AC BRANCH CIRCUIT
The ARIES™ Fire Alarm/Suppression Control Unit requires a separate, dedicated connection to
an AC branch circuit (120 Vac, 50/60 Hz, 3.2 A or 220/240 Vac, 50/60 Hz, 1.6 A) that must be
labeled "Fire Alarm." This branch circuit must connect to the line side of the main power
connection for the premises. No other equipment can be powered from the fire-alarm branch
circuit.
The branch-circuit wire must run continuously, without any disconnection devices, from the
source of AC power to the ARIES Control Unit. Over-current protection for this branch circuit
must comply with Article 760 of the National Electric Code and any other local electrical codes.
Use a minimum wire size of #14 AWG, with 600-volt insulation, for this branch circuit
