ALCN 792M ALCN 792MISO and Loop Adder Motherboard and Daughter Board Instructions ALCN 792M Quad Loop Adder and the ALCN 792MISO Isolated Quad Loop Adder module provide two loops plus an additional two loops as part of the daughter board ALCN 792D which is mounted over the The Quad Loop Adder module may be mounted over the main chassis of the Network Alarm Panel or on any chassis that supports adder boards This module is mounted using four 6 screws and if four 1 1 2 spacers Switches 1 2 power is supplied to the board via cable from the main chassis board or from the loop controller module into the P1 POWER IN connector Connect the P2 OUT connector to the next loop controller module or other adder module power cable is supplied with this module RS 485 cable comes attached at P3 on ALCN 792M and P4 on ALCN and is either connected to P3 of the main fire alarm controller module or from the previous loop controller module or other adder board If the next controller module is used connect the RS 485 out at P4 on ALCN 792M or P3 ALCN 792MISO to the next loop controller module if it is not used leave without the DIP switches to set the binary address of the board SW1 1 is the lowest digit and ON is active For example an address of two would be created turning SW1 1 OFF SW1 2 ON and DIP switches SW1 3 to SW1 8 OFF Refer to switch settings in table below is the addressable loop for all initiating devices Wire the loop as shown in the Fire Alarm Manual is the addressable loop for all initiating devices Wire the loop as shown in the Fire Alarm Manual the loops are

Board provides another two addressable loops when connected to the ALCN 792M Quad Loop Adder Board This daughter board is mounted over the ALCN 792M ALCN 792MISO using four screws and spacers provided Wire the two addressable loops on the ALCN 792D Daughter Board in the same as the ALCN 792M ALCN 792MISO addressable loops are wired the loops have shielding connect the shields to the terminals marked COM To prevent the board reporting a fault do not connect shields on SLC lines to earth ground Unshielded wiring is preferred 3 ALCN 792D Daughter Board mounting holes mount to board screws and
