Shield Aura - Class B SLC Loops

Class B SLC Loops
Class B loops may not be permitted in all
regions. Check local codes of practice before
using Class B SLC circuit configurations.
1. Connect Class B loops to both the IN and
OUT terminals of the terminal strip. Do not
insert more than one conductor per
terminal. Use wire nuts or other suitable
splice connectors to connect the Class B
loop cable to both the INand OUT
terminals.
2. When the loop is unused, the loop
termination jumpers provided with the
panel should be replaced with 14-22 AWG
SLCcable.
SLC cabling must be sized according to length
and device load to ensure that the voltage-drop
of the cable does not result in an inadequate
operating voltage on the circuit.
Refer to the Aura Fire Alarm Control Panel
Installation Manual (MAN-1431VS) for an
example of how isolators may be used on a
Class B circuit.
