Supervised, nonpower-limited circuit
Command Input Circuits (alarm polarities shown)
• CMD1 - TB6 Terminals 3(+) & 4(-) are input terminals and Terminals 1(-) and 2(+) are output
terminals which provide feed through of the NAC circuits to NAC devices down stream
• CMD2 - TB7 Terminals 3(+) & 4(-) are input terminals and Terminals 1(-) and 2(+) are output
terminals which provide feed through of the NAC circuits to NAC devices down stream
• CMD3 - TB2 Terminals 1(+) & 2(-) are input terminals for contact closure only
• CMD4 - TB3 Terminals 1(+) & 2(-) are input terminals for contact closure only
• CMD5 - TB4 Terminals 1(+) & 2(-) are input terminals for contact closure only
Operation: CMD1 & CMD2 circuits are independently field programmable to activate amplifiers
on NAC polarity reversal or contact-closure. IMPORTANT! When CMD1 and CMD2 are config-
ured for reverse polarity, the NAC cannot be Coded.
CMD3, CMD4 and CMD5 are fixed to activate on contact closure only
Power-limited and supervised circuitry
