened cable may prove necessary if the
installation site has equipment that
produces high levels of R.F. (Radio
Frequencies). For example, welding
equipment is known to produce a large
amount of radio interference. If screened
cable is required, you should keep to the
following guidelines:

1. Avoid earth loops by connecting the
screen on the cable to mains earth at
the control unit but not at the keypad,
expander or EXP-PSU.

2. The continuity of the cable screen is
most important and screens MUST be
continuous along the full length of the
cable.

3. Where the cable enters any metal
enclosure, ensure the screen is isolated
from the case.

Cable Segregation

Segregate the bus cabling from any other
wiring, such as mains supply cables,
telephone cables, computer network cables
and R.F. cables. Use cable ties to keep
cables separated.

Keep the bus cable clear of cables supplying
sounders, extension loudspeakers or any
other high current devices.

Voltage Drop

In order for the system to work correctly,
the voltage at each device must NOT drop
below 10.5V even when running on the
standby battery. Cooper Security
recommend that the voltage at each device
should stay above 12V.

Standard 7/0.2 alarm cable has a
resistance of 8 Ohms per 100m per core.
The voltage drop is calculated using the
following formula: V Drop = Current drawn
x cable length x 0.08 x 2.

Table 1 on the next page shows the voltage
drop against the current drawn and cable
length.

The shaded area shows where the voltage
drop would cause the bus voltage to fall
from 13.8V to below 12.0V when using a
single core.

Reducing Voltage Drop - Method 1:

Double up the supply connections (12V and
0V), which will halve the resistance on each
core and therefore halve the voltage drop.
When using Table 1 to calculate the
expected voltage drop, simply divide the
voltage drop for a single core by two.

Reducing Voltage Drop - Method 2:

Supply the detection devices from the Aux
output on separate cores. This is the
preferred method of reducing voltage drop
as detectors generally operate at lower
voltages (9.5V). When using this method,
the network cable must have two spare
cores.

Connecting A Remote Power Supply

Figure 4 shows the recommended method
of connecting the EXP-PSU power supply.
The bus cable from the control unit
terminates on the EXP-PSU Bus In
connector and a new cable starts from the
EXP-PSU Bus Out connector. See page 6 for
more details.

3. Installation

Note: The installation steps listed below
assume that you have already decided on
the required location for the EXP-PSU.

Caution: Static Electricity

Like many other electronic products, the
EXP-PSU contains components that are
sensitive to static electricity. Try not handle
the PCB directly. If you must handle the
PCB, take the standard precautions against
damage by static electricity.

Step 1. Fit the Case

Fitting

To prevent access to the inside of the EXP-
PSU through the holes in the rear of the
case you must mount the unit on a wall or
other flat surface.

Locate and mark the position of the case.
Mark the position where the lid/back
tamper bracket touches the wall.

Fit the tamper shroud at the position where
the lid/back tamper touches the wall, see
Figure 5.

Figure 5 Fitting Tamper Shroud.

Mount the case vertically, as shown in
Figure 2. Use all three fixing holes. Use
No14/M6 screws at least 50mm long,
inserted into wall anchors appropriate for
the type of wall. Figure 2 shows the fixing
holes and cable entries.

WARNING Ensure that the fixings are
strong enough to support the weight of the
EXP-PSU, its lid and two 17Ah lead acid

batteries. The total weight of the EXP-PSU
plus batteries can be up to 18kg.

Protect the unit from dust and drilling
debris when drilling the fixing holes.

Installing the Lid/Back Tamper

Fit and connect the combined lid/back
tamper (provided). Ensure that the switch
is oriented as shown in Figure 6.

Figure 6 Lid/Back Tamper

Item 5 in Figure 3 shows the connector for
the lid/back tamper.

Note that to be approved at Security Grade
3 you must fit the lid/back tamper.

Step 2. Run Bus Cable

Please read “Bus Cabling Requirements on
page 4.

