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.

Tamper switch: 
Ensure correct 
orientation

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.

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.

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.

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.

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.

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.

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.

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.

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”.

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.

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.

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. 

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.

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.

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.
