Step 5: Remove the lid of the control unit
Release the 2 screws on the front of the lid, pull the lid down and
then lift it off.
Step 6: Fit the tamper switch and shroud
Fit the tamper switch assembly through the slot in the back of the
case (Figure 3). Connect the tamper switch to the PCB (Figure 2).
Also, for added security, fit the tamper shroud to the wall so that
when you mount the control unit, the shroud will surround the arm
of the tamper switch.

Step 7: Mount the control unit
Mount the control unit using at least 4 fixing holes (Figure 4) and
minimum 36mm long No10/5mm screws. Use only the designated
cable-entry holes.

Step 8: Connect all wired devices
Connect all wired devices such as keypads, a siren/strobe unit,
output device and external loudspeaker (Figure 2).
If you are using a plug-on module, fit and connect the device as
described in in the module’s installation instructions.
Step 9: Connect the battery
Note: Connecting the battery does not start the system.
Fit a 7Ah lead-acid battery in the bottom-right corner of the control
unit and secure with a strap provided.
Connect the battery leads to the battery (red to positive and black
to negative), and connect the other end to the PCB (Figure 2). Also
connect the transformer lead to the PCB (Figure 2).
Step 10: Connect the mains cable
WARNING: ENSURE THAT THE MAINS SUPPLY IS DISCONNECTED
AND ISOLATED.
L
N
Connect the mains cable to the
terminal block (Figure 5) and fit a
strain-relief tie. Confirm the mains
cable is routed as shown in Figure 1.
Do not apply power until after the lid
is re-fitted.
Figure 5. Mains connections
Step 11: Re-fit the lid, switch on and configure the
system
WARNING: During initial power-up, keypad sounders and any
internal loudspeaker may give an alarm tone. If you are working
at the top of a ladder, make sure that the sudden noise does not
startle you and cause a fall.
Re-fit the lid, then switch on the mains supply to the control unit.
Go through the initial configuration prompts and set up the system
as described in the Engineering Guide.
The default user code is 1234. You are prompted to specify an
installer code during initial system configuration.
PCB links, connectors and LEDs
The following sections provide information about the links,
connectors and LEDs shown in Figure 2.
a
SD card slot
A micro-SD card can be used to store camera images from a
compatible network camera, or to upgrade firmware or languages.
b
Plug-on module sockets
Several plug-on modules are available that enable, for example,
the control unit to communicate alarm information to an alarms-
receiving centre. Please refer to the Engineering Guide for a list of
supported modules.
c
RS485 bus termination link
If the control unit uses a single daisy chain to connect bus devices
and is at one end of the chain, fit a jumper across this link in the
control unit and in the last device on the bus. RS485 termination
can improve performance in electrically noisy environments.
The Engineering Guide gives further guidance.
d
Engineer keypad port
You can use an engineer keypad to configure the system, rather
than a keypad on the bus. An engineer keypad does not need an
address.
e
Reset codes link
You can use this link to reset the default user and installer codes
in the event that either has been forgotten. Please refer to the
Engineering Guide for details of how to use this link.
f
Mini-USB port
You can connect a PC to this port and use the Downloader software
to configure the control unit, or the Update Utility to update the
firmware.
g
Bus devices
Up to 20 devices such as keypads and expanders can connect to
the system bus. The installation instructions supplied with each
device provide details of how to install and configure the device.
The address of each device is set by the control unit.
Please refer to “Step 4: Install cabling” for guidance about bus
cabling. See also “RS485 bus termination link”.
h
Wired output
OP3 is an open-collector transistor output that users can switch on
or off to control external equipment. By default, OP3 is at 12Vdc
when inactive and 0V when active (this can be reversed from the
Installer menu).
Note: Radio outputs can also be used.
i
Network port
Connecting to a network allows you to, for example, configure
the control unit using the web interface, use network cameras to
capture images when an alarm occurs, and communicate alarms to
an alarms-receiving centre. Please refer to the Engineering Guide
for further information.
Note: The control unit’s network settings are configured from the
Installer menu.
j
Loudspeaker connections
If fitted, a loudspeaker mimics alarm tones and repeats setting and
entry tones. The loudspeaker must be min 16 Ohms.
Note:
• A loudspeaker is not a warning device as described by
EN50131-4.
• You can set the loudspeaker volume and partitions from the
Installer menu.
k
Siren/strobe unit
Please refer to the installation instructions provided with the siren/
strobe unit for connection details.
Note: Eaton radio siren/strobe units can be used instead of, or in
addition to, a wired unit.
l
Kick-start link
Ordinarily, the control unit starts only after the mains supply is
switched on, even if a battery is connected. If you want to operate
the control unit temporarily using only the battery or a 12VDC
supply), start the control unit by briefly shorting this link.
m
LEDs
• 3V3: Lit when the internal power supply is functioning.
• HB (heartbeat): Flashes approximately once every two seconds
to indicate normal operation.
• LNK/ACT: Flashes when the control unit is connected to the
network and there is network activity.
• COMMS: Lit when the plug-on module is communicating.
Maintenance
Inspect the control unit once per year as part of general inspection
of the whole system. At the control panel, check for any damage,
test the battery, check the action of the tamper switch and use the
Test menu to confirm signal strengths.
Please refer to the Engineering Guide for general guidance about
maintaining the whole system.