Step 3. Connect EXP-
PSU to the Bus

The EXP-PSU provides two bus connectors
(items 1 and 2 on Figure 3).

Figure 7 Bus Wiring EXP-PSU

Use the BUS IN connector to terminate the
bus cable from the part of the system that
is being powered by the control unit (or
other remote power supplies).

CAUTION DO NOT connect the 12V line of
the bus to BUS IN.

Use the BUS OUT connector to terminate
the bus cable to the portion of the system
being supplied by the EXP-PSU.

Addressing the EXP-PSU

The control unit assigns addresses to all
devices connected to the bus. You must
start this process off once the EXP-PSU is
connected, during the system power up.
See i-on160EX Engineering Guide for
instructions.

Step 4. Connect to Mains

WARNING: ENSURE THAT THE MAINS
SUPPLY IS DISCONNECTED AND ISOLATED
BEFORE MAKING ANY MAINS
CONNECTIONS. All mains electrical
connections must be carried out by a
qualified electrician and must comply with
the current local regulations (e.g. IEE).

Mains Cabling

Note: To avoid mains interference, the
mains cable must enter the EXP-PSU
through its own cable entry hole ( 9 in Fig

2) and must not be mixed with other

cables.

Mains Connection

Figure 8 shows the mains connection.
Connect to a suitable supply using a double
pole disconnect device in accordance with
EN60950-1.

Caution: Do not apply power at this

point.

Anchor the mains cable with a strain-relief
tie. There is a eye located near the mains
cable entry hole for this purpose.

Figure 8 Mains Connection

Step 5. Connect Wired
Zones

The EXP-PSU can be used for either four
wire Closed Circuit (CC) detectors, or two
wire Fully Supervised Loop (FSL) detectors.

Four Wire Closed Circuit Connections

Figure 9 shows the wiring for CCL zones on
the EXP-PSU.

Figure 9 EXP-PSU CCL Zone Wiring

Fully Supervised Loop Connections

Figure 10 shows the wiring connections for
FSL zones on the EXP-PSU. Note that the
resistance values shown are examples.

Figure 10 FSL Zone Wiring – EXP-PSU

The allowed values for Alarm Contact/End
of Line are: 4k7/2k2. 1k0/1k0, 2k2/2k2, or
4k7/4k7.

Note: Use the same pair of values for ALL
FSL wired circuits on the EXP-PSU.

When programming select the FSL resistor
values for the EXP-PSU in Installer Menu –
Detectors Devices – Wired Expanders - Edit Expander.

If you wish to connect two or more
detectors to a FSL zone, Figure 11 shows
the connections required.

Figure 11 Wiring Two Detectors per Zone

FSL.

Figure 12 shows an example of wiring
double doors with two door contacts to one
FSL zone. Each door contact is a reed
switch, connected between the outer
terminals. The inner (shaded) terminal is
not connected, and provides a spare
terminal.

Figure 12 Example: Wiring Two Door

Contacts to One FSL Zone.

Figure 13 shows an example of wiring a
trouble/masking output using the “3-

resistor method”. Note that you must use

2k2 and 4k7 resistors as shown. Other
values will not work (See System Options –

Masking in the i-on160EX Engineering
Guide).

Figure 13 Example: Wiring a

Trouble/Masking Zone, 3 Resistor Method.

Step 6. Connect Wired
Outputs

Remote Loudspeaker (Optional)

If you wish to add a 16 Ohm wired
Loudspeaker unit, then connect it as shown
in Figures 14. Do not connect another
loudspeaker in parallel.

Figure 14 Connecting Wired Peripherals

Note: Loudspeakers are not warning
devices as described by EN50131-4.
Although loudspeakers may mimic alarm
tones, they also give alert tones and other
progress tones when setting and unsetting
the alarm system.

