ALCN-792M Quad Loop Adder Module with ALCN-792D Daughter Board
The new Quad Loop Adder module provides two addressable loops plus an additional two loops as part of the
daughter board ALCN-792D which is mounted over the ALCN-792M. The Quad Loop Adder module may be
mounted over the main chassis of the FX-2000N Fire Alarm Panel or on any chassis that supports adder boards.
Refer to the Display and Adder Modules section for mounting applications. This module is mounted using four #6
screws and (if necessary) four 1 1/2" spacers.
Power
The power is supplied to the board via cable from the main fire alarm board or from
the previous loop controller module into the P1 POWER IN connector. Connect the
P2 POWER OUT connector to the next loop controller module or other adder
module. One power cable is supplied with this module.
RS-485:
The RS-485 cable comes attached at P3 and is either connected to P3 of the main
fire alarm controller module or connected from the previous loop controller module
or other adder board. If the next loop controller module is used, connect the
RS-485 out at P4 to the next loop controller module; if it is not used, leave without
connection.
DIP Switches:
Use the DIP switches to set the binary address of the board. SW1-1 is the lowest
significant digit and ON is active. For example, an address of two would be created
by turning SW1-1 OFF, SW1-2 ON and DIP switches SW1-3 to SW1-8 OFF. Refer
to Appendix C for DIP switch settings.
Loop 1:
This is the addressable loop for all initiating devices. Wire the loop as shown in
Figures 34, 35 and 36.
Loop 2:
This is the addressable loop for all initiating devices. Wire the loop as shown in
Figures 34, 35 and 36.
Jumpers:
A jumper is provided at JW2 for normal operation. To reset the board, leave the
jumper at JW2 and momentarily short the pins at position JW1.
RS-232 Debug Interface: This connection if for factory use only.
JTAG Port: This connection is for factory use only.
