Assuming all previous steps have been successfully followed, the F-Links will now be joined as a network and the
system will be fully operational, albeit not yet installed. Each F-Link will be set up with the factory default
configuration, and should display its own node name and signal meter, with no other messages or faults. The
signal meters should show regular pulses, as each Node announces its status to the network at approximately
30 second intervals. The processor status icon should rotate continually.
Quiescent (normal) display
Using a suitable tool or short length of wire, it is possible to temporarily trigger a selection of F-Link zone
inputs in order to help gain an understanding of how the system behaves. By default, each input is set as
'Normally Open', so connecting a link between the relevant 0v and IN terminals will trigger that zone. Full
details of the factory default configuration are given below.
2.3 Default configuration
The default configuration has been designed to meet the most common requirements and may be sufficient in
many cases. It can easily be changed if required by connecting a Windows laptop to the Master F-Link and using
the relevant software (see page 16).
2.3.1 Node name
Each F-Link has a text description, which can be up to 16 characters in length. This 'node name' is used to
identify the units across the system, and is added to all alarm, reset and fault messages associated with that
unit. By default the Master is named "MAIN BUILDING" and each Node is named "BUILDING {X}" where {X} is
the node address (1-15).
2.3.2 Input type
All zone inputs are volt-free. Each input of each F-Link unit can be individually set to operate as either Normally
Open (short to trigger) or Normally Closed (open to trigger). The default is Normally Open.
2.3.3 Relay output mode
Each of the four zones can have its relay outputs set to operate in 'Follow', 'Momentary', 'Latched' or 'Class
Change' mode. This setting applies globally to every F-Link on the system. By default, outputs 1-3 are set as
'Follow' and output 4 is set as 'Class Change'.
Follow
The output will clear when the input is cleared. This is the default mode for outputs 1-3.
Momentary
The output will clear after a set period (max 125 seconds), regardless of the input state.
Latched
The output will remain switched until manually reset using the keyswitch or external reset
input.
Class Change
The output will switch for a set period only (normally 2 seconds) with no message shown on
the display. This can be considered as a special 'transparent' version of the Momentary mode,
and is designed primarily for use with school class bells. This is the default mode for output 4.
2.3.4 Trigger/Clear messages
Two messages can be assigned to each input of each F-Link; one for use when the input is triggered, and one for
when it is cleared. These messages can be set individually for each F-Link on the system. Each message can be
up to 16 characters in length and is added to the 'node name' when displayed across the system. Any messages
not required can be left blank and will not be used.
The default messages are:
Zone Trigger Message
1
FIRE
2
FP FAULT
3
LOCKDOWN
4
CLASS CHANGE

Announcement pulse
Although no messages are displayed for any
zones set to 'Class Change' mode, the
optional F-Link paging transmitter uses these
messages for display on portable pagers, as
does the optional serial logging output; so
they should still be programmed.