During normal operation any loudspeakers
connected to the EXP-PSU repeat setting
and entry tones for the partition that the
unit is allocated to. During an alarm the
loudspeakers repeat alarm tones.

Each 16 Ohm loudspeaker draws up to
280mA in operation. If there is more than
one loudspeaker connected to the EXP-PSU
then the +12V line on the Bus Out
connector may not be able to supply
sufficient current during an alarm.

Wired Outputs

The EXP-PSU provides connections for up to
four transistor driven outputs. By default
the outputs are 0V when active, +12V
when inactive. If you wish to reverse the
polarity of these outputs see Changing the

Polarity of a Wired Output in the i-onEX Engineering
Guide. Figure 15 shows an example of using

an expander output to drive an LED.

Figure 15 Using EXP-PSU Wired Outputs.

If required you can connect an i-rc01 relay
card to the pins immediately above the
output terminals (see 12 in Figure 3) or
directly to the output terminals. The i-rc01
provides four voltage free outputs that
mimic OP1 to OP4.

Step 7. Fit a Plug-By
Communicator

The EXP-PSU can be connected to a
separate communicator or speech dialler
(for example, the Scantronic 8400, 660,
RedCare GSM or RedCare Dual Com).
Figure 16 shows the connections provided
by the communications wiring harness.

Each output pin of the communications
connector on the EXP-PSU follows the state
of the corresponding pin on the control
unit. These EXP-PSU communication
outputs cannot be programmed
independently of the control unit
communication outputs. Note that the
output types shown in Figure 16 are the
Factory default types. See the i-onEX
Security System Engineering Guide for
details on how to change the defaults on
the control unit (and, in consequence, on
the EXP-PSU).

Figure 16 Plug-By Communicator Wiring

Note: Comms O/P4 will be active when the
system is unset. This is normal.

To fit a communicator, follow the
instructions below.

Caution: Follow the instructions in the order

shown, or you may damage the EXP-
PSU and/or communicator.

1. Disconnect mains power from the EXP-
PSU, remove the case lid, and
disconnect the battery (if the system
has already been installed).

2. Make any necessary connections from
the communicator to the communication
wiring harness. The default is a 12V
positive voltage when the output is
inactive.

Refer to the next section if you are

using a dual-path communicator.

3. Plug the Communication Wiring Harness
onto the communications connector on
the main PCB.

If the system has already been installed:

4. Re-connect the battery.

5. Fit the case lid.

6. Apply mains power.

7. Test communicator operation.

Note: You will need to speak to the ARC in
order to confirm that the communicator has
worked correctly.

Line Monitoring for a Dual-Path
Communicator

If a standalone dual-path (landline and
mobile) communication device, such as a
RedCARE GSM, is connected to the plug-by
connector, you need to do the following to
obtain correct line fault reporting that
complies with BSIA Form No.175, April
2005:

1. Reprogram one of the plug by outputs
to type “ATS Test” and wire that output
to the ATS Test input of the
communicator.

2. Wire the Line Fault output of the
communicator to the Line Fault input of
the plug-by connector. The
communicator must provide +12Vdc to
indicate a line fault (for example, if the
Line Fault output at the communicator
uses a relay, connect the common
terminal of the relay to +12Vdc and the
normally-open terminal to the Line Fault
input of the plug-by connector).

The control unit will generate an "ATE L.F.
Single" alert if only one of the networks is
not available, or "ATE L.F. All" if both
networks are not available.

Step 8. Fit and Connect
Battery

Fit either one to two 17Ah Lead Acid
batteries into the battery compartment in

EXP-PSU

Page 10

the bottom of the EXP-PSU. Use batteries
whose case material has a minimum rating
of UL94V-2 in order to comply with
EN60950 (this standard applies because of
the energy content of 17Ah batteries).

See Figure 17. See page 3 for example
calculations of battery requirements.

WARNING 17Ah lead acid batteries
weigh 6kg each. Do NOT drop.

