Input Point Module (AFI5100)
1.7 Links and Jumpers
The following table outlines the link settings for the AFI5100 :
Link Description Value
LK1, LK2 Links 1 and 2 are used to configure
whether Fire Over-ride (FOR) will oper-
ate in Enhanced FOR mode or Normal.
Enhanced mode also requires the
connection of a supervision circuit to
the Fire Over-ride Input. To enable Normal
Mode:

LK4, LK6 Links 4 and 6 control whether Fire
Over-ride (FOR) is enabled.
If the links are set to FOR operation,
activation of the FOR input will cause
the outputs to return to the NO position.
If the links are set to the off position,
FOR input will have no effect on the
state of the output relays. FOR operation

LK3, LK5 These auxiliary links have been included for further enhancement of the system.
LK7 LK7 affects the reset action when the
RESET link (LK9) is set and the power
turned on.
See LK9 below for a description of how
to reset the unit.
LK7
If the jumper on Link 7 is set as shown,
it is set to “Full Reset” mode.
LK7
If the jumper on Link 7 is taken off, it is
set to “Partial Reset” mode.
LK8 This is a General Purpose links that has been included for further enhancement
of the system.
LK9 Memory Clear and Reset
Setting LK9 and turning the power off and on will reset the IPM. A full or partial
reset can be achieved by setting LK7 on or off.
If LK7 is set, the IPM will fully reset and any firmware loaded into the memory will
be erased. You will need to re-program the IPM with firmware again before it can
operate.
If LK7 has the jumper removed, the microcontroller will be rebooted but the firm-
ware will remain in memory.
LK10 EOL Termination (Bus)
This link allows the RS485 BUS com-
munications channel to be terminated
in noisy or lengthy comms.
Note: Units located at the end of bus
lines only should have this link set. RS485 BUS port
not terminated.

RS485 BUS port
terminated.

LK11 – LK14 FOR Activation
These links allow FOR activation to be
enabled or disabled for each individual
relay output.
Enabling Fire Override for a relay
means that when the FOR input is
activated, the relay output switch to the
NO position.

LK12
In the above diagram LK11 (Relay 1) is
set to FOR Enabled and LK12
(Relay 2) is set to FOR Disabled.
