Alcn-792Miso Isolated Quad Loop Adder Module With Alcn-792D Daughter Board - Mircom FLeXNet FX-MNS-6000 Installation And Operation Manual

4.15 ALCN-792MISO Isolated Quad Loop Adder Module with ALCN-
792D Daughter Board
The 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-792MISO. The Quad Loop Adder module
may be mounted over the main fire alarm controller board 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.

RS-232 Debug Interface:
JTAG Port:
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.
The RS-485 cable is attached at P4 on ALCN-792MISO 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 P3 on ALCN-792MISO
to the next loop controller module cable from P4; if it is not used, leave without
connection.
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.
This is the addressable loop for all initiating devices. Wire the loop as shown
in Figure 33, Figure 34 and Figure 35.

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.
ALCN-792MISO:
• JW1: Factory use only. Leave open.
• JW2: Factory use only. Leave closed.
• JW3: 3 pin jumper. Normally set to 1-2, can be set to 2-3 to prevent noise
from CLIP System Sensor sounder bases on Loop 1. Pin 1 is marked
with a dot.
• JW4: 3 pin jumper. Normally set to 1-2, can be set to 2-3 to prevent noise
from CLIP System Sensor sounder bases on Loop 2. Pin 1 is marked
with a dot.
• JW6 on ALCN-792MISO: Factory use only. Leave closed.
ALCN-792D:
• JW1 - Normally set to 1-2, can be set to 2-3 to prevent noise from CLIP
System Sensor sounder bases on Loop 4.
• JW2 - Normally set to 1-2, can be set to 2-3 to prevent noise from CLIP
System Sensor sounder bases on Loop 3.
This connection if for factory use only.