Connect the battery leads, red to the
positive, black to the negative terminals of
the battery. Connect the other ends of the
leads to either BATT1 or BATT2 (16 and 17
on Figure 3).

If you are fitting only one battery then
connect it to BATT1 (the lower set of pins)
and disable alerts on BATT2 (see the i-onEX
Range Engineering Guide).

Figure 17 Fitting the Batteries

Note: Connecting the batteries without
mains power will not start the system. (See
“Programming Before Installation” in the i-
on160EX Engineering Guide.)

Step 9. Initial Power-Up

Please see the i-onEX Security System
Engineering Guide for an explanation of bus

addressing.

When you apply power to the unit you may
notice the DIAG LED flashing (see 26 on
Figure 3). The LED gives one, two, three or
four flashes a second. Each of these
sequences has the following meaning.

No. Flashes

Meaning

One

Communication with control
unit over bus is OK

Two

No communication over the
bus in the last 10 seconds.

Three

No bus address allocated to
EXP-PSU

Four

No poll request received
from control unit in the last
minute.

The other status LEDs on the pcb (26 in
Figure 3) have the following meaning:

MF

Red=No mains AC.

LB

Amber = Absent or faulty
battery

12V

Red=12V fault

When glowing the following LEDs indicate
possible short circuits in the cabling.

Comms fuse
fail (3 in
Figure 3)

Red=communication outputs
failed. See Note 1

Aux 1 fuse
fail (8 in
Figure 3)

Red=Aux 1 fuse blown. See
Note 2

Aux 2 fuse
fail (13 in
Figure 3)

Red=Aux 2 fuse blown. See
Note 2

Bus OUT
fuse fail (24
in Figure 3)

Red=The output power on
the bus has failed. See Note
1

Notes:

1. These outputs are protected by

polyswitches, which will reset themselves
when the short is removed.

2. These outputs are protected by F-1A

20mm fuses which must be replaced once
the short is removed.

Step 10. Re-fit The Lid

Assemble and close the EXP-PSU:

a) Fit the lid of the EXP-PSU into the
back of the case (see Fig 18).
b) Fit and tighten the lid fixing screw.

Figure 18 Replacing the EXP-PSU lid.

4. Maintenance

The EXP-PSU should be inspected at least
once per year. At each inspection:

Check the unit for obvious signs of

damage to the case or its lid.
Check the action of the back tamper.

Check the condition of the standby

battery.
Check the cabling to EXP-PSU

expander(s) for signs of damage or

wear.
Test any sounders.
Note that if you wish to find the location of

any keypad or expander you can employ
the Test – Locate Bus Device option in the
Installer Menu. Use this option to make a
selected bus device give a continuous tone
from its sounder. Once you have found the
bus device you can silence the tone by
opening the case and so activating the
device‟s tamper.

EN50131-6 ratings

The EXP-PSU provides space for two 17Ah
batteries, giving a total of 34Ah charge.

Under EN50131-1 for Security Grade 3
installations the required battery standby
time is 30 hours, provided the system is
fitted with an ATS4 communicator capable
of transmitting a mains fail signal

This means that all the devices powered by
those backup batteries, within the EXP-
PSU, including the EXP-PSU itself, should
together draw no more in total than an
average of 1.1A over a 30 hour standby
time. Note that for Security Grade 3 the i-
on160EX or EXP-PSU must use a plug-by
communicator, which may have its own
power supply.

Under PD6662, battery standby time
requirements for Security Grade 3 drop to
12 hours, provided the system is fitted with
an ATS4 communicator capable of
transmitting a mains fail signal.

For Security Grade 2 the required battery
standby time is 12 hours. However, the
total average current available over 12
hours from the EXP-PSU batteries is limited
by the power supply to 1.5A. (The current
is limited to 1.5A because when mains is
present the 3.0A power supply reserves
2x750mA to recharge batteries, leaving

1.5A available to supply the system.)
