ICAC-306 Input Class-A Converter Adder Module

ICAC-306
All these pins comes with
red and black wires which
are connected to the
detection circuit on the
main fire alarm board. Red
is positive and black is
negative
Figure 7
There are no jumpers or cables to set on this module, just wiring from the converter (wires are
fixed here) to the Main Fire Alarm Board.
Initiating circuits must be wired from the ICAC-306 module to the Main Fire Alarm board. For
example, Initiating circuit 1 positive (red) and negative (black) wires are connected to the
positive and negative terminals (respectively) of Initiating circuit 1 on the Main Fire Alarm
Board. From the ICAC-306 converter Initiating circuits are wired out to the devices from the
positive and negative terminals marked DET OUT and the circuit return wires are brought back
to the converter module to positive and negative terminals marked DET RET.

Cable and Jumper Connections for Main Board, Core Board and Adder Modules
Remove this jumper if PR-300 is connected.
Cable from connector P1 of the RM-306 Relay Adder Module connects here.
Otherwise not used.
Remove this jumper if an RM-306 Relay Adder Module is used.
Shorted if there is no external unit on RS485. This jumper works as 'end of line'
jumper. If one or more units are connected on RS485, only short on the last
connected unit. JW4 on all other units should be left open.
Normally open. To reset the password, place jumper here and power down the
panel (both AC power and batteries). Then power up the panel again, the
password is restored to the default after system startup. Once the system has
reset, REMOVE the jumper from the pins at JW5.
Normally open to BLOCK configuration via modem, PC with a UIMA converter
module or a CFG-300 Configuration Tool. Place jumper here to ALLOW any type
of configuration.
Factory Use Only. Always Short.
