Installing i-on Control Units
Overview of PCB links, connectors and LEDs
The following sections provide information about the links, connectors and LEDs shown in
Figures 6 to 17.
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 Reset codes link
You can use this link to reset the installer and all user codes (e.g. in the event that codes
have been forgotten). All proximity tags, hold-up devices and remote controls are also
deleted. Please refer to the Configuration Guide for details of how to use this link.
c Engineer keypad port
Note: Not available in i-on Compact.
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.
d Plug-by communicator ports
Note: Not available in i-on30R+ and i-on Compact.
You can connect a plug-by communicator to these ports using an optional MISC-
COMPACK12 wiring harness (available separately).
By default, the outputs are 0V when active, and 12Vdc when inactive. Please refer to the
Configuration Guide for the default output type used for each output and programming
details.
Connect LF (Line Fail) to an output from the communicator that is 12Vdc when
communicator detects that there is a communications fault to the ARC, and 0V when no
fault is present.
If a dual-path (landline and mobile) communicator is used, such as a RedCARE STU, re-
program one of the plug-by outputs to type ATS Test, and wire that to the ATS Test input
of the communicator. Also connect Line Fail to the Line Fail output of the communicator,
as above. This is needed to comply with BSIA Form No. 175, April 2005. The control unit
generates an "ATE LF Single" alert if one network is unavailable, or "ATE LF All" if both
are unavailable.
Connect RR (Remote Reset) to an output from the communicator that indicates to the
control unit that a user can reset the system after a system tamper. The input must be
12Vdc for at least 100ms to indicate the reset, and 0v normally. For further details, see
"Remote Reset (Redcare Reset)" in the Configuration Guide.
Note: During system commissioning, confirm with the ARC that the communicator is
working correctly.
e Bus devices
Note: Not available in i-on Compact.
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.
