ALCN-792MI SO Quad Loop Adder Module w ith ALCN-792D Daughter Board
The Quad Loop Adder module provides two SLC loops plus an additional two SLC 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 board. 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.

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 32, Figure 33 and Figure 34.
This is the addressable loop for all initiating devices. Wire the loop as shown in
Figure 32, Figure 33 and Figure 34.
If the loops are shielded, connect the shields to the terminals marked COM(-). To
prevent the board reporting a ground fault, do not connect shields on SLC lines to
earth ground.
Note: Unshielded wiring is preferred.
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.
